Posted on 27. Mar, 2012 by in Acura Canada

The 2013 ILX family includes 3 graphic models: ILX 2.0L, ILX 2.4L and ILX Hybrid. Each indication offers a singular powertrain and a singular character.

ILX 2.0L
The indication line starts off with a ILX sedan, that is powered by a 2.0-liter 4-cylinder engine that is new to a Acura brand. Fitted with a customary Sequential SportShift 5-speed involuntary transmission, a 2.0L offers a good mix of altogether opening and fuel efficiency.

The singular beyond cam (SOHC) 2.0-liter inline 4-cylinder has 16 valves, i-VTEC® and a specifically tuned dual-stage intake manifold. The 2.0L produces 150 horsepower during 6,500 rpm, and 140 lb-ft of torque during 4,300 rpm. The ILX with 2.0L has an EPA-estimated* city/highway/combined fuel economy rating of 24/35/28 miles per gallon. The engine conforms to Ultra Low Emissions Vehicle (ULEV-2) in all US states as good as conforms to Advanced Technology Partial-Zero Emissions Vehicle (AT-PZEV) standards in California.

The ILX 2.0L sedan facilities a customary electronically-controlled Sequential SportShift 5-speed involuntary smoothness with steering-wheel-mounted paddle shifters. In serve to Grade Logic Control and Shift Hold control, a ILX also incorporates Cornering G Shift Control, that suppresses neglected upshifts when a automobile is cornering aggressively.

ILX 2.4L
With regards to performance, a indication line is surfaced by a ILX 2.4L that is powered by a 2.4-liter 4-cylinder engine that generates a some-more performance-minded pushing experience. Offered exclusively with a 6-speed close-ratio primer transmission, it is a transparent choice for a fan driver.

The DOHC engine offers a operation of innovative facilities to assistance broach a mixed of performance, fuel potency and low emissions. The 2.4-liter inline 4-cylinder engine facilities Acura’s i-VTEC® “intelligent” valve control complement that pairs Variable Valve Timing and Lift Electronic Control (VTEC®) with Variable Timing Control™ (VTC™). The i-VTEC® complement delivers softened low-rpm torque, clever high-rpm appetite and superb fuel efficiency. The aluminum powerplant produces 201 horsepower during 7,000 rpm and 170 lb-ft of torque during 4,400 rpm.

The ILX 2.4L has an EPA-estimated* fuel economy rating of 22/31/25 mpg (city/highway/combined). In gripping with Acura’s proven joining to a environment, a ILX 2.4-liter engine meets despotic Ultra-Low Emission Vehicle (ULEV-2) tailpipe emissions standards.

ILX Hybrid
The ILX Hybrid is a first-ever hybrid automobile from Acura, powered by a fifth-generation of Honda’s integrated electric engine system. The Hybrid puts clever importance on fuel efficiency, yet with a CVT smoothness (that integrates SportShift primer mode), it lives adult to Acura’s repute for delivering an enchanting pushing experience.

With a ultra-efficient 1.5-liter i-VTEC® inline 4-cylinder engine with integrated electric engine and Continuously Variable Transmission (CVT), a ILX Hybrid has EPA-estimated* fuel economy of 39/38/38 mpg (city/highway/combined). A driver-selectable “ECON” pushing mode alters a Drive-by-Wire™ stifle complement response curve, to assistance a motorist work a ILX Hybrid with even larger efficiency. The ILX Hybrid has a ULEV-2 emissions rating, and AT-PZEV (Advanced Technology Partial Zero-Emission Vehicle) models as approved by a California Air Resources Board (CARB) are accessible in California and states that have adopted California Zero-Emission Vehicle regulations.

Recommended to work on Premium Unleaded fuel, a 1.5L engine has a 10.6:1 focus ratio for total appetite and twin hint plugs in any cylinder for rarely fit combustion. The integrated electric engine consists of an ultra-thin DC brushless electric engine mounted between a gasoline engine and a Continuously Variable Transmission. An Intelligent Power Unit (IPU) stores electric appetite in a lithium-ion battery container and controls a upsurge of electricity to/from a electric motor. The gasoline engine and electric engine mix to furnish limit outlay of 111 horsepower during 5,500 rpm and 127 lb-ft of torque between 1,000-3,500 rpm.

The ILX Hybrid’s integrated electric engine allows a regenerative braking complement to retrieve additional appetite during deceleration, while also permitting a electric engine to propel a

ILX 2.0L Powertrain

The ILX Sedan is powered by a 2.0-liter engine that is new to a Acura line. The inline 4-cylinder engine has a operation of facilities that revoke friction, raise emissions opening and maximize fuel efficiency.

Using a singular beyond camshaft (SOHC) pattern cylinder conduct with 16 valves, a 2.0L also facilities i-VTEC® and a specifically tuned dual-stage intake manifold. The 2.0L engine produces 150 horsepower during 6,500 rpm, 140 lb-ft of torque during 4,300 rpm and has a ULEV-2 emissions rating. The EPA-estimated* city/highway/combined fuel economy rating is 24/35/28 mpg.

CYLINDER BLOCK

To rise high appetite outlay along with high fuel efficiency, a 2.0-liter engine is done to be compact, lightweight and low in handling friction. Ferrous spin-cast cylinder sleeves, a slight breadth camshaft chain, and a sequence box with a built-in oil siphon assistance make a engine compact. To make a engine rarely rigid, endless research was used to strategically position reinforced areas in a aluminum block. A lightweight and unbending steel crankshaft is used with an integrated high change ratio. An aluminum oil vessel with integrated stiffeners serve adds to engine rigidity.

A operation of friction-reducing technologies urge a potency of a 2.0L engine. The skirts of lightweight aluminum pistons underline a molybdenum outdoor coating practical in a dot-pattern to revoke altogether attrition as a pistons pierce within a cylinder bores. A plateau honing technique creates an ultra-smooth aspect to revoke a attrition turn between a pistons and a cylinders. This 2-stage machining routine uses twin harsh processes instead of a some-more compulsory singular honing process, and enhances a long-term wear characteristics of a engine. Ion-plated piston rings and low flexibility (0W-20) oil are also used to revoke friction.

NOISE, VIBRATION HARSHNESS (NVH) CONTROL

The 2.0L 4-cylinder engine has an array of facilities designed to revoke NVH. The pressure-cast cylinder block’s high acerbity helps to conflict vibration. A singular change missile is used to well-spoken a fundamental quivering common in large-displacement inline 4-cylinder engines. A self-adjusting, silent-type camshaft expostulate sequence and twisted appendage expostulate belt also assistance revoke NVH.

Connecting Rods

To minimize weight and size, high-strength joining rods are used. The rod and top are fake as a singular territory during a production process, and afterwards are crack-separated to emanate an accurate fit between a twin mating surfaces. This crack-separation pattern allows for a rejecting of normal joining rod missile pins, given a joining rod bolts can be pointing machined to fit a top to a rod. The finish outcome is a joining rod that is 13 percent lighter and has a 20 percent smaller cranky territory than a normal rod— ensuing in rebate rotating mass inside a engine and rebate space assigned by a joining rod.

The 2.0L engine uses a movement of a innovative i-VTEC® valvetrain complement that includes varying intake valve operation to grasp clever opening and glorious fuel efficiency. At low engine speeds, usually one intake valve in any cylinder operates, while a second intake valve stays closed. At high engine speeds, a i-VTEC® complement thatch together both sides of a rocker arm to concede both intake valves to open during a same time. The i-VTEC® complement is means to switch valve timing era regulating a hydraulic actuator.

The i-VTEC® switch-over from a low-speed valve timing to a high-speed valve timing occurs between 1,000 rpm and 3,500 rpm (depending on engine load) to urge appetite characteristics in a many frequently used engine speed range. To best compare a some-more assertive high-speed valve timing, a shiver valve handling a non-static intake plural switches tract length from prolonged to brief during 5,000 rpm.

Engine RPM, volume of stifle opening, automobile speed and rigging preference all cause into a ILX’s i-VTEC® valve timing. A Drive-by-Wire™ stifle control system, atmosphere upsurge meter, dual-stage atmosphere intake and hit sensor concede a Powertrain Control Module (PCM) to emanate a well-spoken transition between a twin modes of i-VTEC® operation.

To softened foster a blending of fuel with a incoming air, a 2.0L has a winding intake pier design. This vital bend not usually promotes softened air-fuel mixture, yet it is also designed to softened mix a rebate around a hint plug, for a some-more fit explosion routine and augmenting fuel efficiency.

Dual-Stage Intake Manifold

The 2.0L engine creates use of a dual-stage mixed intake plural that utilizes twin intake runners for any cylinder— with one curtain longer than a other. Below 5,000 rpm, usually a longer runners broach atmosphere to a cylinders (thus holding advantage of an sluggishness outcome of a prolonged intake path). Above 5,000 rpm, shiver valves within a bores of a brief runners open to concede a thoroughfare of additional atmosphere to a cylinders. This has a outcome of boosting midrange and high-rpm appetite by utilizing a sluggishness outcome during both low and high rpm.

EXHAUST System

To revoke tools count and save weight, a 2.0L engine’s cylinder conduct integrates a cast-in empty plural that eliminates a need for a apart bolt-on empty manifold. For softened emissions performance, a catalytic converter bolts directly to a cylinder head, ensuing in faster light-off and some-more finish acclimatisation of a empty gases. The complement employs a new high-density catalytic converter (with revoke use of changed metals) for softened light-off opening along with reduced hydrocarbons and oxides of Nitrogen (NOx).

5-Speed Automatic Transmission

The ILX with 2.0L engine facilities an electronically-controlled Sequential SportShift 5-speed involuntary transmission. The computer-controlled smoothness provides well-spoken shifts and has rigging ratios that are closely matched to a outlay of a engine assistance maximize performance. The smoothness incorporates refinements that revoke noise, save weight and raise fuel economy.

To urge fuel economy while progressing a high turn of drivability, a 5-speed involuntary smoothness includes an active lock-up torque converter. With a accurate control afforded by a linear solenoid, a complement expands a speed and stifle sourroundings operation in that torque converter lock-up can be automatically engaged.

The 5-speed smoothness can be tranquil by a straight-gate console-mounted shifter or a racing-inspired steering circle mounted paddle shifter complement that works whenever a smoothness is in possibly of a twin involuntary modes. The Sequential SportShift 5-speed smoothness can be operated in twin opposite entirely involuntary modes with a console-mounted straight-gate shifter. The D (or “Drive”) mode is ideal for many pushing situations, and combines fuel potency with well-spoken operation and manageable appetite when needed. The S (or “Sport”) mode is for some-more performance-oriented driving, and facilities some-more assertive change mapping to keep engine rpm aloft for larger acceleration and response.

In serve to Grade Logic Control and Shift Hold control, a ILX also incorporates Cornering G Shift Control. All of a smoothness proof systems work together to automatically change change timing formed on pushing conditions. To urge powertrain fibre and revoke rigging sport on high grades, Grade Logic Control complement uses sensors that guard stifle position, automobile speed and acceleration/deceleration. These inputs are compared with a map stored in a smoothness computer, permitting a complement to settle when a automobile is on an slip and adjust a change report for softened climbing appetite or downhill engine braking.

Shift Hold Control keeps a smoothness in a stream (lower) rigging ratio when assertive pushing is detected, as in a box of decelerating during a dilemma entry. Shift Hold Control leaves a framework composed (as can be generated by additional shifting) and ensures that appetite will be immediately accessible (without a downshift) during a dilemma exit.

Cornering G Shift Control monitors a speed of any behind circle exclusively to settle when a ILX is turning. When a complement detects a sufficient speed differential between a behind wheels, it will conceal an neglected upshift. This prevents a smoothness from upshifting during a corner, that could dissapoint a framework change and would afterwards need downshifting again during a dilemma exit when a stifle is applied.

Temporary Manual Operation in “Drive”
Whether in Drive or Sport mode, special smoothness proof programming allows a use of a steering-wheel-mounted paddle shifters. When a motorist operates a steering wheel-mounted paddle shifters while in Drive, a smoothness responds to a driver’s change authority and afterwards earnings to a normal entirely involuntary Drive mode if serve paddle change inputs are not done within a brief time. This special proof creates it easy for a motorist to authority a discerning downshift but withdrawal a comfort of Drive mode.
When in Sport mode, use of a paddle shifters puts a smoothness into full primer mode that stays until another mode of operation is comparison with a console-mounted shifter.

Manual Mode
By relocating a core console-mounted rigging selector push rearward to a detent labeled “S,” a smoothness is shifted into Sport mode. This mode offers involuntary operation with some-more assertive change mapping. A lift on a racing-inspired paddle shifters (mounted on a behind side of a steering wheel) places a smoothness in entirely primer mode. A digital arrangement in a tachometer face indicates that rigging a smoothness is in.

To forestall mistreat to a powertrain when a smoothness is paddle shifted by a driver, a complement will stop potentially deleterious shifts. As an total haven measure, a Powertrain Control Module (PCM) can also cut off engine fuel upsurge to forestall over-revving. If fuel cut-off is deficient to forestall engine over-revving, as might be probable when a automobile is on a high downhill, a smoothness will automatically upshift to forestall damage. On downshifts, a smoothness will not govern a motorist authority that will over-rev a engine.

For softened stop-and-go opening and to forestall “lugging” a engine, a Sequential SportShift smoothness will automatically downshift to First rigging even yet a smoothness has been left in a aloft gear, (except in Second gear) as a automobile comes to a stop. In Manual Mode, when entrance to a stop in Second gear, a automobile will start in Second rigging as well.

With regards to performance, a indication line is headed by a ILX 2.4L that is powered by a 2.4-liter DOHC i-VTEC® 4-cylinder engine. The ILX 2.4L is accessible exclusively with a 6-speed primer smoothness propitious with a short-throw shifter assembly. Designed to be compress and lightweight, a primer smoothness has also been engineered to yield a accurate change action. The ILX 2.4L also includes a purchase complement with a torsion resource that enhances excellence in terms of rendezvous and feel.

The 2.4-liter engine offers a operation of innovative facilities to assistance broach a mixed of performance, fuel potency and low emissions. The 2.4-liter inline 4-cylinder engine facilities Acura’s i-VTEC® “intelligent” valve control complement that pairs Variable Valve Timing and Lift Electronic Control (VTEC®) with Variable Timing Control™ (VTC™). The i-VTEC® complement delivers softened low-rpm torque, clever high-rpm appetite and superb fuel efficiency. The aluminum powerplant produces 201 horsepower during 7,000 rpm and 170 lb-ft of torque during 4,400 rpm.

The ILX 2.4L has an EPA-estimated* fuel economy rating of 22/31/25 mpg (city/highway/combined). In gripping with Acura’s proven joining to a environment, a 2.4L engine meets despotic Ultra-Low Emission Vehicle (ULEV-2) tailpipe emissions standards.

Engine Block

The 2.4L engine facilities a compress aluminum retard with cast-in iron cylinder liners— a pattern famous for a light weight, high acerbity and glorious durability. The retard has a one-piece aluminum crankshaft carrier, that has ferrous-carbon inserts in a temperament caps for additional strength. The crankshaft is a rarely rigid, forged-steel pattern that uses a micro-polished aspect finish for reduced attrition and augmenting durability. A stiff, cast-aluminum oil vessel provides additional rigidity.

The engine uses high-strength joining rods as good as high-compression cast-aluminum pistons. Through a focus of piston coatings and cylinder sleeve plateau honing, handling attrition is significantly reduced. Plateau honing lowers a attrition turn between a pistons and a cylinders by formulating an ultra well-spoken aspect around a two-stage machining routine (that uses twin harsh processes instead of a some-more compulsory singular honing process). This machining technique also enhances a long-term wear characteristics of a engine. Ion-plated piston rings and low flexibility oil (0W-20) are also used to revoke friction.

i-VTEC® ValveTRAIN System

The 2.4-liter inline 4-cylinder engine facilities a i-VTEC® “intelligent” valve control complement that pairs Variable Valve Timing and Lift Electronic Control (VTEC®) with Variable Timing Control™ (VTC™). The complement delivers softened low-rpm torque, clever high-rpm appetite and superb fuel efficiency.

The 2.4L engine has an aluminum cylinder conduct propitious with twin beyond camshafts, 4 valves per cylinder and a i-VTEC® valvetrain system. High opening camshafts are used that concede for assertive intake valve openings to boost a rate that atmosphere moves into a cylinders. The camshafts are operated by a silent-chain expostulate that helps yield smooth, polished performance. High-strength aluminum rocker arms are used to revoke weight.

The VTEC® member of a i-VTEC® complement adjusts a lift and era of intake valve opening to assistance a engine concurrently furnish clever low-rpm torque and glorious high-rpm power. At low rpm, VTEC® provides valve timing and lift for best cylinder filling. In addition, a timing of a twin intake valves is staggered and their lift is asymmetric— formulating a whirl outcome within a explosion chambers. The outcome is augmenting bake speed with softened explosion stability. As engine rpm builds, VTEC® transitions to a high-lift, long-duration camshaft form for softened high-rpm engine output.

The 2.4L uses a high-performance chronicle of VTEC® that varies a lift and era of a intake valves for limit appetite output. At revoke rpm, a valves follow low lift, brief era camshaft profiles to assistance boost low-end torque. Above 5,000 rpm, a intake valves are operated by high-lift, long-duration cam profiles for limit high-rpm horsepower. When total with VTC™, both camshaft profiles assistance a 2.4L furnish a remarkably extended and well-spoken appetite rope with both glorious torque and horsepower.

Variable Timing Control (VTC)

The 2.4L’s i-VTEC® complement adds Variable Timing Control™ (VTC™) to VTEC® for invariably non-static camshaft phasing opposite a engine’s whole appetite band. As engine rpm builds, a VTC™ actuator (controlled by an engine-control territory that monitors camshaft position, ignition timing, empty oxygen calm and stifle position) advances or retards a intake camshaft, optimizing engine outlay and shortening emissions.

During normal operation, a intake camshaft timing is roughly entirely dense during idle to assistance yield some-more fast waiting while shortening empty emissions (NOx). As rpm increases, a intake camshaft is advanced, opening a intake valves earlier and providing additional valve overlap. This formula in augmenting fuel potency (by shortening pumping losses) and a serve rebate in empty emissions (by formulating a large, inner empty gas re-circulation effect). Also, to beget additional appetite around a rpm range, a intake camshaft is invariably varying a volume of allege or retard, now adjusting to yield additional appetite as compulsory by a driver.

Induction System

The 2.4L engine uses an initiation complement designed for high upsurge and an aggressive, polished sound. The lightweight mixed intake plural has fixed-length intake runners that are tuned in length, hole and figure to yield a mix of low-rpm torque and high-rpm power.

Exhaust System

To revoke tools count and complexity, a empty plural is integrated directly into a cylinder conduct casting. This pattern allows a high-density catalytic converter to be mounted directly to a behind of a cylinder conduct for faster converter light-off. With a cold engine, some-more fast converter light-off after start-up helps revoke hydrocarbons and NOx. Beyond a under-floor catalytic converter, a empty complement passes by a pre-chamber (located underneath a second-row floorboards) and afterwards to a free-flow muffler.

Noise, Vibration and Harshness (NVH) ControL

The 2.4L engine has been designed for class-leading fibre and refinement, with NVH-reducing facilities like a chain-driven balancer territory in a oil pan, ferrous-carbon inserts in a categorical temperament caps for total acerbity and a one-piece crankshaft carrier. The engine also has a wordless sequence cam expostulate and a stiff, cast-aluminum oil pan. Two change shafts serve well-spoken a fundamental quivering ordinarily found with a large-displacement inline 4-cylinder engine layout.
A self-adjusting, silent-type camshaft expostulate sequence and twisted appendage expostulate belt group to assistance revoke NVH. A torque-rod check complement trustworthy to a subframe helps revoke engine rocking and isolates powertrain NVH from a newcomer compartment. The torque-rod engine mountain complement consists of top and revoke torque rods trustworthy to a engine mountain and a front lamp stopper.

6-Speed Manual Transmission

The 2.4L is accessible exclusively with a close-ratio 6-speed primer smoothness with short-throw shifter to yield a ILX motorist with accurate rigging control and glorious change feel. Compared to a 5-speed primer transmission, a 6-speed smoothness allows closer rigging ratio spacing, that enables a engine to work closer to a appetite rise during acceleration for softened performance.

The compress smoothness box is expel of aluminum to revoke weight, and a rarely firm casting helps damp out sound and vibration. Multi-cone synchronizers on First by Fourth gears revoke and well-spoken changeable effort. The close-ratio 6-speed primer smoothness teams with a lightweight, high-capacity clutch, and a specifically designed purchase pedal public that delivers low-effort actuation and has a extended rendezvous rope for larger control and smoother launches.

ILX Hybrid Powertrain

The attainment of a ILX Hybrid outlines a entrance of a first-ever Acura-branded hybrid vehicle. The integrated electric engine in a ILX Hybrid is a chronicle of a Honda fifth-generation integrated electric engine complement that consists of a 1.5-liter i-VTEC® inline 4-cylinder engine connected to a absolute electric motor. A Continuously Variable Transmission (CVT) optimizes a rpm of a engine and engine mixed when operated in involuntary mode. To give a motorist larger control, a smoothness facilities steering-wheel-mounted paddle shifters that concede a preference of 7 bound ratios during primer operation.

The complement uses a gasoline engine as a primary source of appetite and an electric engine provides additional appetite and electricity metamorphosis capability. An modernized lithium-ion (Li-Ion) battery container is used to constraint and store electricity for a electric motor. During acceleration, a engine or a engine and electric engine propel a vehicle. During cruising, a gasoline engine and/or a electric engine can propel a vehicle. During braking, a gasoline engine deactivates and a electric engine acts as generator to feed a battery pack. At a stop, a engine can enter an idle-stop mode to save fuel and revoke emissions, and a engine stays incited off until a stop pedal is released.

Designed to work on Premium Unleaded fuel, a ILX Hybrid engine has a 10.6:1 focus ratio for total appetite and twin hint plugs in any cylinder for rarely fit combustion. The gasoline engine and electric engine mix to furnish limit outlay of 111 horsepower during 5,500 rpm and 127 lb-ft. of torque between 1,000-3,500 rpm.

The ILX Hybrid’s electric engine provides adult to 23 horsepower, and is powered by a lithium-ion battery complement that is some-more powerful, lighter and some-more compress than a Nickel-Metal-Hydride (NiMH) battery used in many other hybrid vehicles. The Powertrain Control Unit (PCU) has been grown to maximize a lithium-ion battery’s appetite and minimize appetite loss. The ILX Hybrid has EPA-estimated* fuel economy of 39/38/38 mpg (city/highway/combined). The ILX Hybrid has a ULEV-2 emissions rating, and is AT-PZEV-rated in states that belong to California Air Resources Board (CARB) emissions standards.

Engine Block, Pistons and Connecting Rods

The engine retard and a inner components are engineered for light weight and low friction. To save weight, a retard is done of expel aluminum and incorporates a thin-sleeve cylinder gimlet construction. Friction shortening measures embody plateau honing, low-friction pistons, low-tensile force piston rings and equivalent cylinder bores to assistance revoke piston parallel loads.

Plateau honing creates an ultra well-spoken aspect to revoke a attrition turn between a pistons and a cylinders. Plateau honing is a 2-stage machining routine that uses twin harsh processes instead of a some-more compulsory singular honing process. This also enhances a long-term wear characteristics of a engine. The outdoor skirts of lightweight aluminum pistons underline a molybdenum coating practical in a singular dot-pattern application. The outcome is reduced altogether attrition as a pistons pierce within a cylinder bores.

Cooling Control Spacer (CCS)

A Cooling Control Spacer (CCS) is positioned in a H2O jackets surrounding a cylinders to assistance revoke piston-to-cylinder friction. Made of a creosote material, a CCS restricts a upsurge of engine coolant around portions of a cylinder bores to say a aloft cylinder temperature. This aloft feverishness causes a cylinder bores to raise slightly, augmenting a piston-to-wall clearway thereby shortening shifting friction. The outcome is about 1-percent boost in fuel efficiency.
 
Cylinder Head and VALVETRAIN

The ILX Hybrid’s 1.5L uses a 2-stage i-VTEC® valvetrain complement that provides singular valve timing to minimize fuel consumption, boost appetite outlay and raise electrical metamorphosis capabilities.

The 1.5L’s singular beyond camshaft (SOHC) cylinder conduct uses a compress sequence expostulate complement and a low-friction VTEC® valvetrain system. It uses a common rocker missile for both a intake and empty rocker arms; fixation all a rocker arms on one missile eliminates a need for a second rocker-arm shaft, so a valve resource can be lighter and some-more compact. To revoke friction, a rocker arms underline tips with drum cam followers.

The compress valvetrain allows for a fascinating slight angle (30 degrees) between a intake and empty valves, that helps emanate compress explosion chambers. To foster a well-balanced and even air/fuel rebate as it enters a engine, a intake ports emanate a whirl outcome in a explosion chambers that optimizes a air/fuel rebate for cleaner, some-more fit combustion.

Since a electric engine (which also acts as an electric generator) is trustworthy directly to a crankshaft of a engine, a engine is designed to yield as tiny insurgency as probable during deceleration to concede a generator to furnish a limit turn of electricity to assign a battery. In a normal engine, a pumping movement of a cylinders provides a assuage volume of resistance, or “engine braking,” during deceleration. The integrated electric engine probably replicates that same feel for a driver.

IGNITION SYSTEM

To safeguard an fit explosion process, consecutive ignition control works in unison with twin hint plugs per cylinder and i-VTEC® system. The ignition complement has 8 ignition coils that are exclusively tranquil according to a energetic engine map program. The advantages of mixed plugs per cylinder are some-more power, rebate fuel expenditure and reduced emissions. The twin retard consecutive control complement is involuntary to respond to engine rpm and bucket conditions. Since a complement has 8 particular ignition coils, it can exclusively manipulate a ignition timing of any iridium-tipped hint plug.

When a air/fuel rebate enters a explosion chamber, a initial hint retard (located nearby a intake port) fires. Shortly thereafter, a second retard fires, accelerating a explosion routine by forcing a fire to generate some-more rapidly. The hint plugs can also light concurrently underneath certain circumstances. This routine formula in some-more finish explosion compared to a singular hint retard system.

ECON MODE

ECON mode helps to urge a ILX Hybrid’s fuel potency by changing and/or tying a operation of certain systems. ECON widens a idle-stop system’s handling window. In addition, a tractable “gain” between a accelerator pedal, throttle-body butterfly, CVT and integrated electric engine changes to serve raise fuel efficiency. The ILX motorist will also find that when journey control is engaged, a automobile takes somewhat longer to strech a set speed. However, as a haven feature, full torque outlay is easy when wide-open stifle is used.

When in ECON Mode, to minimize a activation of a atmosphere conditioning compressors, a threshold for progressing a set cabin feverishness is somewhat augmenting when conditions warrant.

Hybrid Dual-Scroll Air Conditioning Compressor

A dual-scroll hybrid atmosphere conditioning complement reduces a bucket on a gasoline engine by regulating a mixed of engine appetite and an inner electric engine to expostulate twin atmosphere conditioning compressors. These compressors can act exclusively or together as commanded by a cooling needs of a involuntary meridian control complement in a ILX Hybrid.

INTEGRATED ELECTRIC MOTOR System

The integrated electric engine used in a ILX Hybrid is a many absolute to come out of Honda’s hybrid growth program— and a initial ever in a Acura line. As with prior generations, a integrated electric engine consists of an ultra-thin DC brushless electric engine mounted between a gasoline engine and a invariably non-static transmission, and an Intelligent Power Unit (IPU) that stores electric appetite in a compress battery box and controls a upsurge of electricity to and from a electric motor.

Electric Motor
The ILX Hybrid’s light and absolute electric engine is designed to yield an additional 23 horsepower (17.2 kilowatts), providing a supplemental appetite boost and giving a ILX Hybrid a capability to journey on a electric engine alone in certain pushing situations. Mounted between a 1.5L engine and a CVT transmission, a electric engine is an ultra-thin DC brushless pattern and provides a estimable volume of low-end torque to assist acceleration, while also aiding in steady-state cruising and mountain climbing.

The integrated electric engine acts as a generator during deceleration and braking to recapture kinetic appetite that is used to recharge a lithium-ion battery pack. For this fifth era of electric motor, an 8-pole pattern (versus 6-pole design) reduces heat. The new engine operates in a revoke voltage operation (108-172 volts) compared to a prior engine (132-211 volts).

Intelligent Power Unit (IPU)
Power for a integrated electric engine is tranquil by a ILX Hybrid’s Intelligent Power Unit. Located directly behind a behind seatback, a IPU consists of a Power Control Unit (PCU) — or a electric engine authority center, a rechargeable lithium-ion battery module, and an integrated cooling unit. The Power Control Unit (PCU) electronically controls a upsurge of appetite to and from a electric motor.

A bank of lithium-ion cells stores electrical appetite in a battery pack. This bank of 40 particular 3.6-volt batteries stores adult to 144 volts of electrical appetite for a electric motor. The lithium-ion battery record has approximately twice a appetite firmness and about 4 times a outlay firmness of a nickel steel hydride (NiMH) batteries used in many other hybrids. As compared to normal NiMH batteries, with lithium-ion batteries a outlay is augmenting by 33 percent, distance is reduced by 36 percent, weight drops by 29 percent and a work ability of a charging and discharging rates is approximately 3 times higher.

The Integrated Cooling Unit, mounted directly on a battery pack’s outdoor box, helps control a feverishness generated by a consistent upsurge of electricity to and from a battery pack. Interior cabin atmosphere enters a Integrated Cooling Unit around a tiny opening placed on a left outboard behind chair accelerate and is ceaselessly flowed over a battery container and re-circulated.

Regenerative Brake System

To assistance maximize efficiency, a ILX Hybrid recaptures kinetic appetite around a regenerative braking system. The prisoner appetite is stored as electricity in a lithium-ion rechargeable battery pack. The ILX Hybrid uses a electric engine as a generator that can recharge a battery container during braking, solid cruising, peaceful deceleration, or coasting.

The regenerative braking complement cleverly apportions braking appetite between a hydraulic brakes and a electric engine to modify a vehicle’s kinetic appetite into electricity. During braking, a braking vigour sensor sends a vigilance to a Intelligent Power Unit (IPU), that maximizes a turn of regenerative braking. At a same time, a CVT alters a rigging ratio as indispensable to adjust a rpm of a engine to grasp a limit potency for appetite regeneration.

Continuously Variable Transmissiom
The ILX Hybrid facilities as customary a Continually Variable Transmission (CVT)— a initial for Acura. The CVT delivers glorious low-end acceleration matched with loose low-rpm cruising along with offers well-spoken and predicted rigging ratio transitions. By assisting a engine and electric engine work in a many fit range, a CVT provides a fuel potency advantage aloft to that of a compulsory involuntary smoothness with bound ratio gears. It also allows for larger potency during regenerative braking by smoothing deceleration.


The smoothness can be tranquil by a straight-gate console-mounted shifter or around a steering circle paddle shifter complement that works whenever a smoothness is in possibly of a twin involuntary modes. When a paddle shifters are used, a smoothness offers a choice of 7 bound ratios.

Automatic Modes
The smoothness can be operated in twin opposite entirely involuntary modes with a console-mounted straight-gate shifter. The D mode is ideal for many pushing situations, and combines fuel potency with well-spoken operation and manageable appetite when needed. The S mode is for some-more performance-oriented driving, and facilities some-more assertive smoothness mapping to keep engine rpm aloft for larger acceleration and response.

Whether in D or S mode, special smoothness proof programming allows a use of a steering-wheel-mounted paddle shifters. When a motorist operates a steering wheel-mounted paddle shifters while in Drive, a smoothness responds to a driver’s change authority by selecting one of a accessible 7 bound ratios, and afterwards earnings to a normal entirely involuntary Drive mode if serve paddle change inputs are not done within a brief time. This special proof creates it easy for a motorist to authority a discerning downshift but withdrawal a preference of Drive mode.

S Mode
When in S mode, use of a paddle shifters puts a smoothness into full primer mode that stays until another mode of operation is comparison with a console-mounted shifter. The paddle shifters concede a motorist to name among 7 bound rigging ratios. When in primer mode, if a engine redline is reached a ILX will automatically change to a subsequent rigging ratio to equivocate engine damage. It will also change down to an suitable revoke rigging ratio if necessary.

L Mode
When a smoothness is in S mode, concurrently dire and holding a upshift and downshift paddles on a steering circle places a smoothness in L mode. In this mode, a operation of a integrated electric engine is altered to boost a assign rate of a lithium-ion battery.

Common Powertrain Features

Drive-by-Wire Throttle ControL

An electronic Drive-by-Wire™ stifle control complement helps raise a pushing impression of all ILX models. With intelligent wiring joining a stifle pedal to a stifle physique trustworthy to a estuary of a intake manifold, a engine response can be optimized to fit a pushing conditions and to softened compare a driver’s expectations. A DC engine controls a stifle physique opening position in a intake tract. To settle a stream pushing conditions, a complement monitors equipment such as pedal position, stifle position, automobile speed, engine speed and engine vacuum. This information is afterwards used to conclude a stifle control sensitivity.

Programmed Fuel Injection (PGM-FI)

All ILX engines underline Programmed Fuel Injection (PGM-FI) that uses an array of sensors to constantly guard a series of vicious handling variables, including stifle position, intake atmosphere temperature, H2O temperature, ambient atmosphere vigour (altitude), atmosphere flow, along with a position of a crankshaft and camshaft(s). Special multi-hole fuel injectors mounted in a revoke intake plural mist directly toward a intake ports. The multi-hole injector pattern means that fuel drop distance is reduced for softened fuel atomization, ensuing in softened cold continue start-up, softened fuel potency and aloft horsepower.

Direct Ignition System and Detonation Knock ControL

A clever ignition hint is vicious to urge appetite and revoke emissions. All ILX engines underline a approach ignition complement that uses particular curl units positioned directly above any double-tipped electrode hint plug. The Powertrain Control Module (PCM) ceaselessly monitors several engine parameters to settle best hint timing formed on specific pushing conditions. Additionally, a block-mounted acoustic eruption (knock) sensor sends information with any crankshaft rotation, so that a engine can investigate eruption frequencies with high precision. These signals are sent to a PCM, that afterwards controls ignition timing as indispensable to assistance forestall damage.

Maintenance Minder System

All ILX models underline a Maintenance Minder™ complement that automatically monitors a vehicle’s handling condition. The motorist is alerted around a summary on a Multi-Information Display (MID) located between a tachometer and speedometer when upkeep is required. The complement helps liberate nonessential use stops, while ensuring that a automobile is scrupulously maintained.

The Maintenance Minder™ complement monitors handling conditions such as coolant and oil along with engine speed, and afterwards determines a correct use intervals. The Multi-Information Display (MID) shows a remaining commission of engine oil life, and a percentage-based countdown to a subsequent use is displayed when a automobile is within 15 percent of a finish of a use interval. The form of use compulsory is shown in an alphanumeric code, and if a use is missed, a MID indicates a coercion by display past-due mileage.
The complement can be reset manually by a owner, and monitors all normal use tools and systems, including oil and filter, air-cleaner, tire rotation, coolant, hint plugs, stop pads and more. Maintenance alerts are presented on a instrument cluster when a ignition is initial incited on, and not while driving.

BATTERY MANAGEMENT SYSTEM (BMS)

The 2013 ILX uses Acura’s new Battery Management System (BMS) that is designed to revoke a possibility of a passed battery and boost a altogether use life of a battery.

Should an ILX owners incidentally leave on a headlights or not tighten a doorway (thus causing an interior light to sojourn on), after a set duration of time a BMS will automatically cancel appetite smoothness to forestall a battery from discharging. As a outcome of a liberate insurance afforded by a BMS, a battery should have adequate haven ability left to start a engine.
