Engine Architecture and Features

Turbocharged i-VTEC 2.0-Liter In-Line 4 Cylinder
Assembled in Honda’s Anna, Ohio engine plant, a Civic Type R’s DOHC 2.0-liter engine is a many comprehensive engine ever offering in a prolongation Honda in America. With 33-percent incomparable banishment than a other turbocharged engines offering in a Civic family, a Type R powerplant is engineered to broach an boost of 101 horsepower and 103 lb.-ft. of torque when compared to a subsequent many comprehensive Civic, a Civic Si Coupe and Civic Si Sedan. With approach injection, low-inertia high-flow mono corkscrew turbo element with electrical waste-gate and a limit of 23.2 psi of turbocharger boost, a Type R powerplant develops a horsepower and torque of a distant larger, routinely aspirated engine.

The turbocharged Type R 2.0-liter engine is designed to work on reward unleaded fuel and is rated during 306 horsepower during 6,500 rpm and 295 lb.-ft. of torque between 2,500 and 4,500 rpm. The Civic Type R is rated by a EPA during 22/28/25 mpg1 city/highway/combined.

Cylinder Block and Crankshaft
The Civic Type R’s 2.0-liter inline 4-cylinder engine has a lightweight die-cast aluminum retard with reinforced categorical temperament caps to minimize weight. Centrifugally expel iron cylinder sleeves yield long-lasting durability. In a seductiveness of engine responsiveness, a specifically developed, super lightweight forged-steel crankshaft is used exclusively in a Civic Type R. Each biography on a crankshaft is micropolished to revoke handling friction.

Pistons and Connecting Rods 
The 2.0-liter engine’s pistons have “cavity-shaped” crowns that assistance say fast explosion and minister to softened efficiency. The lightweight pistons have a delicately optimized dress pattern to minimize reciprocating weight, that minimizes quivering and increases handling efficiency. The pistons are cooled by oil jets destined during a underside of any piston climax and underline an middle “cooling gallery” like Honda Formula 1 engines that is designed to revoke feverishness in a piston ring area. Ion-plated piston rings assistance revoke attrition for incomparable handling efficiency. Special super lightweight, high-strength steel joining rods are heat-forged in one square and afterwards “crack separated” to emanate a lighter and stronger rod with an optimally propitious temperament cap.

Cylinder Head and i-VTEC® Valvetrain
The direct-injected Civic Type R 4-cylinder turbocharged engine has a lightweight pressure-cast aluminum amalgamate DOHC cylinder head. With empty ports expel directly into a cylinder head, a need for a normal apart empty plural is eliminated, shortening engine weight and simplifying a assembly. The plural is glass cooled to assistance keep feverishness in check.

 alt=

A low-friction, wordless sequence drives twin beyond cams and 4 valves per cylinder. The cam expostulate is upkeep giveaway for a life of a engine. To serve revoke weight, thin-wall vale camshafts are used.

To advantage fuel efficiency, emissions and power, a turbo engine utilizes sodium-filled empty valves. A vale cover within a valve contains sodium that is cooled by a empty pier cooling jacket. Since a cover is tighten to a valve head, a sodium helps to cold a whole valve; and given a valve is internally cooled, it doesn’t need a enriched fuel reduction that is generally used in turbo engines to assistance cold empty valves. The following leaner reduction reduces emissions, increases fuel potency and increases power.

The Civic Type R’s 2.0-liter DOHC 16-valve i-VTEC® engine uses an modernized valve control element to mix high energy outlay with high fuel potency and low emissions. The element combines intake and empty VTC (Variable Valve Timing Control), that invariably adjusts a intake and empty camshaft phase, with Variable Valve Timing and Lift Electronic Control (VTEC), that changes valve lift, timing and generation of a empty valves.

The “intelligent” apportionment of a element is a ability to invariably change a timing of a intake and empty camshafts regulating non-static valve timing control (VTC). This helps boost energy and also provides a smoother idle (allowing idle speed to be reduced). The cam timing is sundry formed on submit from sensors that guard rpm, timing, stifle opening, cam position and empty air-fuel ratio. The outcome is increasing fuel potency and revoke emissions.

The cylinder conduct includes tiny M12 sparkplugs, down from a some-more common M14, to save space and weight. The conduct also includes direct-injection multi-hole fuel injectors with a small-diameter bore. Higher-pressure approach injection optimizes fuel atomization, permitting for some-more fit combustion. To yield a high-tumble intake assign that serve enhances explosion efficiency, both a intake pier and piston climax have special designs.

Direct Injection System
The direct-injection element enables increasing torque opposite a engine’s full handling operation along with aloft fuel potency and low emissions. Multi-hole injectors broach fuel directly into any cylinder (not to a intake port, as in compulsory pier fuel injection designs), permitting for some-more fit combustion. The element facilities a compact, high-pressure, direct-injection siphon that allows both high fuel upsurge and tapping suppression, while non-static vigour control optimizes injector operation.

High-Flow Exhaust System
The Civic Type R facilities a specifically designed high-flow empty element with a singular triple-outlet pattern centered in a back of a car. The core opening is a pivotal cause in a sound of a empty note in a Type R interior. The element is engineered to offer a stirring empty note underneath acceleration, joined with still cruising during low energy settings.

Low Inertia Mono Scroll Turbo System with Electric Wastegate
The turbocharged Civic Type R engine employs a small-diameter, low-mass turbine for limit responsiveness. The mono corkscrew housing pattern helps a turbo build boost even during comparatively tiny stifle openings and low rpm. The electrically actuated wastegate allows boost vigour to be precisely controlled. The Type R’s limit boost pressure, during 22.8 psi, is adult from a 16.5 psi found in 1.5-liter Civic turbo models and 20.3 psi in a Civic Si Coupe and Civic Si Sedan.

A vast low-restriction intercooler is positioned low in a front of a automobile where it receives unrestricted airflow when a automobile is in motion. Intake atmosphere travels from a atmosphere filter, to a turbo compressor, on to a intercooler, afterwards to a engine’s intake ports. The intercooler helps revoke a feverishness of atmosphere entering a engine, creation it denser for incomparable performance. To revoke weight, a turbo element is plumbed with rigid, lightweight creosote combination estuary pipes to lift intake atmosphere to and from a intercooler.  

Friction Reducing Technology
The Civic Type R engine creates use of a operation of friction-reducing technologies designed to urge engine efficiency:

  • The outdoor skirts of a lightweight aluminum pistons underline a low-friction molybdenum cloaking practical in a dot pattern 
  • Plateau honing of a cylinder walls removes little high points to serve revoke attrition while improving a long-term wear characteristics of a engine.  
  • Low flexibility oil (0W-20)  
  • Other contributors to altogether handling potency are a special 2-stage oil siphon use valve, low-friction oil seals, special low-drag piston ring design, low-friction cam sequence and a lightweight crankshaft. 

Drive-by-Wire Throttle System
The Civic Type R’s Drive-by-Wire stifle element replaces a compulsory stifle wire with intelligent wiring that “connect” a accelerator pedal to a stifle valve inside a stifle body. The outcome is reduction under-hood confusion and revoke weight, as good as quicker and some-more accurate stifle actuation. Plus, a specifically involuntary “gain” rate between a stifle pedal and engine offers softened drivability and optimized engine response to fit specific pushing conditions.

100,000+/- Mile Tune-up Intervals
The Civic Type R’s powerplant requires no scheduled upkeep for 100,000+/- miles or more, other than periodic inspections and normal liquid and filter replacements. The initial tune-up includes H2O siphon inspection, valve adjustment, and a designation of new hint plugs.

Maintenance Minder™ System
To discharge nonessential use stops while ensuring that a automobile is scrupulously maintained, a Civic Type R has a Maintenance Minder™ element that ceaselessly monitors a vehicle’s handling condition. When upkeep is required, a motorist is alerted around a summary on a Multi-Information Display (MID) on a Driver Information Interface (DII). (See a Interior territory for some-more information.)

The Maintenance Minder™ element monitors handling conditions such as oil and coolant feverishness along with engine speed to establish a correct use intervals. Depending on handling conditions, oil change intervals can be extended to a limit of 10,000 miles, potentially provident a owners substantial responsibility and nuisance over a life of a vehicle. The owner-resettable element monitors all normal use tools and systems, including oil and filter, tire rotation, air-cleaner, hint plugs, coolant, stop pads and more. To revoke a intensity for motorist distraction, upkeep alerts are presented usually when a ignition is initial incited on, not while driving.

6-Speed Manual Transmission
For Honda’s ultimate opening car, only one smoothness is available, an ultra-quick-shifting 6-speed primer smoothness (6MT). Topped with a plain aluminum change knob, a section offers well-spoken and accurate change feel with crisply tangible change gates. An updated chronicle of a smoothness used in a previous-generation Civic Type R (not accessible in America), a 2017 Civic Type R smoothness has a operation of refinements and improvements. To keep feverishness in check, a smoothness incorporates a cooling fin box design, along with a new liquid-cooled oil cooler.

 alt=

The 6-speed smoothness has been engineered to broach state-of-the-art opening and change action, with really low middle friction, parsimonious middle tolerances and well-spoken synchronizers. A lightweight single-mass flywheel is used to whet engine response by minimizing purchase inertia. Compared to other Civic 6-speeds, a smoothness has a some-more firm extraneous case, high-strength temperament system, high-strength gears, and incomparable torque capacity. A constant-mesh scrolled retreat rigging resource reduces sound when retreat is selected. A retreat lockout underline prevents a smoothness from incidentally being shifted into retreat while a automobile is relocating forward.

Automatic Rev Matching
For optimally matched engine rpm during upshifts and downshifts, a Civic Type R facilities customary involuntary rev matching. When this selectable underline is enabled, a Drive-by-Wire stifle element automatically adjusts a engine rpm during rigging changes to compare a subsequent rigging a motorist selects. Automatic rev relating creates a Type R easier to expostulate by minimizing driveline startle during upshifts and downshifts.

The Civic Type R’s involuntary rev relating has dual operational profiles: in COMFORT or SPORT modes, a rev compare element uses a seamless profile, designed to give a Type R a smooth, gentle change feel; in +R mode, a element switches to a some-more aggressive, quick-revving form designed to element a faster paced changeable of opening driving. The rev compare element can be infirm regulating a Type R’s customizable settings menu.

Helical Limited-Slip Differential
Powerful opening cars with compulsory “open” differentials can humour from extreme circle spin, quite from a middle expostulate circle when cornering. The Civic Type R’s helical-type limited-slip differential (LSD) helps protection that extreme circle spin doesn’t happen, by putting some-more of a engine’s energy effectively to a pavement. Under power, a limited-slip differential works to equate a speed of a dual expostulate wheels. The element never thatch a speed of a dual expostulate wheels together as would a locking differential, though instead allows opposite circle speeds to accommodate a longer stretch a outdoor circle contingency transport when cornering. The LSD allows a Type R to accelerate harder on surfaces with disproportionate traction, to beget reduced circle spin when exiting corners, and to raise a vehicle’s responsiveness to stifle inputs in corners. The tenure “helical” describes a approach a differential’s rigging teeth are cut – that is during an angle to a gear’s shaft. Helical gears are quieter in operation and can broadcast incomparable torque than straight-cut (or spur) gears.
