DETROIT (Wednesday, Jun 24, 2015) – The 2016 Chevrolet Cruze is powered by General Motors’ new, tellurian family of Ecotec small-displacement engines, featuring a modular pattern that is easier to build and non-static to tellurian markets, while charity business segment-challenging efficiency, excellence and durability.

In North America, a Cruze is charity with a new Ecotec 1.4L turbocharged engine that facilities instruction injection to assistance offer a GM-estimated 5.9 L/100km highway fuel potency with an accessible six-speed involuntary transmission. Standard stop/start record contributes to potency in stop-and-go driving.

The new 1.4L turbo is SAE-certified during 113 kW (153 hp) and 240 Nm of torque (177 lb-ft), regulating unchanging unleaded fuel. It will be charity in additional markets, along with a 1.5L naturally aspirated variant, rated during an estimated during 84 kW (113 hp) and 146 Nm of torque (108 lb-ft). The 1.5L will be matched with a five-speed primer transmission.

“The new Ecotec family is a globally designed and made engine designed to offer class-leading performance, potency and excellence in a far-reaching accumulation of applications around a world,” pronounced Dan Nicholson, vice-president, GM Global Powertrain. “Each various is designed for a specific focus or internal market, though all share design, opening and excellence traits that make a new pattern one of a many non-static in a industry.”

The new Ecotec 1.4L turbo is matched with a customary six-speed primer or accessible with GM’s new Hydra-Matic 6T35 six-speed involuntary transmission, that offers a strength of a incomparable 6T40 delivery in a smaller, lighter package that enhances potency in a compress Cruze.

Chevrolet will supplement a new purify diesel engine to a lineup in 2017, featuring a B20-capable 1.6L diesel already proven in Europe and other tellurian markets.

“The stream Cruze diesel has garnered a constant following among business seeking strong, purify and fit diesel,” pronounced Nicholson. “The subsequent Cruze diesel will take those attributes to a subsequent turn with a really latest technology, charity what we pattern will be a premier small-car diesel package in North America. It affirms GM’s joining to offer diesel engines as an choice thrust choice for cars in North America and privately targets a German prevalence in a segment.”

More information about a subsequent Cruze diesel will be accessible closer to a start of production.

Clean-sheet design

The new Ecotec small-displacement engine family featured in a Cruze represents a clean-sheet pattern and engineering process, leveraging a different knowledge of GM’s tellurian resources. Modularity in tools – such as four-cylinder and three-cylinder blocks – that share gimlet spacing, gimlet diameter, liners and other dimensions, reduces complexity and enhances value.

The new engines underline an aluminum cylinder retard and head, that helps revoke a Cruze’s altogether mass to raise opening and efficiency. They also underline an integrated aluminum cylinder head/exhaust manifold, that serve reduces weight – an charge that contributes to increasing automobile potency and a some-more auspicious front-to-rear weight balance, for a some-more manageable pushing experience.

Additional engine features:

  • Aluminum bedplate on a engine retard enhances strength and refinement
  • Variable-flow oil siphon enhances efficiency
  • Piston-cooling oil jets minister to optimal performance, potency and refinement
  • Dual-overhead-cam cylinder conduct with integrated empty plural saves weight to raise opening and efficiency
  • Premium inverted-tooth camshaft expostulate sequence contributes to segment-challenging levels of excellence and low noise.

Computer make-believe and displaying were instrumental in building a new engine family. GM’s engineers during powertrain centres around a creation were means to pattern and exam tools probably and immediately share a formula with their colleagues.

In further to conceptualizing a engines’ basis components electronically, friction, temperature, emissions, potency and other opening attributes were modeled and unnatural mixed times to make a many of opening before a initial earthy components were produced. Modeling also helped cylinder retard pattern and other components with constructional and acoustic considerations.

“By doing a infancy of a growth with math data, a time to design, countenance and move to marketplace an all-new engine family was severely reduced,” pronounced Tom Sutter, Ecotec tellurian arch engineer.

The engines’ calibration and opening characteristics change among markets, though all variants were tested underneath GM’s despotic fast regardless of their application. It’s one of a toughest set of standards in a attention and enclosed a battery of round-the-clock opening and continuance trials such as:

  • Running exam engines invariably for some-more than 2,000 hours during 5,200 rpm – a homogeneous of 12 true weeks during wide-open-throttle
  • Cycling engines for 400 true hours (more than 16 days) between rise horsepower and rise torque rpm levels – a torturous exam that pushes rotating tools such as a crankshaft and joining rods to their limits
  • Running engines on lean mount – a hydraulically actuated dynamometer that tilts a engine during operation to copy pushing on high grades or high-speed cornering. That helps safeguard a oiling complement maintains full vigour during impassioned pushing conditions
  • Cold- and heat-soak tests that safeguard a engine will start and work routinely in temperatures as low as -40 degrees C (-40 F) and as high as 104 degrees C (219 F)
  • Testing in an acoustic laboratory to magnitude engine sound frequency, ensuring production-spec components work harmoniously to furnish low quivering and a appreciative engine sound.

Lightweight and durable foundation

A lightweight, high-pressure die-cast aluminum retard is a engines’ foundation, matched with an aluminum bedplate that enhances strength and helps revoke vibration. The high-pressure casting process produces a some-more dimensionally accurate retard that requires fewer machining operations than compulsory sand-cast blocks.

For constructional stiffness, a retard has cast-in-place iron cylinder liners. The bedplate bulkheads also enclose cast-in, nodular iron inserts for localized constructional stiffness. A die-cast aluminum oil vessel contributes additional constructional strength.

Each engine facilities 74 mm (2.9-inch) cylinder bores and partially prolonged piston cadence lengths that minister to their clever torque. The 1.4L has an 81.3 mm (3.2-inch) cadence and a 1.5L chronicle has an 86.6mm (3.4-inch) stroke.

Bay-to-bay breathing, that enhances opening by reduced windage in a crankcase, is enabled by holes expel in a tip of a bulkheads and by passages expel where a retard and bedplate meet. Cast passages for oil and blow-by government and a 4 mm wall density mix to revoke a altogether weight of a retard assembly, enhancing automobile opening and efficiency.

Additional engine features:

  • A durable steel crankshaft is used with a Ecotec 1.4L turbo and Ecotec 1.5L for strength and reduced engine vibration
  • Powder-metal steel joining rods and hypereutectic-alloy aluminum pistons that are tough and minister to quietness. They are used with low-tension rings that revoke friction, that contributes to incomparable efficiency.
  • A variable-flow oiling complement helps maximize fuel efficiency, contributing to GM’s estimated 5.9 L/100km highway. The crankshaft-driven oil siphon that matches a oil supply to a engine load, changing a ability formed on a engine’s direct for oil – expelling appetite squandered to siphon oil that is not compulsory for correct engine operation
  • Piston-cooling oil jets minimize piston temperatures – assisting to optimize performance, refinement, potency and emissions.

The cylinder conduct has a water-cooled empty plural integrated within a aluminum casting. Its single-piece pattern promotes quicker engine warm-up, that contributes to improved emissions performance. It also enhances continuance by expelling a need for gasket sealing around a empty ports, as good as charity under-hood wrapping advantages.

Dual beyond camshafts, handling 4 valves per cylinder with low-friction, hydraulic drum finger followers, are vale in sections to save weight, and are driven by a timing sequence with involuntary hydraulic tensioning. Aluminum cam phasers capacitate non-static timing for a opening and shutting of a estuary and empty valves, creation a many of fuel expenditure and opening underneath a far-reaching accumulation of engine bucket conditions.

Refinement details

Along with opening and efficiency, a 2016 Cruze’s new Ecotec engines broach glorious refinement, with low quivering and sound levels.

Engineers targeted each aspect of a architecture, reciprocating components, fuel complement and engine government functions in a query for world-class fibre and quietness. It all starts with a all-aluminum architecture, that is acoustically designed to revoke airborne and structure-borne handling noise.  

Additional facilities that minister to a engines’ excellence include:

  • The camshaft drive-chain is optimized for low sound levels by an inverted-tooth design. The whole sequence architecture, including a tensioning, hang and guides, is designed for reduced altogether sound deviation and a rejecting of any viewed aberrant sounds
  • The formation of a hammered steel sump during a bottom of a aluminum oil vessel also reduces noise
  • The front-end appendage expostulate facilities an major alternator coupler to mislay a outcome of crankshaft oscillations. In further to excellence benefits, it also reduces tragedy to revoke attrition levels and urge efficiency
  • Acoustically optimized covers for a tip and front of a engine
  • Crankshaft siege with iron categorical temperament inserts.

Manufacturing

The Ecotec 1.4L will be fabricated in Flint, Mich. with locally and globally sourced parts. GM’s engine trickery in Toluca, Mexico will also build a 1.4L, as good as a Ecotec 1.5L.

New 6T35 six-speed involuntary transmission

The new Hydra-Matic 6T35 six-speed involuntary delivery charity with a Cruze’s new 1.4L turbo engine expands GM’s multispeed delivery family for cross powertrain systems.

It is a higher-capacity chronicle of a stream 6T30 transmission, charity allied torque ability of a incomparable 6T40, though in a smaller, 11-kg (24 lbs) lighter package contributing to a Cruze’s reduced altogether weight and enhances a front-to-rear weight balance.

Shared traits between GM’s six-speed involuntary transmissions also revoke complexity, distance and mass, including clutch-to-clutch operation that enables a six-speed to be finished into approximately a same space of a four-speed automatic.

A far-reaching ratio widespread enables sprightly acceleration from a stop, while a overdriven sixth rigging – it “turns” slower than engine speed – keeps a engine speed reduce on a highway, shortening engine attrition losses, optimizing potency and contributing to a quieter ride.

The 6T35 also facilities Gen 3 upgrades implemented to raise efficiency. The pump, for example, has been changed off-axis, that allows improved sealing of a torque converter, shortening siphon upsurge final to raise fuel efficiency. Additionally, a siphon is now a binary vane-type, that allows reduce appetite expenditure during times of reduce upsurge final and during aloft engine speeds. An accumulator is combined to a transmission, as well, to accommodate a stop/start system.

The 6T35 will be built during GM’s delivery trickery in Toledo, Ohio.

Manual transmissions

Cruze models versed with a 1.4L turbocharged engine are charity with a M32-code six-speed primer transmission, a high-capacity gearbox for cross configurations. A wide, 7:1 altogether ratio balances acceleration and efficiency.

The M32 has a reward three-shaft pattern with synchronizers for all gears, including reverse. First and second gears underline triple-cone synchronizers and double-cone synchronizers are used on third and fourth gears. An outmost change complement enhances a high-quality feel of a delivery with short, accurate shifts, as good as quivering absorber.

Models versed with a 1.5L engine are charity with a five-speed primer delivery – a compact, lightweight delivery featuring a two-shaft pattern and reward facilities such as full synchronization on a brazen gears and semi-synchronized rendezvous for reverse. Hydraulic purchase actuation and a cable-type changeable complement capacitate light, easy and well-spoken shifting.
