We’ve compiled a comprehensive guide of General Motors engines used around the world. The MHI turbos are sized to provide quick torque response, and are mounted very close to the cylinders, thanks to cylinder heads that incorporate the exhaust manifolds in the head.
Officials said that by 2017, more than 2.5 million new Ecotec engines will be assembled annually at five different plants worldwide, and those units will be used in many of the company’s highest-volume small cars and crossovers throughout five brands and 27 models. Horsepower will range from 75 up to 165 with peak torque output ranging from 70 lb-ft up to 184 lb-ft. All are designed to meet stricter emissions and fuel economy requirements around the world. We're told this engine weighs 216 pounds, ready for installation. Today GM provided some additional background on the all-new family of three- and four-cylinder gasoline engines that has been undergoing development around the world for the last three years. Today, there are only two families of V8 engines in production for road vehicles: the Generation IV small-block and its Generation V small-block derivative. 1,118 cc (1.1 L; 68.2 cu in) I3 PFI 86.6 mm (3.41 in) stroke, 1,399 cc (1.4 L; 85.4 cu in) I4 DI DCVCP turbo 81.3 mm (3.20 in) stroke and. The MHI turbos are sized to provide quick torque response, and are mounted very close to the cylinders, thanks to cylinder heads that incorporate the exhaust manifolds in the head. Bay-to-bay breathing to reduce windage in the crankcase is enabled through holes cast in the top of the bulkheads and through passages cast where the block and bedplate meet. Additionally, the 1.0-liter variant features a balance shaft mounted inside the oil pan to quell the unique vibration characteristics of a 3-cylinder arrangement.
The first application for the new Ecotec family will be a 1.0-liter turbo 3-cylinder model for the Opel Adam in Europe followed by 1.4-liter turbo and 1.5-liter N/A 4-cylinder engines in the next-generation Chevy Cruze in China. The cast-aluminum oil pan is strengthened with a steel sump that also contributes to noise reduction.

DETROIT -- General Motors is creating a family of more fuel efficient small engines that it says will be quieter and more refined than those found in some rival models. Compression ratio is 12.5:1 and the engine can run on regular unleaded grade gasoline. A partnership of GM's Research and Development Division and their Winton Engine Corporation delivered their first diesel engines suitable for mobile use starting in 1934. All new Ecotec engines are calibrated to run on regular unleaded gas, stated GM, including the high-output turbo variants. Mike Magda is a veteran automotive writer with credits in publications such as Racecar Engineering, Hot Rod, Engine Technology International, Motor Trend, Automobile, Automotive Testing Technology and Professional Motorsport World.
Such commonality helps reduce engine family engineering and manufacturing complexity and supplier proliferation, while unique technology and content (like port or direct injection, turbocharging or natural aspiration, and varying degrees of exhaust after-treatment) tailors various engines to meet specific regional needs. Base model engines will be port-fuel injected (PFI). They're using OnStar to get info on where people charge....

Turbocharged engines will run at 10:1 on regular unleaded fuel.
By the 1970s, GM began to see problems with their approach. • For future polar vortices, EcoTec engines should put heat in the cockpit faster than ever, thanks to an electronically controlled thermostat, a clutched water pump that moves no coolant during a cold start, and a water-jacketed exhaust manifold. To hit their lofty noise and vibration targets, the direct injection fuel rail mounts to the cylinder head and valve cover via bushings that isolate that loud ticking noise the injector pintles make. The 4-cylinder offerings include a 1.4-liter (81mm/3.2-inch stroke) and 1.5-liter (86.6mm/3.4-inch). All turbocharged variants will provide 90 percent of their max torque between 1500 and 5000 rpm, with peak power arriving between 5600 and 6000 rpm. © 2017 Power Automedia. The 1.5-liter model will be offered in DI and DI turbo versions. To achieve this, it features lightweight design and advanced technologies like gasoline direct injection, turbocharging, variable length intake manifold and alternative fuel compatibility. The 1.0-liter 3-cylinder gets PFI, DI turbo and LPG versions while the 1.1-liter will be offered only in PFI. The LYX is a direct-injection cast aluminum DOHC 1.5 L turbocharged SGE variant, with a 74 mm × 86.6 mm (2.91 in × 3.41 in) bore and stroke for a total capacity of 1,490 cc (1.5 L).

The system uses a comparatively small, low-inertia water-cooled, single-stage, single-scroll turbocharger that’s mated with an intercooler and pressure-activated wastegate. The engines will meet SULEV standards in the U.S. and Euro 6 standards in Europe. Compression ratio is 10.6:1 and the engine can run on regular unleaded grade gasoline.
Unfortunately, this is how we pay the bills and our authors. Fuel consumption is at the leading edge of the competitive set, with the new 1.4-liter turbo performing 5 percent more efficiently than the current 1.4-liter turbo. Compression ratio is 10.0:1 and the engine can run on regular grade gasoline.
Maximum engine speed is 6000 rpm. Some 270 engines were run through endurance tests that four weeks of wide-open-throttle operation. This is GM's bread-and-butter ECOTEC engine and the first non-boosted ECOTEC to sport direct injection, expect it to be phased out in favor of the 2.5-liter in the coming 2-3 years. The diameter of the turbine wheel is only 35 mm, while the low-hiss compressor measures only 40 mm in diameter to help the engine deliver 90 percent of maximum torque at only 1,500 rpm for the 1.4L variant. It will get a choice of 1.5-liter naturally aspirated or 1.4-liter turbo, and although the presenters were at pains to dissuade us from assuming the same engines will be offered in the North American Cruze, it's hard to imagine they wouldn't be.
