For the Fiat TwinAir engine also refered to as Small Gasoline Engine, see Fiat TwinAir engine.Family of small displacement three and four cylinder gasoline engines designed by GM.Motor vehicle engineThe GM Small Gasoline Engine (SGE) is a family of small-displacement three- and four-cylinder gasoline engines ranging from 1.0 L to 1.5 L, developed by Adam Opel AG, Shanghai Automotive Industry Corporation (SAIC), MG Motor (MG), Shanghai GM (SGM) and the Pan-Asia Technical Automotive Center (PATAC).[1]The new global family is designed to improve fuel economy, performance, and emissions, reduce noise and vibrations. To achieve this, it features lightweight design and advanced technologies like gasoline direct injection, turbocharging, variable length intake manifold and alternative fuel compatibility. It utilizes modular approach with interchangeable components that can be suited to specific application.The initial engine variants include999\u00a0cc (1.0\u00a0L; 61.0\u00a0cu\u00a0in) I3 DI DCVCP turbo 77.4\u00a0mm (3.05\u00a0in) stroke,1,118\u00a0cc (1.1\u00a0L; 68.2\u00a0cu\u00a0in) I3 PFI 86.6\u00a0mm (3.41\u00a0in) stroke,1,399\u00a0cc (1.4\u00a0L; 85.4\u00a0cu\u00a0in) I4 DI DCVCP turbo 81.3\u00a0mm (3.20\u00a0in) stroke and1,490\u00a0cc (1.5\u00a0L; 90.9\u00a0cu\u00a0in) I4 PFI 86.6\u00a0mm (3.41\u00a0in) stroke. All are derived from just two blocks (three and four cylinder) sharing a common 74\u00a0mm (2.91\u00a0in) bore with 81\u00a0mm (3.19\u00a0in) bore spacing. Mitsubishi Heavy Industries provides one-stage single-scroll turbocharger.[2]To aid with NVH (Noise, vibration, and harshness) levels 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. GM claims that the 1.0-liter turbo is 25 percent (3 dBA) quieter than the Ford Fiesta’s 1.0-liter turbo, and the 1.4-liter is up to 50 percent (6 dBA) quieter than the VW\/Audi 1.4-liter turbo. Other silencing measures include a bed-plate cylinder block that increases stiffness, a stiffened aluminum front cam cover. Three-cylinder variants get a counter-rotating (engine-speed) balance shaft that is integrated with the oil pump and located inside the two-piece aluminum oil pan to prevent radiated noise. GM claims the EcoTec triple will idle more smoothly than Ford’s three-cylinder, which does not use a shaft.[2]All turbocharged variants will provide 90 percent of their max torque between 1500 and 5000\u00a0rpm, with peak power arriving between 5600 and 6000\u00a0rpm. 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.[2]To reduce mass, the engines are compact in all directions, made almost entirely of aluminum, and feature composite intake manifolds. This removes 44 pounds (20\u00a0kg) from the existing 1.4-liter turbo in the Cruze and makes it 8 pounds (4\u00a0kg) lighter than the 1.4-liter VW turbo. GM says this engine weighs 216 pounds (98\u00a0kg), ready for installation.[2]The engines will debut in the 2014 Opel Adam[3] and will be produced in Szentgotth\u00e1rd, Hungary[4][5] and GM’s Flint Engine plant.[6] The new engine family will spread to other brands and markets by the end of the decade and will replace three separate engine families (S-TEC, Family 0, and Family 1).The engine is used in:The assembly lines for North American facilities were manufactured by Hirata Corporation at their powertrain facility in Kumamoto, Japan.Table of ContentsNon-Opel Variants[edit]1.4[edit]LV7[edit]LE2[edit]1.5[edit]L3A[edit]LFV[edit]LYX[edit]LSD[edit]Opel Variants[edit]See also[edit]References[edit]External links[edit]Non-Opel Variants[edit]1.4[edit]LV7[edit]The LV7 is the multi-point fuel injection 1.4L naturally aspirated variant of the SGE engine, with a 74\u00a0mm \u00d7\u00a081.3\u00a0mm (2.91\u00a0in \u00d7\u00a03.20\u00a0in) bore and stroke for a total capacity of 1,399\u00a0cc (1.4\u00a0L).
