The GM Ecotec engine, also known by its codename L850, is a family of all-aluminium inline-four engines, displacing between 1.2 and 2.5 litres. Confusingly, the Ecotec name was also applied to both the Buick V6 Engine when used in Holden Vehicles, as well as the final DOHC derivatives of the previous GM Family II engine; the architecture was substantially re-engineered for this new Ecotec application produced since 2000. This engine family replaced the GM Family II engine, the GM 122 engine, the Saab H engine, and the Quad 4 engine. It is manufactured in multiple locations, to include Spring Hill Manufacturing, in Spring Hill, Tennessee, with engine blocks and cylinder heads cast at Saginaw Metal Casting Operations in Saginaw, Michigan.
The General Motors LS-based small-block engines are a family of V8 and V6 engines designed and manufactured by American automotive company General Motors. First introduced in 1997, the family is a continuation of the earlier first- and second-generation Chevrolet small-block engine, of which over 100 million have been produced altogether, and is also considered to be one of the most popular V8 engines ever. Spanning three generations, a new, sixth generation is expected to enter production soon. Various small-block V8s were and still are available as crate engines.
The General Motors 60° V6 engine family is a series of 60° V6 engines produced for both longitudinal and transverse applications. All of these engines are 12-valve cam-in-block or overhead valve engines, except for the LQ1 which uses 24 valves driven by dual overhead cams. These engines vary in displacement between 2.8 and 3.4 litres and have a cast-iron block and either cast-iron or aluminum heads. Production of these engines began in 1980 and ended in 2005 in the U.S., with production continued in China until 2010. This engine family was the basis for the GM High Value engine family. These engines have also been referred to as the X engines as they were first used in the X-body cars.
The GM High Feature engine is a family of modern DOHC V6 engines produced by General Motors. The series was introduced in 2004 with the Cadillac CTS and the Holden Commodore (VZ).
The Oldsmobile V8, also referred to as the Rocket, is a series of engines that was produced by Oldsmobile from 1949 until 1990. The Rocket, along with the 1949 Cadillac V8, were the first post-war OHV crossflow cylinder head V8 engines produced by General Motors. Like all other GM divisions, Olds continued building its own V8 engine family for decades, adopting the corporate Chevrolet 350 small-block and Cadillac Northstar engine only in the 1990s. All Oldsmobile V8s were assembled at plants in Lansing, Michigan while the engine block and cylinder heads were cast at Saginaw Metal Casting Operations.
Quad 4 is the name of a family of principally DOHC inline four-cylinder engines produced by General Motors' Oldsmobile division between 1987 and 2002; a single SOHC version was built between 1992 and 1994.
General Motors' Opel subsidiary in Europe designed a compact V6 engine with an unusual 54° vee angle. It was an iron block/aluminum head DOHC design with four valves per cylinder. All 54° engines were assembled at Ellesmere Port in England.
The Mitsubishi Sirius or 4G6/4D6 engine is the name of one of Mitsubishi Motors' four series of inline-four automobile engines, along with Astron, Orion, and Saturn.
The Mitsubishi 4G9 engine is a series of straight-4 automobile engines produced by Mitsubishi Motors. All are 16-valve, and use both single- and double- overhead camshaft heads. Some feature MIVEC variable valve timing, and it was the first modern gasoline direct injection engine upon its introduction in August 1996.
The GM Family I is a straight-four piston engine that was developed by Opel, a former subsidiary of General Motors and now a subsidiary of PSA Group, to replace the Vauxhall OHV, Opel OHV and the smaller capacity Opel CIH engines for use on small to mid-range cars from Opel/Vauxhall. The engine first appeared in the Opel Kadett D in 1979, and shortly afterwards in its Vauxhall badged sister – the Vauxhall Astra Mk.1 in 1980. Despite this, the previous Opel OHV engine continued to be sold in entry level versions of the Opel Kadett/Astra and Corsa throughout the 1980s.
The Family 0 is a family of inline piston engines that was developed by Opel, at the time a subsidiary of General Motors, as a low-displacement engine for use on entry-level subcompact cars from Opel/Vauxhall.
The Suzuki G engine is a series of three- and four-cylinder internal combustion engines manufactured by Suzuki Motor Corporation for various automobiles, primarily based on the GM M platform, as well as many small trucks such as the Suzuki Samurai and Suzuki Vitara and their derivatives.
The General Motors–Detroit Diesel V8 engine is a series of diesel V8 engines first introduced by General Motors for their C/K pickup trucks in 1982. Developed in collaboration with GM subsidiary Detroit Diesel, the engine family was produced by GM through 2002, when it was replaced by the new Duramax line. AM General's subsidiary General Engine Products (GEP) still produces a military variant of this engine for the HMMWV.
The Family II is a straight-4 piston engine that was originally developed by Opel in the 1970s, debuting in 1981. Available in a wide range of cubic capacities ranging from 1598 to 2405 cc, it simultaneously replaced the Opel CIH and Vauxhall Slant-4 engines, and was GM Europe's core mid-sized powerplant design for much of the 1980s, and provided the basis for the later Ecotec series of engines in the 1990s.
The Mazda L-series is a mid-sized inline 4-cylinder gasoline piston engine designed by Mazda as part of their MZR family, ranging in displacement from 1.8 to 2.5 liters. Introduced in 2001, it is the evolution of the cast-iron block F-engine. It was co-developed with Ford, who owned a controlling stake in Mazda at the time. Ford uses it as their 1.8 L to 2.5 L Duratec world engine and holds a license to develop engines based on the L-series in perpetuity.
The Chevrolet 153 cu in engine was an inline-four engine designed in the early 1960s for use in the Chevy II. It is a four-cylinder variant of the Turbo-Thrift six-cylinder engine. After 1970, GM ceased production of the 153 engine in North America because of low demand, but the engine continued to be used in cars in other markets around the world, notably in South Africa and South America. The engine was also standard equipment in the Jeep DJ-5A—used by the United States Postal Service—until American Motors bought Kaiser Jeep in 1970 and replaced the engine with the AMC straight-six in the DJ-5B. Currently descendants of the 153 engine are used in industrial and marine applications. The 153 engine is entirely different from the 151 cu in (2.5 L) Iron Duke engine introduced by Pontiac in 1977, most noticeably never having featured the Pontiac engine's crossflow cylinder head, but the two are often confused today.
Medium Gasoline Engine (MGE) is a medium-displacement 4-cylinder gasoline engine developed by Opel Automobile GmbH and marketed as 'SIDI Ecotec'.
The Opel cam-in-head engine (CIH) is a family of automobile engines built by former General Motors subsidiary Opel from 1965 until 1998, appearing extensively in Opel/Vauxhall badged cars during this period. Both four- and six-cylinder inline configurations were produced. The name derives from the location of the camshaft, which was neither cam-in-block nor a true overhead camshaft. In the CIH engine the camshaft is located in the cylinder head but sits alongside the valves rather than above them, so therefore effectively is still an overhead valve design. The valves are actuated through very short tappets and rocker arms. The engine first appeared in the Opel Rekord B in 1965, and was largely replaced in four-cylinder form by the GM Family II unit as Opel/Vauxhall's core mid-size engine in the 1980s, with the six-cylinder versions continuing until 1994 in the Omega A and Senator B. A large capacity 2.4L four-cylinder version continued until 1998.
The Medium Diesel Engine (MDE) is a four-cylinder diesel engine developed by Adam Opel AG and branded "1.6 CDTI Ecotec" in most markets. Opel also adds the marketing term "Whisper Diesel" in some markets, claiming relatively low levels of noise, vibration, and harshness. Production commenced in late 2013 at Szentgotthárd, Hungary. The MDE is Opel's first all-aluminum diesel engine and offers a power density of 85 hp (63 kW) per liter 136 PS in its most powerful version. Maximum power and torque have been increased versus the previous-generation 1.7-liter engine, while fuel consumption has been reduced by up to 10 percent compared with a 2.0-liter CDTI engine of similar power output. This new 1.6 CDTI engine will replace the current 1.7-liter and lower-powered 2.0-liter diesel engines in a wide range of Opel models, with more- and less-powerful versions to come. The most powerful version of this engine, delivering 136 PS at 3,500–4,000 rpm and 320 N⋅m (236 lb⋅ft) at 2,000 rpm, was first introduced in the 2013 Opel Zafira Tourer, and later in the 2014 Opel Astra J and restyled 2014 Opel Meriva B. In 2014, versions were released with power outputs of 110 and 95 PS.
