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 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 Mazda B-series is a small-sized, iron-block, inline four-cylinder engine with belt-driven SOHC and DOHC valvetrain ranging in displacement from 1.1 to 1.8 litres. It was used in a wide variety of applications, from front-wheel drive economy vehicles to the turbocharged full-time 4WD 323 GTX and rear-wheel drive Miata.
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 6G7 series or Cyclone V6 engine is a series of V6 piston engines from Mitsubishi Motors. Five displacement variants were produced from 1986 to 2021, with both SOHC and DOHC, naturally aspirated and turbo charged layouts. While MIVEC variable valve timing has also been implemented in some versions the 2.5, 3.0, and 3.5 L versions were also available with gasoline direct injection. This engine has been the flagship powerplant of the company except when they briefly built a V8 in 1999–2001. The staple of their high-end sedans, it was given twin-turbos for the Mitsubishi GTO, and became the most powerful car ever built by the company at the time.
The Circle L is an automobile engine produced by GM Powertrain Poland in Poland. It is a 1.7 L; 102.9 cu in (1,686 cc) inline-four 16-valve turbocharged diesel engine originally designed by Isuzu but now owned by General Motors. The engine was produced in Europe by General Motors for use in the Opel, Vauxhall and Chevrolet vehicles and by Honda for use in the Civic compact car.
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 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 Volvo B21 is a slanted straight-four engine first used in the Volvo 200 series, meant to replace the B20. The B21 and all derived engines are often referred to as red block engines for the red paint applied to the block. The primary differences when compared to the B20 was the switch to a SOHC in place of the older pushrod configuration, and an aluminum crossflow cylinder head versus the iron head of the B20.
The MA is a straight-4 SOHC 0.9 L, 1.0 L, or 1.2 L engine first introduced in 1982 by Nissan, intended primarily for the K10 series Micra/March model. It shares design similarities with the older E engine, with an 8-valve hemispherical cylinder head but differs in that it uses an aluminium cylinder block. Unusually, the specified ignition timing for the MA10 running on the specified 90 RON gasoline was 2 degrees after top dead centre, reflecting a very high flame speed in the compact combustion chambers.
The Mitsubishi 3G8 engine is a range of three-cylinder powerplant from Mitsubishi Motors, introduced in the fifth generation of their Mitsubishi Minica kei car. In common with other contemporary engines in the class, it could be specified with many advanced technologies despite its diminutive size, including multi-valve cylinder heads and double overhead camshafts. The top-of-the-line Dangan ZZ variant was also the first kei car to benefit from turbocharging. In 1987 Mitsubishi was the first manufacturer to supercharge a kei vehicle, and in 1989 became the world's first production car to feature five valves per cylinder, ahead of similar developments by Bugatti, Audi, Ferrari and Toyota.
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 Mitsubishi 4A3 engine is a range of alloy-headed inline four-cylinder engines from Mitsubishi Motors, introduced in 1993 in the sixth generation of their Mitsubishi Minica kei car. It shares a 72 mm (2.8 in) bore pitch with the 3G8-series three-cylinder engines, but has a considerably shorter stroke so as to stay beneath the 660 cc limit imposed by the Kei class.
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.
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 Suzuki K engine family is a series of automobile engines from Suzuki, introduced in 1994. Displacements range from 0.7 L to 1.5 L. All engines have aluminium cylinder blocks with three or four cylinders in-line. Cylinder heads have two overhead camshafts, driven by chain, and four valves per cylinder. Fuel is gasoline/petrol, metered by multipoint fuel injection or direct injection. Some variants are turbocharged.
