69.112.168.94: /* Two cylinder */ 2G10 updates

This is a list of [[Internal combustion engine|engines]] produced by [[Mitsubishi Motors]] since 1964, and its predecessors prior to this.

==Explanation of codes==
Mitsubishi engines designed since 1970 use a four-digit naming convention:
*The first (digit) signifies the number of [[Cylinder (engine)|cylinders]]; "2" = [[straight-2]], "3" = [[straight-3]], "4" = [[straight-4]], "6" = [[V6]], "8" = [[V8]].
*The second (letter) formerly referred to the fuel type; "D" = [[diesel]], "G" = [[gasoline]]. However, since the 1980s, this has changed. Two engine families were introduced using the letter "A" to denote that all the engines in the family had an [[alloy]] [[cylinder head]]. Their latest engines, however, do not follow any previous conventions (e.g. [[Mitsubishi 4M engine|4M4x]], [[Mitsubishi 3B engine|3B2x]], etc).
*The third (digit) previously denoted the engine family. Five of the "4Gxx" [[straight-4]] engine families had distinct names; "4G1" = [[Mitsubishi Orion engine|Orion]], "4G3" = [[Mitsubishi Saturn engine|Saturn]], "4G4" = [[Mitsubishi Neptune engine|Neptune]], "4G5" = [[Mitsubishi Astron engine|Astron]], and "4G6" = [[Mitsubishi Sirius engine|Sirius]].
*The fourth (digit) is the specific engine model within the family. It is not a guide to its place ''within'' that family, nor is it a guide to the capacity of the engine.

There may also be supplementary letters after the initial four characters. "T" can indicate that the engine is turbocharged (e.g. ''4G63T''), "B" that this is the second version of the engine (e.g. ''4G63B''). Where engine codes are used which include the supplemental letters, the first digit denoting the number of cylinders may be omitted, so ''4G63T'' may be seen as ''G63T''.

==Configurations==
===Two cylinder===
Mitsubishi's smallest powerplants, most commonly found in their earliest models in the 1960s:
* '''[[Mitsubishi 2G engine|2G]]''' — First introduced in the second generation [[Mitsubishi Minica|Minica]] in 1969 to replace the air-cooled '''ME21''' powerplant. While water-cooled, the ''2G10'' was a two-stroke, like its predecessor. It was complemented in 1972 by a new four-stroke [[OHC]] design called ''Vulcan'' which saw service throughout the 1970s.
* '''ME21/ME24''' — A 359 cc twin cylinder [[OHV]] engine in the [[Mitsubishi 360|360]] [[pickup truck]] and the first generation [[Mitsubishi Minica|Minica]].
* '''NE19A''' — The 493 cc twin cylinder engine in the [[Mitsubishi 500]], the first passenger car built by the company after the [[Second World War]].

===Three cylinder===
Mitsubishi's smallest modern engines are primarily designed for the [[Japan]]ese-market ''[[kei car]]'' class:
* '''[[Mitsubishi 3A9x engine|3A9x]]''' — The ''3A91'' used in the new [[Mitsubishi Colt|Colt]] in 2005.
* '''[[Mitsubishi 3B engine|3B2x]]''' — The ''3B20'', found in the 2003 [[Mitsubishi i]], uses a 660 cc [[DOHC]] with the company's [[MIVEC]] [[variable valve timing]] and an [[intercooler|intercooled]] [[turbocharger]], and was designed with the aim of exceeding Japan's 2010 [[fuel economy]] requirements.
* '''[[Mitsubishi 3G engine|3G]]''' — Introduced in the 1980s, initially as a 550 cc, and enlarged to 657 cc in 1990 when changes in kei car regulations permitted. High performance versions used a [[Multi-valve|15v]] head, and can claim the distinction of being the [[List of automotive superlatives#Engine technologies|first production engine to feature five valves per cylinder]], beating rival designs from [[Bugatti]], [[Toyota]] and [[Audi]] to the market by at least a year. The ''3G83T'' in the [[Mitsubishi Minica|Minica Dangan]] was the first [[turbocharger|turbocharged]] kei car available in Japan.

===Four cylinder===
Mitsubishi has developed twelve families of [[straight-4]] engines:
* '''[[Mitsubishi 4A3x engine|4A3x]]''' — A 660 cc engine designed for kei cars in 1994, enlarged to 1100 cc in 1999.
* '''[[Mitsubishi 4A9x engine|4A9x]]''' — A 1.3 and 1.5 L engine introduced in the 2003 [[Mitsubishi Colt|Colt]].
* '''[[Mitsubishi GEMA engines|4B]]''' — The newest family of [[straight-4]] engines being developed in a joint-venture with [[DaimlerChrysler]] and [[Hyundai]] known as the [[Global Engine Manufacturing Alliance]] (GEMA), all featuring [[aluminum]] [[engine block]], [[DOHC]] heads, 4 valves per cylinder and [[MIVEC]] variable valve timing. The first of these are the ''4B11'' 2.0 L and ''4B12'', a 2.4 L fitted to the 2007 [[Mitsubishi Lancer|Lancer]] and [[Mitsubishi Outlander|Outlander]].
* '''4DRx''' — Two 2659 cc [[straight-4]] normally aspirated and [[turbodiesel]]s, ''4DR5'' and ''4DR6'', fitted to some Canter light trucks, and also fitted to the company's [[Mitsubishi Jeep|Jeep]] which it built under licence from [[Willys]] between 1953 and 1998,
* '''[[Mitsubishi Orion engine|4G1x "Orion"]]''' — 1.2 L to 1.6 L. First introduced in the 1978 [[Mitsubishi Colt|Colt]], and now the basis for the high performance variant of the 2003 version.
* '''[[Mitsubishi Saturn engine|4G3x "Saturn"]]''' — Ranging in size from 1.2 L to 1.8 L, this family first saw service in the 1969 [[Mitsubishi Galant|Colt Galant]].
* '''[[Mitsubishi Neptune engine|4G4x "Neptune"]]''' — 1.2 L to 1.4 L [[straight-4]] engines available in the [[Mitsubishi Lancer|Lancer]] and [[Mitsubishi Galant|Galant]] in 1979.
* '''[[Mitsubishi Astron engine|4G5x "Astron"]]''' — Offered from 1972 in capacities from 2.0 L to 2.6 L, the Astron family pioneered the modern use of twin [[balance shaft]]s in a [[straight-4]] configuration. The system, introduced in 1975 and dubbed "Silent Shaft", built on the patents of [[Frederick Lanchester]] which Mitsubishi had obtained, and proved a lucrative venture when it was licensed to numerous other manufacturers.
* '''[[Mitsubishi Astron engine|4D5x "Astron" diesel]]''' — Also part of the "Astron" family, the 2.3 L was the first diesel engine to be fitted to a Japanese passenger car. The subsequent 2.5 L version, introduced in 1986, is still in production, a popular choice in its line of [[pickup trucks]] where it is regarded as rugged, reliable and inexpensive to maintain.
* '''[[Mitsubishi Sirius engine|4G6x "Sirius"]]''' — Available in capacities from 1.6 L to 2.4 L, this was the favoured performance variant for Mitsubishi. The ''4G61T'' powered their [[Mitsubishi Colt|Colt Turbo]], while the ''4G63T'', first introduced in the 1980 [[Mitsubishi Galant|Galant]], went on to see service in the [[Mitsubishi Sapporo|Sapporo]] and [[Mitsubishi Starion|Starion]] coupés during the so-called "turbo era" of the 1980s, before creating for itself an illustrious motorsport heritage as the powerplant under the hood of the [[World Rally Championship]]-winning [[Mitsubishi Lancer Evolution|Lancer Evolution]]. A [[United Kingdom|UK]]-market Evo known as the FQ400 had a 298 kW (405 PS) version of the ''Sirius'', making it the most powerful car ever sold by Mitsubishi.
* '''[[Mitsubishi 4G9x engine|4G9x]]''' — 1.5 L to 2.0 L. The first modern [[gasoline direct injection]] (GDI) engine, in the [[Mitsubishi Carisma]], was an 1834 cc ''4G93'' straight-4.
* '''[[Mitsubishi 4M engine|4M]]''' — Mitsubishi's replacement for the '''"Astron"''' diesel, available as a 2.8 L, and later as a 3.2 L with direct injection.
* '''[[Mitsubishi KE engine|KE]]''' — A range of [[OHV]] [[straight-4]]s powering the [[Mitsubishi Colt|Colt]] range in the 1960s.

===Six cylinder===
Mitsubishi has three families of [[V6]] engines, which have seem use in its midsize lines, coupés and compacts.
* '''[[Mitsubishi 6A engine|6A]]''' — The smallest of these, the 1.6 L, was introduced in the [[Mitsubishi Mirage]] MX in 1992, and remains the [[List of automotive superlatives|smallest modern production V6]]. Larger versions powered the higher-spec versions of their family cars, with both the ''6A12'' 2.0 L and the ''6A13'' 2.5 L being given twin-turbo setups for the latter generations of the [[Mitsubishi Galant VR-4]].
* '''[[Mitsubishi 6B engine|6B]]''' — The newest family of [[V6]] engines featuring [[DOHC]] and [[SOHC]] heads and [[MIVEC]] [[variable valve timing]]. The first of these is the ''6B31'' 3.0 L fitted to the 2007 [[Mitsubishi Outlander|Outlander]].
* '''[[Mitsubishi 6G engine|6G "Cyclone V6"]]''' — First seen in the 1986 [[Mitsubishi Debonair|Debonair]] and [[Mitsubishi Diamante|Diamante]] as a 2.0 L and 3.0 L, it 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. Subsequent 3.5 L versions were also popular in their [[SUV]] range, especially with [[gasoline direct injection|GDI]]. Now expanded to 3.8 L with the ''6G75'' which underpins the newest versions of the Galant, [[Mitsubishi Eclipse|Eclipse]] and [[Australia]]n-built [[Mitsubishi 380]].
* '''[[Mitsubishi KE engine|KE64]]''' — A [[straight-6]] derivative of the '''KE4x''' straight-4 engines developed for the first [[Mitsubishi Debonair|Debonair]] from the 1960s [[Mitsubishi Colt]].
* '''[[Mitsubishi Saturn engine|"Saturn 6"]]''' — A 2.0 L [[straight-6]] variant of the ''Saturn'' straight-4 was made for the [[Mitsubishi Debonair]] in the 1970s to replace the '''KE64'''.

===Eight cylinder===
* '''[[Mitsubishi 8A engine|8A]]''' — For its Japan-only [[Mitsubishi Proudia|Proudia]] and [[Mitsubishi Dignity|Dignity]] models, Mitsubishi built an alloy-headed 4.5 L [[V8]] with [[gasoline direct injection|GDI]]. The vehicles proved unsuccessful, and were quickly discontinued. However, the range had been developed in conjunction with the [[Hyundai Motor Company]], whose [[Hyundai Equus]] fared much better.

===Other engines===
* '''[[Mitsubishi GEMA engines|GEMA engine]]''' — See the '''4B''' range above.
