This is a list of engines produced by Mitsubishi Motors since 1964, and its predecessors prior to this.
The Mitsubishi zaibatsu had been broken up into three companies by the US occupying forces. Automobile and truck engines were mainly built by three branches of one of these companies, Central Heavy Industries (Shin-Mitsubishi Heavy Industries from 1952). These three branches (Mizushima, Nagoya, and Kyoto Engineering Works) were established as clusters of the many small aircraft factories built during the war. [1] Thus, Mizushima developments gained the ME code, followed by a numerical, while engines developed in Nagoya became the NE-series and Kyoto-developments were named KE. The numbers do not in any way relate to each other or across letter codes and were purely issued in order of development. In 1964 the three companies were merged into Mitsubishi Heavy Industries and eventually a new naming system emerged.
Since the introduction of the 2G10 engine in October 1968, Mitsubishi engines use a four-digit naming convention:
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.
These were used in Mitsubishi's very first vehicles, motor scooters and three-wheelers.
Mitsubishi's smallest powerplants, most commonly found in their earliest models in the 1960s:
Gasoline:
Diesels:
Mitsubishi has three families of V6 engines, which have seen use in its midsize lines, coupés and compacts.
A straight-four engine is a four-cylinder piston engine where cylinders are arranged in a line along a common crankshaft.
After an early flirtation with V-twin engines, Mazda's small cars of the 1960s were powered by OHV straight-2 and straight-4 engines. This family lasted from 1961 until the mid-1970s. Today, Mazda's keicars use Suzuki engines. It was produced at the Hiroshima Plant in Hiroshima, Japan.
A multi-valve or multivalve engine is one where each cylinder has more than two valves. A multi-valve engine has better breathing, and with more smaller valves may be able to operate at higher revolutions per minute (RPM) than a two-valve engine, delivering more power.
The Mitsubishi Astron or 4G5/4D5 engine, is a series of straight-four internal combustion engines first built by Mitsubishi Motors in 1972. Engine displacement ranged from 1.8 to 2.6 litres, making it one of the largest four-cylinder engines of its time.
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 Minica is a model series of kei cars, produced by Mitsubishi Motors Corp. (MMC) over five generations, from 1962 to 2011, mainly for the Japanese domestic market.
The Prince G-series engine was the company's only straight-four and straight-six engines which began production in 1955. A number of variations were made, with both OHV and OHC heads. A diesel four-cylinder with 1.9 L (1,862 cc) was also built, called the D-6. The G series was used in the Skyline, the Laurel, and the Gloria from the 1950s to the early 1970s.
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 Mitsubishi 4M4 engine is a range of four-cylinder diesel piston engines from Mitsubishi Motors, first introduced in the second generation of their Montero/Pajero/Shogun SUVs. They superseded the previous 4D5 engine family, main differences are enlarged displacements and the utilization of one or two over-head camshafts. Originally available only as a 2835 cc intercooled turbo, detail improvements in 1996 and a larger 3.2 litre option in 1999 served to improve power, torque, fuel economy and emissions. The final version has 3.0 litres swept volume and Common rail direct injection.
The Mitsubishi Fuso Canter is a line of light-duty commercial vehicles manufactured by Mitsubishi Fuso Truck and Bus Corporation, part of Daimler Truck, subsidiary of Mercedes-Benz Group. The Canter is manufactured since 1963, now in its eighth generation. The Canter is named after the English word describing the gait of a horse, emphasising the 'thoroughbred' nature of Mitsubishi trucks.
The Mitsubishi KE engine is a range of engines produced by Mitsubishi Motors during the 1960s and early 1970s. They were extensively used in the various Colt-branded vehicles the company produced from 1963.
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 Nissan ZD30 engine family is a 3.0-litre inline-four cylinder diesel engine with a bore and stroke of 96 mm × 102 mm, that replaced the Nissan QD, BD and TD engines. At Renault it also replaced the Sofim 8140 engine and is the only truck diesel engine which remained with Nissan Motors when they sold Nissan Diesel to Volvo trucks in 2007.
The Mitsubishi Mizushima is the first of a series of three-wheeled cargo carriers made in Japan by Mitsubishi between 1947 and 1962. A number of prototypes were built in 1946, leading to series production beginning in May 1947. Along with the Silver Pigeon scooter it represented the company's first contributions to the Japanese post-war personal transport boom.
Mitsubishi Fuso Truck of America, Inc. (MFTA) is a wholly owned subsidiary of Mitsubishi Fuso Truck and Bus Corporation (MFTBC), Kawasaki, Japan, itself a part of Daimler Truck based in Logan Township, New Jersey, United States. MFTA imported and marketed Class 3 through Class 5 medium-duty cabover trucks through more than 200 dealer locations in the United States and Canada, until 2021. As of 2019, MFTA imported and marketed diesel-powered, gas-powered, and electric trucks. According to the company, more than 100,000 Mitsubishi Fuso standard, 4-wheel-drive and crew cab trucks had been sold in the Canadian and U.S. markets since the company's founding. Applications included beverage, catering, refrigerated and dry cargo delivery, vehicle recovery, towing, pest control, plumbing, light construction and landscaping, overlanding, among others.
The ME21/24 engine was Shin Mitsubishi Heavy-Industries' replacement for the 309 cc single-cylinder overhead valve ME20 engine. Unlike its predecessor, this was a two-stroke, a concept to which Mitsubishi was to prove faithful for its smallest engines until the 1972 introduction of the Vulcan 2G21.
