Explanation of codes

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.

Configurations

Single-cylinder

These were used in Mitsubishi's very first vehicles, motor scooters and three-wheelers.

As fitted to the 1.25-tonne (2,760 lb) Mitsubishi "Mizushima" TM14G three-wheeled truck, the ME12 developed 27 PS (20 kW) at 3600 rpm. [2]


Two-cylinder/inline 2

Mitsubishi's smallest powerplants, most commonly found in their earliest models in the 1960s:

Three cylinder/inline-3

Four-cylinder/inline-4

Gasoline:

  • KE42, 1962 (Canter 1st generation 66kW, 2nd gen 66kW @ 4800 rpm, 3rd gen 1995cc, 70kW) or earlier til ???, on Canter replaced in January 1975
  • KE47, 1968 (Canter 2nd gen 70kW @ 4500 rpm, 172Nm @ 2800 rpm, 3rd gen 2315cc, 74kW) or later til January 1975 (Canter) or later

Diesels:

Two 2659 cc straight-4 normally aspirated and turbodiesels, 4DR5 and 4DR6, fitted to some Canter light trucks, and also fitted to the company's Jeep which it built under licence from Willys between 1953 and 1998. Also used in some larger forklift trucks.
  • 4DR5: Bore x stroke 92.0mm x 100.0mm. Capacity 2659cc. Compression ratio 20.0:1. Naturally aspirated power output 80PS @ 3,800rpm. Torque output 18.0 kg/m @ 2,200rpm. The indirect injected 4DR5 produced from naturally aspirated 75 to 80 PS (55 to 59 kW), while the turbocharged and intercooled versions produced a torque of 22.5 kg/m (220.65 Nm) at 2000 RPM and had a compression ratio of 21.5:1, with a maximum power of 100 PS (74 kW) at 3,300 rpm.
  • 4DR6 with direct injection has a lower compression ratio of 17.5 producing a torque of 21.0 kgm (205.94 Nm) at 2000 rpm with a maximum power of 94 PS (69 kW) at 3,500 rpm

Six-cylinder/inline-6/V6

Mitsubishi has three families of V6 engines, which have seen use in its midsize lines, coupés and compacts.

Eight-cylinder/V8

Willys Hurricane engine Motor vehicle engine

The Willys F4-134 Hurricane was an inline-4 piston engine and powered the famous Jeep CJ in the CJ-3B, CJ-5, and CJ-6 models. It was also used in the Willys 473 and 475 pickups, wagons, and sedan deliveries. It replaced the Willys Go Devil engine that was used in the MB Jeep and other early Jeep-based models like the Jeepster. This engine was also built by Mitsubishi for their license-built Jeep, as well as other applications.

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.

Mitsubishi Colt Motor vehicle

Mitsubishi Colt is a nameplate from Mitsubishi that has been applied to a number of automobiles since 1962. It was first introduced with a series of kei and subcompact cars in the 1960s, and then for the export version of the subcompact Mitsubishi Mirage between 1978 and 2002. Chrysler, Mitsubishi's longtime partner, also used the name when applying its long-running practice of rebadging Mitsubishi vehicles as the Dodge and Plymouth Colt captive imports for the North American market between 1970 and 1994.

Mitsubishi Astron engine Motor vehicle engine

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.

Mitsubishi Sirius engine Motor vehicle engine

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.

Subaru G Motor vehicle

The Subaru FF-1 G was a compact car from the 1970s, replacing the FF-1 Star. It was a front-wheel drive vehicle with a typical Subaru EA61 or EA62 flat-4 engine. The car also had independent torsion bar suspension and rack and pinion steering, inboard front drum brakes and dual radiators. The car used only a small radiator on starting, hastening warm up. Achieving 29 miles per US gallon, the Subaru quickly became a strong-selling import car in the United States.

Prince G engine Motor vehicle engine

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.

Mazda B series Series of pickup trucks made by Mazda

The Mazda B series is a series of pickup trucks that was manufactured by Mazda. Produced across five generations from 1961 to 2006, the model line began life primarily as a commercial vehicle, slotted above a kei truck in size. Through its production, Mazda used engine displacement to determine model designations; a B1500 was fitted with a 1.5 L engine and a B2600, a 2.6 L engine.

Subaru 1000 Motor vehicle

The Subaru 1000 is the first and only front wheel drive Subaru produced by Fuji Heavy Industries that was in the Japanese government "compact car" classification starting in 1966. Previous Subaru models such as the Subaru 360 and the Sambar had been rear-engined, rear wheel drive kei cars.

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.

Mitsubishi Fuso Canter Motor vehicle

The Mitsubishi Fuso Canter is a line of light-duty commercial vehicles manufactured by Mitsubishi Fuso Truck and Bus Corporation, part of Daimler Trucks, subsidiary of Daimler AG). 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 Neptune or 4G4 engine is a series of iron-block OHV inline-four engines built by Mitsubishi Motors from 1971 to 1979, alongside the Orion, Saturn, Astron, and Sirius. This was to be Mitsubishi's last OHV engine. The inability to clear new passenger car emissions rules for 1978 meant that the Neptunes were replaced by the 4G1 Orion. The Neptune continued to be built until 1979 for commercial vehicles, which suffered less restrictive environmental regulations.

Mitsubishi Mizushima Truck

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.

Toyota Y engine Motor vehicle engine

The Toyota Y engine is a design that is a combination of the Toyota T engine, and the Toyota R engine, in a way that's similar to how the Toyota F engine is a design of the Toyota Type B engine, and the Chevrolet inline-six. The Y engine has mostly only been used in commercial and off-road vehicles.
