This is a list of all engines produced or used by Mitsubishi Fuso Truck and Bus Corporation. All engines are diesel unless stated otherwise.

Gasoline engines

The JH4 was an F-head engine based on the Willys Hurricane engine and its predecessor Willys Go-Devil sidevalve four, and was used to power early Mitsubishi Jeeps as well as Mitsubishi Fuso trucks and buses. It was of 2199 cc, had 69 HP and formed the basis for the KE31, a diesel engine of the same dimensions. Several other engines had been taken over from Mitsubishi Motors.

Diesel engines

KE series

4DQx

4DRx

4D3x

The 4D3x is a series of 4-cylinder OHV diesel engines.

4M4x

4M5x

The 4M50 is a series of 4-cylinder diesel engines with 4899 cc, bore × stroke 114 ×, gear driven, DOHC 4 valves per cylinder, and common rail direct injection with turbocharging and intercooler. The 4M51 is a bored out version of the 4M50 with 5249 cc from a bore and stroke of 118 ×. It is a four-cylinder diesel engine producing 140 - 155 PS.

4P1x

The 4P10 is a 2998 cc turbodiesel engine purchased by Daimler from FPT Industrial for the Mitsubishi Fuso Canter since 2009. Essentially it is an Fiat F1C. The 4P10 with common rail fuel system and high pressure piezo-injectors meets Euro 6 emission norms with Bluetec selective catalytic reduction system and was introduced as the new "Global Powertrain" for the Canter. Since the "General Export Models" retained the old Mitsubishi engines, the utilization of the "Global Powertrain" was limited to highly developed countries with strict exhaust gas emission limitations, e.g. Japan (starting with the 8th generation of the Canter only), Europe, and North America. In 2020, a revised version with improvements on torque, fuel economy and exhaust gas emissions appeared in Japan for the Canter under the denomination 4P10+.

4V2x

Bore 104 mm × stroke 115 mm, 3907 cc, OHV, gear-driven camshaft, based on the 4D37 engine. Common rail direct injection, turbo with intercooler.
