The Mitsubishi 4M4 engine is an in -line 4-cylinder diesel engine available only at first as 2835 cc intercooled turbo, detail improvements in 1996 and a larger 3200 cc and later a 3.0L. Manufactured by Mitsubishi Motors for SUVs, and was first installed in the second-generation Mitsubishi Pajero. The 4M4 type was developed to update the predecessor 4D5 type.
The original 4M40 model had a 2.8L intercooler turbo with a cast iron cylinder block. It was improved in 1996, and a 3.2L engine with a larger displacement appeared SOHC, DOHC in 1999, improving output, torque, fuel efficiency, and exhaust gas concentration.
