The successor of the '''[[OM 617]]''' engine family was the newly developed straight-5 Diesel automobile engine '''[[OM 602]]''' from Mercedes-Benz used from 1980s up to 2002. With some Mercedes-Benz 250D/E250D diesels exceeding 500,000 or 1,000,000 miles, it's considered to be the one of the most reliable engines ever produced, a success which is only comparable with the famous OM617 engine. 

The 5-cylinder OM602 was succeeded by the four valve engine OM605 (E250D 20V) and later the OM612 and OM647 with turbo charger and Common Rail Direct Injection (C/E/ML 270CDI).

==The engine==
The '''Mercedes OM602''' engine is a 5 cylinder diesel engine of 2497cc. The engine was also increased in capacity to 2874cc (2.9L) and used in the Phase 1 Mercedes Sprinter vans, the Ssangyong Musso and Korando range and even in the 1996-1999 models of the E-class. 
It was available in either naturally aspirated or turbocharged variants with two valves per cylinder.

The camshafts and injection pump are driven by duplex chain from the crankshaft. A separate single row chain drives the oil pump. The camshaft operated the valves via hydraulic bucket tappets; valve clearance adjustment is automatic.

On earlier models of 2497cc Fuel injection is indirect. A Bosch PES in-line injection pump is used, with a mechanical governor and vacuum-operated stop control. The pump is lubricated by a connection to the engine oil circulation and the fuel lift pump is mounted on the side of the injection pump. 

The later, 2.9L capacity unit uses a Bosch VE style rotary distributor injection pump with electronic control. This larger capacity version uses direct injection.

Preheating is by glow plugs with automatic control of preheating time.
