Direct injection 2874 cc The successor of the OM617 engine family was the newly developed straight-5 diesel automobile engine OM602 from Mercedes-Benz used from 1980s up to 2002. With some OM602 Powered Mercedes-Benz vehicles exceeding 500000 or, it is considered to be one of the most reliable engines ever produced, a success which is only comparable with the famous OM617 engine.
It is closely related to the 4 cylinder OM601 and the 6 cylinder OM603 engine families of the same era.
The 5-cylinder OM602 was succeeded by the four-valve OM605 engine and later the OM612 and OM647 engines with turbocharger and common rail direct injection.
The engine
The Mercedes OM602 engine is a 5-cylinder diesel engine of 2497 or. The 2874 cc was used in the 310D and 410D Mercedes-Benz T1 and the Phase 1 Mercedes-Benz Sprinter vans (where it was modified for direct injection), the Ssangyong Musso, Korando and Rexton 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. The water pump is driven via the single serpentine belt, which also drives all other accessories.
On many OM602 engines 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.
Some later versions of the 2874 cc capacity unit use a Bosch VE-style rotary distributor injection pump with electronic control and have a significantly different combustion chamber as they use direct injection.
Preheating is by glow plugs with automatic control of preheating time.
