OM602 Engine Technical Data
The OM602 5-cylinder diesel engine was available in either naturally aspirated, or turbocharged variants of 2.5 or 2.9 L (2,497 or 2,874 cc) with two valves per cylinder. 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.
The OM602 camshafts and injection pump are driven by a duplex timing chain from the crankshaft, and a separate single-row chain drives the oil pump. The camshaft operates the valves via hydraulic bucket tappets with automatic valve clearance adjustment.
