The Mercedes-Benz OM605 is a inline-five cylinder (R5/I5) double overhead camshaft (DOHC) diesel engine with indirect injection manufactured by Mercedes-Benz between 1993 and 2001. It replaced the single overhead camshaft (SOHC) OM602 engine.
It uses a Bosch electronically controlled inline injection pump (ERE) except in the W124 where it uses a Bosch mechanically governed inline injection pump (Bosch M pump with RSF governor).
It is related to the straight-4 2.0 and 2.2 litre OM604 and the straight-6 3.0 litre OM606 engines.
Design
As per the OM602 the engine has a cast iron block and aluminum cylinder head, the block has 6 main caps, they are held by two bolts per cap. The head is a DOHC design with 4 valves per cylinder and split intake ports. As with the OM602 it has hydraulic bucket type lifters, thus eliminating periodic valve adjustment. Turbocharged engines were now intercooled, compared to their predecessors.
It has a double row timing chain that drives the injection pump and the camshafts, the sprocket is on the exhaust camshaft and both cams are connected by a gear drive, while the oil pump is driven by a separate single row chain.
