The Mercedes-Benz OM647 is a straight-5 diesel engine produced by Mercedes-Benz. [1]
The engine utilizes a cast-iron cylinder block and an aluminum cylinder head. It is turbocharged and intercooled, and has four valves per cylinder and dual overhead camshafts.
A distinguishable aspect of the OM647 from its OM612 predecessor is its intake manifold, and the lack of a diesel fuel feed pump.
