Mercedes-Benz OM616 engine

The Mercedes-Benz OM616 is a diesel inline-four engine family used in cars, vans and Unimogs in the 1970s and 1980s. It is a bored out version of the 2.2 litre OM615 that it replaced, displacing 2.4 litres and first making 65 PS. In August 1978 the pre-combustion chamber was revised for more swirl, the displacement was trimmed to 2,399 cc to suit European displacement taxes, and output rose to 72 PS. Applications include the 240D in the W115 and W123 and the MB 100 D. In 1982 Bajaj Tempo, now Force Motors, signed a licence deal with Daimler-Benz to build the engine in India, where it still powers light commercial vehicles. The OM prefix stands for Oelmotor.
