Mercedes-Benz OM 315 engine

The Mercedes-Benz OM 315 was a six-cylinder diesel engine for medium-heavy and heavy trucks, derived in 1950 from the prewar OM 67/4. It had a larger displacement and more power than that engine and, like it, used prechamber injection. It belongs to the large OM 300 series, whose origins reach back to the mid 1930s through the OM 67 and which was replaced from 1970 by the OM 400 series. In 1964 the OM 315 was converted to direct injection and renamed OM 360, and a somewhat smaller version, the OM 327, was added whose output could take the place of the earlier prechamber engine. The old OM 67/4 itself had been renamed OM 325 in 1954 with unchanged displacement, and it was dropped in 1964 in favour of the smaller but stronger OM 352.
