Mercedes-Benz M114 engine

The Mercedes-Benz M114 is a straight-six, single overhead camshaft petrol engine built by Mercedes-Benz. It was offered with a pair of two-barrel Zenith 35/40 INAT carburettors or with the Bosch D-Jetronic fuel injection system. Its displacement is 2,497 cc (152.4 cubic inches), it develops 96 kW (129 bhp, 131 PS), and its maximum speed is 6,300 rpm with a compression ratio of 9 to 1. The sources describe it only briefly: the Wikipedia article is a short stub that gives the layout, induction and rated figures but does not state the years of production or the vehicles that used it, so those facts are left open here rather than guessed.
