The Mercedes-Benz M114 is a straight-six single overhead camshaft gasoline powered automobile engine with dual two-barrel Zenith 35/40 INAT carburetors or with Bosch D-Jetronic fuel injection system. The engine has a displacement of 152.4 cu in (2,497 cc), develops 96 kW (129 bhp; 131 PS), and has a maximum engine speed of 6300 rpm[1] with a 9:1 compression ratio.
Design and features
[edit | edit source]The M114 features a single overhead camshaft (SOHC) valvetrain operating two valves per cylinder, with a cast-iron cylinder block and an aluminium alloy cylinder head. In fuel-injected form, the engine used Bosch D-Jetronic electronic fuel injection, which provided more precise fuel metering and throttle response than contemporary carbureted systems.[1]
Applications
[edit | edit source]The M114 engine was used primarily in the Mercedes-Benz W114 and W115 series, including the 250 and 250 C models produced during the late 1960s and early 1970s.[2]
