Four cycle, four cylinder air/oil cooled, horizontally opposed, direct drive engine with a wet sump, positive displacement lubrication system, 9.6:1 compression ratio, engine cranking accomplished by a geared Bendix-style starter mounted on the crankcase that engages an external ring gear, fuel delivery via a traditional diaphragm-style AC, plunger-driven pump assembly mounted on the rear accessory housing, a fuel servo mounted below the engine, and a flow divider to direct the fuel flow to nozzles installed in each cylinder head. The engine is attached to the airframe using a Dynafocal mount. IO-370-CM Same as the IO-370-CL except the aircraft mounting interface is conical. IO-370-C1F Same as the IO-370-CL except hot oil sump, straight barrel fins, different cylinder baffle configuration. IO-370-D3A Same as the IO-370-C1F except straight oil filter adapter; non-counterweighted, solid crankshaft. IO-370-DA3A Same as the IO-370-D3A except the timing is set to 22° to reduce power.
