The IHC/McCormick Deering Type M gasoline engine was debuted in 1917 and built until 1937. All M engines were throttle governed and both low tension ignitor and high tension spark plug ignition systems were used. A unique feature of these engines was a completely enclosed, but dry crankcase. The crankshaft main bearings and rod were still greased by mechanical grease cups and the cylinder oiled by a drip oiler. All timing gears were inside, while the remaining parts, including the cam, were outside the crankcase. No oil was stored inside the engine.
