Intro: At Manassas, I have been flying a 172-M. This quick video will explain the engine of "my" aircraft.
Power plant: The 172M model. This model was manufactured from 1972 to 1976 and continued the engine design introduced with the I-model in 1968, namely the Lycoming O-320-E2D engine with 150 hp.
The Lycoming O-320 is a large family of 92 different normally aspirated, air-cooled, four-cylinder, direct-drive engines commonly used on light aircraft.
