What are the four strokes of a four-cylinder reciprocating engine - ANSWER
Intake, compression, power, exhaust
What anomaly is the result of the fuel/air charge igniting before the spark plug
fires - ANSWER Pre-ignition
How many degrees of rotation is required of the crankshaft to complete a two-
stroke cycle - ANSWER 360
The horsepower resulting from the engine and propeller combination is
________? - ANSWER thrust horsepower [THP]
What is meant by this placement in a reciprocating engine - ANSWER The
