A gasoline engine generates power by burning a volatile liquid fuel and initiates ignition with an electric spark. The most common engine in the world is the “four-stroke, spark-ignited, homogenous charge, gasoline powered engine” – in other words, a car engine.

These engines are often classified based on the following characteristics: application, type of fuel and method of injection, ignition, reciprocating piston or rotary, cylinder arrangement, strokes per cycle, cooling system, and valve type and location.
