The piston moves away from cylinder head, the intake port opens, fuel/air mixture is drawn in the cylinder.
Intake
The piston moves back toward the cylinder head, intake port close, fuel/air mixture is compressed.
Compression
The spark ignites the compressed fuel/air mixture forcing the piston down the cylinder and revolving the crankshaft
Power/Ignition
As the piston moves towards the cylinder head for the second time, the exhaust port opens, burnt gases are forced out of the cylinder.
Exhaust
abnormally rapid combustion due to low octane grade fuel, too lean fuel/air mixture, high cylinder head temperature
Detonation
Gasoline powered piston is most common propulsion system used in general aviation. Similar to automobile engine but it is lighter burns more highly refuse fuel and is aircooled.
The Reciprocating Engine
Types of Engine
Piston engine and Turbine engine
Turbine engine
Turbo jet – missile, Concorde, jet
Turbo fan – used by commercial aircraft
Turbo props – with propeller
turbo shaft - helicopter
