motion



intake - the cylinder must be filled with a flammable mixture of air and fuel during this event that occurs
in an internal combustion engine



compression - the mixture of air and fuel must be compressed into a smaller space and then ignited by a
spark



power - once the air and fuel mixture is ignited, the force of expanding, burning mixture can be used for
power production



exhaust - the burned mixture must be removed from the cylinder during this event that occurs in an
internal combustion engine



stroke - A _____ refers to the full travel of the piston in the cylinder.



intake stroke - the first of four strokes, the intake valve opens, the exhaust valve closes, and the piston
