Attached to the rear end of the crankshaft is a heavy rotating part called the flywheel.Its purpose is to store energy and retuen it to the engine when needed to pump the gases into and out of the combustion chamber.Actually,a piston moves up and down the cylinder four times in order to complete each cycle of drawing in,compressing,delivering power,and expelling the spent gases from the combustion chamber.
