The air and fuel that entered the cylinder during the first stroke are being compressed into a small space between the combustion chamber of the cylinder head and the top of the piston. power stroke - Answer️️ -the piston will be pushed down by the expanding gases created by the burning of the air and fuel mixture. Both valves remain closed until the piston reaches bottom dead center. exhaust stroke - Answer️️ -the exhaust valve opens and the piston pushes the burned air and fuel out of the open valve as it moves up to the tip of the cylinder. flywheel - Answer️️ -A _____ is a device used to store rotational energy. camshaft - Answer️️ -The _____ is a lobed shaft that is us
