. Camshaft forces the intake valve open automatically at or slightly before the piston starts down. The air-fuel mixture is drawn into the cylinder. At the same time, the exhaust valve remains closed during this downward movement. This valve closure prevents the entering air-fuel charge from escaping through the exhaust port. After the piston reaches the Bottom Dead Center （BDC） of its first stroke, the cylinder is practically full of an air-fuel charge. The drawing of an air-fuel charge into the cylinder in this manner, during the downward movement of the piston, constitutes the intake stroke （Fig.1-2a

The diameter of the piston is called the bore. The air or air–fuel mixture is drawn into the cylinder through the intake valve, and the combustion products are expelled from the cylinder through the exhaust valve

The piston reciprocates in the cylinder between two fixed positions called the top dead center (TDC)—the position of the piston when it forms the smallest volume in the cylinder—and the bottom dead center (BDC)—the position of the piston when it forms the largest volume in the cyline

2．Tappet, Pushrods and Rocker Arms Tappet rests on a cam of the camshaft. The pushrod is a metal rod that fits between the tappet and the rocker arm. Its function is to transmit cam lobe lift to the rocker arm assembly. The rocker arm is nothing more than a lever. Its function is to convert the up wardmotion of a pushrod into downward motion that compresses the spring and opens the valve.
（2） The Cylinder Head The cylinder head is bolted to the cylinder block. The top of the cylinder block is covered with the cylinder head which contains the combustion chamber （Fig.2-1）.
