THE READ FOR SPEED by Ned Erkman
CHAPTER 3


Basic Functions

The cylinder head is located on top of the engine, directly above the cylinders, therefore being referred to as the cylinder head.

The cylinder head performs three basic functions that affect power production and engine acceleration. The intake ports flow air and fuel into the cylinder, the combustion chamber promotes the combustion process within the cylinder and the exhaust port allows the exhaust to exit the cylinder.

When the intake and exhaust valves are closed, the cylinder head becomes the primary restriction for airflow in the engine. Since the intake and exhaust valves in the cylinder head create the biggest restriction for airflow when closed, modifications are necessary to improve the movement of air, fuel and exhaust through the cylinders and ports when the valves are open.
