Introduction to Cylinder Head
The cylinder head is a crucial component in an internal combustion engine. It is located at the top of the engine block and seals the cylinders, forming the combustion chamber. The cylinder head houses several important parts, such as the intake and exhaust valves, spark plugs (in gasoline engines), and fuel injectors. It plays a vital role in the engine's performance, including air - fuel mixture intake, combustion, and exhaust gas expulsion. A well - designed and manufactured cylinder head can improve engine efficiency, power output, and fuel economy, while also ensuring reliable operation and durability.
