Introduction to Cylinder Head
A cylinder head is a crucial component in an internal combustion engine. It sits atop 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 the fuel injectors. It plays a vital role in the engine's performance, as it controls the flow of air - fuel mixture into the cylinders and the expulsion of exhaust gases. A well - designed and high - quality cylinder head can improve engine efficiency, power output, and fuel economy, while also reducing emissions.
