What is cylinder head?

A cylinder head is a component of an internal combustion engine that seals the top of the cylinder and forms the combustion chamber. It is typically made of metal and is bolted to the cylinder block. The cylinder head contains valves that control the flow of air and fuel into and out of the cylinder, as well as spark plugs or injectors that ignite the fuel.

The cylinder head is an important part of the engine and must be able to withstand high temperatures and pressures. It is also critical that the cylinder head is properly sealed to prevent leaks. A leak in the cylinder head can cause a loss of compression and power, as well as damage to other engine components.

Cylinder heads can vary in design depending on the type of engine. For example, some engines have a single cylinder head that covers all of the cylinders, while others have multiple cylinder heads. The design of the cylinder head can also affect the performance of the engine. For example, some cylinder heads are designed to improve airflow, which can lead to increased power and efficiency.

Cylinder heads can also be used to control the emissions of an engine. For example, some cylinder heads are designed to reduce the amount of pollutants that are released into the atmosphere.

Cylinder heads are an essential part of an internal combustion engine and must be properly maintained to ensure the engine's performance and durability.
