Basic Concepts of a Cylinder Head

A cylinder head is a component of an internal combustion engine. It sits atop the engine block and houses several key elements, including the valves, spark plugs (in gasoline engines), and fuel injectors (in diesel engines). The cylinder head forms the combustion chamber, where fuel is ignited to produce power. It also facilitates the opening and closing of valves to allow the intake of air and fuel and the expulsion of exhaust gases. Additionally, the cylinder head contributes to sealing the combustion chamber, ensuring that the pressurized gases produced during combustion are contained within the engine ³.
