 | | In an internal combustion engine, the cylinder head sits atop the cylinders and consists of a platform containing most part of the combustion chamber and the location of the valves and spark plugs. |
 | | A V engine usually has two cylinder heads, one at each end of the V, although Volkswagen, for instance, has recently produced a V6 where the angle between the cylinder banks is so narrow that it utilizes a single head. |
 | | The cylinder head is key to the performance of the internal combustion engine, as the shape of the combustion chamber, inlet passages and ports (and to a lesser extent the exhaust) determines a major portion of the volumetric efficiency and compression ratio of the engine. |
