It is used on high-performance engines, such as that in the new Lamborghini Aventador and the McLaren MP4 12C, though nowadays the angle between the valves is usually less than the classic 90, as we can see in the power unit developed by Bentley Motors for their new Bentley Mulsanne. The hemispherical layout requires the use of one or two overhead camshafts – or one side camshaft associated with complicated rocker and push-rod gear – to operate the two rows of valves. Its shape assists the crossflow of gases, which enter the cylinder from one side of the engine and are exhausted from the other.

This gives room for large and free-flowing inlet tracts, arranged so that the mixture enters the chamber easily and with a swirling motion. The good gas flow resulting from the unobstructed opening of its large valve gives the hemispherical head a high volumetric efficiency.

This means it can ‘breathe deeply’, drawing in a large volume of gas for the space available, although this space is never completely filled. With efficient combustion, the hemispherical head gives a high power output.
However, the modern tendency towards larger cylinder bores and shorter piston strokes enables valves on an ordinary in line engine, without hemispherical combustion chambers, to be big enough for most normal requirements. Such valves do not need special camshafts or rocker arrangements, making the engine less costly to produce.
