This is also common for motorcycles, and such head/cylinder components are referred to as barrels. Some engines, particularly medium- and large-capacity diesel engines built for industrial, marine, power generation, and heavy traction purposes (large trucks, locomotives, heavy equipment, etc.) have individual cylinder heads for each cylinder ...
Cylinder head of the Nissan VQ35DE engine. In engine design, the penta engine (or penta head) is an arrangement of the upper portion of the cylinder and valves that is common in engines using four valves per cylinder. [1] Among the advantages is a faster burn time of the air-fuel mix. [2]
A hemispherical head ("hemi-head") gives an efficient combustion chamber with minimal heat loss to the head, and allows for two large valves.However, a hemi-head usually allows no more than two valves per cylinder due to the difficulty in arranging the valve gear for four valves at diverging angles, and these large valves are necessarily heavier than those in a multi-valve engine of similar ...
These engines were based on the Hemi engines, using the same blocks and crankshaft parts, but completely different cylinder heads, pushrods, exhaust manifolds and pistons. They were called Polyspheric or Poly engines, because they featured polyspherical-shaped (meaning "more than one sphere") combustion chambers. These combustion chambers were ...
The head is machined flat, with recesses only for inlet and exhaust valves, spark plugs, injectors and so on. The combustion chamber itself is contained within a dished depression in the top of the piston. The Heron head is suitable for petrol and diesel engines, for ohv and ohc valve-gear, and for small and large engine displacement capacities.

1919 Napier Lion II aircraft engine with three cylinder banks. Any design of motor/engine,be it a V or a boxer can be called an "in-line" if it's mounted in-line with the frame/chassis and in-line with the direction of travel of the vehicle.When the motor/engine is across the frame/chassis this is called a TRANSVERSE motor.Cylinder arrangement is not in the description of how the motor/engine ...
