Most cars, for example, have more than one cylinder. Cylinders in multi-cylinder engines are arranged inline, in a V shape, or flat (also called horizontally opposed or boxer). The arrangements of cylinders can vary.
 Series Engine
Cylinders are lined up next to each other leading in the same direction. Cylinders located in a series such as this are usually in long, narrow engines.
 Opposed Cylinder Type Engine
An engine that is shorter but broader than in a series type is known as an opposed cylinder-type engine. This type of cylinder configuration is expensive and more susceptible to damage because the cylinders are spread far apart and require separate camshafts and carburetors.
 V-shape Cylinder Engine
The V-shaped cylinder configuration is very common and a good combination of the other two designs available. The shape of the engine is not long or high and the cylinders are positioned closer together.
