According to the type of cylinder arrangement, engines are classified into four types

Inline Engine: In this type, the cylinders are arranged in one line. The length of the crankshaft is longer than that of the other types of engines, hence a limited number of cylinders are used. In this type, better balancing and more uniform torque is obtained.

V Engine: In this type, cylinders are arranged in the V shape at an angle of usually 60°. This engine is more economical and compact. For multi cylinder engines, the length of the crankshaft is much shorter than that of the inline engine. In this type, the engine height is also lower than it is in the inline engine.

Opposed Engine: In this type, the cylinders are arranged horizontally opposite to each other. This provides better mechanical balance. This type of engine can run smoothly even at a much higher speed. It also gives higher output. The length of the engine is too much and therefore engine has to be placed in the transverse direction in the vehicle.

Radial Engine: In this type, the cylinders are arranged radially. This type of engine is shorter, lighter and more rigid. Since it is rigid, a higher engine speed is possible, and a higher combustion pressure can be obtained. This leads to high fuel efficiency. The radial type engines are mostly used in aeroplanes.
