Which of the following is the correct formula used to calculate engine displacement?Displacement = π × R 2 × L × N Displacement = π 2 × R × L × N Displacement = π × D × L × N Displacement = π × D × L 2 × N

To determine

The correct formula for calculating engine displacement.

Explanation

In an engine when the crankshaft rotates, the piston reciprocates from the top to bottom or bottom to top (i.e. between the top dead center and bottom dead center). As the piston moves the volume inside the cylinder changes.

Engine displacement (specified as a Cubic centimeter or CC) is referred to as the combination of the swept volumes of all the pistons inside the cylinders. The area of the piston is determined from the diameter of the piston (bore) and the stroke length is the distance traveled by the piston.

Thus, the engine displacement is calculated as follows:

Engine displacement= Area of the piston×Stroke Length×Number of cylinders

Engine displacement=
