Engine displacement problem

First, let's take a look at one of the most common engine parameters-engine displacement. Engine displacement is the sum of the working volume of each cylinder of the engine, generally expressed in liters (L). The cylinder working volume refers to the gas volume swept by the piston from top dead center to bottom dead center, also known as single cylinder displacement, which depends on the cylinder diameter and piston stroke. Engine displacement is a very important engine parameter. It can represent the size of the engine more than the cylinder diameter and the number of cylinders. Many of the engine's indicators are closely related to the displacement. Generally speaking, the greater the displacement, the greater the engine output.
