Cubic Inch Displacement

Capacity/Volume: Automobile Engine Displacement

Piston and cylinder A combustion engine ignites a compressed mixture of fuel and air (containing oxygen O2), in a metal cylinder. The resulting explosion, or expansion of gas, forces the piston to move (ultimately turning the car's wheels through a series of gears, etc.). The piston displacement is found by multiplying the area of the piston head (whose diameter is called the bore ) by the height of the cylinder (i.e., length of the stroke). Basically then, piston displacement is the volume of the cylinder. Engine displacement ( or size ) is the number of cylinders times the displacement of one of the pistons.
