Volume displaced by each piston moving from bottom dead center to top dead center multiplied by the number of cylinders.

Engine Displacement


the total working volume of the cylinders in an internal combustion engine. The working volume of one cylinder is equal to the product of the cross-sectional area of one cylinder multiplied by the piston stroke. The engine displacement is one of the features characterizing the power rating of an engine. The engine displacement is usually measured in liters (cu decimeters), but, in engines of small working volumes, the displacement is frequently measured in cu cm (for example, in motorcycle engines).
