Volumetric efficiency (VE) in internal combustion engine engineering is defined as the ratio of the equivalent volume of the fresh air drawn into the cylinder during the intake stroke (if the gases were at the reference condition for density) to the volume of the cylinder itself. The term is also used in other engineering contexts, such as hydraulic pumps and electronic components.[1][2][3][4]
