volumetric efficiency
volumetric efficiency n 1. (General Engineering) the ratio of fluid delivered by a piston or ram pump per stroke to the displacement volume of the piston or ram 2. (Automotive Engineering) the ratio of air or gas-air mixture drawn into the cylinder of an internal-combustion engine to the volumetric displacement of the piston volumetric efficiency
volumetric efficiency[¦väl·yə¦me·trik i′fish·ən·sē] (mechanical engineering) In describing an engine or gas compressor, the ratio of volume of working substance actually admitted, measured at a specified temperature and pressure, to the full piston displacement volume; for a liquid-fuel engine, such as a diesel engine, volumetric efficiency is the ratio of the volume of air drawn into a cylinder to the piston displacement.
