Definition of volumetric efficiency in English: volumetric efficiencynoun The ratio of the volume of fluid actually displaced by a piston or plunger to its swept volume. Example sentencesExamples - It becomes a four-cylinder engine running at a more open throttle condition, improving volumetric efficiency and reducing pumping losses, with very little loss in the system.
- The diesels will require better volumetric efficiency in order to achieve more complete combustion, thereby reducing emissions.
- The all-aluminum head has a pent-roof combustion chamber with a long narrow 21.5 inch included angle to improve volumetric efficiency.
- Thanks in part to the advent of electronic controls, engineers are trimming losses, perfecting combustion, boosting volumetric efficiency and raising redlines.
