The ratio of the volume of fluid actually displaced by a piston or plunger to its swept volume.
容积效率
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.
