Volumetric efficiency is a measure of how effectively an internal combustion engine can draw in and utilize air during the intake stroke. It is an important factor in engine performance and can be affected by a number of factors such as engine design, atmospheric conditions, and operating conditions. This volumetric efficiency calculator can help you determine the efficiency of an engine and identify areas for improvement!
