Specifically, the volumetric efficiency is the ratio (or percentage) of the volume of air which the cylinder/s collect during the suction stroke compared to the volume of the cylinder/s. A general rule of thumb is a ve number of 75 percent or higher is acceptable, but this number will vary with different engine applications.

When iat reads in °c, the pid will have to be converted to °f. Ve is a ratio of actual engine breathing volume to displacement. The bottom of this chart (x axis) represents the “volumetric efficiency”—expressed on the chart as a percent. Volumetric efficiency (ve) definition & description volumetric efficiency (ve) is the actual amount of air flowing through an engine, compared to its theoretical maximum.
