It is the ratio of the quantity of the air taken inside the cylinder to the stroke volume.
> Bumping Clearance
Increase in bumping clearance leads drop in volumetric efficiency. Clearance can be rectified by changing cylinder head gasket with different thickness gasket
> Valves are leaking.
Leaking valves also leads to drop in volumetric efficiency. Overhaul or change the valves with new one
> Piston rings are leaking.
Damaged piston rings also decrease the volumetric efficiency
> Liner worn out.
Because of worn out liner air blow pass to the crank case and leads to decrease in volumetric efficiency.
Volumetric Efficiency= Volume of the air taken/Stroke Volume

A compressor’s volumetric efficiency (V) is defined by the ratio of actual volume of gas that it could suck if there was no such thing as clearance volume. Therefore, a compressor with less clearance volume should be more volumetrically efficient.It is very important factor to consider for proper work and maintaining of compressor efficiency. I appreciate that you addressed this topic here and explained.
