|Volumetric efficiency = (Swept volume/(clearance volume+swept volume)), swept volume is volume swept by piston in cylinder.
Clarence volume is about only 10-15% of total volume. So volumetric efficiency of engine could be more than 70%.

|Voletric efficiency=Vas/Vs, Vas-actual suction of air between top dead center to bottom dead center.
Vs-Vas+clearance volume. Clearance volume = 0.1 to 0.15.

|It is the ratio of an actual amount of air sucked to the total volume of a reciprocating cylinder.|
|Suraj Kumar said: (Sep 29, 2018)|
|It is ratio of effective swept volume to the swept volume.|

|Volumetric efficiency is the ratio of the volume of free air delivery per stroke to the swept volume of the piston.|
