The amount of air taken inside the cylinder of IC engine is dependent on___

The amount of air taken inside the cylinder of IC engine is dependent on___

Option:

a. mechanical efficiency
b. volumetric efficiency
c. thermal efficiency
d. none of the above

Correct Answer : b. volumetric efficiency

Explanation:

The amount of air taken inside the cylinder of an IC engine is dependent on volumetric efficiency. Volumetric efficiency is the ratio of actual volume drawn in the cylinder during suction stroke to the swept volume of the piston. For the normal engine the volumetric efficiency value lies between 70% to 80%. The value of volumetric efficiency can be more than 100% for naturally aspirated engines.
