Technician A says that the exhaust valve is larger than the intake valve to ensure that all the exhaust gases leave the cylinder. Technician B says that the exhaust valve is larger than the intake valve to ensure proper heat dissipation. Who is right

Explanation:

Both are wrong.

The larger valve of an engine is the intake valve whereas the smaller one is the exhaust valve.

This is so because engine needs air and fuel in much greater volume than the volume of air exhausted. This increases the efficiency and poweroutput of the Engine.

In this question, both the technicians said that the exhaust valve is larger. So, obviously both of them made a wrong statement.
