Exhaust is an assumed constant pressure process like suction. So, the answer should be option A.

Mani said:   7 years ago
During exhaust, Pressure must be greater than the atmospheric pressure unless leakage of air will take place and hence it will decrease the efficiency.

It is equal, the valves exhaust stroke is opened and piston pushes gases to ATM at ATM pressure only.

In compression, stroke pressure is more than atmosphere pressure.

Akki said:   9 years ago
It should be lower because while suction stroke volume increase suddenly.
