Question

a decrease in expansion stroke work transfer result in actual engine due to

Answer 1

Answer:

Explanation:

A decrease in expansion-stroke work transfer results. > Pumping work is the difference between the work done in expelling the gases (during exhaust stroke) and the work done in inducing the fresh charge (during suction stroke). The loss is due to the pumping gases from low inlet pressure to high exhaust pressure

Answer 2

Answer:A decrease in expansion-stroke work transfer results. > Pumping work is the difference between the work done in expelling the gases (during exhaust stroke) and the work done in inducing the fresh charge (during suction stroke). The loss is due to the pumping gases from low inlet pressure to high exhaust pressure.
