What two strokes have minimal effect when calculating the Mean Effective Pressure (MEP).
A) Intake and exhaust strokes.
B) Intake, compression and exhaust stroke.
C) Exhaust, power and intake strokes.
D) Intake and power strokes.

Question

Quizplus · Accepted Answer

The intake and exhaust strokes have minimal effect on calculating the Mean Effective Pressure (MEP) because MEP is primarily determined by the pressures during the compression and power (combustion) strokes, where the actual work is done. The intake and exhaust strokes involve the movement of air and exhaust gases into and out of the cylinder with relatively low pressure changes compared to the compression and power strokes.
