The average pressure exerted on a piston during each power stroke is termed_______________.
AI Explanation
The correct answer is B) mean effective pressure.
The mean effective pressure (MEP) is the average pressure exerted on a piston during each power stroke. It is a calculated value that takes into account the pressure variations throughout the cycle and provides a single representative pressure value. This is an important parameter used in the analysis and performance evaluation of internal combustion engines.
The other options are incorrect:
A) Indicated horsepower is a measure of an engine's power output, not the average pressure.
C) Exhaust back pressure refers to the pressure in the exhaust system, not the pressure on the piston.
D) Compression pressure is the pressure during the compression stroke, not the power stroke.
