내연 기관의 성능을 평가하기 위해 피스톤에 작용하는 것으로 가정하는 평균적인 압력.
Mean effective pressure; a theoretical constant pressure that, if acting on a piston during a power stroke, would produce the same net work as actually developed.

"The engineer calculated the MEP to evaluate the performance of the internal combustion engine."
"A higher MEP indicates that the engine is producing more work per unit of displacement."
"Comparing the MEP of different engines allows for a size-independent performance analysis."
