Q. The mean effective pressure obtained from engine indicator indicates the

A
Maximum pressure developed
B
Minimum pressure
C
Instantaneous pressure at any instant
D
Average pressure
Solution:
  • Mean effective pressure is the engines capacity to do work independent of engine displacement.
  • So it is average pressure acting on a piston during the cycle.
  • The Mean Effective Pressure (MEP) is a theoretical parameter used to measure the performance of an internal combustion engine (ICE).
