Mean Effective Pressure - Types of Mean Effective Pressures

Types of Mean Effective Pressures

Mean effective pressure (MEP) is defined by the location measurement and method of calculation, some commonly used MEPs are given here.

  • Brake mean effective pressure (BMEP) - Mean effective pressure calculated from brake power
  • Indicated mean effective pressure (IMEP) - Mean effective pressure calculated from in cylinder pressure, average in cylinder pressure over engine cycle (720° in a 4 stroke, 360° in a 2 stroke).
  • Friction mean effective pressure (FMEP) - Theoretical mean effective pressure required to over come engine friction, can be thought of as mean effective pressure lost due to friction. BMEP = IMEP - FMEP

Famous quotes containing the words types of, types, effective and/or pressures:

    “... there are two types of happiness and I have chosen that of the murderers. For I am happy. There was a time when I thought I had reached the limit of distress. Beyond that limit, there is a sterile and magnificent happiness.”
    —Albert Camus (1913–1960)

    “The bourgeoisie loves so-called “positive” types and novels with happy endings since they lull one into thinking that it is fine to simultaneously acquire capital and maintain one’s innocence, to be a beast and still be happy.”
    —Anton Pavlovich Chekhov (1860–1904)

    “They [women] can use their abilities to support each other, even as they develop more effective and appropriate ways of dealing with power.... Women do not need to diminish other women ... [they] need the power to advance their own development, but they do not “need” the power to limit the development of others.”
    —Jean Baker Miller (20th century)

    “Today’s pressures on middle-class children to grow up fast begin in early childhood. Chief among them is the pressure for early intellectual attainment, deriving from a changed perception of precocity. Several decades ago precocity was looked upon with great suspicion. The child prodigy, it was thought, turned out to be a neurotic adult; thus the phrase “early ripe, early rot!””
    —David Elkind (20th century)
