Friction torque can also be an asset in engineering.
2.
"' Friction torque "'is the torque caused by the frictional force that occurs when two objects in contact move.
3.
The true relations of friction torque, engine speed, and air density are much more complex and cannot be deduced from the available information.
4.
Sometimes the term FMEP ( friction mean effective pressure ) is used as an indicator of the mean effective pressure lost to friction ( or friction torque ) and is just the difference between IMEP n and BMEP.
5.
It is known, however, that the friction torque is such that the friction horsepower wdl increase with engine speed raised to between the first and second power, approaching the square of the speed at the higher speeds.
6.
An empirical and approximate statement, applicable to the speed and density ranges herein covered, is that the friction torque ( m . e . p . ) increases as a linear function of speed at Q constant, air density, and as a linear function of air density at a constant speed.
