Webb1 mars 2005 · Friction mean effective pressure (FMEP) is based on the difference between IMEP and BMEP, and represents the mechanical losses within the engine. 2.3. Ricardo 8-mode FTP simulation For estimates of fuel savings to be useful, they need to be representative of what can be achieved in real-world operation. WebbPiston ring friction losses account for approximately 20% of the total mechanical losses in modern internal combustion engines. A reduction in piston ring friction would therefore …
The effect of cylinder liner operating temperature on frictional loss …
WebbThe friction contribution (FMEP) of the simulation and measurement match very well. The detailed examination of the crank angle resolved friction forces shows excellent correlation for the hydrodynamic, and boundary lubrication regions. This research proves that the friction behavior of a PCU with honed surfaces can be simulated properly.
