Can someone tell me what the abbreviations mean in the "calculated power and engine pressures table">>> "IMEP" "FMEP" "BMEP" stand for.

Thanks

Brake Mean Effective Pressure (bmep): A theoretical average pressure that would have to be present in each cylinder during the power stroke to reproduce the force on the crankshaft measured by the absorber (brake) on a dynamometer. The bmep present during the power stroke would produce the same power generated by the varying pressures in the cylinder throughout the entire four-cycle process.

Friction Mean Effective Pressure (Fmep): A theoretical average pressure that would have to be present in each cylinder during the power stroke to overcome the power consumed by friction within the engine. Fmep is usually calculated by first determining the Indicated Mean Effective Pressure (Imep): the maximum horsepower that can be produced from the recorded cylinder pressures. The Brake Mean Effective Pressure (Bmep) is then measured by performing a traditional "dyno" test. The Fmep is calculated by finding the difference between the Imep and the Bmep: Fmep = Imep - Bmep. Fmep can also be directly measured with a motoring (electric) dyno.

Indicated Mean Effective Pressure (Imep): A theoretical average pressure that would have to be present in each cylinder during the power stroke to generate the maximum horsepower possible from the pressures recorded within the cylinder of an engine during an actual dyno test. The Imep pressure assumes that the recorded pressures within the test engine will be entirely converted into motive force (with no losses due to friction).
