Brake mean effective pressure (BMEP) is calculated from measured dynamometer torque. Net indicated mean effective pressure (IMEP) is calculated using the indicated power; i.e., the pressure volume integral in the work per cycle equation. Sometimes the term FMEP (friction mean effective pressure) is used as an indicator of the mean effective ...
A compressor map is a chart which shows the performance of a turbomachinery compressor.This type of compressor is used in gas turbine engines, for supercharging reciprocating engines and for industrial processes, where it is known as a dynamic compressor.
A BMEP of 238 puts it close to the limit for a naturally aspirated gas-burning engine. Naturally aspirated Formula One engines typically achieved BMEP values of 220 psi. Cam profiles, engine RPM , engine height constraints and other limitations contribute to the difference in engine power with the Ford unit as well, but the difference in port ...
To calculate the actual efficiency of an engine requires the energy density of the fuel being used. Different fuels have different energy densities defined by the fuel's heating value. The lower heating value (LHV) is used for internal-combustion-engine-efficiency calculations because the heat at temperatures below 150 °C (300 °F) cannot be ...
So in that sense, BMEP acts like a "specific torque", a torque per unit displacement. If we keep the displacement the same and increase the BMEP through other improvements to the engine (higher compression ratio, better breathing, forced induction, etc.), we should get an engine with more torque.
It's a tougher calculation for Democrats in swing districts or those facing tough reelections, especially because many expect one of Trump's first actions on Inauguration Day will be pardoning the ...

Engine designers use expressions other than horsepower to denote objective targets or performance, such as brake mean effective pressure (BMEP). This is a coefficient of theoretical brake horsepower and cylinder pressures during combustion.
