Measurement of IMEP
Measurement of IMEP
(OP)
Hi
Are there any good ways to measure IMEP in a IC engine apart from
1. in cylinder pressure sensors.
2. using a willen line.
Also does any body know of any good site to get info on measuring IMEP. Thanks.

RE: Measurement of IMEP
If you can measure torque, you can compute brake mean effective pressure (BMEP). If you then know or have a correlation for friction MEP (FMEP), then
NIMEP = BMEP + FMEP
I do believe the Heywood text and others have some empirical correlations for FMEP, which is primarily a function of engine speed for a given engine.
