The real-time combustion model is capable of simulating the HRR (heat release rate) and in-cylinder pressure, along with the related metrics, such as MFB50, PFP (Peak Firing Pressure), IMEP (Indicated Mean Effective Pressure) and BMEP
Tests have been run in steady state conditions at 2000 rpm and BMEP
= 3 bar.
Figure 6 shows the fuel consumption versus engine BMEP

Perhaps the remarkable thing about the S2000 engine's output is not obvious in horsepower or BMEP
, Brake Mean Effective Pressure is a quantity used by engineers to compare the performance of different internal combustion engines.
Biocomponents have a negative effect on fuel consumption and BMEP

For this study, the operating point at 2000 rpm and BMEP
