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
for E5B15 and diesel fuel.

, and less than the 8 CAD advance with 20% EGR reported by Hoepke et al.
Perhaps the remarkable thing about the S2000 engine's output is not obvious in horsepower or BMEP
Biocomponents have a negative effect on fuel consumption and BMEP
Comparison of BSFC at 1200 and 1600 rpm at different BMEP

For this study, the operating point at 2000 rpm and BMEP
= 5 bar was chosen.
