Analysis Observations: • For a fixed Pmax, decreasing Pcomp (or increasing Pmax minus Pcomp pressure) results in decreasing NOx. The effect is small at high loads, but stronger at lower loads • The HC emission at high loads (75% and 100%) is not affected by either Pmax or Pcomp variations • CO emissions decrease with increasing Pcomp, i.e. decreasing with higher air/fuel ratio caused by larger air amount trapped in the cylinder at the higher compression pressure • The effect of Pmax and Pcomp on PM (Particulate matter) emission follows the same trend as that of HC emission • Use of the compression pressure influence on NOx emissions, in the MAN B&W NOx function.
