VERBRENNUNGSMOTOR UND STEUERANORDNUNG DAFÜR

摘要

An internal combustion engine is provided with a control arrangement for influencing exhaust gas pressures and the level of In-Cylinder-Charge-Dilution (ICCD) so as to provide cycles with different emission characteristics. The exhaust gas pressure may be influenced by adjusting a combustion parameter between various cycles. The adjustment of the combustion parameter may for example include an adjustment of the injection timing, a change in shot mode or a change in fuel quantity. By making such adjustments cycle-to-cycle exhaust gas pressure variations may be introduced so as to influence future combustion events and reduce overall emissions and noise levels.
