ABSTRACT:
A control for an internal combustion engine by pressure ratio management. The ratio of combustion chamber pressure to motored pressure is determined for several predetermined crankshaft rotational angles. These pressure ratios are used to control ignition timing for MBT, diluent gas flow rate (EGR) and fuel balance among combustion chambers. The control requires from three to five pressure samples for each combustion event, depending on sensor and control options. The pressure sensors need not sense absolute pressure if they are linear and do not change gain or bias significantly during one cycle.
