Matekunas, F A

This patent describes a combustion control for an internal combustion engine of the type having a combustion chamber, a rotating crankshaft, ignition apparatus for the combustion chamber and diluent gas flow control apparatus comprising, in combination: means responsive to combustion chamber pressure to generate signals for a combustion event indicating combustion pressure and motored pressure at a predetermined crankshaft rotational angle when combustion is substantially complete; means effective to compute, from the signals, a final pressure ratio of combustion pressure to motored pressure at the predetermined crankshaft rotational angle when combustion is substantially complete; means effective to adjust the diluent flow to maintain the final pressure ratio at a predetermined level, whereby diluent flow is optimally controlled.
