ABSTRACT:
A combustion pressure responsive transducer energizes a solenoid valve assembly which varies an induction passage pressure signal to control a pressure responsive servomotor. The servomotor regulates a combustion parameter to limit peak combustion pressure to a selected value during subsequent combustion events and thus inhibit the formation and emission of oxides of nitrogen. In one embodiment the servomotor regulates the ignition timing, while in a second embodiment the servomotor regulates exhaust gas recirculation.
