ABSTRACT:
An improved feedback control system and method for internal combustion engines that permits extremely accurate feedback control. This is done by utilizing a sensor device that is interrelated with the combustion chambers of the engine so that it only samples the gases from the engine at a time after the exhaust port has opened and before any fresh air charge enters the combustion chamber. By doing this, it is possible to ensure that only combustion product reach the sensor and the sensor chamber will have a time to purge itself of the combustion products from one cylinder before another sampling takes place. This is described in conjunction with both two and four-cycle engines.
