Abstract:
An internal combustion engine operable in a premixed charge compression ignition mode, comprising:an engine body;a combustion chamber formed in the engine body for containing a mixture of fuel and air;combustion history control means for controlling a combustion history of future combustion events to optimize engine operation, said combustion history control means including at least one of a temperature control means for varying the temperature of the mixture of fuel and air, a pressure control means for ultimately varying the pressure of the mixture, an equivalence ratio control means for varying an equivalence ratio of the mixture and a mixture autoignition property control means for varying an autoignition property of the mixture;engine operating condition detecting means for detecting an engine operating condition indicative of the combustion history and generating an engine operating condition signal indicative of said engine operating condition; andprocessing means for receiving said engine operating condition signal, determining a combustion history value based on said engine operating condition signal, and generating one or more control signals based on said combustion history value, said one or more control signals controlling at least one of said temperature control means, said pressure control means, said equivalence ratio control means and said mixture autoignition property control means to variably control the combustion history of future combustion events.
