    摘要: A methodology of computing a combustion stability value and using the combustion stability value to control engine operation is provided. The combustion stability value is determined by monitoring engine operation. The combustion stability value is compared to an expected combustion stability value. Where the combustion stability value is greater than the expected combustion stability value, combustion of the internal combustion engine is controlled as a function of the combustion stability value. Where the combustion stability value is not greater than the expected combustion stability value, combustion of the internal combustion engine is controlled as a function of an O2 sensor value. In either case, engine control is accomplished by modifying a target fuel injection value.
