Analytical methods to provide a guideline for predicting the limit for acceptable power output of dual fuel engines due to the onset of autoignition and knock are described. This is achieved primarily through improved modeling of the chemical reaction rates of the charge during compression and subsequently following pilot ignition. Some performance results with methane as a fuel are presented.
