Simulating Analysis of Methanol Combustion Process and Variations of Cycle to Cycle in Diesel Engine

A zero-dimension combustion model suitable to multi-fuel combustion process has been developed and successfully used in the analysis of methanol combustion process The V_2b function is calculated with the Powell Optimized Algorithm. The concerned characteristics include in the variables of zero-dimension model, mean indication pressure, maximum combustion pressure, ignition delay and the correlation coefficient between heat release rate and ignition delay. The heat release rate curves on different conditions are fitted and the statistic analyses of the cyclic variations are conducted.
