STUDY ON THE DETERMINATION OF THE HEAT RELEASE RATE OF DIESEL ENGINE BY THE METHOD OF PARAMETER ESTIMATION

Abstract

Abstract: A method of parameter estimation is proposed for the determination of heat release rate of the dual-Weiber function of diesel engine by the performance parameters measured of the diesel engine. This method determines the constants in the dual-Weiber function by making the closest between the measure data and model predictions. For the character of the nonlinear multi-parameter optimization problem, the method of simulated annealing, downhill simplex and uniform design are used to solve this problem. Example studies show that the results are satisfactory.

Key words: Diesel engine, Heat release rate, Parameter estimation
