The computer simulation technology of the work process of internal-combustion engine is the important measure to study the internal-combustion engine, but generally, because of the uncertainty of input parameters, the precision of the simulation model of the engine work process, which largely limits the application of the simulation model, so the parameters of the simulation model needs to be calibrated. Taking the work process of the certain one type turbocharging diesel engine as the example, and combining the genetic algorithm with the ant colony algorithm, the parameter combination which can satisfy the requirements of precision, is selected in this article to effectively reduce the simulation experiment times of parameter calibration, and realize the automatic calibration of the simulation model parameters. By comparing and analyzing the practical result of the experiment and the result of the simulation computation, the effectiveness of the algorithm has been validated in the article. |
