Design and simulation of analysis methods for exhaust gas emission parameters of automobile engine
In order to improve the accuracy of vehicle engine exhaust emission pollution parameter control,the car-following exhaust gas test system was used to calculate the vehicle engine exhaust emission factor and simulate the diffusion process.According to the road test direct sampling method,the exhaust emission pollution parameters were tested and calculated accurately,then the point source Gaussian diffusion model was used for simulation analysis,and the CALINE4 mode was adopted to modify the point source Gaussian model for accurate analysis results.The analysis results show that the error between the calculated results of as-proposed method and the actual results of the emission factors is small and kept lower than 0.5 g/km,and the diffusion analysis of the emission factors conforms to the actual situation with high accuracy,indicating that it is conducive to the control of urban traffic pollution and the improvement of atmospheric environment quality.
