Effects of exhaust parameters on temperature and pressure drop of the gasoline particulate filter in the regeneration equilibrium state

Abstract In order to investigate the exhaust parameters how to influence the particulate purification performance of the gasoline particulate filter (GPF), the importance of exhaust parameters on the temperature and pressure drop in the regeneration equilibrium state of the gasoline particulate filter is studied by using the numerical simulation software FLUENT. The distribution law of optimal temperature in the regeneration equilibrium state and pressure growth rate of the gasoline particulate filter under different exhaust parameters is analyzed, and the numerical simulation results are compared with the experimental values of the literature to verify the accuracy of the numerical research. The main results are presented as follows: (1) The temperature and pressure drop in the regeneration equilibrium state is decreased by 2.1% and 6.4% when α value is increased from 4 to 8, respectively. (2) The temperature and pressure drop in the regeneration equilibrium state is increased by 2.7% and 26.5% when the exhaust temperature is increased from 400 K to 500 K, respectively. (3) The temperature in the regeneration equilibrium state is increased by 2.5%, and the pressure drop is increased by 12.3 times when the exhaust flow rate is increased from 0.001 kg/s to 0.01 kg/s. Finally, the results of the orthogonal experiment show that the exhaust temperature has the most significant influence on the temperature in the regeneration equilibrium state, and the exhaust flow rate has the most significant impact on the pressure drop in the regeneration equilibrium state.
