Simulation of the Influence of Vehicle Catalysts with Specific Physical Parameters on Emission Characteristics

目前国Ⅵ排放法规已逐步实施,乘用汽油车和柴油车均面临着严格的排放限值要求。利用CHEMKIN软件,构建了使用特定物性参数车用催化器的车用醇基汽油合成燃料氧化反应的化学反应动力学模型。利用该模型对目前车用醇基汽油合成燃料的排放特性进行模拟计算,仿真结果与试验数据较为吻合,证明了该仿真模型的正确性。该研究对掌握车用催化器对车辆排放性能的影响有着重要的指导意义。

At present, China's VI emission regulations have been gradually implemented, passenger gasoline vehicles and diesel vehicles are facing stringent emission limits requirements. Using CHEMKIN software, a chemical reaction kinetics model for the oxidation reaction of alcohol -based gasoline synthetic fuels using a specific physical parameter vehicle catalytic converter is established. The model is used to simulate the emission characteristics of alcohol-based gasoline synthetic fuels for vehicles.The simulation results are in good agreement with the experimental data, which proves the correctness of the simulation model.This research has important guiding significance for mastering the influence of vehicle catalytic converter on vehicle emission performance.
