整车装配微粒捕集器后，会对其性能产生影响，文中进行柴油机微粒捕集器与整车匹配研究．利用GT‐Suite软件，建立发动机仿真模型，并与试验结果进行比对，二者误差在5％以内．建立发动机与微粒捕集器耦合模型，微粒捕集器捕集系数最高达到90％，但使发动机动力性、经济性有所下降．建立整车联合仿真模型，仿真结果表明，最高车速下降7．2％，0～100 km／h加速时间增加13．7％，最大爬坡度下降4．8％．在N EDC工况中，100 km油耗增加3．7％，但微粒物的排放量从0．57 g／km下降到0．031 g／km ，满足国IV排放标准．

Assembling vehicle with a DPF will weaken its performance ,so that this paper made a matc‐hing research of DPF and vehicle . An engine simulation model is established based on GT‐suite , whose error was within 5% compared to experiment ;A simulation model is established combined the engine and DPF ,that trap capture coefficient was up to 90% ,but the power performance and fuel e‐conomy declined .Joint vehicle simulation model is established ,whose results showed the vehicle’s top speed decreased 7 .2% ,0~100 km/h acceleration time increased 13 .7% ,maximum grade climb‐ing ability decreased 4 .8% and fuel consumption increased 3 .7% in NEDC working condition ,while particulate matter emissions of vehicle dropped to 0 .031 g/km from 0 .570 g/km ,w hich met the Stage IV emission standard .
