摘要
根据汽车动力学的基本理论,将整车动态行驶参数转换为发动机转速和输出转矩的时间函数,在发动机实验台实现对整车行驶工况的动态模拟。并基于发动机动态实验台进行了整车瞬态排放实验,得到了整车排放因子,并对结果进行了分析对比,为利用发动机动态实验台进行整车排放研究提出了一种切实可行的方法。
The vehicle driving parameters are calculated to engine speed and torque base on the vehicle dynamics and driving model is simulated on engine bench.Vehicle emission test is carried on and emission factor is calculated and analyzed.It is proved that this is a feasible method to study vehicle emission base on the engine bench.
