Vehicle emission affect factors analysis and optimizations

本文对影响车辆排放的因素进行了分析和优化,目的是为了减少有害物的排放,从车辆的启动、暖机、排放闭环控制、车辆过渡工况和催化剂加热五个方面讨论了影响车辆排放性能的因素,并就这五个方面提出了相应的优化建议。

For reducing exhaust pollution, this paper talks about some factors and their optimizations which effect in vehicle emission. Those factors are vehicle start, engine warm up , emission close loop control, vehicle blending cycle and catalyst heating and so on, and the paper give suggestion about the factors.
