冷起动和暖机时减少排放物的研究

Study of Reducing Emissions During Cold Starting and Warm-up

针对汽车冷起动排放的问题 ,论述了提高催化转化器入口温度和控制空燃比 ,它们能够缩短暖机时间 ,减少排放物 ,并且该论文还提出了提高入口温度的方法。

As for the problem of cold starting emission of a motor vehicle, the paper states the increase of the catalytic converter intake temperature and the control of air and fuel ratio. They can shorten warming up the time, reduce emissions, and the paper put forward the methods of increasing intake temperature.
