【Abstract】 The paper gives the constitution of the tail gas exhausted by automobile,and the defaults caused by it as well.And then,it emphasizes on the purring and muffing mechanism,and several means are provided,especially the effect of catalyst.As far as muffing is concerned,it includes resistant and blocking and their combination.And purifier includes thermal reactor?auxiliary air injection?grain filter?container for catalytic conversion and so on.Based on what was given before,primarily the combination of the principle of injection-convection and catalytic conversion method,one new sample is design concretely and systematically.更多还原
