Inspection and Repair of Three-way Catalyst(TWC)in Electronic-controlled Engines
Vehicle exhaust emissions,as the primary source of motor vehicle pollution,have become a serious threat to human health.The three-way catalyst(TWC),as the core device for vehicle exhaust processing,can effectively control vehicle exhaust emissions and achieve the intended environmental objectives.Based on the e-lectronic-controlled engine,the operating principles and common malfunctions of TWC have been analyzed in this paper.Four diagnostic schemes are provided to evaluate the performance of TWC,and corresponding vehicle ma-intenance strategies are given.
