In this paper,the application of an innovative palladium-ruthenium catalytic converter in a passenger car is taken as the research object,and the catalytic converter scheme and ECU software are studied,analyzed and optimized to meet the regulatory requirements of the sales region.Under the premise of reducing the emission of gas pollutants,it not only breaks the dependence of the three-way catalytic converter on the use of rhodium,avoids the bottleneck of imported raw materials,but also effectively reduces the cost of the three-way catalytic converter.
