摘要：

Using AMESim to build a three-way catalytic converter (TWC) physical model to study the light off characteristics, through numerical solution of the energy and mass conservation quations of gas-solid two phase. This paper obtains the emissions conversion rate curve, such as CO, unburned hydrocarbons (CaHb) and nitrogen oxides (NOx) under different parameters. The results show that, the engine control strategy, allocation of TWC and it's structure are all the TWC light off characteristics effects, which provids the theory basis for the TWC designers.
