| Abstract: | The catalytic mechanism of electrically heated three way catalyst converter for HEV was analyzed and the control-oriented dynamic model of catalyst converter was created. Then, the operation of the vehicle was simulated. Some factors which can affect the catalytic converter's light-off time, such as electrically heated power capacity and location, were investigated systematically. The simulation was accomlished in NEDC(new European driving cycle).Effects of electrically heated energy for the battery's state of charge, the vehicle's fuel
comsumption and emissions were analyzed. Simulation results show that electrically heated source equipped in HEV can increase the light-off of catalytic converters effectively with tiny price of fuel consumption, improve the HC/CO catalytic efficiency during the period of cold start and depletion of battery can be avoided. |
