【Abstract】 The development of evaporative emission control technology and the design method of evaporative control system are introduced. The control strategies of this system are presented: purge the fuel vapor inside canister as much as possible, meanwhile, keep air-fuel ratio steady. The automobile test showed that this design method of EVAP System was available, and the evaporative emission standard can be reached.更多还原
