EVAPORATIVE EMISSION CONTROL IN BATTERY POWERED VEHICLE WITH GASOLINE ENGINE POWERED GENERATOR

摘要

plug-in hybrid electric vehicles (plug-in hybrid vehicle) is an additional battery power provided by the gasoline engine, an electric generator are driven by at least one electric motor that is powered by the system. The canister is connected by a fuel vapor vent passage is used to temporarily adsorb the fuel vapor from the fuel tank of the vehicle during refueling. Further, the canister, the canister and an exhaust for removing the vapor stored in the canister during refueling tank has a first fuel vapor and air flow passage for introducing the ambient air. The canister is provided with a second passage for guiding the air and purged vapor from the canister to the engine to operate. Only the first and second passages during engine operation for purging of the stored fuel vapor is released. The first passage is selectively opened when the tank refueling. The sealed fuel system eliminates the fuel tank vapor generation and canister effluent flowing throughout the day.
