FUEL SYSTEM AND METHOD

摘要

A f?el system and method of controlling the fuel system in an engine using a liquid propane fuel wherein a fluid pressure control module (11) having a housing (12) and plurality of solenoids (20) are provided for venting the fuel pressure in the fuel rails of the fuel system after shut down of the vehicle to reduce fuel leakage from the fuel injectors and fuel rail by having a fuel bleed (2OB) solenoid vent the fuel pressure in the fuel rail to an evaporative emissions canister, while other solenoids (2OR, 2OF and 20S) are shut, to further eliminate evaporative fuel emissions from the vehicle during engine shut down.
