FUEL PRESSURE CONTROL STRATEGY AT ENGINE SHUTDOWN |
摘要 |
A fuel system control method may include determining when an engine transitions from an engine on condition to an engine off condition. The method further includes determining a first fuel pressure in a fuel system of the engine a predetermined time after the determined engine off condition. A fuel injector of the fuel system may be actuated during the engine off condition when the first determined fuel pressure is above a first predetermined pressure limit to bleed fuel from the fuel system and reduce pressure within the fuel system.
