THE FLEXIBLE TYPE FUEL RAIL SYSTEM FOR LPLI VEHICLE

摘要

The present invention relates to a fuel rail structure for an LPG vehicle and, more specifically, to a flexible fuel rail structure for an LPG vehicle, wherein the flexible fuel rail structure has multiple fuel rails. The fuel rails are separately connected to multiple injectors by discharge pipes and suction pipes, so LPG fuel can be smoothly supplied to the injectors, thereby equalizing the supply conditions of the LPG fuel from the first injector to the last injector. When bubbles are generated from the LPG fuel evaporated in one of the injectors, the generated bubbles can be quickly discharged without an effect on the other injectors. The discharge pipes and the suction pipes are made from material which does not react to the LPG fuel, thereby preventing the generation of the bubbles beforehand. The flexible fuel rail structure is flexible to be applied to various vehicles regardless of the kinds of the vehicles and installation spaces in the vehicles.
