APPARATUS FOR DETECTING FUEL PRESSURE OF BI FUEL CAR

摘要

A fuel pressure detecting system of a bi-fuel vehicle is provided to reduce the distance between the gas injector and the pressure sensor, thereby measuring accurate fuel pressure supplied to the gas injector quickly. A fuel pressure detecting system of a bi-fuel vehicle comprises a gas injector, a gasoline engine control unit, a pressure sensor(55), and a pressure sensor fixing member(59). The gas injector reduces the pressure of gas fuel compressed in a fuel tank and then sprays it. The gasoline engine control unit drives an engine with the decompressed gas fuel. The pressure sensor includes a sensing part measuring fuel pressure supplied to gas injectors, and a fuel pressure signal generating part with a plurality of I/O ports to convert the measured fuel pressure into electric signal and transmit it to the gasoline engine control unit. The pressure sensor fixing member fixes the pressure sensor to an outside bracket of a fuel rail(53) supplying gas fuel to each gas injector.
