HIGH PRESSURE DIRECT INJECTED GASEOUS FUEL SYSTEM AND RETROFIT KIT INCORPORATING THE SAME

摘要

A high-pressure direct injected gaseous fuel system comprising a fuel tank capable of storing fuel at a first pressure and a compressor including an inlet capable of receiving the fuel, and operative to supply, at an outlet, compressed fuel at a second pressure higher than the first. The system also includes an accumulator connected to the outlet and a plurality of injectors connected to the accumulator. The injectors are adapted to inject fuel directly into a combustion chamber. The system includes a pressure relief valve interconnecting the fuel tank and the outlet, wherein the pressure relief valve is operative to allow fuel flow between the fuel tank and outlet if the second pressure exceeds a threshold pressure.
