Abstract:
1. A high-pressure direct injected gaseous fuel system, comprising: a fuel tank capable of storing fuel at a first pressure; a compressor comprising an inlet capable of receiving the fuel, and operative to supply, at an outlet, the fuel at a second pressure higher than the first pressure; an accumulator in fluid communication with the outlet to receive and to store the compressed gaseous fuel from the compressor and in fluid communication with the inlet through a pressure regulator to convey excess compressed gaseous fuel to the compressor; a pressure relief valve interconnecting the fuel tank and the outlet, and operative to allow fuel flow between the fuel tank and outlet if the second pressure exceeds a threshold pressure; and a plurality of injectors connected to the accumulator, wherein the injectors are adapted to inject the fuel directly into a combustion chamber.
