The effect of high pressure relief device 2 is the low-pressure fuel gas the high pressure air reducing of 20MPa to 1.6MPa, gas decompression
During need to absorb substantial amounts of heat, therefore the temperature of low-pressure fuel gas can be very low, and needing to carry out it heating could meet
Engine gas intake air temperature demand.Before extremely frigid zones starts vehicle, first heater 5, by heater 5 work
Heat up to environment in compartment, heated engine 3 water route；In compartment during proper temperature, the effect of heater 5 is to maintain car
Temperature in railway carriage or compartment；Now, starting engine 3, engine 3 outlet pipeline is divided into two-way by the first threeway 7, and a road is to high pressure relief
Device 2, carries out initial stage preheating to just post-decompression low-pressure fuel gas, another road to heat exchanger 4, by heat exchanger 4 again to send out
Combustion gas before motivation gas inlet is heated again, meeting the demand of engine gas intake air temperature, thus realizes extremely frigid zones
The startup of engine and normally using.
Embodiment described above is only to be described the preferred embodiment of the present invention, the not model to the present invention
Enclose and be defined, on the premise of designing spirit without departing from the present invention, the technical side to the present invention for the those of ordinary skill in the art
Case make various deformation and improve, all should fall into claims of the present invention determine protection domain in.
