Description
Technical field
The present invention relates to LNG passenger vehicle fuel gas pipeline structure, the invention still further relates to LNG passenger vehicle.
Background technology
The routine of LNG passenger vehicle fuel gas pipeline assembly is arranged and is: before gas cylinder is arranged in trailing wheel, carburetter, expansion tank are structure as a whole and after being arranged in trailing wheel, gas cylinder distance carburetter, expansion tank about 2 meters, close together, all meets operating needs for gas cylinder feed flow and to driving engine air feed, but for the Large LNG passenger vehicle of more than 12 meters, driving engine is generally positioned at rear vehicle, consider car load axle load distribution equilibrium, gas cylinder is generally arranged in inside front-wheel rear boot, the gas flow of needs is accelerated in order to meet motor instant, prevent driving engine for unsaturated vapor, expansion tank and carburetter are integrally arranged in driving engine side, but this arrangement distance of nearly more than 6 meters between gas cylinder to carburetter, what circulate inside this section of pipeline is cryogenic liquid, the LNG liquid flowed out from gas cylinder is generally-162 degrees Celsius, longer cryogenic liquid pipeline can frosting at ambient temperature, freeze, low-temperature condition affects the pipeline life-span, and condensed water can drip to the boot compartment interior damage kinds of goods below vehicle frame after freezing.
Summary of the invention
The object of the present invention is to provide LNG passenger vehicle, to solve the pipeline frosting caused because carburetter and gas cylinder spacing are far away, icing problem in prior art, the present invention simultaneously also provides LNG passenger vehicle fuel gas pipeline structure.
In order to solve the problem, LNG passenger vehicle of the present invention, comprise the LNG passenger vehicle fuel gas pipeline structure of the driving engine being located at vehicle frame rear portion, the gas cylinder being located at vehicle frame front portion and connecting engine and gas cylinder, this LNG passenger vehicle fuel gas pipeline structure is included in the carburetter and expansion tank that on vehicle frame, split is arranged, described carburetter next-door neighbour gas cylinder is arranged, described expansion tank is close to described driving engine and arranges, and the air extractor duct of described carburetter is connected by air delivering pipeline with the admission port of described expansion tank.
Described carburetter is between passenger vehicle front-wheel and described gas cylinder or be positioned at the side of described gas cylinder away from passenger vehicle front-wheel.
Described expansion tank is positioned at the rear of passenger vehicle trailing wheel.
LNG passenger vehicle fuel gas pipeline structure, this LNG passenger vehicle fuel gas pipeline structure is included in the carburetter and expansion tank that on vehicle frame, split is arranged, described carburetter next-door neighbour gas cylinder is arranged, described expansion tank is close to described driving engine and arranges, and the air extractor duct of described carburetter is connected by air delivering pipeline with the admission port of described expansion tank.
Described carburetter is between passenger vehicle front-wheel and described gas cylinder or be positioned at the side of described gas cylinder away from passenger vehicle front-wheel.
Described expansion tank is positioned at the rear of passenger vehicle trailing wheel.
Carburetter and expansion tank split arrange by the present invention, expansion tank next-door neighbour driving engine is arranged, to meet the gas flow that motor instant accelerates needs, carburetter next-door neighbour gas cylinder is arranged, connecting line between carburetter with gas cylinder is just shorter, the liquid that gas cylinder flows out flows in carburetter very soon and vaporizes, and gas pipe line is not easy frosting, freezes, solve in prior art due to carburetter and gas cylinder spacing far and the pipeline frosting caused, icing problem.
