Description
Technical field
The utility model belongs to engine art, particularly relates to a kind of gas-fueled vehicles.
Background technique
21 century, facing mankind the threat of the problems such as energy shortage, environmental deterioration, urban population expansion, and these problems are all closely bound up with the automotive industry of fast development, and China's pollution of atmosphere situation is quite serious.The atmosphere environment supervision result of 660 big and medium-sized cities, the whole nation shows, what atmosphere quality reached national standard reference only has 1%, and wherein waste gas sent off from automobiles is the major reason of urban atmospheric pollution.
In order to meet economic development needs, uplift the people's living standard and protection of the environment, China vigorously promotes the use rock gas." plan of the project such as West-east Gas, " Russian gas supplying the South " and " LNG introduction " and enforcement, for many cities can create condition with rock gas.Rock gas has all been admitted in most cities, and the city in national air feed planning is energetically for the arrival of rock gas is prepared, and the city not in planning is also wished with rock gas.
Model utility content
The utility model provides a kind of structure simple for this reason, good mixing effect, gas-fueled vehicles.
A kind of gas-fueled vehicles, comprise liquified petroleum gas cylinder, vaporizer, automatically controlled pressure governor, mixer, ECU and motor; Described liquified natural gas is stored in liquified petroleum gas cylinder, and liquified petroleum gas cylinder outlet is connected with vaporizer, and vaporizer outlets is connected with mixer by automatically controlled pressure governor, and mixer outlet is connected with motor; Described ECU is connected with automatically controlled pressure governor, electric heating wire and motor; Described mixer comprise multiple fuel combination input channel 21,22, multiple fuel pipe 101,102 and shared air chamber 12; Each fuel combination input channel 21,22 communicates with corresponding cylinder; One end of every root fuel pipe 101,102 is connected with corresponding fuel combination input channel 21,22, and the other end of fuel pipe 101,102 extends to shared air chamber 12; Share air chamber 12 to be connected with fuel inlet pipe 13, for receiving the vaporized fuel of input.
The beneficial effects of the utility model are: compressed natural gas automobile exhaust emissions performance is compared with gasoline, diesel-oil vehicle, and harmful body discharge amount of gas-fueled vehicles reduces about 85%, is called as real environmentally friendly vehicle; The mixed effect of rock gas and air is better.
Accompanying drawing explanation
In order to be illustrated more clearly in model utility embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the utility model gas-fueled vehicles structural representations;
Fig. 2 is the structural representation of the utility model mixer.
Embodiment
Be described in detail below in conjunction with the preferred embodiment of accompanying drawing to model utility, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining made to protection domain of the present utility model.
Refer to Fig. 1, a kind of LNGV (liquefied natural gas vehicle), comprise liquified petroleum gas cylinder, vaporizer, automatically controlled pressure governor, mixer and motor; Described liquified natural gas is stored in liquified petroleum gas cylinder, and liquified petroleum gas cylinder outlet is connected with vaporizer, and vaporizer outlets is connected with mixer by automatically controlled pressure governor, and mixer outlet is connected with motor; The cooling water of motor heats vaporizer; Described automatically controlled pressure governor outlet distance mixer suction port is less than 500mm.Described liquified petroleum gas cylinder operating temperature is about subzero 160 degrees Celsius.ECU is connected with motor and automatically controlled pressure governor, electric heating wire, ECU is used for regulating by controlling automatically controlled pressure governor the pressure entering the gaseous natural gas of mixer, ECU is also heated the rock gas after vaporizer gasification by electric heating wire, and ECU is also for controlling normal working of engine.
As shown in Figure 2, mixer main body 1, mixer main body 1 inside has two fuel combination input channels 21 and 22.Two input channels 21 and 22 are connected respectively to the intake section of two cylinders of the gas engine with two cylinders.One air cleaner is installed to the side, upstream of input channel 21 and 22.Mixer main body 1 is provided with vaporized fuel pipe 101 and 102, and the lower end of vaporized fuel pipe 101 and 102 extend in air chamber 12 below mixer main body 1, and the entrance of fuel pipe 101 and 102 is provided with fuel injector 11.Fuel pipe 101 and 102 is connected to the public air chamber 12 below mixer main body 1, the bottom of air chamber 12 be a fuel inlet pipe 13, the vaporized fuel of the adjusted pressure supplied from supplying gaseous fuel device 14 is supplied to air chamber 12 by this inlet pipe 13.During the induction stroke of each cylinder, corresponding input channel is flow through by the air that air cleaner is cleaned like this in engine operation.The vaporized fuel of air chamber 12 is supplied to from supplying gaseous fuel device 14 through vaporized fuel ozzle 101 and 102 under the effect of negative pressure, reliably sucked corresponding Venturi tube part, simultaneously and above-mentioned air be mixed to form gaseous mixture, mixture enters cylinder.Because two input channels 21 and 22 are independent of one another, and correspond to two cylinders, even if because the time of the import negative pressure of time different initiations in input channel 21 with 22 of air inlet between two cylinders is different, the mutual interference of two cylinders 21 and 22 air inlet also can not be there is in input channel 21 and 22.Therefore the equilibrium of the air inflow of cylinder 21 and 22 can be obtained.A slider 24 can be set between two vaporized fuel ozzles 101 and 102, to be separated by air chamber 12.On slider 24, distance vaporized fuel ozzle 101 and 102 place farthest, arranges an opening 25, and two vaporized fuel ozzles 101 and 102 and the fuel inlet pipe 13 that arranges in the face of opening 25 couple together by it.The interference to the incoming pressure pulsation on other vaporized fuel ozzle 102 or 101 effectively can be prevented by slider 24.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
