Description
Technical field
The utility model relates to a kind of natural gas double-driving driving and uses the LNG supply system.
Background technique
Existing natural gas used for automobile system; Only be applicable to urban district short distance transportation, and when situation such as appearance climbing, power is obviously not enough; In today that oil price skyrockets day by day; The utilization ratio of rock gas is increasingly high, but how can this clean energy resource be used for long-distance vehicle, is a difficult problem always.
The model utility content
The technical problem that the utility model solves: provide a kind of natural gas double-driving to drive and use the LNG supply system, for dual-power engine provides gas fuel, car load is installed four 450 liters of LNG gas cylinders, and two bottles are one group and can give corresponding motor air feed respectively.
The technological scheme that the utility model adopts: natural gas double-driving drives uses the LNG supply system; Said supply system comprises four gas cylinders; Two of said gas cylinders are one group and place the vehicle frame both sides respectively; Said two groups of gas cylinders are separately installed with can give the vaporization module of gas cylinder supercharging, and said two groups of gas cylinders are given corresponding motor air feed respectively.
Wherein, Said four gas cylinders are No. 1 gas cylinder, No. 2 gas cylinders, No. 3 gas cylinders and No. 4 gas cylinders, are fixed on the vehicle frame left side after said No. 1 gas cylinder and No. 2 gas cylinder serial connections, are fixed on the vehicle frame right side after said No. 3 gas cylinders and No. 4 gas cylinder serial connections; Said No. 1 gas cylinder and No. 3 gas cylinder output terminals connect the knock out drum input end respectively; Said knock out drum output terminal connects the decompressor input end respectively, and said decompressor output terminal connects the electromagnetic shut-off valve input end respectively, and said electromagnetic shut-off valve output terminal connects combustion gas filter cleaner input end respectively; Said combustion gas filter cleaner output terminal connects the voltage stabilizer input end respectively, and said output end of voltage stabilizer connects left and right motor input end respectively.
Further, all be fixed with the gas cylinder catch fan outside said four gas cylinders.
The utility model compared with prior art is applicable to remote haulage vehicle, and clean environment firendly, and compact structure has higher utility.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that the A-A of Fig. 1 is to view.
Embodiment
A kind of embodiment of the utility model is described below in conjunction with accompanying drawing 1,2.
Natural gas double-driving drives uses the LNG supply system; Comprise four 450L, LNG LNG Liquefied natural gas gas cylinder, two of gas cylinders are one group and place vehicle frame 7 both sides respectively; Two groups of gas cylinders are separately installed with 6, the two groups of gas cylinders of vaporization module that can give the gas cylinder supercharging and give corresponding motor air feed respectively.
Four gas cylinders are 2, No. 3 gas cylinders 3 of 1, No. 2 gas cylinders of No. 1 gas cylinder and No. 4 gas cylinders 4; Be fixed on vehicle frame 7 left sides after four gas cylinder outsides all are fixed with 5, No. 1 gas cylinders 1 of gas cylinder catch fan and No. 2 gas cylinder 2 serial connections, be fixed on vehicle frame 7 right sides after No. 3 gas cylinders 3 and No. 4 gas cylinder 4 serial connections; No. 1 gas cylinder 1 and No. 3 gas cylinder 3 output terminals connect knock out drum 8 input ends respectively; Knock out drum 8 output terminals connect decompressor 9 input ends respectively, and decompressor 9 output terminals connect electromagnetic shut-off valve 10 input ends respectively, and electromagnetic shut-off valve 10 output terminals connect combustion gas filter cleaner 11 input ends respectively; Combustion gas filter cleaner 11 output terminals connect voltage stabilizer 12 input ends respectively, and voltage stabilizer 12 output terminals connect left and right motor input end respectively.
Working principle: have 4 450L in this system, LNG (LNG Liquefied natural gas) gas cylinder is divided into two bottles one group; Totally two groups, place vehicle frame 7 left and right sides, this group of right side is put motor to the right side and is supplied fuel; Two groups air feed principle is identical, does following explanation with regard to its working principle: at first, the LNG LNG Liquefied natural gas is added to the 450L gas cylinder with special device at present; Because at this moment rock gas has passed through pressurization and has lowered the temperature to handle and existed with liquid form, in order to improve the gas cylinder pressure inside, vaporization module 6 has been installed; Its principle is the hot water and the liquid capable heat exchange of rock gas that utilizes in the water tank; Natural gas gasifying is got into gas cylinder again, its pressure of the inside of a bottle is increased, thereby help to the motor air feed.When giving the motor air feed, rock gas comes out through knock out drum 8-decompressor 9-electromagnetic shut-off valve 10-combustion gas filter cleaner 11-voltage stabilizer 12-motor from gas cylinder earlier.Wherein, knock out drum 8 mainly is that to guarantee to get into the gas pressure of motor stable; The main effect of decompressor 9 is to reduce pressure; The effect of electromagnetic shut-off valve 10 is when system's gas leakage or overpressure, to cut off source of the gas, plays the safety protection effect; The 11 main effects of combustion gas filter cleaner are the impurity in the divided gas flow; The main effect of voltage stabilizer 12 is stable gas pressure when regulating engine charge pressure.
The foregoing description, just the preferred embodiment of the utility model is not to be used for limiting the utility model practical range, so all equivalences of being done with the said content of the utility model claim change, all should be included within the utility model claim scope.
