Abstract
The utility model provides a double-fuel automobile gas device on which a gas device is additionally arranged in the situation that the structure and the collocation of the original gasoline automobile and the original diesel automobile are not changed. The double-fuel automobile gas device makes the gas fuel of liquefied gas orderly guided to obtain the working requirements of an engine, and the fuel drives the automobile to run by doing work. The utility model is characterized in that a liquefied gas storage steel bottle 1 and a constant temperature constant voltage controller 3 are connected through a pipeline A. A speed regulating controller 6 and the constant temperature constant voltage controller 3 are connected by a pipeline B. A fuel gas gasifier 10 and the speed regulating controller 6 are connected by a pipeline C. The lower part of an automobile carburetor 12 is provided with the gas gasifier 10.
Description
The utility model belongs to the layout field that vehicular propulsion combines with fuel feeding, specifically a kind of dual-fuel automobile gas combustion apparatus.
At present, known automotive engine is a piston type internal combustion engine, mainly is divided into two big class, i.e. gasoline car and diesel-powered vehicles by the situation of using fuel.
Gasoline car is by petrol feed pump the suction of the fuel oil in the fuel tank to be delivered on the carburettor at engine inlet port place, by carburettor with liquid fuel in the quick breathing process of driving engine and the negative pressure that causes, under the effect of carburettor,, under the effect of piston operation, suck cylinder, compression, igniting, work done with oil plant atomizing and air-blending.
Diesel-powered vehicle then is by diesel oil pump the suction of the fuel oil in the fuel tank to be delivered to the high pressure pump pressurization, supplies with each cylinder injector in an orderly manner through distributor, sends into each cylinder compression knock work done by fuel injector.
Above-mentioned vehicle is in the fuel use, back formation atomized particles is still thicker because fuel process carburettor or fuel injector are forced to atomize, entering the cylinder front and back, around runner and combustion chamber, cause wallboard to stay collection easily, increased the carbide metal that waste of fuel and incomplete combustion cause and gathered, the unobstructed ability of runner is weakened, wearing and tearing strengthen in the cylinder, engine temperature raises, and the pernicious gas of discharging and smoke intensity increase, and cause environmental pollution.
The purpose of this utility model then is the problem that exists at above-mentioned prior art, provide a kind of under the situation that does not change former gasoline automobile, diesel car structure, configuration, an additional cover gas combustion apparatus, make LNG gasifaction fuel import the need of work that reaches driving engine in order, the burning work done drives the dual-fuel automobile gas combustion apparatus of automotive operation.Be intended to reach inhibition emission pollutants, energy-saving and cost-reducing, prolongation engine life.
The purpose of this utility model can reach by following measure:
A kind of dual-fuel automobile gas combustion apparatus, it is characterized in that liquified gas storage steel cylinder 1 is with constant temperature, constant-voltage controller 3, link to each other by pipeline A, speed setting controller 6 links to each other with constant temperature, constant-voltage controller 3 through pipeline B, combustion vapour gasifier 10 links to each other with speed setting controller 6 through pipeline C, and automobile carburetor 12 bottoms are provided with combustion vapour gasifier 10.
The purpose of this utility model can also reach by following measure:
Airfilter 16 links to each other through pipeline I and electrical generator 14 synchronous air boost pumps 13, and boost pump 13 is connected to automobile carburetor 12 through pipeline H;
Lubricated modulator 15 pipeline D are connected to combustion vapour gasifier 10.
The utility model has following advantage compared to existing technology:
Owing to adopted such scheme, the dual-fuel automobile gas combustion apparatus not only can make autogas, liquefied fuel gass such as liquefied natural gas are used for piston of automobile formula driving engine and carry out functional conversion, make it to reach the power needs of automotive operation, simultaneously because gaseous fuel and air-blending are abundant, combustion flame temperature is lower than liquid fuel (gasoline usually again, diesel oil) more than 20%, thereby can reduce the wallboard that fuel mixture under the hot merit state enters before and after the cylinder widely and stay collection, reduced waste of fuel, the peroxide in the combustion process and the reaction chance for survival of objectionable impurities have been alleviated, alleviated carbon shape thing in the combustion chamber gather with het expansion to wearing and tearing that driving engine caused, distortion harm, prolong the service life of driving engine, reduced operation and maintenance cost.But the supply situation of while based on fuel, fueling to driving engine is switched anywhere or anytime, reached combustion fluid gasification when blue gas is arranged, gasoline car burns gasoline during no blue gas, diesel-powered vehicle burning diesel oil and do not influence the effect of former engine design power.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described:
The utility model is through pipeline A fuel to be flowed to constant temperature by liquified gas storage steel cylinder 1, constant-voltage controller 3, be positioned at constant temperature, constant temperature PTC2 in the constant-voltage controller 3 and driving engine operation heat recirculated water are supplied with constant temperature by pipeline E.F circulation, under the preceding topic of constant-voltage controller 3, make the fuel vaporization of fully reforming, smart filter, simultaneously by being positioned at constant temperature, the collaborative work of the constant-voltage controller 4 on constant-voltage controller 3 tops makes the fuel vapor constant voltage, to fire vapour through pipeline B output and deliver to speed setting controller 6 (this moment, control electromagnetic valve 5 was for opening shape), affect automobile carburetor and combustion gas connecting rod 8 by the gas control pedal, line 9 drives governor adjusting arm 7 and makes the height of fuel by automotive operation, in, low, the operation requirements of idling and chaufeur is adjusted arbitrarily, fuel is given combustion vapour gasifier 10 through pipeline C after adjusting, the auxiliary of carburettor 12 on automotive air intake pipe Connection Block 11 mixes with air is organic down, is inhaled into the cylinder compression in an orderly manner, igniting, the outburst work done, blow down gas is finished the function conversion of driving engine.
For the vaporized fuel that makes low carbon chain is brought into play its hot merit effect better, issuable spill and leakage harm when preventing vaporized fuel malleation input combustion vapour gasifier 10, special give the air boost pump 13 synchronous by airfilter 16 through pipeline I with electrical generator 14 with air, by air boost pump 13 superchargings after pipeline H gives automobile carburetor 12.
In order to solve the drawback of the unlubricated additive of liquefied gas as fuel, detergent-dispersant additive, prevent relative wear and the carbide metal gathering under high temperature, high pressure, high-speed motion situation of engine piston, piston ring, cylinder, so having set up lubricated modulator 15 again gives combustion vapour gasifier 10 through pipeline D and is mixed into cylinder with combustion vapour and lubricates, be intended to improve the service life of driving engine, frictional resistance when reducing each functional exercise parts operation is to guarantee the good performance of engine power.
When running out of gas in the liquified gas storage steel cylinder, open fuel solenoid valve 17 (firing steam valve simultaneously closes) by the hybrid fuel change-over swith, fuel is just by fuel tank 19, by pipeline G, under fuel charger 18 is assisted, fuel is delivered to carburettor 12, fire an engine work drives automobile and continues ahead running.
