Abstract
The utility model discloses a double-supply system for the engines which is a double-supply system used for the mixing use of the gasoline and one of the fuels of the methanol, the ethanol, the benzene and the residual liquid of the liquefied petroleum gas of the vehicle engine. The utility model is characterized in that the structure of a dual-fuel carburetor in the double-supply system is carried out the creative improvement; the measuring orifice assembly of the prior art is integrally combined with a jet pipe, and the measuring orifice assembly is raised to the interior from the lower part of a float chamber, and is on the same line with a nozzle; the measuring orifice assembly is arranged on the position which is about 4 mm from the end of the jet pipe. Consequently, the variation range is in (+/-) 3% when the gasoline and one of the fuels are mixed to be burnt, and the purposes of stabilizing the operation of the engine and relieving the lack of the power fuel are obtained.
Description
The dual fuel supply system of the utility model motor relates to the dual fuel supply system of gasoline automobile with motor, the two supply systems of the double fuel that a certain fuel and gasoline fusion are used.
According in March, 87 " oilman skill " magazine the 5th volume, it is similar substantially that bright " the three kinds of discussions of mixing firing method of methyl alcohol and gasoline " delivered of the Wang Ke of this seminar of the second phase first page of report two improve the collect technological scheme of the 3rd ethanol that collects the 45th page disclosed " Yunnan Province's ethanol is for the test and the application of firing ", gasoline packing multifuel combustion of compensation scheme and the substitute fuels of being published by " oilman skill " editorial office in July, 87 for system's second generation.Its common trait all is that Carburetor is made up of double float chamber, double venturi, and its metering-orifice assembly (comprising metering-orifice and metering-orifice seat) is located at the float chamber below, below the liquid level in the float chamber.The phenomenon of seepage methyl alcohol because of the junction point of metering-orifice assembly and float chamber, can take place in the dual fuel supply system of this kind structure frequently; And the passage of quantity of methyl alcohol pitch-row methyl alcohol spout process is longer, it is slower to be that the degree of vacuum change information of spout impression passes to methyl alcohol metering-orifice place, cause methyl alcohol and gasoline to mix the mixing ratio amplitude of variation bigger, wave range is up to ± 6%, this fluctuation directly causes the engine operation instability.
The purpose of two supply systems of the utility model motor is to overcoming the defective that above-mentioned motor dual fuel supply system exists, thereby provide a kind of certain fuel that utilizes, the raffinate and the gasoline that are methyl alcohol, ethanol, benzene or liquefied petroleum gas (LPG) are mixed the technological scheme that burning can make the dual fuel supply system of motor stable operation, reach to alleviate dynamic combustion purpose in short supply.
Two supply systems of the utility model motor, promptly by methyl alcohol, ethanol, benzene or LPG (liquefied petroleum gas) residual liquid are two supply systems that second kind of fuel and gasoline are mixed burning, its pair supply system is by double fuel Carburetor 1, empty filter 2, second petrolift 3, second fuel filter 4, second fuel tank 5, petrol tank 6, gasoline filter 7, petrol pump 8, fuel conduit 9, suction tude 10, solenoid valve 11, mixing chamber 12 is formed, (as shown in Figure 1), wherein double fuel Carburetor 1 is again by float 14, float chamber 15, small venturi 16, middle trunnion 17, big trunnion 18, jet pipe 19, metering-orifice 20, compensate opening 21, throttle valve 22 is formed (as shown in Figure 2), it is characterized in that metering-orifice assembly and jet pipe in this seminar second generation compensation scheme are integrated, and is about to metering-orifice 20 positions and is increased in the jet pipe 19, jet pipe is arranged in the top of big trunnion 18 and trunnion 17, the jet pipe opening is positioned at the inboard of small venturi 16, and near 4 millimeters of jet pipe 19 afterbodys, the position of its metering-orifice 20 and spout 23 in a straight line, metering-orifice 20 diameters can be according to gasoline and the kind of mixing second kind of fuel of burning, proportioning and engine power size factor are determined, its excursion between 0.5～1.0mm, i.e. metering-orifice length/metering-orifice diameter=1.5～2.0, jet pipe 19 is arranged in the top of big trunnion 18 and trunnion 17, jet pipe is opened on the inboard of small venturi 16, three compensate openings 21 are evenly distributed on the jet pipe 19, and the diameter of its compensate opening 21 is between 0.4～0.9mm, and whole jet pipe is made with brass.All connect between each parts on the accompanying drawing 1 with the copper pipe of internal diameter φ 8, the two supply systems of motor of an a large amount hole structure have so just been created, this system can guarantee under each operating mode of motor in the scope of fluctuation ± 3% of two kinds of fuel mixed-fuel burning proportions, and guarantee that engine operation is stable.
Two supply systems of the utility model motor, to burn methyl alcohol is example to mix, and two supply systems of its enforcement are by double fuel Carburetor 1, empty filter 2, methanol pump 3, methyl alcohol filter 4, methanol tank 5, petrol tank 6, gasoline filter 7, petrol pump 8, fuel conduit 9, suction tude 10, solenoid valve 11, mixing chamber 12 is formed (as shown in Figure 1), and wherein double fuel Carburetor 1 is again by float 14, float chamber 15, small venturi 16, middle trunnion 17, big trunnion 18, jet pipe 19, metering-orifice 20, compensate opening 21, throttle valve 22 compositions (as shown in Figure 2) is characterized in that metering-orifice 20 and jet pipe 19 are integrated, and it is interior near 4 millimeters of jet pipe 19 afterbodys that soon metering-orifice 20 positions are increased to jet pipe 19.Jet pipe is arranged in the top of big trunnion 18 and trunnion 17, the inboard of small venturi 16.The position of its metering-orifice 20 and spout 23 in a straight line, the diameter of its metering-orifice is 0.6mm, compensate opening 21 is evenly distributed on the jet pipe 19, its diameter is that the jet pipe of 0.5 millimeter integral body is made with brass.Native system has been avoided methyl alcohol and has been mixed with the liquid of gasoline, and methyl alcohol mixes in the mixing chamber (12) of Carburetor after the atomizing respectively in the trunnion of Carburetor with gasoline, enters motor 13 through suction tude 10.
Two supply systems of the utility model motor, because metering-orifice 20 is integrated with jet pipe and so metering-orifice 20 is greatly improved apart from spout 19 nearer flowing states to metering-orifice 20 places, the degree of vacuum of spout 19 changes the variation in pressure that is reflected to metering-orifice 20 the place aheads (along the fuel flow direction) very soon, the vacuum pressure of adding compensate opening 21 places also has influence on the pressure in metering-orifice the place ahead with engine load, the information of above-mentioned two degree of vacuum is synthetic, is controlling the vacuum pressure in metering-orifice the place ahead simultaneously.The changes in flow rate of metering-orifice 20 changes with engine load like this good cooperating automatically, cause the mixing ratio of mixing of main fuel gasoline and second kind of fuel that good stable is arranged, fluctuation is within ± 3%, thereby make motor mix working stability when burning two kinds of fuel, to alleviate power fuel in short supply play a part very important.
