Abstract
The utility model discloses a double-fuel supplying and converting means for automobile engines. Present reforming power performance of double fuel automobiles is usually 8-15% lower than the power performance of original design to certain extent. The utility model solves the problem and is provided with a gasoline electromagnetic stop valve (12) on the basis of oil supply systems of original automobile engines, the utility model is also provided with a gas supply switching device of liquefied petroleum gas. The liquefied petroleum gas is heated through a heating device and goes into a gas carburetor (11) through a one-way valve (9) and a pressure reducing valve (10), the liquefied petroleum gas is combined with air in an original carburetor (28), going into an engine cylinder to generate power by combustion. The utility model keeps the technical performance of dynamic design of original automobiles.
Description
The utility model relates to the automobile double fuel supply conversion equipment that a kind of steam supply car engine uses.
At present, Chang Yong automotive fuel generally can be divided into gasoline and diesel oil.In recent years many kinds occurred and used the dual-fuel automobiles, but the dual-fuel automobile power performance of most transformations of the way all there is in various degree decline than former design, generally between 8-15%.It is unreasonable that this mainly is that the dual-fuel automobile of the existing transformation of the way is supplied with conversion equipment.General combustion gas vaporizer all is installed on the air intlet of former car upper body, the aperture of the air intlet of former Carburetor is dwindled, increased the resistance that advances air, influenced the inlet of air, fuel can not fully be gasified in Carburetor, cause incomplete combustion, reduced the power of automobile; The air inlet metering-orifice of the existing general in addition combustion gas vaporizer that uses is certain, can not increase with the unlatching of former Carburetor stop valve, and what of air inflow can only lean on the degree of vacuum cylinder in to regulate, so cause the fuel supply deficiency, automobile power decline.
The purpose of this utility model is the deficiency that exists at above-mentioned prior art, and a kind of automobile double fuel supply conversion equipment is provided.
For reaching above-mentioned purpose, gasoline electromagnet cut off valve (12) has been installed on former car engine oil supply system, and design and installation the air feed conversion equipment of liquefied petroleum gas (LPG).The mutual conversion of supplying oil and gas system leans on the conversion of gasoline electromagnet cut off valve (12) and liquefied petroleum gas (LPG) electromagnet cut off valve (7) to realize: when needs use liquefied petroleum gas (LPG) to be used as power, close gasoline electromagnet cut off valve (12) and open liquefied petroleum gas (LPG) electromagnet cut off valve (7), liquefied petroleum gas (LPG) makes liquid warming be converted into gas by heating equipment (8), enter combustion gas vaporizer (11) through one-way valve (9) and reduction valve (10), in former Carburetor (28) with behind the air chemical combination, enter cylinder combustion burning generation power.
Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail:
Fig. 1 is the mounting structure schematic representation of automobile double fuel supply conversion equipment;
Fig. 2 is the structural representation of combustion gas vaporizer.
Number in the figure: (1) liquefied petroleum gas tank, (2) liquid level shows, (3) safety valve, (4) gas charging valve, (5) petrol gauge, (6) liquefied petroleum gas (LPG) pressure gauge, (7) liquefied petroleum gas (LPG) electromagnet cut off valve, (8) heating equipment, (9) one-way valve, (10) reduction valve, (11) combustion gas vaporizer, (12) gasoline electromagnet cut off valve, (13) heating pipe, (14) petrol tank, (15) petrol pump, (16) operation push rod, (17) plunger, (18) sealing cup, (19) liquefaction vaporizer main body, (20) suction port, (21) piston, (22) return spring, (23) gland, (24) combustion gas main jet hole, (25) idle metering jet, (26) fixed hole, (27) stop valve, (28) former Carburetor.
By Fig. 1 and Fig. 2 as can be known: the utility model has been installed gasoline electromagnet cut off valve (12) on former car engine oil supply system, and design and installation the air feed conversion equipment of liquefied petroleum gas (LPG).The liquefied petroleum gas transfer device is as follows from the order that liquefied petroleum gas tank (1) begins to connect respectively installation: liquefied petroleum gas tank (1) → liquid level display (2) → safety valve (3) → gas charging valve (4) → liquefied petroleum gas (LPG) pressure gauge (6) → liquefied petroleum gas (LPG) electromagnet cut off valve (7) → heating equipment (8) → one-way valve (9) → reduction valve (10) → combustion gas vaporizer (11).Combustion gas vaporizer (11) is installed in the other end of former car Carburetor (28), in the combustion gas vaporizer (11) is the plunger cavity, on establish pressure regulation sealing gland (23), for piston (21) is better resetted, return spring (22) is equipped with in the chamber thereon, piston (21) and plunger (17) link, and with the tight contact matching of operation push rod (16), sealing cup (18) is equipped with on the top of plunger (17).Operation push rod (16) is fixed on an end of former Carburetor stop valve (27) primitive axis.Under the effect of operation push rod (16) and piston (21), the gas of suction port (20) enters combustion gas main jet hole (24), enters cylinder internal combustion generation power in former Carburetor (28) with behind the air chemical combination.Section air valve UNICOM of liquefied petroleum gas (LPG) idle metering jet (25) and former Carburetor (28) lower end.Heating equipment is made up of the gas coil pipe that is sealed in the heating chamber in (8), and the import and export and the radiator of heating equipment (8) inner chamber circulating water join.
