Abstract
The utility model discloses a gaseous feeding device of internal -combustion engine, include booster (1), steady voltage case (2) and take the carburetor of float chamber to organize, steady voltage case (2) are including air inlet and gas outlet, booster (1) and air inlet intercommunication, carburetor group and gas outlet intercommunication the outer wall of steady voltage case (2) is provided with electromagnetism three -way valve (3), electromagnetism three -way valve (3) and steady voltage case (2) intercommunication, and steady voltage case (2) are through electromagnetism three -way valve (3) the float chamber intercommunication with carburetor group. The utility model has the advantages of simple structure, low cost, adopt it to adjust the gas of supplying with to the carburetor according to the ambient pressure of difference, adjust the oil -fired concentration of carburetor for the burning of combustion chamber is more abundant, and exhaust emissions up to standard simultaneously, has still reduced the loss of power, has reduced the oil consumption.
Description
Technical field
The utility model relates to a kind of internal-combustion engine, particularly a kind of internal combustion engine gas supplier.
Background technique
The utility model patent that a kind of name is called " Preturbine pressure increasing gasoline engine " is disclosed in CN2109450U, this petrol engine is before Carburetor, install a turbosupercharger and pressure stabilizer additional, and adopt multiple pulse reversable outlet pipe, square-section suction tude and set up a lubricating oil path, by main oil gallery through oil filter to pressurized machine, and flow back into oil sump by below pressurized machine.Although the petrol engine of this structure, the problem in high altitude localities petrol engine power drop can be solved, but, under petrol engine is in high altitude environment, when the situation of its external pressure instability occurs, make the unstable gas to Carburetor supply, there is too high or too low situation in the pressure of carburetor bowl, cause burning insufficient, exhaust emissions is not up to standard, engine power loss is large, and oil consumption increases.
Model utility content
The purpose of this utility model is just to provide a kind of internal combustion engine gas supplier that can carry out fuel concentration adjustment to Carburetor.
The purpose of this utility model is realized by such technological scheme, a kind of internal combustion engine gas supplier, comprise the Carburetor group of pressurized machine, pressure stabilizer and band float chamber, described pressure stabilizer comprises suction port and air outlet, described pressurized machine is communicated with suction port, described Carburetor group is communicated with air outlet, it is characterized in that: the outer wall of described pressure stabilizer is provided with three-way solenoid valve, described three-way solenoid valve is communicated with pressure stabilizer, and pressure stabilizer is communicated with by the float chamber of three-way solenoid valve with Carburetor group.
Further describe, described Carburetor group comprises Carburetor A and Carburetor B, and described air outlet is two, and described Carburetor A and Carburetor B are communicated with two air outlets respectively, and described three-way solenoid valve is communicated with Carburetor B with Carburetor A respectively by three-way pipe.
Wherein, described three-way solenoid valve comprises outlet nozzle and two air inlet nozzles, and described pressure stabilizer comprises main airway and distal airways, and described two air inlet nozzles are communicated with distal airways with main airway respectively by pipeline, and described outlet nozzle is communicated with three-way pipe by pipeline.
Owing to have employed technique scheme, the utility model has structure advantage simple, with low cost, adopt it can regulate carburettor float chamber pressure according to different external pressures, and then the concentration of the fuel oil of Carburetor is regulated, make the burning of firing chamber more abundant, exhaust emissions reaches standard, simultaneously, also reduce the loss of power, reduce oil consumption.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail; but the utility model is not limited to these mode of executions; any improvement or alternative on the present embodiment essence spirit, still belongs to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a kind of internal combustion engine gas supplier, comprise the Carburetor group of pressurized machine 1, pressure stabilizer 2 and band float chamber, described pressure stabilizer 2 comprises suction port and air outlet, described pressurized machine 1 is communicated with suction port, and described Carburetor group is communicated with air outlet, and the outer wall of described pressure stabilizer 2 is provided with three-way solenoid valve 3, described three-way solenoid valve 3 is communicated with pressure stabilizer 2, and pressure stabilizer 2 is communicated with the float chamber of Carburetor group by three-way solenoid valve 3.
Wherein, described Carburetor group comprises Carburetor A4 and Carburetor B5, and described air outlet is two, and described Carburetor A4 and Carburetor B5 are communicated with two air outlets respectively, and described three-way solenoid valve 3 is communicated with Carburetor B5 with Carburetor A4 respectively by three-way pipe 6.
Further, described three-way solenoid valve 3 comprises outlet nozzle and two air inlet nozzles, described pressure stabilizer 2 comprises main airway 7 and distal airways 8, and described two air inlet nozzles are communicated with distal airways 8 with main airway 7 respectively by pipeline, and described outlet nozzle is communicated with three-way pipe 6 by pipeline.
In the utility model, when internal-combustion engine is in normal state, the gas in pressure stabilizer 2 enters into three-way solenoid valve 3 by distal airways 8, enters into three-way pipe 6 by three-way solenoid valve 3, and then enter into Carburetor A4 and Carburetor B5 respectively, ensure the normal air feed of Carburetor.
When hypotony in Carburetor A4 and Carburetor B5, now three-way solenoid valve 3 carries out work, gas in pressure stabilizer 2 just enters into three-way solenoid valve 3 from main airway 7, then Carburetor A4 and Carburetor B5 is entered into by three-way solenoid valve 3 and three-way pipe 6, because in pressure stabilizer 2, the pressure of main airway 7 is larger, so just can balance pressure too low in Carburetor, have adjusted the concentration of Carburetor intermediate fuel oil, ensure that the burning of firing chamber is more abundant.
