Description

The reinforcement oil current breaker of carburetor type gasoline gaseous propellant engine

The utility model belongs to Carburetor under the situation that condition changes, and has to be used to control as increasing or the device of the fuel-air ratio of the charging that remains unchanged, and is specifically related to have the device of the cross-section area that is used to control fuel flow measurement hole.

The patent No. is 98232723.4, denomination of invention is the Chinese patent of " gaseous fuel and gasoline dual fuel engine Carburetor ", motor using gases fuel is when high load working condition turns round, enriching oil supply system with Carburetor provides gasoline to motor, because this Carburetor enriching metering-orifice is oversize, provide too much gasoline to motor, make mixture enrichment, the output power of motor can not increase, cause the economic performance of motor to descend, discharging increases.If reduce the size of Carburetor enriching metering-orifice, motor uses gasoline when high load working condition turns round, and the enriching system reduces to the amount of gasoline that motor provides, and has influence on the output power of motor when high load working condition.If reduce the amount of gaseous fuel, because automobile is in running, the working conditions change of motor is frequent, dynamic performance will satisfy and changes under the operating mode motor to request of Mixed Gases Density, then needing to be provided with sensor and automatic executing agency finishes and changes the gaseous fuel quantity that variation is provided to motor under the operating mode, this control mechanism complex structure, the cost of production height makes promoting the use of of this motor be restricted.

When being to provide a kind of using gases fuel for carburetor type gasoline gaseous propellant engine, the purpose of this utility model can cut off gasoline passage, the reinforcement oil current breaker of the carburetor type gasoline gaseous propellant engine of may command Fuel Petroleum flow measurement hole cross-section area when high load working condition turns round.

For achieving the above object, the solution that the utility model adopts is: be provided with coil in housing, end at housing is provided with end cap, establish the valve seat that the float chamber that is installed in carbureter main jet position and Carburetor and main oil gallery link at the other end of housing, the spool that the main jet that is interspersed with valve seat and outer cover are equipped with spring and are installed in spool conduit in the coil is set in valve seat.

Spool of the present utility model is: be arranged on the power metering-orifice that is installed in the carburetor main oil duct at a valve that connects with the valve rod end or combine as a whole, be arranged on the main jet of valve seat at another valve that joins with the valve rod middle part or be connected as a single entity.

The utility model has solved carburetor type gasoline gaseous propellant engine can cut off gasoline passage at using gases fuel, when the motor high load working condition turns round, provide the optimum mixture ratio Fuel Petroleum to motor, saved gasoline, reduce environmental pollution, improved the power character and the economic performance of motor.After using this device, more than 96% of power when motor can reach use gasoline with gas-powered power, using gases fuel and gasoline can be changed fast.It has advantages such as simple in structure, easy to use, that economic performance is good, can promote the use of on carburetor type gasoline gaseous propellant engine.

Fig. 1 is an embodiment's of the utility model structural representation and the utility model and the schematic representation that connects of Carburetor.

Below in conjunction with drawings and Examples the utility model is further described, but the utility model is not limited to the following examples.

In Fig. 1, the utility model is installed in the main jet position of gasoline gas fluid fuel engine and carburetor, during installation, the former main jet of Carburetor is taken down.

Present embodiment is to be made of housing 1, coil 2, end cap 3, spool conduit 4, spool 5, spring 6, sealing gasket 7, valve seat 8, connection.Coil 2 is installed in housing 1, the central position of coil 2 is equipped with spool conduit 4, the right-hand member of housing 1 is connected with end cap 3, the left end of housing 1 is connected with valve seat 8, between valve seat 8 and the housing 1 sealing gasket 7 is housed, the central position of valve seat 8 left ends be processed with main jet 1 ', spool 5 is installed in valve seat 8, the right side of spool 5 is surveyed cover and is packed in the spool conduit 4, can be spool conduit 4 in move left and right, spool 5 is set with springs 6 outward.When the circuit power of closing coil 2, under the electromagnetic force effect of coil 2, spool 5 moves right, and when turn-offing the circuit power of coil 2, under the elastic force effect of spring 6, spool 5 is moved to the left.

The spool 5 of present embodiment is made of valve rod 5-1, valve 5-2, valve 5-3.A valve 5-3 is conical, and 5-1 is connected as a single entity with valve rod, is arranged on valve rod 5-1 left end.Another valve 5-2 is a frustoconic shape, and 5-1 is connected as a single entity with valve rod, is arranged on valve rod 5-1 middle part.Valve rod 5-1 is installed in the valve seat 8, valve 5-2 be placed on the main jet 1 of valve seat 8 left end central positions ' in, valve rod 5-1 and main jet 1 ' between form the annular pass, the cross-section area that the cross-section area Ying Yuyuan of annular pass is installed in main jet on the Carburetor 10 equates.When the utility model is installed, take down the main jet on the Carburetor 10, sealing gasket 9 is installed on valve seat 8, the utility model is installed in the main jet position of Carburetor 10, valve 5-3 just in time be placed on be installed on main oil gallery 2 ' power metering-orifice 12 on, and maintaining certain distance, the size of power metering-orifice 12 amount of gasoline of flowing through adopts the thickness of adjusting adjustment packing ring 13 between power metering-orifice 12 and the Carburetor 10 to determine.The utility model adopts the spool 5 of this structure, when motor using gases fuels run, the circulation cross-sectional area of power metering-orifice 12 is reduced, and when motor turned round at high load working condition, the amount of gasoline of the power metering-orifice 12 of flowing through reduced.

Working procedure of the present utility model is as follows:

As operator if when making the gasoline gaseous propellant engine use the Fuel Petroleum running, connect circuit power of the present utility model, coil 2 energisings, spool 5 moves right, main jet 1 ' open, gasoline from the float chamber 4 ' main jet 1 of flowing through of Carburetor 10 ', the power metering-orifice 12 of Carburetor 10, enter the main oil gallery 2 of Carburetor 10 ', motor turns round with Fuel Petroleum.As operator if when making gasoline gaseous propellant engine using gases fuels run, turn-off circuit power of the present utility model, under the effect of spring 6 elastic force, spool 5 is moved to the left, another valve 5-2 of spool 5 is with the main jet 1 of valve seat 8 left ends ' close, a valve 5-3 of spool 5 turns down power metering-orifice 12, when motor turns round at high load working condition, the upgrading valve 11 that operator can operate the enriching system of Carburetor 10 moves down, gasoline through the enriching metering-orifice 3 of Carburetor 10 enriching systems ', the power metering-orifice 12 of Carburetor 10 enter the main oil gallery 2 of Carburetor 10 ', when high load working condition turns round, provide best mixed gas ratio to motor, the output power of motor is increased.
