Description
Technical field
Carburetor enrichment device used for general double-stroke engine on ice auger of the present invention relates to the carburetor enrichment device field on the two-cycle utility motor that is installed on the ice auger.
Background technique
Ice auger is for the device in ice face boring fishing, under the weather conditions of severe cold, the general purpose engine that is installed on the ice auger can easily be started, then should install the gasoline enrichment-system additional at Carburetor, can enter in the carburetor throat by the enriching oil supply gallery by the gasoline that the Carburetor enriching is indoor during engine start, in order to increase the indoor mixture strength of engine combustion, thereby motor started easily.
Summary of the invention
The purpose of this invention is to provide a kind of carburetor enrichment device used for general double-stroke engine on ice auger, by rotation enriching handle, promote upgrading valve in the Carburetor, make that to enter into enriching from gasoline in the oil input channel of enriching chamber indoor, enter carburetor throat by the enriching oil supply gallery again, increase the purpose that behind the indoor mixture strength of engine combustion motor is started easily to reach.
Carburetor enrichment device used for general double-stroke engine on ice auger, it comprises Carburetor, the enriching Handleset, paper gasket, air filter, construction bolt and petrol tank, Carburetor mounting hole at Carburetor, enriching Handleset mounting hole on the enriching handle bracket of enriching Handleset, be coated with construction bolt in the paper gasket mounting hole of paper gasket and the air filter mounting hole of air filter, form carburetor enrichment device, described carburetor enrichment device is installed on the two-cycle utility motor on the ice auger by described construction bolt, carburetor throat, enriching handle bracket vent, paper gasket vent and air filter base vent hole jointly install with one heart and link together; Paper gasket is installed between the enriching handle bracket and air filter of enriching Handleset; The enriching handle bottom of enriching Handleset contacts with the upgrading valve outer end of Carburetor; The oil vacuole top of Carburetor is connected with the petrol tank upper space by return check valve and return tube, the oil vacuole bottom of Carburetor is connected with gasoline separator in the petrol tank by in line check valve and oil inlet pipe, and gasoline separator is immersed in the gasoline of petrol tank; Oil vacuole in the Carburetor is leaded up to enriching chamber oil input channel, enriching chamber and enriching oil supply gallery and is connected with carburetor throat, and another road of oil vacuole is connected with carburetor throat by carburetor main reservoir compartment, the oily passage of main supply and carburetor needle valve.
Carburetor enrichment device used for general double-stroke engine on ice auger working principle of the present invention is described as follows:
When pressing the oil vacuole of Carburetor, after the gasoline separator of gasoline in the fuel tank in fuel tank filters, enter oil vacuole along oil inlet pipe through in line check valve, air and unnecessary gasoline will be got back in the fuel tank through return check valve and return tube, after repeatedly pressing the oil vacuole several, then can make gasoline one tunnel enter the enriching chamber of Carburetor through enriching chamber oil input channel, another road then enters the carburetor main reservoir compartment.
When the weather severe cold, motor is difficult to starting, at this moment clockwise rotate the enriching handle, then promotion upgrading valve in enriching handle bottom moves to left, and the upgrading valve seal ring on the upgrading valve is also moved to left, and the while compression retracteding position spring, at this moment, gasoline in the enriching chamber enters the enriching oil supply gallery through the original installation stop portion of upgrading valve seal ring and enters carburetor throat, thereby has increased mixture strength in the firing chamber of two-cycle utility motor, and motor is started.After the engine start, the enriching handle is rotated counterclockwise, return spring moves to right upgrading valve and upgrading valve seal ring to reset, and then the enriching oil supply gallery is closed.
After engine start successfully works, because the carburetor throat place produces negative pressure, gasoline enters carburetor throat from petrol tank through oil inlet pipe, in line check valve, oil vacuole, carburetor main reservoir compartment, main supply oil passage, enter at last the firing chamber of two-cycle utility motor, thereby guarantee to start function normally to move.
Because the throttle line on the motor drives the closure rotation, make the position that is inserted in the carburetor needle valve in the main supply oil passage that axial displacement occur, the passage section in the main supply oil passage is changed, the fuel delivery in flowing into carburetor throat also changes thereupon.
The structure of Carburetor is described as follows:
The indoor upgrading valve left end of enriching that is installed in Carburetor contacts with enriching handle bottom, and the right-hand member return spring indoor with being installed in enriching contacts, and is set with the upgrading valve seal ring at upgrading valve right-hand member seam.
Enriching Handleset structure is described as follows:
The enriching Handleset is comprised of enriching handle, enriching handle bracket, enriching handle bracket nut, lining and enriching handle bracket bolt, in the enriching handle, have enriching handle bracket bolt mounting holes, bending plate has the handle bracket bolt mounting holes on enriching handle bracket top, handle limiting stopper in that bending plate upper end in top has bending to link to each other carries out spacing to the rotation of enriching handle; The top bending plate of enriching handle bracket and bottom bending plate are connected as a body after by bending, enriching handle bottom can be rotated freely, and do not interfered; Have two enriching Handleset mounting holes at the bottom of enriching handle bracket bending plate, have enriching handle bracket vent at the middle part of the bottom of enriching handle bracket bending plate, for ambient air through air filter base vent hole, paper gasket vent, enriching handle bracket vent enter in the carburetor throat, forms combustion mixture with gasoline.
The support nut of enriching handle, lining and enriching handle bracket bolt are linked to be enriching Handleset single piece with enriching handle and enriching handle bracket.
Being installed in the carburetor enrichment device used for general double-stroke engine on ice auger advantage is two-cycle utility motor easily starting under the weather conditions of severe cold that can make on the ice auger, thereby has guaranteed the normal operation of motor, has improved the brill ice efficient of ice auger.
