Abstract

The utility model discloses a dual functional fuel instant switcher, which comprises a carburetor(5). The utility model is characterized in that: a float chamber(2) is connected between the electromagnetic valve(10) and the carburetor(5); a main effuser(4) is arranged in the float chamber(2); a carburetor thimble is arranged in the main effuser(40; the top of an electromagnetic needle(3) pushes up to the bottom of the main effuser(4). The utility model can switch the petrol and natural gas and has the advantage of saving energy.

Description

The instantaneous switch of dual-purpose fuel

(1). technical field

This practicality relates to Carburetor, the instantaneous switch of particularly a kind of dual-purpose fuel.

(2). background technique

At present, the part motorcycle adopts gasoline and rock gas to act as a fuel.Usually the mutual conversion of gasoline and rock gas is to realize by the break-make that installs a gasoline electromagnetic valve oil circuit on gasoline line additional in the double fuel motorcycle.In transfer process,, after gasoline solenoid valve gasoline in pipeline gasoline between the Carburetor and the carburetor bowl must being used up, motor could be switched to the rock gas state from the gasoline state for avoiding oil, gas multifuel combustion.Otherwise need could switch to the gasoline state from the rock gas state after waiting for that carburetor bowl has gasoline.This method often causes the waste of gasoline, also loses time simultaneously.

(3). the model utility content

The purpose of this utility model provides the instantaneous switch of a kind of dual-purpose fuel.It can also have the characteristics of energy saving at instantaneous switching gasoline and rock gas.

For reaching above-mentioned purpose, the utility model is connected float chamber between solenoid valve and Carburetor, be provided with the main jet pipe in the float chamber, lays the Carburetor thimble in the main jet pipe, and the top of electromagnetism needle withstands on main jet pipe bottom.

The utility model is owing to directly control the solenoid valve needle through and off of carbureter main jet oil-feed place, after the minimizing motor must finish remaining gasoline combustion the float chamber when the gasoline state switches to the rock gas state, be converted to the process of rock gas again, therefore can energy saving and time.

Below in conjunction with accompanying drawing the utility model is described further.

Fig. 1 is this switch assembly sketch;

Fig. 2 is the local figure of carburetor bowl;

Fig. 3 is a work block diagram of the present utility model.

(5). embodiment

Referring to Fig. 1 and Fig. 2.Be connected float chamber 2 between solenoid valve 1 and Carburetor 5, be provided with main jet pipe 4 in the float chamber 2, lay the Carburetor thimble in the main jet pipe 4, the top of electromagnetism needle 3 withstands on main jet pipe 4 bottoms, and electromagnetism needle 3 tops are corresponding with main jet pipe 4 bottom shapes.The Carburetor thimble is placed in the upper end in the main jet pipe 4.

This switch one termination suction tude, the positive and negative polar curve that another termination mixer, solenoid valve are drawn need connect the positive and negative electrode of control circuit on the double fuel motorcycle.

Referring to Fig. 3.In use, when the throw over switch of control circuit on the motorcycle is pushed the gasoline position, this moment, low-voltage solenoid valve was closed, solenoid valve on the instantaneous switch of dual-purpose fuel is opened, solenoid valve needle 3 moves down under the effect of magnetic force, gasoline in the float chamber 2 enters main jet pipe 4, and Carburetor normal fuel injection, motor are in the gasoline state that burns; When the throw over switch of control circuit pushes the rock gas position on motorcycle, solenoid valve 1 on the instantaneous switch of dual-purpose fuel cuts out, solenoid valve needle 3 moves up under the effect of contained spring power, and the gasoline of closing in the float chamber enters in the main jet pipe 4, and low-voltage solenoid valve is opened.At this moment, pass through low-voltage solenoid valve, pass through dynamic valve again, enter mixer, after air mixing,, finally enter engine chamber by electromagnetism Carburetor, suction tude from the natural gas via decompressor decompression back that gas cylinder comes out.Motor is in and burns the rock gas state, has realized the instantaneous switching of two kinds of fuel.

Claims

1. instantaneous switch of dual-purpose fuel, comprise Carburetor (5), it is characterized in that: between solenoid valve (1) and Carburetor (5), be connected float chamber (2), be provided with main jet pipe (4) in the float chamber (2), the main jet pipe is laid the Carburetor thimble in (4), and the top of electromagnetism needle (3) withstands on main jet pipe (4) bottom.

2. the instantaneous switch of dual-purpose fuel according to claim 1 is characterized in that: electromagnetism needle (3) top is corresponding with main jet pipe (4) bottom shape.

3. the instantaneous switch of dual-purpose fuel according to claim 1 is characterized in that: the Carburetor thimble is placed in the upper end in the main jet pipe (4).
