Description

Technical Field

[0001] This utility model relates to the field of carburetor manufacturing technology, specifically to an adjustable flow carburetor. Background Technology

[0002] A carburetor is a mechanical device that mixes gasoline and air in a certain proportion under the vacuum generated by the engine. The carburetor automatically mixes the appropriate concentration and outputs the appropriate amount of air-fuel mixture according to the different working conditions of the engine. In order to make the air-fuel mixture more uniform, the carburetor also has the effect of atomizing the fuel for normal operation of the machine.

[0003] Traditional carburetors cannot monitor fuel flow in real time, thus failing to control fuel supply to the fuel lines as needed. This inability to adjust flow accurately and in real-time according to operating conditions leads to reduced engine efficiency, increased fuel consumption, and even excessive emissions, impacting environmental performance. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable flow carburetor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable flow carburetor, comprising a carburetor body, an inlet pipe installed at the inlet end of the carburetor body, a flow meter and a control valve installed on the inlet pipe, an iron cover fixed to the other end of the carburetor body by screws, a float cover plate fixed to the top of the carburetor body by screws, a float assembly installed on the float cover plate, and a fuel filter and a throttle assembly installed on the rear top side of the carburetor body.

[0006] Preferably, an air conditioning sleeve is fixedly installed on the carburetor body, and an air conditioning screw is installed on the air conditioning sleeve.

[0007] Preferably, an idle speed adjusting sleeve is fixedly provided on the carburetor body, and an idle speed adjusting screw is installed on the idle speed adjusting sleeve.

[0008] Preferably, a tapered venturi tube with a cone angle of 12°-15° is provided above the throttling component.

[0009] Preferably, the float assembly includes a float adjusting column, a float needle valve installed at the bottom of the float adjusting column, and a float body installed at the bottom of the float needle valve.

[0010] Preferably, the throttle assembly includes a threaded knob, an oil needle mounted at the bottom of the threaded knob, a throttle valve sleeved on the oil needle, and a valve seat located below the throttle valve and connected to the throttle valve.

[0011] Preferably, the inlet end of the carburetor body is provided with an oil inlet groove, and the upper surface of the carburetor body is equipped with a throttle chamber and a float chamber.

[0012] The beneficial effects of this invention are as follows: When in use, a flow meter and a control valve are installed on the fuel inlet pipe. The flow meter monitors the fuel flow rate entering the carburetor in real time, ensuring accurate fuel supply. The control valve adjusts the fuel supply according to actual needs, enabling flexible adjustment of the carburetor flow rate. When fuel consumption causes the fuel level to drop, the float assembly descends, opening the fuel inlet to allow fuel to flow in. When the fuel level rises, the float assembly rises and closes the fuel inlet, ensuring the fuel quantity is maintained at a suitable level. This ensures the engine receives an accurate proportion of fuel under different operating conditions, thereby improving engine power output and fuel economy. This invention improves fuel efficiency, reduces fuel waste and exhaust emissions. Because a fuel filter is installed on the top rear side of the carburetor, it effectively filters out impurities and particulate matter from the fuel, ensuring that the fuel entering the carburetor is pure and free of impurities. This prevents excessive impurities in the fuel from clogging the carburetor's internal channels, affecting normal fuel supply and carburetor performance. In summary, this invention offers the advantage of flexibly adjusting the carburetor flow rate, solving the problem that traditional carburetors cannot adjust the flow rate accurately and in real time according to operating conditions, which leads to reduced engine efficiency, increased fuel consumption, and even excessive exhaust emissions, thus affecting environmental performance.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figure 1-5 As shown, this utility model discloses an adjustable flow carburetor, including a carburetor body 6. An inlet pipe 1 is installed at the inlet end of the carburetor body 6. A flow meter 7 and a control valve 8 are installed on the inlet pipe 1. An iron cover 9 is fixed to the other end of the carburetor body 6 by screws. A float cover plate 2 is fixed to the top of the carburetor body 6 by screws. A float assembly 3 is installed on the float cover plate 2. A fuel filter 4 and a throttle assembly 5 are installed on the rear top side of the carburetor body 6. In use, this invention features a flow meter 7 and a control valve 8 installed on the fuel inlet pipe 1. The flow meter 7 monitors the fuel flow rate entering the carburetor body 6 in real time, ensuring accurate fuel supply. The control valve 8 adjusts the fuel supply according to actual needs, allowing for flexible adjustment of the carburetor flow rate. When fuel consumption causes the fuel level to drop, the float assembly 3 descends, opening the fuel inlet to allow fuel to flow in. When the fuel level rises, the float assembly 3 rises, closing the fuel inlet, ensuring the fuel quantity is maintained at an appropriate level. This ensures the engine receives the correct fuel ratio under different operating conditions, thereby improving engine power output and fuel economy, and reducing fuel consumption. Fuel waste and exhaust emissions; because a fuel filter 4 is installed on the top rear side of the carburetor body 6, the fuel filter 4 can effectively filter out impurities and particulate matter in the fuel, ensuring that the fuel entering the carburetor is pure and free of impurities, preventing the small channels inside the carburetor from being blocked due to excessive impurities in the fuel, affecting the normal fuel supply and the performance of the carburetor; in summary, this utility model has the beneficial effect of flexibly adjusting the carburetor flow rate, solving the problem that traditional carburetors cannot adjust the flow rate in real time and accurately according to the working conditions, which leads to a decrease in engine working efficiency, an increase in fuel consumption, and even excessive exhaust emissions, affecting environmental performance.

[0021] Preferably, an air conditioning sleeve 10 is fixedly installed on the carburetor body 6, and an air conditioning screw 11 is installed on the air conditioning sleeve 10. Since the air conditioning sleeve 10 is equipped with the air conditioning screw 11, rotating the air conditioning screw 11 can change the opening of the air conditioning sleeve 10. When the engine is operating under low load, reducing the opening of the air conditioning sleeve 10 reduces the amount of air entering the carburetor, making the fuel-air mixture richer and ensuring stable engine operation. When the engine is operating under high load, increasing the opening of the air conditioning sleeve 10 increases the amount of air entering the carburetor, making the fuel-air mixture leaner and improving engine power output. This effectively allows for flexible adjustment of the fuel-air mixture ratio and optimizes combustion.

[0022] Preferably, an idle speed adjusting sleeve 13 is fixedly provided on the carburetor body 6, and an idle speed adjusting screw 12 is installed on the idle speed adjusting sleeve 13. Since the idle speed adjusting sleeve 13 is equipped with the idle speed adjusting screw 12, rotating the idle speed adjusting screw 12 can change the opening of the idle speed adjusting sleeve 13, thereby adjusting the fuel supply of the carburetor under idling conditions.

[0023] Preferably, a conical venturi tube 14 with a cone angle of 12°-15° is provided above the throttle assembly 5. When air flows through the conical venturi tube 14, the tube diameter gradually decreases and the air velocity gradually increases, forming a negative pressure area. This negative pressure effect can enhance the air suction capacity, thereby enabling the carburetor to draw in more air.

[0024] Preferably, the float assembly 3 includes a float adjusting column 31, a float needle valve 32 installed at the bottom of the float adjusting column 31, and a float body 33 installed at the bottom of the float needle valve 32. The float body 33 is suspended in the fuel. Rotating the float adjusting column 31 adjusts the position of the float body 33, which plays a role in precise control of the fuel level. By opening and closing the float needle valve 32, the stability of the fuel level can be maintained.

[0025] Preferably, the throttle assembly 5 includes a threaded knob 51, a needle valve 53 mounted at the bottom of the threaded knob 51, a throttle valve 52 sleeved on the needle valve 53, and a valve seat 54 located below and connected to the throttle valve 52. Since the throttle valve 52 is sleeved on the needle valve 53, adjusting its opening controls the airflow into the carburetor; rotating the threaded knob 51 adjusts the position of the needle valve 53, achieving the beneficial effect of precisely controlling the carburetor flow.

[0026] Preferably, the inlet end of the carburetor body 6 is provided with a fuel inlet groove 61, and the upper surface of the carburetor body 6 is equipped with a throttle chamber 62 and a float chamber 63. The fuel inlet groove 61 at the inlet end of the carburetor body 6 facilitates the entry of fuel.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
