Double-barrel carburetor

Abstract

The invention discloses a double-barrel carburetor, and relates to the technical field of carburetors. The double-barrel carburetor comprises a carburetor body and a pump cover mounted at the lower end of the carburetor body. A main oil pipe used for injecting oil is connected to the outer side of the pump cover. A plastic adjustment bolt is arranged on the side face of the carburetor body, and amain throttle valve shaft is mounted on the side face of the carburetor body and is located on the side close to the plastic adjustment bolt. By adoption of the design, when an engine works normally,only a main barrel works; when a load or the rotating speed reaches a certain degree or the air flow in the main barrel does not reach the standard, two barrels work at the same time to ensure normalwork of the engine under a large load; a balance valve and an airflow inductor are used in cooperation to keep the mixed air pressures in the two barrels balanced, the problem of air snatching of allcylinders when air inflows is avoided, and atomization of oil is facilitated; and a rubber sealing ring is additionally arranged, so that the air resisting efficiency is improved, the sealing performance of the carburetor body is improved, and accordingly, the power performance and economical efficiency of the engine are improved.

Description

technical field [0001] The invention relates to the technical field of painting, in particular to a double-chamber carburetor. Background technique [0002] At present, with the development of society, the improvement of people's living standards, and the continuous improvement of modern sports machinery, the general-purpose gasoline engine has been widely developed. Carburetor, as the precise core component of gasoline engine and gasoline generator, utilizes the kinetic energy of the inhaled air flow to realize the atomization of gasoline. The carburetor can automatically match the corresponding oil and gas concentration according to the requirements of different working conditions of the engine. , to output a corresponding amount of mixed gas, so it can be said that the carburetor is the "heart" of the engine. During the process of starting the vehicle to high speed, the throttle cable drives the rotary valve to rotate, and then gradually achieves the effect of the carbure...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a double-chamber carburetor to solve the above-mentioned problem in the background technology that when the engine has a high-power load or the speed reaches a certain level, the flow rate of the mixed gas in the chamber is different, which will cause the cylinders to enter the carburetor. The phenomenon of robbing each other during gas will affect the atomization efficiency at the same time, and the existing dual-chamber carburetor generally adopts integrated control for the control of the throttle valve, and the simultaneous work of the two chambers will increase economic waste. At the same time, the choke valves of the two chambers adopt an integrated control type, and the sealing effect needs to be improved, otherwise it is easy to cause the loss of gas and oil when the carburetor is not working
