Motorcycle carburetor

Abstract

The invention relates to the technical field of machinery, in particular to a motorcycle carburetor which includes a carburetor body with an air inlet. An air supplement device is arranged on the carburetor body, and an auxiliary air supplement device matched with the air supplement device is further arranged on the carburetor body. According to the motorcycle carburetor, sufficient air supplementair input can be ensured, a slender valve needle is adopted to fit an air valve mouth, and the fit length between the valve needle and the air valve mouth is longer, so that an air supplement curve is easier and more accurate to set; a valve needle flat gasket is arranged between the air valve mouth and the valve needle, so that the air valve mouth is not in direct contact with the valve needle,and the jamming phenomenon can be effectively eliminated; because an inclined plane is the inclined plane which is inclined in the mode of the position in the direction close to the air inlet higher than the position in the direction away from the air inlet, the influence of the intake air flow on the diffusion of mixed air sprayed by a main injection nozzle is minimized, the atomization efficiency is improved, and the engine combustion is more fully; and fuel and air can be stably supplied when a motorcycle accelerates rapidly, so that the working efficiency of an engine is improved.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a motorcycle carburetor. Background technique [0002] The carburetor is a mechanical device that mixes a certain proportion of gasoline with air under the vacuum generated by the engine. The common motorcycle carburetor of the prior art has the deficiency that the air-fuel ratio of air and gasoline cannot reach the ideal state, and the gasoline is discharged from the exhaust pipe if it cannot be fully burned, resulting in high fuel consumption and waste of resources, and the gaseous pollution discharged from the exhaust pipe Excessive substances such as carbon monoxide, hydrocarbons and carbon oxides will cause great pollution to the environment. In addition, when gasoline is not burned cleanly, carbon deposits will be generated in the engine such as spark plugs, valves and other related parts, shortening their service life.

AI Technical Summary

Problems solved by technology

The common motorcycle carburetor of the prior art has the deficiency that the air-fuel ratio of air and gasoline cannot reach the ideal state, and the gasoline is discharged from the exhaust pipe if it cannot be fully burned, resulting in high fuel consumption and waste of resources, and the gaseous pollution discharged from the exhaust pipe Excessive substances such as carbon monoxide, hydrocarbons and carbon oxides will cause great pollution to the environment. In addition, when gasoline is not burned cleanly, carbon deposits will be generated in the engine such as spark plugs, valves and other related parts, shortening their service life.

[0003] Moreover, the existing motorcycle carburetors are rarely provided with an air supply device. Even if there is an air supply device, the electronic control air supply method is often used to work. The air supply device is mainly composed of electronic components and electrical components, so there are the following Disadvantages: relatively high cost; high failure rate, short service life, not easy to maintain, professional repairs are required for problems

[0004] In order to avoid these defects, some manufacturers have developed a mechanical air supply carburetor, which is relatively low in cost, and the transmission path and component linkage relationship are relatively clear, easy to check, and easy to maintain. However, the air supply cable of this mechanical air supply carburetor The location of the plunger throttle cable is arranged in front of one another. When it is installed on a motorcycle and bent, one of them is easy to be lifted inadvertently or cause jamming

In addition, the air intake channel of the existing mechanical air supply carburetor is directly connected with the air supply valve seat and the air filter connection port of the shell by a rubber tube, so the rubber tube is easy to age and damage

The engine is not easy to start when the temperature is low, and it will stall when idling, and the acceleration is not smooth, and it is easy to stall
