Description

Carburetor for motorcycle engine

Technical Field

The invention relates to the technical field of carburetors, in particular to a carburetor for a motorcycle engine.

Background

The carburetor is a mechanical device which mixes gasoline and air in a certain proportion under the action of vacuum generated by the operation of an engine. A carburetor is a precise mechanical device which utilizes the kinetic energy of the intake air flow to atomize gasoline. Its important role in the engine may be referred to as the engine's "heart". The complete device comprises a starting device, an idling device, a medium load device, a full load device and an accelerating device. The carburetor can automatically match corresponding concentration according to different working state requirements of the engine and output corresponding amount of mixed gas, and in order to enable the mixed gas to be uniformly mixed, the carburetor also has the effect of atomizing fuel oil so as to enable a machine to normally run.

When the existing carburetor of the motorcycle engine is used for cleaning the inside of the carburetor, a worker needs to disassemble the carburetor by screwing a plurality of groups of bolts to clean the inside of the carburetor, however, the bolts can rust and slide when being used for a long time, and the operation of the worker is inconvenient when the carburetor is disassembled and installed. In view of this, we propose a carburettor for a motorcycle engine.
