Description
Technical field
The present invention relates to a kind of Carburetor.
Background technique
Existing, the carburetor engine fuel feeding is to utilize the trunnion that is arranged on the intake valve top, produces negative pressure when air communication is crossed trunnion, and gasoline from the continuous sucking-off of main nozzle, is got into engine intake manifold, flows into cylinder again.The effect of Carburetor is exactly with the gasoline of some and air mixing, so that normal working of engine.If do not have enough fuel oils and air mixing, motor will turn round under " oil-poor " state so, and this will make engine stoping operation, also may damage motor.If excessive fuel oil and air mixing are arranged; Motor will turn round under " rich oil " state so, and this also will make engine stoping operation (Carburetor oil spilling), produce a large amount of cigarettes when perhaps turning round; Perhaps operational situation abominable (problem, stall take place easily) perhaps is the waste fuel oil at least.Therefore Carburetor is to be responsible for blended fuel oil and air, and having reached the required oil-gas ratin of normal working of engine is air fuel ratio.
Carburetor is mainly by float chamber, trunnion, main jet pipe and closure or the like.When motorcycle makes in road, startup, idling, middle load are generally arranged and the four kinds of operating modes of loading greatly.The variation of motorcycle working condition mainly shows as the continuous variation of the running velocity and the power-assisted of going.This variation will influence the rotating speed and the load of motor.And a good Carburetor needs and can supply with the fuel mixture of variable concentrations in time, exactly according to the various working conditions of motor.At present; The Carburetor that uses on most of motorcycles; Its closure is connected with handle through steel cable with throttle; By driver's operation handle or the aperture of footstep mechanism control closure and the size of throttle, the concentration of the needed fuel mixture of motor is to rely on the sensation of driver and experience to regulate, and is difficult to accomplish to supply with timely and accurately according to the various working conditions of motor the fuel mixture of variable concentrations.Because the acceleration and the deceleration of driver's direct control handle pulling valve and spindle control vehicle, will cause the vehicle acceleration too fast or slow down too fastly if the fuel delivery of motor is incorrect, make that easily passengers inside the car drop down.Prevent this and want accident to take place and to monitor in real time the running process of vehicle that according to exercising the open accurate fuel delivery of control motor in real time, the acceleration that makes vehicle and moderating process are in the safety range of permission.
Therefore, how to provide that a kind of can be respectively to regulate the oil inlet quantity that gets into trunnion through accurate control closure plunger and spindle be the technical problem that those skilled in the art need to be resolved hurrily with air inflow with the intelligent Carburetor of the division control type of realizing suitable air fuel ratio.
