Abstract
The utility model relates to a carburetor, which comprises a body (2), a throttle (10) arranged on the upper part of the body, an oil cup arranged on the lower part of the body and an slow-running nozzle tip (3) positioned inside the oil cup and arranged on the body, wherein, the slow-running nozzle tip is provided with an orifice (18), a foam hole (12) and an oil inlet hole (17) which are communicated with a central hole (13). An oil storage cavity (16) is arranged between the slow-running nozzle tip (3) and the body of the carburetor. The oil storage cavity is positioned between the foam hole (12) and the orifice (18) and is communicated with the central hole (13) through the oil inlet hole (17). When the engine starts, the generated negative pressure can inhale the fuel in the oil storage cavity into the engine and generate dense mixing gas, thereby making the engine easy to start.
Description
Technical field:
The utility model relates to the improvement of a kind of motorcycle engine with Carburetor.
Technical background:
At present, known motorcycle plunger type carburetor must use choke to improve the startability of motor.Because environmental requirement limited motorcycle idle exhaust emission mixture strength, make motor when ambient temperature is low slightly if do not use chock plate, the idling oil nozzle can not provide the mixed gas of enriching starting moment, causes engine cold to start difficulty, speed is slow.
Summary of the invention:
The purpose of this utility model is to overcome the shortcoming that engine cold starts difficulty, and a kind of Carburetor that can improve the motorcycle engine startability is provided.
The utility model comprises body (2), the throttle valve (10) on body (2) top, the lubricating cup of bottom (19) and be positioned at lubricating cup (19), and be loaded on idling oil nozzle (3) on the body (2), idling oil nozzle (3) is provided with metering-orifice (18), foam hole (12), go into oilhole (17) and center hole (13) communicates, it is characterized in that: be provided with a shoe cream room (16) between idling oil nozzle (3) and the Carburetor body (2), and shoe cream room (16) is positioned between foam hole (12) and the metering-orifice (18), communicates with center hole (13) by going into oilhole (17).
Be provided with a shoe cream room owing to the utility model is achieved in that at the body position of idling oil nozzle, shoe cream room is connected with metering-orifice by the oilhole of going on the idling oil nozzle, and the indoor fuel oil of carburettor float can enter shoe cream room by metering-orifice.The negative pressure that produces when engine start sucks motor with the fuel oil in the shoe cream room together with the fuel oil that the idling oil nozzle provides, just provide denseer mixed gas in the moment that starts to motor during engine start, make the motor normal ignition, help engine cold and start.And start rear engine and the fuel oil in the shoe cream room is all blotted, Carburetor recovers the normal fuel injection state, do not have bad phenomenon, and technology is simple.
