Abstract
The utility model discloses an electrical control carburetor with two auxiliary air ducts, which relates to a motorcycle engine carburetor. A valve body of a duty ratio electromagnetic valve (3) is inserted in an installation hole of a valve seat (2), an air inlet channel (5) is arranged between an air inlet cavity (6) of the installation hole of the valve seat (2) and a hollow throat air inlet pipe (4), and an air outlet channel (8) is arranged between a mixed gas outlet (9) and an air outlet cavity (7) of the installation hole of the valve seat (2). The electrical control carburetor has simple and compact structure and convenient fabrication and assembly, and ensures that the motorcycle can easily reach the requirement of the Euro II emission standard. Combining with the catalyst technology of a silencer, the electrical control carburetor is easy to control the waste gas emission index of the motorcycle within the range of the Euro II emission standard.
Description
One, technical field
The utility model relates to engine and carburetor of motorcycle, especially a kind of electronic controlled carburetor that has two auxiliary ports and solenoid valve.
Two, background technique
The present engine and carburetor of motorcycle that uses, be generally the Carburetor of plunger type or equal vacuum diaphragm type, the fuel feeding curve of motorcycle carburetor is determined by the Carburetor configuration, fuel feeding tracing analysis from Carburetor, the desirable fuel delivery of Carburetor and air fuel ratio only account for about 40% of engine design speed range, and the speed range oil mass more than 60% of engine working process and air fuel ratio all are in overrich or rare excessively nonideality, cause occurring problem such as oil consumption and discharge amount of exhaust gas be excessive.
Three, summary of the invention
Order of the present utility model provides a kind of simple in structure, be provided with two auxiliary ports and duty solenoids at the Carburetor body, and the electronic control unit controls that duty solenoids is formed by single-chip microcomputer, enforcement reaches the effect that energy-saving and emission-reduction are put from the air fuel ratio of motion tracking correction Carburetor when guaranteeing or improving engine power performance.
Technological scheme that the purpose of this utility model adopts is, an end that comprises the body of Carburetor has trunnion suction tude, the other end that the mixed gas air outlet is arranged, body is provided with valve base, the valve base mounting hole has air-inlet cavity and outlet chamber, and duty solenoids, the valve body of its described duty solenoids inserts in the valve base mounting hole, between the air-inlet cavity of trunnion suction tude and valve base mounting hole gas-entered passageway is arranged, and between the outlet chamber of mixed gas air outlet and valve base mounting hole outlet passageway is arranged.
The utility model and electric control integrated system of carburetor integrate, be assemblied between the empty clear filter cleaner and suction tude of motorcycle engine, the signaling interface of duty solenoids is connected with the duty solenoids interface of ECU controller, by automatically controlled integrated system Carburetor is implemented the effect that the toxic emission that reaches reduction and control motorcycle was regulated and controlled to air fuel ratio, implement the optimization of emission controls by improving combustion and power performance.
The utlity model has simple and compact for structurely, make easy to assemblyly, can make motorcycle easily reach Europe II emission standard requirement, in conjunction with the catalyst technology of silencing apparatus, the toxic emission index with motorcycle is controlled within the III emission standard of Europe easily.
Four, description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
