The utility model discloses a motorcycle electric fuel injection throttle body, which has a valve body (1), and the central hole of the valve body (1) is composed of an inlet cone section (1a), a transition section (1b) and an outlet cone section ( 1c), wherein the transition section (1b) is a straight section of equal diameter, and is located between the inlet cone section (1a) and the outlet cone section (1c), and the inlet cone section (1a) and the outlet cone section (1c) Both are bell-mouth structures, wherein the length of the inlet cone section (1a) is 11-17mm, the taper is 5-8°, the length of the outlet cone section (1c) is 17-23mm, and the taper is 3-6°. The utility model meets the requirements of the air intake speed and air intake volume of the small displacement engine by changing the structure of the central hole of the valve body, and has the characteristics of ingenious design, simple structure, easy processing and strong versatility.
Description
Technical field
The utility model relates to a kind of motorcycle member, particularly the electrospray throttle valve body of motorcycle.
Background technique
The electrospray throttle valve body is the critical component of motorcycle electric control fuel oil jet system, be connected between sky filter and the engine air inlet tube, effect is the rotation angle by the closure valve block, controls the air inflow of motor, and the angle position signal of throttle plate pin is fed back to ECU (Electrical Control Unit).At present, throttle body commonly used be by its center hole as air-flow path to the motor air feed, the internal diameter of this air-flow path is big, and almost be isometrical, though air inflow is big, but it is slower that air communication is crossed the speed of throttle body, can only be applicable to large-duty engines such as 250ml, 400ml, can't satisfy the performance requirement of small displacement engine.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of electric injection gas saving valve for motorcycle, to satisfy the air inlet requirement of small displacement engine.
The technical solution of the utility model is as follows: a kind of electric injection gas saving valve for motorcycle, has valve body, its key is: the center hole of described valve body is by cone section, changeover portion and go out the prostomum section and form, wherein changeover portion is isodiametric straight section, and in the cone section and go out between the prostomum section, described cone section and go out the prostomum section and be the horn mouth structure, and smaller diameter end is connected with changeover portion, wherein the length of cone section is 11～17mm, tapering is 5～8 °, the length that goes out the prostomum section is 17～23mm, and tapering is 3～6 °.
The utility model makes the internal diameter of throttle body valve body into two and is horn mouth, middlely is isometrical section, and pass through accurate Calculation, optimize parameters such as two bell-mouthed length, tapering, when entering and flowing out valve body, the motor airflow flowing can strengthen flow velocity by throttle body from empty filter like this, satisfied the requirement of the quick air inlets of small displacement engine such as 175ml, 200ml, guaranteed air inflow abundance simultaneously to the motor supply.In addition, the horn mouth tapering at valve body center hole two ends is bigger, helps withdrawing pattern, can make things convenient for processing and fabricating.
As preferably, the length of described cone section is 14mm, and tapering is 6 °, and the length that goes out the prostomum section is 20mm, and tapering is 4 °; The internal diameter of described changeover portion is 30mm.
Beneficial effect: the utility model has satisfied the intake velocity and the air inflow requirement of small displacement engine by changing the structure of valve body center hole, has characteristics such as design is ingenious, simple in structure, easy processing, highly versatile.
