Abstract
The utility model discloses a motorcycle electronic fuel injection throttle body, which comprises a valve body (1), wherein a central hole of the valve body (1) includes an inlet conical section (1a), a transition section (1b) and an outlet conical section (1c); the transition section (1b) is a unidiameter straight section and positioned between the inlet conical section (1a) and the outlet conical section (1c); both the inlet conical section (1a) and the outlet conical section (1c) are flared structures; the length of the inlet conical section (1a) ranges from 11mm to 17mm and the taper of the inlet conical section (1a) ranges from 5 degrees to 8 degrees; and the length of the outlet conical section (1c) ranges from 17mm to 23mm and the taper of the outlet conical section (1c) ranges from 3 degrees to 6 degrees. Through changing the structure of the central hole of the valve body, the motorcycle electronic fuel injection throttle body meets the requirements on air intake speed and quantity of small-displacement engines, and has the advantages of smart design, simple structure, easy processing, high university, and the like.
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.

Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1 and Figure 2, the center hole of electrospray throttle valve body valve body 1 is an air-flow path, and this center hole is by cone section 1a, changeover portion 1b and go out prostomum section 1c and form, and wherein changeover portion 1b is at cone section 1a and go out between the prostomum section 1c, changeover portion 1b is isodiametric straight section, and internal diameter is 30mm.Described cone section 1a is connected with empty filter, and this cone section 1a is the horn mouth structure, and little head end links to each other with changeover portion 1b.The length of described cone section 1a is 11～17mm, is preferably 14mm in the present embodiment; The tapering of relative valve body 1 axis of cone section 1a is 5～8 °, is preferably 6 ° in the present embodiment.Describedly go out prostomum section 1c and be connected with engine air inlet tube, this goes out prostomum section 1c and also is the horn mouth structure, and little head end links to each other with changeover portion 1b.The described length that goes out prostomum section 1c is 17～23mm, is preferably 20mm in the present embodiment; The tapering that goes out prostomum section 1c is 3～6 °, is preferably 4 ° in the present embodiment.All the other structures of the present utility model are same as the prior art, do not do at this and give unnecessary details.
Claims (3)
1. electric injection gas saving valve for motorcycle, has valve body (1), it is characterized in that: the center hole of described valve body (1) is by cone section (1a), changeover portion (1b) and go out prostomum section (1c) and form, wherein changeover portion (1b) is isodiametric straight section, and be positioned at cone section (1a) and go out between the prostomum section (1c), described cone section (1a) and go out prostomum section (1c) and be the horn mouth structure, and smaller diameter end is connected with changeover portion (1b), wherein the length of cone section (1a) is 11～17mm, tapering is 5～8 °, the length that goes out prostomum section (1c) is 17～23mm, and tapering is 3～6 °.
