Abstract
The utility model discloses a throttle valve for a motorcycle with an electrical fuel injection system, which comprises a body (1) and an air inlet channel (2), wherein the side wall of the middle part of the body (1) is symmetrically provided with axle holes (3), and the front end of the body (1) is provided with an annular groove (4). The body (1) near the annular groove (4) is connected with a negative pressure detection tube (5) communicated with the air inlet channel (2). The outer wall of the body (1) is provided with an air supply channel (6) respectively communicated with the front end and the back end of the air inlet channel (2), and the air supply channel (6) along a radial direction is provided with an air conditioning pipe (7) communicated with the air supply channel. The outer sides of the axle holes (3) on one side of the body (1) are provided with oiling flanges (8), and the outer sides of the axle holes (3) on the other side are provided with sensor flanges (9). The utility model has the advantages of good interchangeability, accurate control to idle speed working conditions, reasonable design, simple structure, easy production, good working effect, etc.
Description
Technical field
The utility model relates to a kind of motorcycle fuel ejection control device, particularly motorcycle with electronic fuel injection system throttler valve.
Background technique
At present, the structure of general motorcycle with electronic fuel injection system throttler valve is: symmetry has axis hole on the sidewall at body middle part, and the body front end has and the engine cylinder head flange connecting.Is connected firmly because body and cylinder head adopt, not only interchangeability is poor, and because of the transmission of heat energy makes body temperature very high, and easy generation bubble during fuel evaporation makes the fuel injection quantity minimizing in the nozzle and in the oil duct, and it is undesired to cause motorcycle to start easily, the working condition instability.In addition, throttle plate pin radially passes the axis hole of body, its two ends are equipped with throttle control mechanism and position transducer respectively, because throttle control mechanism adopts coaxial the connection with position transducer, when the motorcycle idling, regulate throttle control mechanism, position transducer is also driven, and causes system's reflection that error is arranged.
The model utility content
At the defective and the deficiency of prior art, the purpose of this utility model is to provide a kind of and can adopts flexible pipe to be connected, idling operation is controlled accurate motorcycle with electronic fuel injection system throttler valve with engine cylinder head.
The technical solution of the utility model is as follows: a kind of motorcycle with electronic fuel injection system throttler valve, comprise body and intake duct, symmetry has axis hole on the sidewall at body middle part, its key is: described body front end is provided with annular groove, is connected to the negative pressure testing tube that communicates with intake duct on the body on annular groove next door; The body outer wall is provided with the air supply passage that is communicated with the intake duct rear and front end respectively, and air supply passage directly upwards has the air conditioning pipe that is communicated with it; The axis hole outside of described body one side is connected to the oiling flange, and the axis hole outside of opposite side is connected to the sensor flange.
Described air supply passage is made of gas-entered passageway and outlet passageway, and gas-entered passageway and outlet passageway misplace in the axial direction.
Annular groove and flexible pipe and the engine cylinder head of the utility model by the body front end is flexible coupling, replacing original flange connects firmly, thereby solved that hard connection interchangeability is poor, easily produced bubble in the nozzle and in the oil duct during fuel evaporation, the problem that fuel injection quantity is reduced, make that the motorcycle starting is normal, working condition is stable; After throttle control mechanism and position transducer regulate, be fixed on the body by oiling flange and sensor flange respectively, the control of operating mode is finished by the air inflow of regulating air supply passage during idling, promptly in the air conditioning pipe, establish an adjusting screw, can control the degree of depth in the screw precession air conditioning pipe by manual or stepper motor, thereby reach accurate control idling operation.In addition, the negative pressure testing tube is connected with pressure transducer, measures negative pressure jointly, can be under varying environment, and different altitudes is optimized system.
The utlity model has advantages such as reasonable in design, simple in structure, that enforcement is easy, the work effect is good.

Embodiment
Please see Figure 1, Fig. 2, Fig. 3 and Fig. 4, the utility model comprises body 1 and intake duct 2, opposite side at body 1 middle part has axis hole 3, and described body 1 front end is provided with annular groove 4, is connected to the negative pressure testing tube 5 that communicates with intake duct 2 on the body 1 on annular groove 4 next doors; Body 1 outer wall is provided with the air supply passage 6 that is communicated with intake duct 2 rear and front ends respectively, and air supply passage 6 footpaths upwards have the air conditioning pipe 7 that is communicated with it; Axis hole 3 outsides of described body 1 one sides are connected to oiling flange 8, and axis hole 3 outsides of opposite side are connected to sensor flange 9.
Also can further find out from Fig. 4: air supply passage 6 is made of gas-entered passageway 6a and outlet passageway 6b, and gas-entered passageway 6a and outlet passageway 6b misplace in the axial direction.
Claims (2)
1, a kind of motorcycle with electronic fuel injection system throttler valve, comprise body (1) and intake duct (2), symmetry has axis hole (3) on the sidewall at body (1) middle part, it is characterized in that: described body (1) front end is provided with annular groove (4), is connected to the negative pressure testing tube (5) that communicates with intake duct (2) on the body (1) on annular groove (4) next door; Body (1) outer wall is provided with the air supply passage (6) that is communicated with intake duct (2) rear and front end respectively, and air supply passage (6) footpath upwards has the air conditioning pipe (7) that is communicated with it; Axis hole (3) outside of described body (1) one side is connected to oiling flange (8), and the axis hole of opposite side (3) outside is connected to sensor flange (9).
