Abstract
The utility model relates to an electronic injection motorbike air damper which comprises an air dumper body and an air dumper cover. An air dumper valve is arranged in the air dumper body and connected with an air dumper pull rod. An air dumper spring is sleeved outside the air dumper pull rod. A cavity is formed in the lower end of the air dumper valve. Magnetic steel is arranged in the cavity in a matched mode. A Hall element is arranged on the portion, corresponding to the magnetic steel, of the lower end of the air dumper body. A signal outgoing line is connected with the Hall element. According to the structure, when the opening degrees of the air dumper are different, the distances between the magnetic steel of the air dumper valve and the Hall element arranged of the air dumper valve are different, the magnetic field intensity detected by the Hall element is different, and then the electric potential difference is generated between the two ends of the Hall element. A signal is generated by the electric potential difference and sent to an ECU and an order is sent by the ECU according to the working conditions, so that the oil spraying time and the oil spraying volume of an oil sprayer are adjusted. The electronic injection motorbike air damper is simple in production technology, low in production cost, free of mechanical abrasion in use and capable of prolonging the service life of the air dumper and improving the accuracy of control.
Description
Technical field
The utility model relates to motorcycle with electronic fuel injection system accessory field, relates in particular to the motorcycle with electronic fuel injection system closure that uses on a kind of motorcycle with electronic fuel injection system.
Background technique
Raising along with environmental protection and energy-conservation requirement, original Carburetor fuel feeding precision can't resist harsh now environmental regulation, China has done further control (requirement reaches state III, state IV emission standard) to the exhaust emissions of all motorcycles again in addition, so motorcycle adopts closure more energy-conservation, more environmental protection to replace the trend that existing Carburetor has become a kind of certainty.
A kind of motorcycle with electronic fuel injection system closure is disclosed in the China Patent No. CN202273764U specification, this closure utilizes the throttle rod frequency signal different with the electromagnetic induction generation between the coil, for ECU provides comparatively accurate output signal, thereby regulate oil spout speed and the injection time of oil sprayer, this closure is applicable in the motorcycle electric spraying system, have preferable effects of energy saving and emission reduction, but this closure preparation process more complicated, the cost of production height.
The model utility content
The purpose of this utility model provides that a kind of production technology is simple, and cost of production is low, and measurement signal is the motorcycle with electronic fuel injection system closure accurately.
The technical solution of the utility model is a kind of motorcycle with electronic fuel injection system closure, comprise throttle body and solar term door closure, be provided with throttler valve in the throttle body, throttler valve is connected with throttle rod, throttle rod is arranged with the closure spring outward, and described throttler valve lower end is provided with a cavity, and coupling is provided with magnet steel in the described cavity, throttle body lower end and magnet steel opposite position are provided with Hall element, are connected with the signal lighting outlet on the described Hall element.
Useful technique effect of the present utility model is: the motorcycle with electronic fuel injection system closure that adopts this structure, aperture difference when throttler valve, magnet steel on the throttler valve and the distance between the Hall element are then different, the detected magnetic intensity of Hall element is then different, the Hall element two ends form potential difference then, potential difference forms signal and sends ECU to, ECU sends instruction according to operating mode (as idling) again and regulates oil sprayer injection time and oil spout size, the utility model production technology is simple, cost of production is low, does not have the machinery wearing and tearing during use, does not have the bad connection phenomenon and exists, prolong the closure life-span, improved the accuracy of control.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1, throttle body; 2, solar term door closure; 3, closure spring; 4, throttler valve; 5, signal lighting outlet; 6, Hall element; 7, magnet steel; 8, throttle rod; 9, circuit board; 10, collar.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of motorcycle with electronic fuel injection system closure as shown in Figure 1, comprise throttle body 1 and solar term door closure 2, be provided with throttler valve 4 in the throttle body 1, throttler valve 4 is connected with throttle rod 8, be arranged with closure spring 3 outside the throttle rod 8, described throttler valve 4 lower ends are provided with a cavity, and coupling is provided with magnet steel 7 in the described cavity, throttle body 1 lower end and magnet steel 7 opposite positions are provided with Hall element 6, are connected with signal lighting outlet 5 on the described Hall element 6.Adopt the motorcycle with electronic fuel injection system closure of this structure, aperture difference when throttler valve 4, magnet steel 7 on the throttler valve 4 and the distance between the Hall element 6 are then different, Hall element 6 detected magnetic intensities are then different, Hall element 6 two ends form potential difference then, potential difference forms signal and sends ECU to by signal lighting outlet 5, ECU sends instruction according to operating mode (as idling) again and regulates oil sprayer injection time and oil spout size, the utility model production technology is simple, cost of production is low, does not have the machinery wearing and tearing during use, does not have the bad connection phenomenon and exists, prolong the closure life-span, improved the accuracy of control.
Further, described cavity is the cuboid cavity, and described magnet steel 7 is shaped as the cuboid with this cavity coupling.Be more preferably, described magnet steel 7 drift angles are fillet.Magnet steel 7 drift angles of cuboid are carried out rounding, convenient in assembling, and can not produce scuffing or gouge to cavity.
Further, described throttle body 1 lower end is provided with a groove that Hall element 6 is installed.Because what throttle body 1 adopted in the ordinary course of things is aluminium material, and aluminium material has shield effectiveness to magnetic field, can the magnetic intensity that Hall element 6 detects not exerted an influence, so can directly fitting, Hall element 6 is fixed in the groove of throttle body 1 lower end.
Further, described throttle rod 8 leans by a collar 10 with throttler valve 4 lower ends.In the time of pulling throttle rod 8 and the collar 10 that leans of throttler valve 4 will to drive throttler valve 4 mobile together, the aperture adjustment of realization throttler valve 4.
Be more preferably, described throttle body 1 lower end also is equipped with the circuit board 9 of fixed signal lighting outlet 5.Because Hall element 6 volumes are less, generally be to connect thinner lighting outlet at Hall element 6 earlier, and then with the lighting outlet overstriking, but thinner lighting outlet is owing to reason ratios such as vibrations are easier to damage, so install and fix the circuit board 9 of thin end lighting outlet in throttle body 1 lower end, guarantee that this motorcycle with electronic fuel injection system closure is not fragile.
