Embodiment
As shown in Figure 1, module of gas saving valve for mini engine of the present invention is made up of throttle body assembly 11 and the intake air temperature sensor 5, air inlet pressure sensor 8, throttle position sensor, stepper motor 6 and the pcb board 4 that are arranged in the housing.Throttle body assembly 11 bodies adopt casting aluminium material to make (other part of throttle body assembly 11 adopts stainless steel or other material to make), and housing adopts the highstrenghtpiston to make, be provided with seal ring between throttle body assembly 11 and the housing, being fixed by screw then links together.Can alleviate the weight of whole module like this, reduce manufacture cost.
In conjunction with shown in Figure 3, described housing is square, comprises housing assembly 10 and cover plate 1.Outer side wall respectively is provided with an engaging projection 20 around the described housing assembly 10, and clip 2 is fastened on cover plate 1 and engages between the projection 20, and housing assembly 10 and cover plate 1 are fixed together, and can carry out dismounting, maintenance very easily like this.The end face of housing assembly 10 sidewalls is provided with groove 16, and this groove 16 is embedded in seal ring 9.Extend to form surrounding edge 17 under all side direction of cover plate 1, this surrounding edge 17 is suitable with the shape of housing assembly 10, and housing assembly 10 is coated.Like this when cover plate 1 with after housing assembly 10 is fixedlyed connected, formed sealing configuration can prevent effectively that greasy dirt, water or other fouls from entering enclosure interior.Particularly when carwash, can prevent effectively that the high pressure water of high pressure water gun ejection from entering in the housing, cause internal sensor and circuit board damage, influence its reliability, simultaneously this sealing means maintainalbility can be good, and dismounting is very convenient.
Shown in Fig. 1,2, side in this housing assembly 10 is provided with stepper motor 6, the left end of the opposite side relative with stepper motor 6 is provided with throttle position sensor ceramic substrate 7, its right-hand member is provided with pcb board 4, throttle position sensor rotor 3 is arranged between throttle position sensor ceramic substrate 7 and the pcb board 4, and directly is connected with throttle plate pin.
Air inlet pressure sensor 8 pasters are at the back side of throttle position sensor ceramic substrate 7,
The other end of air inlet pressure sensor 8 is close on the bottom end of housing assembly 10, is provided with one with the bottom end of its corresponding shell assembly 10 and detects the hole, and this detection hole is connected with the closure air flue.The detection hole of described air inlet pressure sensor below also can be communicated with the force samples hole on being arranged on throttle body assembly 11, is used to gather the pressure at other positions of automobile with small output volumn.
The back side of pcb board 4 is provided with the intake air temperature sensor 5 that is electrically connected with it.Be provided with a mounting hole in the housing assembly 10, the thermistor of intake air temperature sensor 5 is installed in this hole and the closure air flue.Throttle position sensor ceramic substrate 7 is electrically connected by wire jumper and pcb board with air inlet pressure sensor 8, and stepper motor 6 is electrically connected with pcb board 4.Described stepper motor 6 also can be electrically connected with pcb board 4 by vibrationproof connector 12.The port one 8 that patches of described vibrationproof connector 12 is connected the obtuse angle angle that tilts between the body 19 with vibrationproof, form the oblique connector of socket.The angle that tilts is 120 °~150 °.Can reduce installing space like this, simultaneously the exchange wiring of stepper motor is more prone to.
Described housing assembly 10 and pcb board 4 corresponding side outer ends are directly made the standard male end socket of one 12 contact pin by the method for quadric injection mould, and as input/output interface 21, this interface 21 is electrically connected with pcb board 4.The user just can be connected with client end is convenient by the female end of a standard, and interface is very succinct, convenient.
In another embodiment of the present invention, also can adopt another mode of execution, with 6 cancellations of the stepper motor in the housing assembly 10, other structure is constant in the promptly described in front module of gas saving valve for mini engine.Because some national client for cost or otherwise consideration, requires to remove stepper motor 6.In fact, the effect of stepper motor 6 mainly is to be in closed condition when main airway, be that the driver is not when stepping on throttle, make the motor still can be in running order, perhaps working as the driver need start car by using car key, rather than the mode of stepping on the gas, ECU can pass through control step motor opening throttle bypass air flue, makes motor have enough air to start.And after removing stepper motor, when motor is in idling mode or needs cold start-up, can pass through some valves relevant with motor, the control motor reaches requirement.Certainly, the performance of this sample car may than the electric injection system poor accuracy that adopts the step motor control bypass some, also less better at aspect of performance.But there is certain reduction the cost aspect.
Existing throttle position sensor generally comprises three parts: shell, rotor, ceramic substrate.In order to reach the purpose that reduces closure module volume, the present invention is with the shell cancellation of throttle position sensor, throttle position sensor ceramic substrate 7 directly passes through glue or screw in housing assembly 10, and throttle position sensor rotor 3 is fixed together by lock screw or laser bonding with throttle plate pin.Equally, air inlet pressure sensor 8 and intake air temperature sensor 5 also are provided with shell no longer separately.
As shown in Figure 4, described throttle body assembly 10 is provided with the interface 14 that is connected with follow-up intake manifold 26, and the axial of this interface 14 parallels with the housing side at input/output interface 21 places.The interface 14 that described with follow-up intake manifold 26 is connected is provided with adpting flange 22, is formed for the flange-type connection interface of straddle type motorcycle.Also be provided with groove 23 on the interface 14 that described with follow-up intake manifold 26 is connected, be formed for the rubber hose formula connection interface of pedal motorcycle.Therefore, module of gas saving valve for mini engine of the present invention is used for existing motorcycle, when substituting Carburetor used on the motorcycle, can cover this two kinds of Placements fully, need not to change other part, has stronger compatibility.
One ECU (Electrical Control Unit) (ECU) can be set on the described pcb board 4.Module of gas saving valve for mini engine of the present invention sends the open angle about inlet condition and closure valve block to install on the pcb board 4 ECU chip by sensor, and then controls corresponding injection system by ECU.ECU is also by 1 final controlling element, when promptly stepper motor 6 is controlled idling and the air mass flow during cold start-up.
Module of gas saving valve for mini engine of the present invention has the integrated level height, compact conformation, and volume is little, Cost is low, and compatible good characteristics can directly apply to motorcycle and replace carburetor, and can be used for little The discharge capacity automobile.
