Description
Technical field
The present invention relates to a kind of experimental provision of automobile step motor type IAC.
Background technology
The function of auto idle speed control valve (isc valve) is the operating temperature and load according to engine, by Engine ECU certainly
Air quantity delivered under dynamic control idling operation, maintains engine to stablize idle running.At present, the idling control used on automobile
Device processed has a diversified forms, and wherein step motor type IAC is most widely used.
And step motor type IAC by stepper motor, screw body, valve rod and control valve group into, valve rod and control
Valve processed is formed integrally.Stepper motor is permanent-magnetic electric machine, is made up of rotor and stator, and rotor is permanent magnet, and stator is electromagnet.
During Engine ECU control stepper motor work, pulse voltage is conveyed to stator coil.The power-up sequence (phase) of stator coil is no
Together, the rotation direction of stepper motor is just different；When inputting a number of pulse in certain sequence, stepper motor is just to a certain
Direction turns over certain angle, and rotational angle depends on the quantity of input pulse.Screw body is by the rotation of stepping motor rotor
Motion is changed into the position of the linear motion of valve rod, valve rod and control valve, also just determines that the air under engine idling condition supplies
To amount.
Fig. 1 is the control circuit of certain vehicle step motor type IAC.It can be seen from Fig. 1, when ignition switch closes
When, EFI main relay contacts adhesives, battery feed reaches the B1 and B2 of IAC (i.e. isc valve) through EFI main relays
The terminal ,+B of Engine ECU and+B1 terminals；From B1 terminals to the 1 of stepper motor, 3 two coil power supplies of phase, B2 terminals are to 2,4
Two coil power supplies of phase.4 coils respectively by terminal S1, S2, S3, S4 and the ISC1 terminals of Engine ECU, ISC2 terminals,
ISC3 terminals, ISC4 terminals are connected, and Engine ECU controls the bonding loop of each coil, to control IAC (isc valve)
Work.
The content of the invention
The defects of the present invention seeks to exist for prior art, provides a kind of automobile step motor type IAC
Experimental provision.
The present invention to achieve the above object, adopts the following technical scheme that：A kind of automobile step motor type IAC
Experimental provision, including battery, its positive terminal is connected by the coil of power switch and normally opened relay, and is connected by the coil

On the negative pole end of battery；The control output end of the step motor type IAC passes through the silk that is connected with stepping motor rotor
Bar is connected on the pointer on angle dial.
Further, the angle dial is flexibly connected with the support set, and is freely rotated relative to the support.
Beneficial effects of the present invention：The experimental provision is simple in construction, safe and reliable, easy to operate, and pointer can be indicated clearly
The direction of rotation and angle, display are very directly perceived.
Brief description of the drawings
Fig. 1 is the electric operation control circuit figure of certain vehicle step motor type IAC.
Fig. 2 is the fundamental diagram of the automobile step motor type IAC of the present invention.
Embodiment
Shown in Fig. 2, for a kind of experimental provision of automobile step motor type IAC of the present invention, including battery 1,
Its positive terminal is connected by power switch 2 with the coil of normally opened relay 3, and the negative pole of battery 1 is connected to by the coil
End；The movable contact of the normally opened relay 3 is connected with the positive terminal of battery 1, and its stationary contact is idle with step motor type respectively
B1 terminals on the wiring harness interface 8 of fast control valve 9 connect with B2 terminals；The wire harness of the step motor type IAC 9 connects
S1 terminals, S2 terminals, S3 terminals and S4 terminals on mouthfuls 8 respectively by corresponding controlling switch (K4, K5, K6 i.e. in figure,
K7) it is connected on the negative pole end of battery 1；The control output end of the step motor type IAC 9 passes through electric with stepping
The connected screw mandrel 10 of machine rotor is connected on the pointer 12 on angle dial 11.
In Fig. 2, the screw mandrel 10 and pointer 12 that are connected with rotor are connected, and are disposed with angle dial before pointer 12
11, angle dial 11 is flexibly connected with the support 13 set, and can freely be rotated relative to the support 13.Start in experiment
When, 0 scale of angle dial 11 pointer 12 be can be directed at, observation and calculating during experiment are easy to；The controlling switch K4 of each phase,
K5, K6, K7 simulated engine ECU are controlled to stepper motor.When ignition switch closes, the controlling switch of each phase by K4,
K5, K6, K7 or K7, K6, K5, K4 order are closed, disconnected successively, and screw mandrel 10 and pointer 12 will be turned over necessarily by a direction
Angle, and rotate be discontinuous, consistent with the operating frequency of controlling switch, so as to which what is be apparent from shows step motor type
The operation principle and the course of work of IAC.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
