Description
Technical field
The utility model relates to a kind of experimental provision of automobile step motor type IACV (Idle Air Control Valve).
Background technology
The function of auto idle speed operation valve (isc valve) is working temperature according to engine and load, is automatically controlled the air quantity delivered under idling operation, maintain engine with stable idle running by Engine ECU.At present, the idle speed controller that automobile adopts has various ways, and wherein step motor type IACV (Idle Air Control Valve) is most widely used general.
And step motor type IACV (Idle Air Control Valve) is made up of stepper motor, screw body, valve rod and operation valve, valve rod and operation valve make one.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 step machine operation, to stator coil transport pulse voltage.The power-up sequence (phase place) of stator coil is different, and the rotation direction of stepper motor is just different; When inputting the pulse of some in certain sequence, stepper motor just turns over certain angle to a direction, and rotational angle depends on the quantity of input pulse.The rotary motion of stepping motor rotor is become the rectilinear motion of valve rod by screw body, the position of valve rod and operation valve, also just determines the air quantity delivered under engine idling condition.
Fig. 1 is the control circuit of certain vehicle step motor type IACV (Idle Air Control Valve).According to Fig. 1, when ignition switch closes, the adhesive of EFI main relay contacts, battery feed arrives B1 and the B2 terminal of IACV (Idle Air Control Valve) (i.e. isc valve) ,+B of Engine ECU and+B1 terminal through EFI main relay; By B1 terminal 1,3 phase, two coil power supplies to stepper motor, B2 terminal is to 2,4 phase, two coil power supplies.4 coils are connected respectively by the ISC1 terminal of terminal S1, S2, S3, S4 and Engine ECU, ISC2 terminal, ISC3 terminal, ISC4 terminal, and Engine ECU controls the bonding loop of each coil, to control the work of IACV (Idle Air Control Valve) (isc valve).
Utility model content
The utility model object is the experimental provision that the defect existed for prior art provides a kind of automobile step motor type IACV (Idle Air Control Valve).
The utility model for achieving the above object, adopt following technical scheme: a kind of experimental provision of automobile step motor type IACV (Idle Air Control Valve), comprise accumulator, its positive terminal is connected with the coil of normally opened relay by power switch, and is connected to the negative pole end of accumulator by this coil; The moving contact of described normally opened relay is extremely connected with described accumulator positive, and its stationary contact is connected with the B1 terminal on the wiring harness interface of step motor type IACV (Idle Air Control Valve) and B2 terminal respectively; S1 terminal on the wiring harness interface of described step motor type IACV (Idle Air Control Valve), S2 terminal, S3 terminal and S4 terminal are connected on the negative pole end of accumulator respectively by corresponding gauge tap; The control output end of described step motor type IACV (Idle Air Control Valve) is connected to by the screw mandrel be connected with stepping motor rotor on the pointer on angle dial.
Further, described angle dial is flexibly connected with the support of setting, and freely rotates relative to described support.
The beneficial effects of the utility model: this experimental provision structure is simple, safe and reliable, easy to operate, pointer clearly can indicate the direction and angle of rotating, and shows very directly perceived.
Accompanying drawing explanation
Fig. 1 is the control circuit figure of certain vehicle step motor type IACV (Idle Air Control Valve).
Fig. 2 is the fundamental diagram of automobile step motor type IACV (Idle Air Control Valve) of the present utility model.
Embodiment
Shown in Fig. 2, be the experimental provision of a kind of automobile step motor type IACV (Idle Air Control Valve) of the present utility model, comprise accumulator 1, its positive terminal is connected with the coil of normally opened relay 3 by power switch 2, and is connected to the negative pole end of accumulator 1 by this coil; The moving contact of described normally opened relay 3 is connected with described accumulator 1 positive terminal, and its stationary contact is connected with the B1 terminal on the wiring harness interface 8 of step motor type IACV (Idle Air Control Valve) 9 and B2 terminal respectively; S1 terminal on the wiring harness interface 8 of described step motor type IACV (Idle Air Control Valve) 9, S2 terminal, S3 terminal and S4 terminal are connected on the negative pole end of accumulator 1 respectively by corresponding gauge tap (K4, K5, K6, K7 namely in figure); The control output end of described step motor type IACV (Idle Air Control Valve) 9 is connected to by the screw mandrel 10 be connected with stepping motor rotor on the pointer 12 on angle dial 11.
In Fig. 2, the screw mandrel 10 be connected with rotor and pointer 12 are connected, and are furnished with angle dial 11 before pointer 12, and angle dial 11 is flexibly connected with the support 13 arranged, and freely can rotate relative to this support 13.When testing beginning, 0 scale of angle dial 11 can be aimed at pointer 12, be convenient to observation when testing and calculating; Gauge tap K4, K5, K6, K7 simulated engine ECU of each phase control stepper motor.When ignition switch closes, the gauge tap of each phase presses order closed, the disconnection successively of K4, K5, K6, K7 or K7, K6, K5, K4, screw mandrel 10 and pointer 12 will turn over certain angle by a direction, and rotation is discontinuous, consistent with the operating frequency of gauge tap, thus clearly show very much principle of work and the course of work of step motor type IACV (Idle Air Control Valve).
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
