Above-mentioned digital motor oil-saving clarifier controller, the output terminal of described tonifying Qi solenoid valve is equipped with the secondary-atomizing modulating valve.
Above-mentioned digital motor oil-saving clarifier controller, described control panel circuit comprises two monostable triggers, this trigger of input carried out the shaping processing after 4 pin of first described monostable trigger were accepted vehicle speed signal, offer 12 pin of second described trigger then by the 6th pin, on the output circuit of the 10th pin of second described trigger, be equipped with by after resistance and the diode parallel connection with the reception comparison circuit of the state discriminator circuit of capacitances in series and operational amplifier and control idling solenoid valve and tonifying Qi solenoid valve, the triode inverter circuit of control sensitive switch also is housed on 13 pin of described monostable trigger.
This technological scheme has following beneficial effect:
1. can fuel-economizing and tonifying Qi, controller is connected on two lines on the spark coil, and the A line is a positive source, and the B line is the spark coil negative pole, is used for detecting firing pulse, i.e. engine speed.
When engine speed surpasses per minute 1200 commentaries on classics, slow down suddenly, make the sensitive switch closure, the E end ground connection of controller, at this moment controller stops, to the idling solenoid valve, both blocked the idling fuel oil of Carburetor, controller F end power supply simultaneously makes the energising of tonifying Qi electromagnetic valve coil, produce magnetic, overcome spring force, inhale left and move, make air lead to sucking pipe through aeration valve from air-core, to realize the purpose of tonifying Qi, reduce the degree of vacuum in the sucking pipe.
When engine speed is lower than per minute 1200 commentaries on classics or quickens sensitive switch is disconnected, controller E holds no longer ground connection, and at this moment controller recovers to stop simultaneously stopping tonifying Qi to the tonifying Qi solenoid valve to the idling solenoid valve.
Only when engine speed surpasses per minute 1200 and changes and carburetor throttle under the double action of idle position (sensitive switch closure), can realize that just forced idling blocks the purpose of fuel oil and tonifying Qi.
2. secondary-atomizing adjustment screw is housed in this product designs, how much adjust tonifying Qi according to the degree of wear of Carburetor for the wearing and tearing that overcome oil flow measuring hole of carburetor.
As long as engine operation, air will enter sucking pipe one-fraction air through adjusting screw from air-core, and the gasoline particle that mixes in the bump sucking pipe carries out secondary-atomizing, makes atomizing more complete.
This fuel economizer has also been considered, Carburetor all flows out from the oil mass hole because of the long-time fuel oil of boxes that uses, it is so-called that dripping water wears through rock, must wear and tear a little in the oil mass hole, the wearing and tearing of oil mass hole are big, and it is too much to suppress oil mass, the mixed gas overrich, in order to eliminate this phenomenon, designed secondary-atomizing tonifying Qi adjusting screw.According to the degree of wear difference of Carburetor, what of tonifying Qi are adjusted by adjusting screw, and cover the gasoline particle of this sub-fraction air with mixed gas in the very fast speed bump sucking pipe, carry out oil gas mixing second time, make atomizing more abundant.
Accompanying drawing 1 is the structural representation of this product.

Further specify below in conjunction with accompanying drawing:
Embodiment 1:
Digital motor oil-saving clarifier controller, its composition comprises: spark coil 1, the control panel circuit 2 that is attached thereto, the output circuit D of described control panel links to each other with idling solenoid valve 3, the output circuit E of described control panel links to each other with sensitive switch 7, the output circuit F of described control panel links to each other with the magnetic control coil of tonifying Qi solenoid valve 5, and a side of the spool of described solenoid valve 5 has gas supplementing opening 4, and the outlet of described tonifying Qi solenoid valve 5 communicates with sucking pipe 8.
Embodiment 2:
Above-mentioned digital motor oil-saving clarifier controller, the output terminal of described tonifying Qi solenoid valve is equipped with secondary-atomizing modulating valve 6, comprises valve body and the adjustment bolt that is installed in the described valve body.
Embodiment 3:
The effect of this controller is during greater than specific speed, to close the idling solenoid valve in the speed of a motor vehicle, opens the tonifying Qi solenoid valve.Keep quiescent value when the speed of a motor vehicle is lower than this specific speed, that is: open the idling solenoid valve, close the tonifying Qi solenoid valve.This controller is the control that is subjected to the Carburetor sensitive switch.When sensitive switch was closed, controller was just effective.When sensitive switch disconnected, controller was invalid, and remained on static position.
Above-mentioned functions is reached by monostable trigger.A two monostable trigger chip MCI4538 of this controller.4 pin of one of them monostable NIA receive the vehicle speed pulse signal, and the vehicle speed pulse signal are carried out shaping handle, and so just can guarantee another monostable NIB is carried out stable triggering.
12 pin of monostable NIB are accepted the trigger impulse of 6 pin of monostable NIA.This monostable NIB be can heavily trigger monostable.When cycle of trigger impulse during greater than monostable cycle of this monostable NIB, 10 pin of this monostable NIB are not exported pulse, but export a fixing high level.When the triggering frequency was lower than a characteristic frequency, by dried trigger interval lengthening, the monostable cycle, then 10 pin were exported monostable pulse less than trigger interval.R3, V5, C5 component frequency state discriminator circuit.
When 10 pin were high level, V5 added not conducting of backward voltage, and 10 pin charge to C5 by R5, and charging time constant is R5C5, was worth greatlyyer, and C5 charging is slower.When 10 pin were low level 0V, V5 added the forward voltage conducting, and C5 discharges by V5, and the time constant of discharge very little (forward resistance of V5 is very little) bleeds off the electric charge on the C5 rapidly.
This shows that as long as 10 pin output arteries and veins goes out, then capacitor C 5 is just filled less than sufficiently high level value forever.Have only when the fixing high level of 10 pin output just capacitor C 5 be flushed to enough high level.
