Description
The utility model relates to a kind of ignition mechanism, especially high-energy igniting device for vehicle.
Spark coil in the existing automobile igniter directly links to each other with distributor, therefore, and 1, when the output voltage of spark coil is unstable, directly influence the working life of distributor.When 2, spark coil is not worked, the counterelectromotive force that distributor produces has certain influence to spark coil, for example when the spark coil of automobile is not worked, if during the switch on of distributor, certain electric current is arranged in the spark coil, make distributor point produce patina, influence the working life of distributor on the one hand, when spark coil was worked, discharge current reduced on the other hand, and the power of ignition mechanism descends.
The purpose of this utility model is to overcome the problem that above-mentioned prior art exists, and counterelectromotive force interference in a kind of prevention ignition circuit is provided, and humidification is carried out fault and shown, and can bear the ignition mechanism that high-voltage pulse passes through in the high-voltage pulse of distributor.
The technological scheme that realizes the utility model purpose is: display tube, spark coil, distributor, powerful device that this ignition mechanism includes high voltage wire, can fault shows, powerful device is connected between spark coil and the display tube by high voltage wire, and the other end of display tube connects distributor by high voltage wire.
Described powerful device is by shell and be arranged on the induction amplification circuit that wherein diode D1, capacitor C 2, inductance L 3 compose in parallel and constitute.
The high voltage wire of this ignition mechanism is made of damping layer, the nichrome core and the external insulation layer that are wound on the damping layer.
Good effect of the present utility model is:
1, the technical solution of the utility model is isolated spark coil and distributor, is applicable to the ignition circuit of automobile.
2, the diode that is connected in parallel on inductance or electric capacity two ends in the powerful device can make high-voltage pulse pass through smoothly, and the counterelectromotive force that stops distributor to produce passes through.
3, because powerful device adopts inductance, electric capacity antiresonant circuit, has high pressure resonance accumulation of energy effect, under the effect of antiresonant circuit and display device, the amplitude of high-voltage pulse strengthens, can improve ignition effectiveness, increase power, automobile is started easily, mixed gas is fully burned, not only fuel-economizing but also reduce exhaust pollution.
4, the high voltage wire of ignition mechanism can bear high-voltage pulse and passes through, and has the characteristics high temperature resistant, that insulating property are good.
5, can carry out fault judgement according to the bright dark degree of display tube spark.
The explanation of accompanying drawing drawing.
Fig. 1 is embodiment's 1 circuit theory diagrams of the present utility model.
Fig. 2 is the A-A sectional view among Fig. 1.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The powerful device 2 of this ignition mechanism is by shell and is arranged on the induction amplification circuit that wherein diode D1, capacitor C 2, inductance L 3 compose in parallel and constitutes.Display tube 3 adopts explosion type febetron light beam electron tube, can improve ignition energy, if two ends add high pressure, the display tube conducting is also luminous.
Embodiment 1: see Fig. 1, this circuit is the ignition circuit of automobile.Be connected between spark coil 4 and the distributor 5 after powerful device 2 and display tube 3 series connection, powerful device 2 links to each other with spark coil 4 by high voltage wire 1, and display tube 3 links to each other with distributor 5 by high voltage wire 1, and like this, spark coil 4 and distributor 5 are isolated.Concrete working principle is as follows: the K3 that closes a switch, K4, the 12V storage battery power supply, winding that discharges and recharges to spark coil 4 by capacitor C 3 provides pulse signal, the secondary winding of spark coil 4 produces the negative high voltage pulse, diode D1 is on state, display tube 3 conducting under the high pressure effect, distributor 5 electronic work and drive contact switch K1 action, thereby make capacitor C 3 constantly charge and discharge.The counterelectromotive force that exist in the circuit this moment is isolated by diode D1 and display tube 3, stop distributor 5 counter electromotive force currents to get back to spark coil 4, and spark coil 4 reaches high pressure resonance accumulation of energy effect by C2, L3.When the inclined to one side end of the pulsed voltage of spark coil 4 output, C2 can play supplementary function, not only can reach the purpose of humidification in the high-voltage pulse of distributor 5, has improved ignition effectiveness, and can make pulse voltage amplitude keep constant.When distributor 5 low speed or high speed motion, the pulse voltage amplitude of powerful device 2 outputs becomes with it.Display tube 3 can play fault demonstration effect, promptly can differentiate the high-voltage pulse working condition by display tube 3.For example: display tube 3 no light beams, motor is inoperative, illustrates that circuit is obstructed.
The structure of the high voltage wire 1 among the above embodiment is seen Fig. 2, high voltage wire 1 by damping layer 11, nichrome core 12, rubber external insulation layer 13 totally three layers constitute; Wherein nichrome core 12 is wound on the damping layer 11, is equivalent to the circuit of inductance and resistance series connection.It can bear high-voltage pulse and passes through, and has the characteristics high temperature resistant, that insulating property are good.
