Embodiment
By reference to the accompanying drawings, embodiments of the invention are provided as follows:
As shown in Figure 1: the automobile described in the present embodiment, motor cycle ignitor connect auxiliary ignition device at the high-voltage output end of existing automobile, motorcycle ignition mooring points fire coil DH, and this auxiliary ignition device forms primarily of high voltagehigh frequency diode D, spark plug J, high voltagehigh frequency capacitor C, electrical discharger F, high-frequency oscillating circuits G.High voltagehigh frequency diode D is connected on initial point fire system high-pressure cylinder line (for motor car engine, refer to high pressure cylinder separating line) connect in the circuit of spark plug, through spark plug gap, J forges iron (the two is series connection downlink connection), the object of access high voltagehigh frequency diode D prevents from electric discharge moment from this circuit, producing high-frequency sasser (after adopting this circuit, can using effect good copper core high voltage wire) to cause environmental pollution; Be connected in parallel in two telegraph circuits of spark plug J after high voltagehigh frequency capacitor C connects with electrical discharger F.I.e. high voltagehigh frequency capacitor C and the electrical discharger F accessing certain capacity in parallel in spark plug J bypass, high voltagehigh frequency capacitor C and electrical discharger F is connected in series, the object of access high voltagehigh frequency capacitor C makes discharging energy concentrate release, and ensureing that ignition point has additionally increases fault offset.The order of access electrical discharger F ensures that a point can keep the current potential comparatively born before each electric discharge.The output terminal of high frequency oscillation circuit (be element circuit, adopt known general 555 vibrator circuits) is connected on the circuit between high voltagehigh frequency capacitor and electrical discharger.Namely the positive pole of high-frequency oscillating circuits connects the positive pole of automobile power source, and its negative pole forges iron.High-frequency oscillating circuits G, in order to additionally to provide energy to high voltagehigh frequency capacitor C, ensures that each discharging time high voltagehigh frequency capacitor C can lay in the discharging energy leaned on.
Because firing circuit is in the moment of igniting, automobile, motorcycle ignition system must ensure that the centre electrode of spark plug is negative pole (being easy to electron emission), so, high-frequency oscillating circuits G must be negative value to the voltage that high voltagehigh frequency capacitor C provides, and be equal to or less than the voltage that electrical discharger F controls, the current direction of electric discharge moment is the b direction in figure, namely electric charge is from a negative plate of high voltagehigh frequency container C, " forged iron " by electrical discharger F, then through the negative pole " arcing " of spark plug to the centre electrode of spark plug, again through interlock circuit on the opposite side pole plate of high voltagehigh frequency electric capacity C, the automobile making the spark at J place, spark-discharge gap more usual, motorcycle ignition system strong more than 100 are doubly because high voltagehigh frequency capacitor C participates in electric discharge! this ensures that the present invention has the basic place of obvious energy-saving effect and good exhaust index.
The transient switching current potential of electrical discharger, should lower than the breakdown potential of spark plug gap (to prevent spark plug in the electric discharge of absence of discharge moment); The output terminal of high frequency oscillation circuit, must be negative value (negative potential, need with corresponding points firearm), and this current potential will be equal to or higher than the discharge voltage (in order to avoid electrical discharger forces electrical discharger should not discharge under discharge scenario because vibrator circuit output voltage is too high) of electrical discharger.But should be as far as possible close.
Experimentally, the withstand voltage of high voltagehigh frequency diode D is 2-3 ten thousand volts, and its deadline is 2-9 nanosecond; High voltagehigh frequency capacitor C is withstand voltage is 2-3 ten thousand volts, and its capacity is 180-250PF; Between the control voltage 3500-4500 volt of electrical discharger F; The output voltage of high-frequency oscillating circuits G is negative about 3500 volts.
