Abstract
The utility model relates to a capacitor discharging electric igniter, which is characterized in that a pulse transformer is used in place of a petrol engine ignition coil. In the first place, a direct current converter lifts the 12V direct current to a 500V impulse voltage which is then enlarged to ten of thousands volts as an ignition voltage by a high-voltage pulse generator and a triggering circuit, wherein, the direct current converter is coupled with the high-voltage pulse generator via a primary step-up pulse transformer; the high-voltage pulse generator is connected with the triggering circuit by the control electrode of the thyristor. The device can efficiently raise the ignition efficiency and make the mixed gas burning more sufficiently to reduce exhaust pollution and the carbon deposit of the engine cylinder.
Description
The utility model relates to a kind of internal combustion engine ignition mechanism, in particular for the ignition of petrol engine.
Traditional petrol engine firing mode is: by the variation that is switched on or switched off control ignition coil primary current of platinum contact in the distributor, go out high pressure about 20,000 volts at the secondary induction of spark coil, produce spark at the spark plug place, the mixed gas that enters in the cylinder is carried out discharge igniting.Because it's the working life that conference has a strong impact on platinum is past the spark coil primary current, therefore can't further improve the secondary ignition voltage of spark coil, ignition effectiveness is low like this, and mixture combustion is insufficient, and smoke density is big.At present, some R﹠D institution or automobile factory have developed the petrol engine ignition, and have dropped into practical application.It has just adopted electronic ignition mode, and former spark coil is not done any change, has therefore limited ignition voltage and has further improved, and promptly can not significantly improve ignition effectiveness.
The purpose of this utility model is that a kind of one capacitor discharge type ignition that boosts will be provided, and it can improve the petrol engine ignition effectiveness effectively.
The utility model is achieved in that DC converter that is controlled by pulse signal generator of clock of design, by a step-up pulse transformer 12V direct current is upgraded to the 500V pulsed voltage, and this voltage charges to storage capacitor after rectification.Storage capacitor is through controllable silicon and the elementary discharge of secondary booster pulse transformer, goes out tens thousand of volt high pressure as ignition voltage at the secondary induction of secondary booster pulse transformer.The silicon controlled working state is subjected to control from the fire signal and the trigger circuit of a end.
The utility model adopts pulse transformer gasoline replacing machine spark coil, through twice boosting inverter, at the tens thousand of volt ignition voltages of the secondary generation of this pulse transformer.Therefore, improved ignition effectiveness, it is more abundant that mixture combustion is got, and reduced exhaust pollution and engine air and lacked middle carbon deposit.
The concrete structure of model utility is provided by following examples and accompanying drawing thereof.
Fig. 1 is the electrical schematic diagram according to the one capacitor discharge type ignition that boosts that the utility model proposes.
Describe the details and the working condition of this ignition in detail below in conjunction with Fig. 1.
The utility model comprises a DC converter (1), high-voltage pulse generator (2) and trigger circuit (3).Wherein the pulse signal generator of clock be made up of IC (NE555), frequency adjustment potentiometer W and attached peripheral cell of DC converter (1) and VMOS FET switch circuit and a step-up pulse transformer B1 form; High-voltage pulse generator (2) is made up of rectifier lamp D7, controllable silicon T and secondary booster pulse transformer B2 etc.; Trigger circuit (3) are made up of unijunction transistor BG1, promotion pipe BG2 etc.During work, the VMOS FET switch circuit produces the 1:1 square wave under the control of pulse signal generator of clock, by a step-up pulse transformer B1 12V direct current is upgraded to the 500V pulsed voltage, this voltage charges to storage capacitor C7 after the rectifier lamp D7 rectification in knot high-voltage pulse generator (2).When the fire signal from a end arrives, trigger circuit (3) are started working, the trigger signal that it produced makes controllable silicon T conducting, storage capacitor C7 is through the elementary discharge of controllable silicon T and secondary booster pulse transformer B2, induces tens thousand of volt high pressure as ignition voltage secondary (being the b end) of secondary booster pulse transformer B2.
Claims (2)
1, a kind of body capacitance of boosting is put the formula ignition, it is characterized in that this igniter comprises the DC converter (1) that the 12V direct current can be upgraded to the 500V pulsed voltage, and the 500V pulsed voltage can be risen to pulse oscillator (2) and the trigger circuit (3) of tens thousand of volt high pressure into igniting usefulness, pass through a step-up pulse transformer B between DC converter (1) and the high-voltage pulse generator (2)
1Coupling; The control utmost point by controllable silicon T between high-voltage pulse generator (2) and the trigger circuit (3) is connected.
2, the one capacitor discharge type ignition that boosts according to claim 1 is characterized in that comprising in the DC converter (1) pulse signal generator of clock and a switching circuit that is subjected to this pulse signal generator of clock control output 1:1 square wave.
