Abstract
The utility model relates to an auxiliary device for automobile ignition. A circuit is composed of a PNP transistor and an NPN transistor. The circuit is connected to a platinum ignition circuit of the original automobile, a high-voltage ignition pulse can be broadened, and the ignition time can be extended. Because of the generation of secondary and third-time high-voltage sparks of the device, the ignition effect is improved, the device is quickly started especially under low-temperature starting conditions, and the starting power is large. Because fuel oil can be sufficiently burnt, the purposes of saving the fuel oil and reducing discharge amounts of waste gas can be achieved.
Description
The utility model relates to a kind of automotive ignition auxiliary device, specifically is to utilize electronic circuit to be connected on the existing automobile platinum ignition circuit to make it produce the automotive ignition auxiliary device of a plurality of high tension ignition pulses.
Existing platinum automotive ignition circuit, be by storage battery, ignition switch, the loop that spark coil and platinum contact are connected in series, the platinum contact is driven with the control loop on off operating mode by main shaft, thereby in the loop, produce backlash current, when in the loop electric current being arranged, be equivalent to store magnetic energy by the elementary electric current of spark coil to spark coil, when the loop disconnects, the instantaneous vanishing of electric current, so elementary the going up of spark coil produces induced voltage, on the boosting spark plug that the level winding connects secondarily of spark coil, produce high tension ignition pulse (being equivalent to discharge storing energy) to light fuel oil.It is generally acknowledged, the spark coil primary current changes more greatly, the voltage that secondary windings produces is high more, spark is strong more, the igniting situation is better, so traditional automotive ignition auxiliary device is to adopt the method that strengthens electric current [strength on the spark coil, though this method can improve the ignition voltage on the spark plug, but because the current transients time is short, its high tension ignition pulse endurance is corresponding also short, facts have proved that the igniting effect is unsatisfactory, especially when the low temperature ignition start, starting difficulty during as-10 ℃ of following temperature, oil inflame is insufficient because ignition duration is short, also causes fuel oil waste and the many defectives of pollution from exhaust emission amount.
The utility model aims to provide a kind of automotive ignition auxiliary device that can make the high tension ignition pulse that produces the relative prolongation of a plurality of endurance on the spark coil.
The utility model is realized as follows, the emitter of one PNP transistor is connected on the output point of ignition switch, this pipe base stage links to each other through the positive terminal of a resistance with the elementary winding of spark coil, its collector electrode forward connects diode and a resistance is connected on the base stage of a NPN transistor through one, the grounded-emitter connection of this NPN transistor, collector electrode are connected on the negative pole end of platinum contact and the elementary winding of spark coil.This model utility is connected the endurance prolongation that can make high tension ignition pulse with former automotive ignition circuit, promptly the high tension ignition pulse width increases, thereby has improved the igniting effect greatly.
Below in conjunction with drawings and Examples the utility model is described.
Fig. 1 is embodiment's circuit diagram of the present utility model, wherein:
1-automobile storage battery 2-ignition switch 3-additional resistance
4-spark coil 5-platinum contact 6-PNP transistor npn npn
7-resistance 8-resistance 9-diode
10-resistance 11-resistance 12-NPN transistor npn npn
13-damper diode 14-capacitance 15-filter capacitor
When engine start, main shaft drives platinum contact 5 on off operating modes with the control ignition circuit, when 5 closures of platinum contact, electric current flows through the elementary of spark coil 4 by the positive pole of storage battery 1 through ignition switch 2 and additional resistance 3, this just is equivalent to magnetize to store magnetic energy to spark coil 4, voltage on the resistance 3 provides forward bias for transistor 6 by resistance 7 and resistance 8 simultaneously, make transistor 6 conductings, the collector current of transistor 6 is through forward connecting diode 9 and resistance 10 inflow transistors 12 to ground, thereby forms current loop.When platinum contact 5 disconnects, transistor 6 is kept certain on state, and transistor 12 provides the afterflow path, makes electric current that spark coil 4 flows through on elementary can not suddenly change (comparatively speaking), this broadens with regard to the high tension ignition pulse that 4 levels of spark coil are produced, and can prolong firing time.In addition because the existence of line distribution capacitance, make the elementary winding of distributed capacity and spark coil 4 constitute the free-oscillation loop, this oscillating circuit can make spark coil 4 secondary windings produce high tension spark once more, forms two, three times electrical spark, further to light fuel oil, make oil inflame more abundant.
The utility model makes high tension ignition pulse broaden, be to prolong firing time, because the generation of secondary, three sub-high pressure sparks has improved the igniting effect widely, especially under low temperature condition, fast as starting below-10 ℃, starting power is big, because fuel oil energy fully burns, can reach the purpose of saving fuel oil and reducing discharge amount of exhaust gas, facts have proved that fuel-economizing can reach 15%, discharge amount of exhaust gas can reduce 50%.
