Description

High-energy igniter

The utility model relates to a kind of igniter that is used to strengthen gasoline engine ignition system electrical spark energy.

Traditional gasoline engine igniter, the electrical spark finite energy that is produced, it can not light the ratio inflammable mixture comparatively bigger than normal of air and gasoline, thereby makes it have the energy consumption height, the tail gas pollution important disadvantages.More incompatibility clean fuel automobile fuel burning-point is apparently higher than the characteristics of gasoline.Recently the transistor ignitor that adopts has improved the ignition ability of igniter greatly, but owing to there is following problem, make its in use difficulty on the light-duty visitor, lorry: 1. initial electrical signal is faint, must repeatedly amplify processing through complicated circuit, gets rid of difficulty in case break down; 2. adopt the element of poor heat resistance such as germanium tube, the high-temperature work environment of incompatibility lorry; 3. cost height.

The purpose of this utility model provides a kind of high-energy igniter.It can obviously improve petrolic ignition energy, improve the adaptedness of motor to inclined to one side weak mixture, the high-temperature work environment of light-duty visitor, lorry in being applicable to, cost is low, easy to use, reliable, and can fuel saving, reduce the pollution of vehicle exhaust, can also satisfy the requirement that clean fuel automobile must be strengthened spark energy.

For reaching above-mentioned purpose, of the present utility model being characterised in that with circuit breaker K ₄With throw over switch K ₃Input end connect capacitor C ₂Positive pole and negative pole and the throw over switch K of coil L ' ₃Second output terminal connect; Resistance R ₁With R ₂After the series connection, R ₁Be connected with power line; R ₂With triode T ₁Base stage connects, R ₁With R ₂Serial connection point and throw over switch K ₃First output terminal connect; Triode T ₁Grounded-emitter connection, collector electrode and resistance R ₃Connect resistance R ₃Be connected with power supply; Triode T ₂Base stage and triode T ₁Collector electrode connect triode T ₂Grounded-emitter connection, collector electrode is connected with the negative pole of spark coil L, the positive pole of spark coil L and resistance R ₄Connect resistance R ₄Be connected with power supply; Starter motor on-load switch K ₁Be connected with the positive pole of spark coil L; Capacitor C ₁Respectively with triode T ₂Collector electrode, emitter connect.

The utility model is owing to use switch triode Control work electric current, increased the variance ratio of interruption current, spark energy is strengthened greatly, can improve the working condition of the inclined to one side weak mixture of motor significantly, the performances such as starting, low speed, acceleration of motor are improved, therefore be specially adapted to clean fuel automobile; Use the utility model the oily plane of back Carburetor can be turned down, inflammable mixture concentration is descended, obviously the pollution of fuel saving and reduction vehicle exhaust.The utility model can change two ignition mechanisms owing to also kept original ignition mechanism simultaneously easily, has improved the reliability of using.

Below in conjunction with accompanying drawing the utility model is described further.

Fig. 1 is a circuit diagram of the present utility model.

With circuit breaker K ₄With throw over switch K ₃Input end connect capacitor C ₂Positive pole and negative pole and the throw over switch K of coil L ' ₃Second output terminal connect; Resistance R ₁With R ₂After the series connection, R ₁Be connected with power line; R ₂With triode T ₁Base stage connects, R ₁With R ₂Serial connection point and throw over switch K ₃First output terminal connect; Triode T ₁Grounded-emitter connection, collector electrode and resistance R ₃Connect resistance R ₃Be connected with power supply; Triode T ₂Base stage and triode T ₁Collector electrode connect triode T ₂Grounded-emitter connection, collector electrode is connected with the negative pole of spark coil L, the positive pole of spark coil L and resistance R ₄Connect resistance R ₄Be connected with power supply; Starter motor on-load switch K ₁Be connected with the positive pole of spark coil L; Capacitor C ₁Respectively with triode T ₂Collector electrode, emitter connect.

As contact breaker points K ₄When closed, the power on signal electric current I ₁By K switch ₂Through resistance R ₁, throw over switch K ₃, contact breaker points K ₄Flow to ground connection, at this moment triode T ₁Base potential be 0, triode T ₁End; Promote electric current I ₂Through K switch ₂, resistance R ₃, triode T ₂Base stage, emitter flow to ground connection; Triode T ₂Conducting; Operating current I ₃Through K switch ₂, resistance R ₄, spark coil L positive and negative electrode, triode T ₂Collector electrode, emitter flow to ground connection, at this moment, have electric current to pass through among the spark coil L.

As contact breaker points K ₄During disconnection, signal code I ₁' by K switch ₂Through resistance R ₁, R ₂And triode T ₁Base stage, emitter flow to ground connection, this moment triode T ₁Conducting.Promote electric current I ₂' by K switch ₂Through resistance R ₃, triode T ₂Collector electrode, emitter flow to ground connection, triode T ₂End, no current passes through among the spark coil L.At operating current I ₃Moment from having to do not having, the elementary generation self induction electromotive force of spark coil L also produces high voltage induced current in the level secondarily, and this electric current is directed to and produces the high energy electrical spark on the spark plug.The leading peak part of the self inductance current of the elementary generation of spark coil L is through capacitor C ₁Flow to ground connection,, protected triode T with the spike part of the elementary self induction electromotive force that is produced of the spark coil L that prunes ₂Capacitor C ₂The electric weight that stores is at triode T next time ₂During conducting, by triode T ₂Collector electrode, emitter discharge, and are capacitor C ₂To work ready next time.

When the generator starting working state, starter motor negative charge K switch ₁Closure, operating current I ₃By K switch ₁Directly flow to the positive and negative electrode of spark coil L, then through triode T ₂Collector electrode, emitter flow to ground connection.

As contact breaker points K ₄When closed again, igniter repeats above-mentioned work, can make ignition mechanism continuous operation constantly.

When this igniter breaks down, with throw over switch K ₃Be transformed into former ignition system working state, this moment, spark coil L quit work, and former spark coil L ' starts working, to guarantee the proper functioning of whole ignition mechanism.

The utility model igniter also is specially adapted to the needs of clean fuel motor to lifting power and starting cold, and is applicable to ignition device of gasoline engine except that the changeable working condition that is applicable to motor car engine.
