Abstract

The utility model discloses a high-energy igniter, which belongs to the field of gasoline engine igniter. An igniter is connected to the original igniter device. The utility model can increase the ignition energy of gasoline engines evidently, and improve the adaptation degree of the engine to lean mixture, and is suitable to the hot operation environment of lorries and the requirement of clean fuel automobiles. The cost is low, the fuel is saved, and the pollution of the automobile exhaust is reduced. The utility model remains the original igniter device, and the working reliability is increased.

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.
