Abstract
The utility model relates to a petrol engine electronic igniter which belongs to an igniting device for an internal combustion engine. The utility model is characterized in that the negative pole of a power source is grounded, and the positive pole is connected with an ignition switch; a control circuit which is composed of a resistor, a transistor and a diode is arranged in an ignition circuit. The utility model has the advantages of simple structure and reliable work. Low current controls heavy current in a circuit structure, and the current which passes through the contact of a breaker is decreased into number ten milliamperes so that the utility model is not ablated by sparks any longer and the service life of the utility model is extended. The diode in the control circuit can eliminate reverse voltage which is generated by the primary winding of an ignition coil so as to effectively protect the transistor and the ignition coil. The utility model is widely used as the electronic igniter of various petrol engines.
Description
The petrol engine ignition belongs to a kind of ignition device for internal combustion.
At present petrol engine is employed a contact transistor ignition, is generally plus earth, and the ratio of its spark coil secondary windings and elementary umber of turn is big, and the circuit complexity, and transistor damages easily.CN2140969Y discloses a kind of ignition, form by transistor circuit, it is characterized in that the primary ignition electric current does not pass through the platinum contact of distributor, though avoided the sintering of big electric current to the contact, but initial firing current is still bigger to transistorized impact, and is fragile.
The purpose of this utility model is to provide a kind of simple in structure, the petrol engine ignition of reliable operation.
The utility model is to realize above-mentioned purpose like this.The minus earth of power supply, positive pole is connected with ignition switch.In the firing circuit by the control circuit of forming by resistance, triode and diode, its circuit connecting relation is: resistance is connected between ignition switch and the elementary winding of spark coil, be parallel with diode between the collector and emitter of triode, emitter is connected with the series connection end of spark coil; Between collector electrode is with resistance and the elementary winding of spark coil, be in series with diode, and draw ground wire in the line by two diodes; Base stage is by ground connection after the pair of contact of circuit breaker.
The utlity model has simple in structure, the characteristics of reliable operation.On the circuit structure with the big electric current of little Current Control; can quicken flux change; improve the secondary voltage of spark coil; and will be reduced to tens of milliamperes by the electric current of contact breaker points; it is no longer ablated by spark; increase the service life: and the diode in the control circuit can eliminate the backward voltage that the elementary winding of spark coil is produced, and protects triode and spark coil effectively.Be widely used in various petrol engine and make ignition, replace use at present contact ignition and traditional battery ignition device arranged.
Accompanying drawing is circuit theory diagrams of the present utility model.
