Description

one

The invention relates to a technique for igniting air-fuel mixtures, in particular spark spark plugs, and can be used in pulsating combustion devices and heating installations.

The aim of the invention is to increase the ignition efficiency of the combustible mixture by increasing the current value of the candle, as well as eliminate the leakage of the combustion chamber.

The fta drawing is a schematic representation of the proposed firing candle for tear-off.

The candle includes a housing 1, in which the side electrode 3 is fixed in the insulator 2, and the tubular housing 4, made of non-ferrous metal. Inside the tubular body 4 there is a movable central electrode 5, insulated from the body 1 and a spring 6, pressing the central electrode 5 towards the side electrode 3 to create an electrical contact between electrodes 3 and 5. On the top of the isolator 2. The winding 8 of the electromagnet 9 is placed, the measles 10 of which are made in one piece with the central electrode 5. The winding 8 has two terminals 11 and 12, with terminal 11 connected to side electrode 3 through winding 8, and through the spring 6 is connected to the movable central electrode 5. The tubular body 4 is plugged at one end to ensure the tightness of the combustion chamber.

The pilot candle works as follows.

When voltage is applied to terminals 11 and 12 under the action of an electromagnetic field, the moving electrode 5 tends to occupy a neutral position

relative to the winding 8 of the electromagnet 9, since the circuit through terminal 12, spring 6, electrode 5, side electrode 3, winding 8 and terminal 11 is in the short-closed position. The opening of the electrodes 3 and 5 under the action of an electromagnetic field is accompanied by a powerful spark discharge and the supply of voltage to the winding 8 stops; The winding is demagnetized, and the spring 6 returns the electrode 5 to its original position, i.e. until in contact with the electrode 3.

The process then repeats cyclically.

The spark ignition spark plug has a high ignition efficiency of the combustible mixture, especially heavy vomit, due to the formation of a spark with a high ignition energy, due to the supply of increased voltage to the candle electrodes.
