Abstract

The utility model relates to a spark plug for the ignition of a petrol engine, which is the improvement for the utility model patent with the patent number of 86208357. The utility model adopts an annular lateral electrode having a plurality of projecting angles, and the internal diameter of the annular lateral electrode is larger than the external diameter of a circular column of an insulating body which is matched with the annular lateral electrode. The utility model mainly solves the problem that the ignition reliability is lost because a plurality of conducting rings are connected into an integrative structure when the spark plug is used for a long time to be result in the slag collection. Simultaneously, the utility model improves the oil saving effect further. The utility model can be widely used for the ignition devices of the petrol engines of cars and other vehicles of various types.

Description

Oil-saving spark plug

The utility model relates to a kind of gasoline engine ignition spark plug.

In No. 86208357 patents of declaring in 1986, proposed to use many ring relay-types to get angry at random in person to produce the structural design of continuously sparking quickening burning rate, really played the reduction heat energy loss in actual applications, save the purpose of oil plant, make and be installed in a conducting ring on the insulator and connect electricity but in long-term the use, occur accumulated slag sometimes, causing that igniting loses reliability problems.

For addressing the above problem, it is strong that the purpose of this utility model provides a kind of spark, the long-time reliable novel fuel-saving sparking plug of also further saving oil plant of igniting that uses.

For achieving the above object, the utility model has been taked following design: it comprises a kind of fuel-saving sparking plug: wiring nut, insulator, wiring screw rod, iron-clad, electro-conductive glass, central electrode, conducting ring, electric conduction electrode-plate, it is characterized in that: it also comprises the lateral electrode that has a plurality of outstanding angles of an annular, the annular internal diameter of described lateral electrode is greater than the cylinder external diameter of the described insulator that is mated, have a recessed edge in the bottom of described iron-clad, described lateral electrode is mounted and fixed in the described recessed edge.

The utility model is owing to adopt an annular to have the lateral electrode at a plurality of outstanding angles, and itself and insulator kept certain distance, be installed on the iron-clad, make and be difficult for producing accumulated slag between itself and the next conducting ring, cause and connect electrical short, guaranteeing that long-term use igniting guarantees to light rarer gaseous mixture in reliable and stable, it is fully burnt, promptly save oil plant and reduced the pollution of vehicle exhaust again environment.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.

Accompanying drawing 1 is a structural representation of the present utility model

As shown in Figure 1: wiring nut 1 and wiring screw rod 3 are used thread connection, filled conductive glass 5 between wiring screw rod 3 and the central electrode 6, and this electro-conductive glass 5 is bonded in the insulator 2 with wiring screw rod 3 at the following central electrode 6 of molten condition, and can make the two conducting.Keep the following several conducting rings 10 in the patent design No. 86208357, change a top conducting ring into lateral electrode 13 that an annular has four outstanding angles, have recessed edge 9 in iron-clad 4 bottoms, lateral electrode 13 is installed and welded extremely in recessed edge 9, the size of the annular internal diameter 8 of lateral electrode 13 is greater than the cylinder external diameter 7 of the insulator 2 that is mated, make lateral electrode 13 and insulator 2 keep certain distance, when long-time use accumulated slag increases, do not cause lateral electrode 13 and following conducting loop-shaped to be integral, solved the igniting integrity problem effectively, outstanding angle 12 on the lateral electrode 13 forms stronger pilot spark with next conducting ring 10 and can light rarer gaseous mixture simultaneously, further saved oil plant, and reduced the pollution of vehicle exhaust environment.The utility model has still kept the design of a plurality of conducting rings 10 and electric conduction electrode-plate in original design in addition, has made it to keep the advantage of the continuously sparking of many rings relay-type.

In the foregoing description, the outstanding angle 12 on the annular lateral electrode 13 also can be three or more.

Claims

1, a kind of fuel-saving sparking plug, it comprises: wiring nut 1, insulator 2, wiring screw rod 3, iron-clad 4, electro-conductive glass 5, central electrode 6, conducting ring 10, electric conduction electrode-plate 11, it is characterized in that: it also comprises the lateral electrode 13 at having of an annular of a plurality of outstanding angles 12, the annular internal diameter 8 of described lateral electrode 13 has a recessed edge 9 greater than the cylinder external diameter 7 of the described insulator 2 that is mated in the bottom of described iron-clad 4, and described lateral electrode 13 is mounted and fixed in the described recessed edge 9.
