Description

gasoline engine spark plug

technical field

The utility model relates to a gasoline engine spark plug.

Background technique

Chinese patent 200620066545.3 announced a "ring-shaped fine electrode spark plug". Its purpose is to provide a ring-shaped fine electrode spark plug. The firing end of the fine center electrode with a diameter of 1.2-1.8mm is welded with a 1-1.2mm thick precious metal sheet. The ring-shaped outer electrode is in the shape of a ring with a concave groove inside. , the surface area of the inner and outer electrodes is correspondingly reduced, thereby reducing the flame suppression effect of the electrodes, and the flame core grows rapidly, so that the lean mixture is fully burned, and the purpose of exhaust gas purification and fuel consumption reduction is achieved. The technical solution is that the ring-shaped fine-electrode spark plug is composed of a thin center electrode, a ring-shaped outer electrode, a sealing gasket, an iron shell, a conductive glass glue, an insulating ceramic body, a wiring screw, and a wiring nut. Low, long ignition duration, small electrode flame suppression effect, rapid growth of flame core, full combustion of lean mixture, increased power, reduced pollution, reduced fuel consumption, good heat dissipation, simple and durable manufacturing process. Its shortcoming is: fuel oil combustion rate is low, and combustion is not sufficient.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the above-mentioned prior art, to provide a tungsten spark ring installed on the spark machine of the gasoline engine, so that the inside of the engine emits high heat (1260 degrees), and when the piston retreats, its cylinder The fuel inside is heated, and the fuel in the gasified state inside is vaporized more finely, and it is easier to completely fuel 100% of the fuel when it explodes, reducing harmful exhaust mist and spark plugs for gasoline engines that reduce environmental pollution.

The purpose of this utility model can be achieved through the following measures:

The gasoline engine spark plug includes a ground electrode, a center electrode and ceramic plates, and its special feature is that a spark ring made of tungsten wire is arranged at the end of the spark plug.

The purpose of this utility model can also be achieved through the following measures:

The spark ring is composed of a spring-shaped annular member which is continuously encircled longitudinally; one end of which is fixed at the end of the spark plug.

The cross section of the spark ring is circular.

The cross section of the spark ring is elliptical.

The cross section of the spark ring is U-shaped.

The spark ring is composed of an annular member which is continuously and horizontally surrounded; its two ends are respectively fixed at the ends of the spark plug.

The longitudinal section of the spark ring is a ring in which U-shaped openings are arranged forward and backward in a staggered manner and continuously surrounds.

The bottom angles of the U-shape are vertical, that is, the bottom sides of the U-shape are parallel to the end cross-section of the spark plug, and the longitudinal sides of the U-shape are parallel to each other.

The longitudinal section of the spark ring is a parabolic staggered and continuous circular ring.

The longitudinal section of the spark ring is semi-circular or semi-elliptical in a staggered and continuous ring shape.

Compared with the prior art, the utility model has the following advantages:

1. The emission standard of gasoline engine gas has been improved.

2. The gas combustion of the gasoline engine is sufficient, and its emission is more in line with the requirements of environmental protection.

3. Improve the service life of the gasoline engine.
