Description

Energy-gathering ring spark plug

Technical Field

The utility model relates to an energy-gathering annular spark plug.

Background technique

Spark plugs are important components of gasoline engine ignition systems. They can introduce high voltage electricity into the combustion chamber and break through the air between the two electrodes of the spark plug to generate sparks and ignite the combustible mixture in the cylinder. The spark plug is mainly composed of a wiring nut, an insulator, a center electrode, a side electrode and a shell. The side electrode is arranged at one end of the shell. The center electrode and the side electrode are arranged opposite to each other, and precious metal electrode needles are welded on the opposite sides of the two. The electric sparks generated by this type of spark plug under the action of high voltage electricity are generated between the tips of the two precious metal electrode needles, which belongs to point-to-point transmission. It has the following problems: 1. The number of electric sparks generated is limited, and the ignition efficiency is not high; 2. When carbon is deposited on the top of the electrode needle, it is easy to fail to ignite, and the service life is short.

Utility Model Content

In view of the defects of the existing energy-gathering ring spark plug, the technical problem to be solved by the utility model is to provide an energy-gathering ring spark plug with high ignition efficiency and long service life.

In order to achieve the above-mentioned purpose, according to one aspect of the utility model, the utility model is realized through the following technical measures: a kind of energy-focusing ring spark plug, comprising: a wiring nut, an insulator, a center electrode, a side electrode and a shell, one end of the shell is provided with a side electrode, the other end of the shell is provided with a wiring nut, an insulator is provided outside the shell, the center electrode and the side electrode are arranged opposite to each other, an electrode needle is fixed on the center electrode, an energy-focusing ring is fixed on the side electrode, a plurality of sharp-angled surface bosses are distributed on the top surface of the energy-focusing ring, the sharp-angled surface bosses contain sharp corners and edges, and the edges and sharp corners of the sharp-angled surface bosses form multiple power-connecting tips of the energy-focusing ring.

Furthermore, the electrode needles and the energy focusing ring are made of precious metals such as platinum, iridium, rhenium, and ruthenium.

Furthermore, the electrode needle is welded to the central electrode, and the energy focusing ring is welded to the side electrode.

Furthermore, the front angle surface bosses are evenly distributed on the energy focusing ring, and arc grooves are provided between adjacent front angle surface bosses.

Furthermore, the energy focusing ring is in the shape of a circular ring or a polygonal ring.

Furthermore, the front angle surface boss is a fan-shaped front angle surface boss or a polygonal front angle surface boss.

Compared with the prior art, the advantages of the utility model are: an energy-gathering ring is used to replace the electrode needle on the existing side electrode, and the discharge characteristics of the spark plug are improved in a ring-shaped ignition manner, and the rated voltage required to break through the air between the center electrode and the side electrode is reduced, while also making the ignition points more dense, enhancing the ignition intensity, and making the combustible mixture in the gas cylinder burn more fully, achieving the effect of energy saving and fuel saving and reducing emissions. The electrode needle of the center electrode and the power-connecting tips of each front angle boss form a multi-point ignition mode, and the tip effect is more significant, which solves the problem of spark plug failure caused by carbon deposition in some positions and increases the service life of the spark plug.
