Description

A new spark plug for automobile

technical field

The invention relates to the technical field of automobile engineering, in particular to a novel spark plug for automobiles.

Background technique

The function of the spark plug is to introduce the high-voltage electricity (more than 10,000 volts) generated by the ignition coil into the engine cylinder, and generate an electric spark between the electrodes of the spark plug to ignite the combustion of the mixture. A traditional car consists of a metal shell, a ceramic insulator, a center electrode and a metal shell. The high-voltage discharge between the center electrode and the side electrode generates sparks through a high-voltage ignition coil, ignites the mixed gas fuel in the engine combustion chamber, and the mixed fuel burns to push the piston. Reciprocating motion, so that the crankshaft drives the engine to rotate. Generally, the spark plug has only one center electrode and one side electrode, which is easy to be damaged after long-term use.

Contents of the invention

The technical problem to be solved by the present invention is to provide a new type of spark plug for vehicles, the spark plug is provided with a center hole in the center electrode to fully burn gasoline, reduce fuel consumption, increase power, and reduce environmental pollution, and The spark plug is equipped with a protective electrode and a sharp discharge point, which can improve the service life of the spark plug; and the central electrode of the fire piston is made of corrosion-resistant and oxidation-resistant nickel-cadmium alloy metal material, which further improves the service life of the spark plug.

The present invention is achieved like this:

A new type of spark plug for vehicles, including a spark plug body, a central electrode is set at the center line of the spark plug body and the center electrode is wrapped by the spark plug body, a discharge sharp corner is set on the top of the center electrode and the discharge sharp corner exposes the spark plug body, and the top of the spark plug body A side electrode is arranged on one side, and a suspension electrode is arranged on the side electrode and the discharge tip, and the suspension electrode is arranged on the top of the spark plug body. The side electrode, the suspension electrode and the discharge tip are independent of each other, and a through-hole The central hole, the upper end of the central hole corresponds to the position of the sharp corner of the discharge.

In the aforementioned new type of spark plug for vehicles, the tops of the side electrodes, the suspension electrodes and the discharge peaks are kept on the same horizontal plane, and by setting the suspension electrodes, the side electrodes and the discharge peaks respectively form arcs with the suspension electrodes, which can realize Two ignitions, and the above-mentioned heights are consistent, so that the formation of arcs does not affect each other, and will not cause damage to the other electrode caused by the arc.

In the aforementioned new type of spark plug for vehicles, a protective electrode is provided on the other side of the top of the spark plug body, and the side electrode, floating electrode, discharge sharp corner and protective electrode are located on the same vertical plane, and the protective electrode does not participate in the ignition process by setting the protective electrode. That is, no arc is generated on the central electrode or the floating electrode, and the protective electrode can prevent the central electrode and the floating electrode from contacting the spark plug hole, prevent the central electrode and the floating electrode from being damaged due to collision, and is beneficial to prolong the service life.

In the aforementioned new spark plug for vehicles, the top of the protective electrode is higher than the top of the sharp discharge point.

Due to the adoption of the above technical scheme, compared with the prior art, the central electrode material of the present invention has high corrosion resistance and high temperature resistance, which improves the service life of the spark plug; the central electrode side is provided with a central hole, which can make gasoline fully burnt and is beneficial Protect the environment; the top of the center electrode is equipped with a discharge sharp angle to overcome the difficulty of ignition and thus improve the service life of the spark plug.
