Problems solved by technology

From the research on ethanol fuel engines, the existing spark plug metal electrodes have a general heat conduction effect and are prone to ablation when ethanol is burned. The reason for the ablation lies in the poor thermal conductivity of the electrode itself.

Embodiment Construction

[0027] The technical solution of the present invention will be described in detail below through specific examples. It should be understood that the following examples are exemplary only, and can only be used to explain and illustrate the technical solution of the present invention, and cannot be construed as an explanation of the technical solution of the present invention. Program limitations.

[0028] Such as Figure 2 to Figure 3 As shown, the ethanol-gasoline flexible fuel engine spark plug includes: a metal shell 1 , a center electrode 2 , a side electrode 3 , an insulator 4 , and a spark plug body 5 .

[0029] The metal shell 1 is located at the front end of the spark plug body 5, and the outer diameter of the metal shell 1 can be changed to 10mm or 14mm according to the needs of the engine. The center electrode is located in the metal shell, and the material of the center electrode is not within the protection scope of this application, because any material that can b...

Abstract

The invention provides a sparking plug of an ethyl alcohol-gasoline flexibly proportioned fuel engine. A metal casing is positioned at the front end of a sparking plug body, a central electrode is located in the metal casing, an insulator is located between the central electrode and the metal casing, a side electrode is welded on one side of a front port of the metal casing, precious metal electrodes are welded on one side of the side electrode and at the top of the central electrode, and the side of the side electrode is near the central electrode. The horizontal width of the side electrode is longer than the vertical length of the side electrode, so that heat in an engine cylinder can be well transmitted, and the side electrode itself can be protected from being ablated by high temperatures; the side electrode is shorter than ordinary engine sparking plugs, and heat conduction effects of the side electrode are better; and the precious metal electrodes are located on the side electrode and the central electrode respectively, the size and the width of the precious metal electrodes are the same, and heat lost during ignition of the sparking plug is reduced.

Description

technical field [0001] The patent of the invention relates to the technical field of the ignition system of an automobile engine, in particular to a spark plug for an ethanol-gasoline flexible ratio engine. Background technique [0002] Spark plugs are widely used in automobile engines. The function of spark plugs is to discharge the pulsed high-voltage electric energy transmitted by the ignition coil, break down the air between the two electrodes of the spark plug, and generate electric sparks to ignite the mixed gas in the engine cylinder and push the piston. Work is done to keep the engine running. The side electrode of the spark plug is generally a strip material, which is welded to the port of the spark plug shell by professional welding equipment, and the metal side electrode is bent to the vertical position of the center electrode to form an ignition gap with the center electrode. [0003] Chinese patent application number 200580007335 discloses a spark plug structur...
