Problems solved by technology

[0002] The spark plug is a part of the gasoline engine ignition system that introduces high-voltage current into the cylinder to generate electric sparks to ignite the combustible gas mixture. At present, the common traditional automobile spark plug is composed of a metal shell, a ceramic insulator, a center electrode and a metal shell. Through the high-voltage ignition coil, the center The high-voltage discharge between the electrodes and the side electrodes generates sparks, which ignite the mixed gas fuel in the combustion chamber of the engine. The combustion of the mixed fuel pushes the piston to reciprocate, so that the crankshaft drives the engine to rotate. Generally, the spark plug only has one center electrode and

Abstract

The invention discloses a multi-electrode spark plug, comprising a metal shell, one end of the metal shell is provided with a ceramic insulator penetrating through the metal shell, a working side electrode and a guard electrode are provided, and the ceramic insulator passes through the metal shell One end of the ceramic insulator is provided with a wire nut, and the other end is provided with a center electrode and a suspension electrode. The center electrode and the wire nut are connected inside the ceramic insulator, and the ceramic insulator is provided with a suspension electrode. The suspension electrode is located between the center electrode and the side electrodes, and the metal shell, the center electrode and the side electrodes are not in contact with the suspension electrodes. The multi-electrode spark plug of the present invention can realize two ignitions, prolong the ignition time, make the fuel burn more fully, improve the efficiency of the engine, reduce harmful tail gas emissions, and reduce fuel consumption.

Description

technical field [0001] The invention relates to the technical field of spark plugs, in particular to a multi-electrode spark plug. Background technique [0002] The spark plug is a part of the gasoline engine ignition system that introduces high-voltage current into the cylinder to generate electric sparks to ignite the combustible gas mixture. At present, the common traditional automobile spark plug is composed of a metal shell, a ceramic insulator, a center electrode and a metal shell. Through the high-voltage ignition coil, the center The high-voltage discharge between the electrodes and the side electrodes generates sparks, which ignite the mixed gas fuel in the combustion chamber of the engine. The combustion of the mixed fuel pushes the piston to reciprocate, so that the crankshaft drives the engine to rotate. Generally, the spark plug only has one center electrode and one side electrode. It is easy to be damaged after use. In order to prolong the service life of the s...
