Embodiment Construction

[0012] figure 1 , figure 2 Shown is a spark plug for a power generation internal combustion engine, including a center electrode 1 installed in a metal shell 14 and insulated from the metal shell 14. The metal shell 14 is electrically connected to the side electrode 2, and there is a spark between the center electrode 1 and the side electrode 2 gap. The side electrode 2 is in the shape of a ring, and a support frame 3 is provided between the side electrode 2 and the top of the metal shell 14, so that the side electrode 2 is separated from the top of the metal shell 14. The support frame 3 is composed of three sheet metal bodies, Evenly distributed between the outer edge of the side electrode 2 and the outer edge of the top end of the metal case 14 . The metal shell 14 is an iron pipe, the lower end of the center electrode 1 is embedded in the insulating magnetic piece 7 placed on the top of the metal shell 14, and the upper part of the insulating magnetic piece 7 is sealed...

Abstract

The invention is concerned with the improved surface discharge sparkplug electrode structure, includes: the central electrode in the metal shell but insulated with it by the insulator, the metal shell connects the side electrode by electricity, which appears in cirque and with the supporting shelf in between of the two, the end of the central electrode reaches out the center of the cirque electrode by passing through the skirt of the insulator over the top of the metal shell. The supporting shelf consists of the three lattice framing metal pieces allocate evenly in between of the side electrode outer margin and the metal shell top outer margin; the inner concave cirque groove is on the inner wall of the side electrode, where on their opposite location are several grooves on the pole surface of the central electrode with equidistant. The invention suits the electricity generated internal-combustion engine and the car spark plug of all sorts.

Description

technical field [0001] The invention relates to a spark plug. [0002] Background technique [0003] The side electrode and the center electrode of the ordinary surface discharge spark plug are concentric, forming a multi-directional annular electrode. Using the surface discharge spark plug can avoid the phenomenon of "cross-connection" and "bridge" that are easy to occur in the ordinary surface discharge spark plug. , but also to avoid the danger of early ignition. However, ordinary surface discharge spark plugs have almost no skirt, and the heat chamber is also very small. It is the coldest type of spark plug, which can only be used on two-stroke engines, and the effect is very poor when used on engines with more than four strokes, and the performance is obviously lost. Meet the needs of various types of engines. The main problems are: (1) The flashing position of ordinary surface discharge spark plugs is indented, and the spark accessibility is very poor; (2) The electr...
