Abstract
The utility model relates to a stacked multi-contact sparking plug. The utility model is relevant with the sparking plug of the engine ignition device. The utility model mainly solves the problems that the contact gap of the existing sparking plug has easy deformation, the ignition effect is poor, and the service life is short. The stacked multicontact provided by the utility model is divided into five stages, is fixed in a cylindrical ceramic body by the equal angle, and is respectively stacked in the space between the positive electrode and the negative electrode by the equidistance height step by step. When the positive electrode is connected with a power supply, as the contacts from the first stage to the fifth stage are uniformly arranged and are vertically stacked, the ignition time is long, the spark bundle is integrated, the strength is good, and the service life is good.
Description
The utility model is relevant with the spark plug in the engine ignitor.Specifically a kind of engine spark plug that improves the contactless ignition structure.
At present, the spark plug in the engine ignitor, its structure is made up of a positive pole and a negative pole of isolating ground connection with it.Thereby, have only a contactless ignition between positive pole and the negative pole, in the high-tension ignition process, make the contact gap distortion easily, cause the igniting weak effect, spark plug shortening in useful life.In light of this situation, people attempt to make it to be in same level height with positive pole by three contacts are set on spark plug negative pole circle, to solve the problem that the negative pole single contact exists.But owing to be provided with three contacts and negative pole is on a polar body, in fact can not solve the problem that a contactless ignition is deposited, easier on the contrary each contact gap that causes is inconsistent, the spark dispersion that produces when making igniting or the fiery phenomenon that daps.For above-mentioned reasons, cause the cylinder mixture combustion incomplete, the oil consumption height, exhaust emissions can not be up to standard.
The purpose of this utility model provides a kind of superposing type multiconductor spark plug, to solve the drawback that conventional ignition plug exists, the ignition performance and the useful life of improving spark plug makes the cylinder mixture combustion abundant simultaneously, reaches fuel savings.
Realize the technical solution of the utility model: this superposing type multiconductor spark plug, which comprises at least a center and be embedded with the negative pole that anodal cylindrical ceramic body and are attached to the outer and bonding of cylinder, described superposing type multiconductor divides Pyatyi, in the cylindrical ceramic body, and be superimposed on space between positive pole and the negative pole step by step successively by impartial fixed angle with the equidistant height of 1mm-1.5mm.Superposing type multiconductor spark plug, its negative pole and first order contact angle are 54 °, first order contact and contact, the second level, contact, the second level and third level contact, third level contact and fourth stage contact, angle between fourth stage contact and the level V contact is 54 °, and the angle between level V contact and the negative pole is 90 °.
The superposing type multiconductor spark plug that the utility model provides the experiment proved that, after positive pole is connected DC power supply; because first order contact to level V contact is evenly arranged; vertical stack is formed, and not disturbed by the cylinder gases at high pressure, guarantees the continual transmission step by step of spark; make the duration of ignition long; shower of sparks is concentrated, and intensity is good, impels the mist in the combustion chamber to obtain more fully burning; general energy fuel-economizing 3%-5%, and exhaust emissions is improved.Spark plug is improved useful life.
Further specify the utility model below in conjunction with accompanying drawing.Accompanying drawing 1 is a superposing type multiconductor spark plug cut-away view, and accompanying drawing 2 is superposing type multiconductor spark plug stack multiconductor floor plan schematic diagrames.
In accompanying drawing 1, positive pole 1, negative pole 2, third level contact 3, level V contact 4, screw thread 5, cylinder ceramic body 6, hexagonal metallic object 7, high pressure live wire plug 8.
In accompanying drawing 2, its centre dot is anodal, and the negative pole and the first order are to the flat state of level V stack contact angular divisions.
The utility model in force, its negative pole and the first order all adopt wide 2mm to the level V contact, the flat metal material of thick 1mm is superimposed on the contact between positive pole and the negative pole, embeds in the cylindrical ceramic agglomerated material, high temperature sintering is fixed.
Claims (2)
1, a kind of superposing type multiconductor spark plug that is applicable in the engine ignitor, which comprises at least a center is embedded with anodal cylindrical ceramic body and one to be attached to cylindrical ceramic external, and the negative pole of bonding, it is characterized in that superposing type multiconductor branch Pyatyi, press impartial fixed angle in the cylindrical ceramic body, and, be superimposed on the space between positive pole and the negative pole step by step successively with the equidistant height of 1mm-1.5mm.
2, superposing type multiconductor spark plug according to claim 1, it is characterized in that negative pole and first order contact angle are 54 °, first order contact and contact, the second level, angle between the second level and third level contact, third level contact and fourth stage contact, the fourth stage and the level V contact is 54 °, and the angle between level V contact and the negative pole is 90 °.
