Abstract
Disclosed is a high strength heat-resisting energy efficiency circulating spark plug. An electrode is a slight exposure electrode internally placed in a silicon carbide outer coating layer. A heat conduction unit is arranged in the range of electrode heat effect influence inside an air cylinder so that high temperature energy can be led to an air conditioner circulating system inside an automobile and energy efficiency support is offered to air conditioner system circulation. A lower end face of the shell body is welded with a grounding electrode. A gap of 0.6mm-1.0mm is formed between a central electrode and the grounding electrode. Sparks are generated in a bursting mode to light mixed gas when high voltage electricity passes through the gap to the ground. Corrosion resistance and oxidation resistance of a nickel-cadmium metal material is 8-10 times as much as those of a traditional spark plug. The high strength heat-resisting energy efficiency circulating spark plug is assembled in a fuel oil air cylinder of a common compact type automobile and service life reaches up to 3-5 years. The high strength heat-resisting energy efficiency circulating spark plug is suitable for automobile types of the Subaru, the Volvo, the Peugeot 307, the Peugeot 206, the Dongfeng Citroen, the Grandis, the Galant, the Savrin, the Fuga, the Yumsun MVP, the Teana, the new Teana, the Vios, the imported Prado, the Reiz, the Prado 4.0 L and the like.
Description
Technical field
The present invention relates to a kind of spark plug, especially a kind of high resistance spark plug.
Background technology
The effect of spark plug is that the high-tension electricity (more than 10,000 volts) that ignition coil produces is introduced cylinder, produces the spark ignition gaseous mixture between the gap of sparking-plug electrode.The operational environment of spark plug is very abominable, and take the spark plug of the logical four-stroke gasoline engine of a Daepori as example, temperature only has 60 ℃ when induction stroke, pressure 90KPa; And when ignition, temperature can rise to 3000 ℃ moment, and pressure reaches 4000KPa; The alternating frequency of this rapid heat cycle is very high, is not that general material can be dealt with, and also will guarantee insulation property, and is therefore also just very harsh to the material requirements of spark plug.
The spark plug key component is insulator, if insulator is inoperative, high-tension electricity will " cut corner " and enter ground without the two poles of the earth, causes the no-spark phenomenon.The insulator of spark plug must have good mechanical performance and high voltage withstanding, high temperature resistant impact, the ability of resistance to chemical attack, and adopt take aluminium oxide as the pottery on basis of common spark plug made more.The size of spark plug is that the whole world is unified, can be general on any automobile, but because the petrol engine type is had any different, so spark plug also can divide two kinds of fundamental types, cold mould and patterns of fever are arranged.Cold mould and pattern of fever are comparatively speaking, and it has reflected the thermal characteristics performance of spark plug.Spark plug will have suitable temperature could work well, does not have carbon deposit ability working properly.Facts have proved when spark plug insulator remains on 500-600 ℃ of temperature, drop on insulator oil droplet immediately burning-off can not form carbon deposit, can pre-ignition higher than this temperature, lower than this temperature, carbon deposit is arranged.Temperature on different engines can be different, and the designer solves this contradiction with regard to the length of utilizing insulator tip.The short heating surface area in some skirt section is little, rapid heat dissipation, so the skirt section temperature is low, is called soft plug, is applicable to the high-power engine of high speed and high pressure contracting ratio; The elongated heating surface area in some skirt section is large, and heat radiation is slow, so the skirt section temperature is high, is called hot (spark)plug.
