Abstract
The utility model relates to a solid core spark plug which adds insulating ceramic into the gap of the existing spark plug. The ceramic at the ignition point of an electric pole forms a circle-arc surface. The utility model overcomes the defect that the carbon deposit of the spark plug is difficult to remove, and provides a short cut for repairing the spark plug.
Description
The utility model relates to spark plug, particularly a kind of structure of easy removing sooting of the spark plug.
Spark plug is an engine ignitor, and the gaseous mixture of high-tension electricity in spark plug the two poles of the earth generation electric spark ignites cylinder makes engine operation.Be the space between spark plug two electrodes that use at present, along with the operating time prolongs, greasy dirt or carbon deposit between two electrodes, make the decline of insulating between two electrodes cause spark to die down, even do not produce electric spark, and this spark plug is removed the carbon deposit inconvenience, usually causes spark plug to scrap.
The purpose of this utility model is: design a kind of spark plug configuration of easy removing carbon deposit, can remove carbon deposit or greasy dirt between spark plug two electrodes easily, extending plug useful life improve reparation speed, alleviate maintenance load.
The purpose of this utility model is achieved in that the gap between former two electrodes of spark plug inserts insulating ceramics, and pottery becomes arc surface at the electrode ignition place.
As long as a kind of so novel spark plug configuration when sooting of the spark plug, is pulled down spark plug examination is wiped totally by the circular arc place, just can recover the spark plug operating state.
Fig. 1 is the utility model structural representation
Introduce the utility model technology contents and implementation method below in conjunction with accompanying drawing:
3 places, space between sparking-plug electrode 1 and 2 insert insulation porcelain pottery sintering, and make an arc surface structure 4 is arranged at the electrode ignition place, when greasy dirt or carbon deposit made that 4 places are dirty to cause that spark weakens between the electrode 1,2, as long as clean the greasy dirt or the carbon deposit at 4 places, spark plug just can be resumed work.
The utility model not only can be transformed existing spark plug and also can be produced in a large number by batch production.
Claims (1)
1, a kind of real core formula spark plug is characterized in that: 3 places, space between two electrodes 1,2 are filled with insulating ceramics and pottery forms arc surface 4 at two electrode ignition places.
