Parallel-series electrode multigap energy-saving environmental-friendly spark plug

Abstract

The invention relates to a parallel-series electrode multigap energy-saving environmental-friendly spark plug. An iron shell is welded with two parallel type side electrodes keeping a proper spacing; a porcelain core is respectively provided with one central electrode and one bridging type central electrode, and the upper ends of the central electrode and the bridging type central electrode are both exposed out of a porcelain surface; and gaps among electrodes are all in a series structure. By adopting the technical scheme and especially after the central electrodes are changed into square flat shapes and have edge type marginal discharge, the invention enhances the arc-through capability, reduces the load of an ignition system, improves the burning velocity of a mixed gas, and prolongs the service life of related parts; sparks generated among the electrodes are all directly exposed in the mixed gas, therefore, the ignition energy loss is reduced, and the burning efficiency of the mixed gas is enhanced; jump-spark gaps are increased, therefore, the gap free adjustment is realized; and the two central electrodes are in the square flat shapes and are relatively enlarged in cross sectional areas, therefore, the service life of the spark plug is prolonged. Thus, the invention more enables the mixed gas to be sufficiently burned, saves fuel, reduces cost and pollution, and enhances the power of a motor.

Description

technical field [0001] The invention belongs to accessories of gasoline or gas internal combustion engines, in particular to an energy-saving and environment-friendly spark plug in parallel series with a large number of gaps. technical background [0002] At present, most of the spark plugs at home and abroad are single-point "ignition", that is, spark plugs with a single center electrode structure, and some use multi-pole spark plugs. The single center electrode spark plug has only one "ignition" point. Although it can achieve the ignition task, due to the weak ignition intensity and poor reliability, the combustion of the mixture in the engine cylinder is insufficient. For multi-side electrode spark plugs, since the multiple side electrodes are all connected in parallel, and the spark gaps cannot be made completely equal, it can only flash from the closest gap, and it is impossible to achieve simultaneous continuous connection between multiple side electrodes and a center ...

AI Technical Summary

Problems solved by technology

However, since the central electrode and the bridging central electrode are both cylindrical, according to the principle of discharge at the tip of the conductor, it is relatively difficult to discharge the spark plug electrode; and because the two central electrodes of the patent are affected by the size of the insulating porcelain Restrictions, the use of economical materials can not be made very thick, with the long-term discharge loss of the spark plug electrode in the engine cylinder and the ablation of the high-temperature, high-pressure mixture, and the spark plug of this patent has only one side electrode, the effective between the electrodes The ignition gap increases relatively accordingly

Therefore, the ignition reliability of the patented spark plug and the free adjustment of the electrode gap during use are affected to varying degrees.
