Technical field

The utility model relates to field of spark plugs, espespecially a kind of igniting effect that improves, the spark plug configuration of minimizing carbon distribution.

Background technology

Spark plug is the important composition parts of engine ignitor, spark plug is worked for a long time under HTHP, electrode easily produces carbon distribution, impact igniting, and in cylinder, produce a large amount of carbon distributions, gasoline combustion is insufficient, toxic emission increases, both waste fuel oil, increased again air pollution, shortened the useful life of spark plug and engine.

Utility model content

For addressing the above problem, the utility model provides a kind of igniting effect that improves, and reduces the structure-improved of the minimizing sooty plug of carbon distribution.

For achieving the above object, the utility model adopts following technical scheme to be: a kind of structure-improved that reduces sooty plug, comprises
