what's spark plug leakage?


Spark plug leakage, professional called flashover, also known as creepage, arc, popular term for 


breakdown.Flashover refers to the phenomenon of discharge on the surface of a solid insulator when 


a gas or liquid dielectric is punctured around a solid insulator.


Some of the spark plug replacement and flashover present a very clear line, individual does not know 


customized Laser Iridium Spark Plug For Toyota auto repair work or the type of car repair work, will tell 


the owner spark plug has the crack, is cracked.Distinguish flashover or crack? The simplest method is to


find a piece of sandpaper, the flashover is on ceramic surface, grind a few to be able to wear off, the crack 


cannot grind away.Flashover is one or more black marks, some thick, some fine, some are multi-line 


segments, different shapes.

Spark plug flashover cause:


1. The breakdown voltage of wholesale customized spark plug is larger due to excessive clearance;


2. There is a conductive stain on the ceramic insulator of spark plug due to the pollution or oil leakage 


during installation;


3. The ignition coil (or cylinder line) rubber sleeve is worn due to high temperature aging and cracks in the 


inner wall;When the above 3 points satisfy at least 1, the high-voltage piezoelectric does not discharge from 


the positive and negative electrode of the spark plug, and the path is discharged from the ceramic insulator 


of the spark plug to the shell, forming flashover.


4, spark plug center electrode ceramic insulators (commonly known as ceramic capitulum) here, if because 


ceramic capitulum causes abnormal shape and so on carbon deposition is more, or because of gasoline 


contains the metal additives such as MMT cause residues in attachment in ceramic small head, and can 


also cause ceramic small head arc ignition.
