Spark plug insulator between the electrode tip and sometimes sticky deposits, many owners tend to ignore these deposits, but deposits on the spark plug does not know if serious spend is likely to cause serious consequences of the engine does not work. However, the formation of deposits for different reasons are different, we should distinguish the root cause of the failure to do the right medicine.
(1), oily deposits
**** Have oily deposits on the spark plug, indicating the lubricant into the combustion chamber. If only the individual spark plugs, there may be damage to the valve stem seals; but if the spark plugs of each cylinder are sticky deposits, then this, then there may be a cylinder channeling oil, it is recommended to check the air filter and ventilation is blocked.
(2), black sediment
**** If the spark plug electrode and the internal black sediment, indicating that there may be a rich mixture, in which case the running speed of the engine can be increased, and for a few minutes, the electrodes can be burned remain in the layer of black soot layer .
*
3, ignition tip part of the physical damage
**** Bending performance of the electrodes of the spark plug, the bottom of the insulator is damaged, and several pits appear on the electrodes.
This situation is mainly due to the spark plug screws protruding from the front of the engine with Audi A4 h beam conrods for too long, or the combustion chamber of a foreign body, such as small screws nuts, etc., constitute damage to the spark plug.
Above situation can basically deal with the naked eye, you can periodically check the owner's own car spark plug, if you find a problem to be treated promptly, so that not only help extend the life of the spark plug, but also more conducive to your use vehicle safety.
