There are several types of faults related to spark plugs:

2023-09-12

Based on the symptoms of spark plug erosion and changes in color, the specific cause of this malfunction can be identified.
(1) The electrode melts and the insulator turns white;
(2) The electrode is rounded and the insulator has scars;
(3) Insulator tip fragmentation;
(4) The top of the insulator has gray black stripes;
(5) Dissolution damage to the installation screws of the mechanical box;
(6) Damaged cracks at the bottom of the insulator;
(7) The central electrode and grounding electrode are dissolved or burned out, and the bottom of the insulator is in granular form with metal powders such as aluminum attached;
2. Spark plug has deposits
(1) Oily sediment;
(2) Black sediment;
3. Physical damage to the ignition tip
This is manifested by the bent electrode of the spark plug, damage to the bottom of the insulator, and multiple dents appearing on the electrode.
The above situations can be observed and handled with the naked eye. Car owners can regularly check their own spark plugs and promptly handle any problems found. This not only helps to extend the service life of the spark plugs, but also is more conducive to vehicle safety.
