What is the cause of spark plug failure

The fault of the spark plug of the car is because the spark plug of the car is worn or carbon deposits, or the gap of the spark plug of the car is too large, which leads to the failure of the car such as increased fuel consumption, weak driving, and unqualified exhaust emissions.

　　

The spark plug discharges the high-voltage electricity sent by the high-voltage wire, and generates an electric spark in the air between the two electrodes of the engine to ignite the mixed gas in the cylinder. Spark plugs are mainly divided into quasi-type spark plugs, electrode-type spark plugs, seat-type spark plugs, etc., by introducing high-voltage electricity into combustion to generate electric sparks, ignite the mixed gas, and cooperate with the ignition system and fire supply system to make the engine do work, so to a large extent The upper spark plug determines the performance of the engine. The quasi-type spark plug is the most widely used spark plug, and the electrode-type spark plug has very thin electrodes, strong sparks, and excellent ignition performance.
