Spark Plug Use Precautions

The spark plug is a part of the ignition system of the car. It is divided according to the heat value, and has a cold type and a hot type. According to the electrode material, there are nickel alloy, bismuth alloy and platinum;

Spark Plug Thread Repair Set Supplier to explain the spark plug disassembly precautions.

1. The screw, spark plug electrode and gasket must be kept clean and dry without oil. Otherwise, it will cause leakage, air leakage and spark reduction.

2. When removing the high-voltage cable connector, it should be gentle. Do not shake the spark plug insulator during operation, otherwise the spark plug sealing performance will be destroyed.

3. After the engine is cooled, it can be disassembled. When the spark plug to be disassembled is loosened, the dirt around the spark plug is blown one by one with a thin hose, and the dirt falls into the combustion chamber after the fire plug is unscrewed.

4. It should be tightened according to the required torque. If it is too loose, it will cause air leakage. If it is too tight, the gasket will lose its elasticity, which will also cause air leakage. Cone-type spark plugs are particularly important because they do not require a seal.

5. When installing, first align the spark plug with the sleeve with the screw hole, gently screw it in by hand, screw it to about 1/2 of the full length of the thread, and then fasten it with the force lever. If the hand feels poor when twisting, check whether it is entrained with impurities in the positive screw or thread. Do not blindly tighten the force to avoid damage to the screw hole, the cylinder head, especially the aluminum alloy cylinder head.
