1, avoid long-term clean coke. Baotou North Benz accessories spark plug in use, the electrode and the skirt insulation experience had normal coke production, if these coke not long clean, will accumulate, eventually leading to the electrode leakage can not even jump. So should be regularly cleared coke, don’t wait for the spark plug to cleaning when not working.
2, avoid long-term use. Spark plug models are various, but have their own economic life, if more than the economic life is still used, will not be conducive to the engine’s power and economic performance. Studies have shown that, along with the extension of the spark plug use, the center electrode will change to arc shape, side electrode to the concave arc shape changes, the shape will make electrode gap increases, and cause discharge difficult, affecting the normal work of the engine.
3, avoid arbitrary scaling. Some people in the engine spray or other maintenance silver, do not pay attention to the appearance of the spark plug cleaning, the spark smudgy and leakage appearance. Clean appearance, can not figure is convenient and fast to use sandpaper, sheet metal cleaning, and should be the spark plug into gasoline, with brush to remove the spark plug, to ensure the appearance of ceramic body is not damaged.
4, avoid fire. In reality, some people often use coke burning to remove the spark plug electrode and the skirt and oil, this seemingly effective method, it is very harmful. Because of the fire, the temperature is difficult to control. It is very easy to burn the skirt insulator, causing the spark plug leakage, and after burning the small cracks are often not easy to find, to eliminate the trouble to bring a lot of trouble. Coke and oil the correct treatment of the spark plug is a special equipment for cleaning, there will be good results; two is the spark plug into the cleaning solution, soaking time of some alcohol or gasoline, when the coke after softening and then brush the hair net dry.
5, avoid hot and cold. In addition to the spark plug is different, the size of all kinds are divided into cold, heat medium, type three. General high compression ratio, high speed of the engine should be cold type spark plug, and low compression ratio, low speed of the engine should be used hot spark plug, between the two there are medium-sized spark plug. In addition, the new engine or overhaul of the engine and the spark plug of the old engine can be different according to the actual situation. For example, in a new engine, the spark plug should tend to heat; the old engine use time due to performance degradation, spark plug easy to produce too much Coke and oil pollution, selection of the spark plug tend to be medium or cold type, in order to improve the ability of anti oil spark plug.
6, avoid misdiagnosis and wrong. The replacement of the Baotou North Benz accessories spark plug or its suspected failure to check, should be a normal operation in the engine after parking flameout remove spark plug electrode to observe its color feature, can have the following conditions: one is the center electrode is red brown, and four side electrode spark plug for the selection of Zhou Chengqing gray, suitable; two is between the electrodes erosion or burning phenomenon, a white skirt and an insulator burning state, that spark plug selection overheating; three is between the electrode and insulator skirt with black stripes, the spark plug has leakage. Spark plug type selection is improper or leakage should be re select the appropriate spark plug.
7, do not install tight. Mercedes Benz accessories in the north of Baotou installation must comply with the requirements of the torque. With the special tool installation, normally does not exceed, but if the force is too large, excessive or wrench installation, often will damage the spark core or the screw buckle, expansion groove fracture caused spark plug scrap; but it can not be installed too loose, otherwise it will cause the engine not working properly.
