The importance of spark plug cleaner

1, avoid long-term not cleaning coke

The spark plug is in use, the electrode and the skirt insulation experience had normal coke produces, if these microactivity not long clean, will accumulate, which eventually led 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.truck tyre

2, avoid long-term use

Spark plug type is various, but all have their own economic life, if still use more than economic life, will not be conducive to give full play to the engine performance and fuel economy. Research has shown that along with the prolonging of spark plugs use period, the center electrode face will change to the arc shape, the 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 random descaling

Some people in the engine spray or other maintenance silver, do not pay attention to the spark plugs of clean appearance, the spark smudgy and leakage appearance. Clean appearance, not map easily, and quick to use sandpaper, sheet metal cleaning, and should be the spark plug immersion in gasoline, to be removed with a brush, to ensure that the spark plug ceramic body appearance is not damaged.

4, avoid the fire

In reality, some people often use coke burning them to remove the spark plug electrodes and skirt and oil, this seemingly effective method, is actually very harmful. Because the fire, difficult temperature control. It is easy to skirt insulator firing crack, cause the spark plug leakage, small cracks and after the fire there are often difficult to find, to eliminate the fault cause a lot of trouble. Coke and oil the correct treatment of the spark plug is special equipment for a clean, there will be good results; two is the solution to clean, will spark plug into the soaking time of some alcohol or gasoline, when the coke softened then brush brush to dry.

5, avoid cold and hot points

Spark plug in addition to different shape, size of each big, is divided into cold type, medium, heat type three. General high compression ratio, high rotating speed engine should use cold type spark plug; and low compression ratio, low rotating speed engine should use hot spark plug, and a medium between the spark plug. In addition, the spark plug type selection of the new engine or engine overhaul and the old engine according to the actual situation may be different.

6, avoid the misdiagnosis and wrong fault

New spark plugs or its suspected fault need to check, should be a period of normal operation in the locomotive, parking flameout remove the spark plug electrodes to observe its color feature, can have the following conditions: one is the center electrode is reddish brown, a side electrode and was surrounded by a green gray, spark plug suitable for selection; two is the inter electrode ablation or melt, skirt and insulators are burning white state, that spark plug selection overheating; three is between electrode and insulator skirt with black stripes, that spark plug has leakage. Spark plug improper selection or leakage should be re select the appropriate spark plug.
