I believe many people are unsurse about use apark plug,but don't worry about this. After read this article,you can learn a lot.
There are 7 tips you should know:1, to avoid long-term dirty coked. In use, the spark plug electrode and the skirt portion insulator have a normal soot generated if these soot long are not clean, will be piled up, and ultimately lead to the electrode leakage can not even sparkover.
1. Coke should be removed regularly, clean only Do not wait for the spark plug does not work. Automotive spark plug the seven taboo Bluebird use exhaust side spark plugs are not sparking failure
2. to avoid long-term use. Spark plug model range, but has its own economic life, still use, if it exceeds the economic life of the engine power and economy is not conducive to play. Research has shown that, as to extend the period of the spark plug using the center electrode end face will change to the arc shape, the side electrode to a concave arcuate shape changes, this shape will make the electrode gap increases, and causing the discharge difficult, affect the engine work properly.
3. avoid random descaling. Some people spray silver or other maintenance on the engine, do not pay attention to the spark plug clean appearance, resulting in a spark plug gets dirty and leakage. Clean appearance, not convenience, efficient use of sandpaper, sheet metal descaling, the spark plug should be immersed in gasoline to be removed with a brush, to ensure that the spark plug appearance ceramic body from damage.
4. avoid fire. In reality, some people often use fire way to clear the spark plug electrode and the skirt of coke and oil, this seemingly effective way, in fact, is very harmful. The temperature is difficult to control because the fire. Easily skirt insulator burn crack, causing the spark plug leakage and fire after hairline cracks are not always easy to troubleshoot a very ** annoying. Correct processing method of coke and oil on the spark plug first, using special equipment to clean, have a good effect; solution to clean the spark plug into soaked in alcohol or gasoline in a certain time, then when the carbon deposition softening with hair brush net to dry.
5. avoid hot and cold, regardless. Spark plugs in addition to a different shape, different sizes, divided into cold type, medium, hot three. Generally high compression ratio, high-speed engine is suitably cold type spark plug; rather low compression ratio, low-speed engines suitably hot type spark plugs in between medium-sized spark plug. In addition, the new engine or overhaul the engine and the old engine spark plug selection may vary according to the actual situation. For example, when the engine is newer selection of spark plugs should tend to heat type; the using time principals Old engine performance degradation, spark plugs prone to excessive carbon deposits and oil defaced selection of spark plugs should tend medium-sized or cold, in order to improve the spark plug the ability to anti-oil pollution.
6. avoid misdiagnosis faulted. Replace the spark plug or suspected failure need to check, it should be after a period of normal operation of locomotive parking stall Remove the spark plug to observe the color characteristics of the electrode, may have the following situations: First, the center electrode reddish brown, next to the electrode and four Zhou Chengqing gray, suitable for spark plug selection; inter-electrode ablation or Shaorong phenomenon was blanch white skirt and insulators, the Description spark plug selection overheating; between the electrodes and insulator skirt with black stripes description of the spark plug leak. The spark plug selection of inappropriate or leak should be re-select the appropriate spark plug.
7.bogey installed too tight. Spark plug installation must comply with the specified torque. Use special tools to install, generally not more than, but if force is too large, too fast or with a box wrench installation, you often will damage the spark plug ceramic core or screw slider to expansion slots fracture and lead to the spark plug scrapped; but also can not be installed too loose, otherwise it will cause the engine is not working properly.
