汽車的部件對行車安全卻有著至關重要的作用，或者能影響汽車的制動性、油耗，有的甚至影響車主的生命安全。那么，不同車部位如何保養呢？下面濟南沃爾沃汽車專修廠家先來講講火花塞保養方法。

The components of a car play a vital role in driving safety, or can affect the braking performance, fuel consumption, and even the life safety of the car owner. How to maintain different parts of the car? Next, the specialized repair manufacturer of Volvo Cars in Jinan will first talk about the maintenance methods of spark plugs.

1、忌長期不清潔積炭。火花塞在使用中，其電極及裙部絕緣體會有正常的積炭產生，如果這些積炭長期不予清潔，會越積越多，更終導致電極漏電甚至不能跳火。所以應定期清除積炭，不要等火花塞不工作時才進行清潔。汽車火花塞在使用中的七個大忌藍鳥排氣側火花塞不打火花的故障。

1. Do not clean the carbon deposit for a long time. During the use of spark plugs, the insulation of their electrodes and skirts will have normal carbon deposits. If these carbon deposits are not cleaned for a long time, they will accumulate more and more, which will eventually lead to electrode leakage or even spark over. Therefore, the carbon deposit shall be removed regularly, and the spark plug shall not be cleaned until it is not working.

2、忌長期使用。火花塞型號繁多，但都有自己的經濟壽命、如果超過經濟壽命后仍然使用，將不利于發動機的動力性和經濟性的發揮。有研究表明，隨著火花塞使用期的延長，其電極端面會向圓弧形狀變化，側電極則向凹弧形狀變化，這種形狀將使電極間隙增大，并造成放電困難，影響發動機的正常工作。

2. Avoid long-term use. There are many types of spark plugs, but they all have their own economic life. If they are still used beyond the economic life, it will be detrimental to the engine's power and economy. Some studies have shown that with the extension of the service life of spark plugs, the end face of the central electrode will change to the arc shape, and the side electrode will change to the concave arc shape. This shape will increase the electrode gap, cause difficult discharge, and affect the normal operation of the engine.

3、忌隨意除垢。有些人在對發動機噴銀粉或進行其它維護時，不注意火花塞外表的清潔，致使火花塞因外表臟污而漏電。清潔外表時，不可圖方便、快捷使用砂紙、金屬片等除垢，而應當把火花塞浸入汽油中，用毛刷予以清除，以確保火花塞外表陶瓷體不受損傷。

3. Do not remove dirt at will. Some people do not pay attention to the cleanness of the spark plug appearance when spraying silver powder or performing other maintenance on the engine, which causes the spark plug to leak electricity due to its dirty appearance. When cleaning the surface, it is not allowed to use sandpaper, metal chips, etc. conveniently and quickly for descaling. Instead, the spark plug should be immersed in gasoline and removed with a brush to ensure that the ceramic body on the surface of the spark plug is not damaged.

4、忌火燒。現實中，有些人常常用火燒的辦法來清除火花塞電極及裙部的積炭和油污，這種看似有效的方法，其實是十分有害的。因為火燒時，溫度難于控制。很容易將裙部絕緣體燒裂，造成火花塞漏電，而且火燒后產生的細小裂紋往往不易發現，給排除故障帶來很大麻煩。

4. Avoid burning. In reality, some people often use the method of burning to remove the carbon deposits and oil stains on the spark plug electrode and skirt. This seemingly effective method is actually very harmful. Because the temperature is difficult to control when the fire burns. It is very easy to burn the insulator of the skirt, causing electric leakage of the spark plug, and the small cracks generated after the fire are often difficult to find, which brings great trouble to troubleshooting.

此外火花塞安裝時一定要符合規定的扭矩。用專用工具安裝時若用力過大、過猛或用梅花扳手安裝時、則常會損傷火花塞瓷芯或使螺絲滑扣，膨脹槽斷裂而導致火花塞報廢；但也不可安裝過松，否則會造成發動機工作不正常。關注我們網站http://www.coqenpate.cn，了解更多事項！

In addition, the spark plug must be installed in accordance with the specified torque. When installing with special tools, if the force is too large or too strong, or when installing with a box wrench, the ceramic core of the spark plug will be damaged or the screw will slip, and the expansion groove will be broken, resulting in the scrapping of the spark plug; However, do not install too loosely, or the engine will not work properly.
