汽车的部件对行车却有着关重要的作用，或者能影响汽车的制动性、油耗，有的甚影响车主的生命。那么，不同车部位如何保养呢？下面济南沃尔沃汽车专修厂家先来讲讲火花塞保养方法。

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、忌长期不清洁积炭。火花塞在使用中，其电极及裙部绝缘体会有正常的积炭产生，如果这些积炭长期不予清洁，会越积越多，更终导致电极漏电甚不能跳火。所以应定期积炭，不要等火花塞不工作时才进行清洁。汽车火花塞在使用中的七个大忌蓝鸟排气侧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、忌长期使用。火花塞型号繁多，但都有自己的经济寿命、如果超过经济寿命后仍然使用，将不利于发动机的动力性和经济性的发挥。有研究表明，随着火花塞使用期的延长，其电极端面会向圆弧形状变化，侧电极则向凹弧形状变化，这种形状将使电极间隙增大，并造成放电困难，影响发动机的正常工作。

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、忌随意除垢。有些人在对发动机喷银粉或进行其它维护时，不注意火花塞外表的清洁，致使火花塞因外表脏污而漏电。清洁外表时，不可图方便、快捷使用砂纸、金属片等除垢，而应当把火花塞浸入汽油中，用毛刷予以，以确保火花塞外表陶瓷体不受损伤。

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、忌火烧。现实中，有些人常常用火烧的办法来火花塞电极及裙部的积炭和油污，这种看似有效的方法，其实是十分有害的。因为火烧时，温度难于控制。很容易将裙部绝缘体烧裂，造成火花塞漏电，而且火烧后产生的细小裂纹往往不易发现，给排除故障带来很大麻烦。

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.

此外火花塞安装时一定要符合规定的扭矩。用专用工具安装时若用力过大、过猛或用梅花扳手安装时、则常会损伤火花塞瓷芯或使螺丝滑扣，膨胀槽断裂而导致火花塞报废；但也不可安装过松，否则会造成发动机工作不正常。关注我们网站http://www.lutongqixiu.com，了解更多事项！

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.
