  • 火花塞的结构和耐温
  • 本站编辑:杭州尚逸汽车用品有限公司发布日期:2018-04-10 17:40 浏览次数:

火花塞中间金属壳体和陶瓷体部分,通常是低于100℃的(或100℃左右),这是由于火花塞紧密接触在缸盖上,传导热量很快的金属缸盖和水循环带走了80%的热量,发动机水温嘛,你是知道的,正常都在100℃以下,100℃以上那叫开锅&。

The middle metal shell and the ceramic body part of the spark plug, usually below 100 degrees C (or about 100 degrees C), is due to the close contact of the spark plug on the cylinder head, which carries a fast heat metal cylinder head and the water cycle to take away 80% of the heat. The engine water temperature, you know, is often below 100, and more than 100 degrees centigrade. Boil.

下图为某型号发动机冷却液循环图,为了图示一下,每个缸都是有水套的,每个气缸都是可以被流动的冷却液(水)带走的热量的&。

The following figure is a cycle diagram of a certain type of engine coolant. In order to illustrate, each cylinder has a water jacket and each cylinder is the heat that can be taken away by the liquid coolant (water).

火花塞工作的温度,基本上是指火花塞裙部的温度,就是火花塞电极端及电极旁边的陶瓷体尖端那一整块的温度&。

The temperature of the spark plug basically refers to the temperature of the spark plug skirt, that is the extreme temperature of the spark plug and the temperature of the ceramic body near the electrode.

火花塞正常的工作范围是500℃到850℃,超过约900℃-1000℃,就会到自燃区域,也就是说,火花塞还没开始放电点火,汽油就提前被点燃了,就可能引起了爆震&。

The normal operating range of the spark plug is 500 degrees C to 850 C, more than 900 C -1000 C, and it will go to the spontaneous combustion zone, that is to say, the spark plug has not begun to discharge and ignites, and the gasoline is ignited in advance, which may cause a detonation.

所以火花塞有热值,热值的本质是火花塞能够承受或带走的比较大热量&。

So the spark plug has calorific value. The essence of the calorific value is the maximum heat that the spark plug can bear or take away.

如果车辆使用了过低热值的火花塞,火花塞就会太热了,可能会爆震连连;

If a vehicle uses a spark plug with too low calorific value, the spark plug will be too hot, and it will probably knock.

如果车辆使用了过高热值的火花塞,火花塞不存热,工作的温度就有可能会低于500℃,工作不良,汽油不能顺利燃烧,造成火花塞积碳&。

If the vehicle uses a spark plug with high heat value and the spark plug does not keep the heat, the temperature of the work may be less than 500 degrees centigrade, the work is bad, the gasoline can not burn smoothly, causing the carbon of the spark plug.

缸盖上,很容易就散热到100℃以下了(或左右)&。

On the cylinder head, it is easy to heat up to below 100 degrees (or left or right).

火花塞的热值通常是用陶瓷的大小和粗细形状来做调节的,陶瓷多,散热慢,热值就低,陶瓷少,散热快,热值就高&。

The heat value of the spark plug is usually adjusted by the size and the shape of the ceramic. The ceramic is more, the heat dissipation is slow, the heat value is low, the ceramics are less, the heat dissipation is fast, and the heat value is high.
