  • 点火线圈是什么你知道吗?
  • 本站编辑:杭州尚逸汽车用品有限公司发布日期:2018-07-06 15:41 浏览次数:

在发动机轻改方面,很多人都会对点火系统进行改动。首先想到的就是更换高性能火花塞,但当更换火花塞之后,如果点火线没能跟上,提供不了足够的电压也是枉然。所以说,改装点火线也是发动机点火系统改装的重要一环。 点火线,英文为Ignition Coil,又叫做分火线、分缸线、点火线圈。主要是负责分配点火顺序,把分电器预先分配好的高压电传递到火花塞使汽缸内部点燃的一种传递介质。按照发动机的缸数决定点火线的条数,每一条点火线的一侧是连接带有点火线圈的火花塞,另外一侧连接着分火器。不同的点火线有着不同的线芯,一般有铜芯和炭精芯,同时,不同的车辆,其点火线会有不同的长度。不同的火花塞其接线端也会有所不同。 材质结构,一般的汽车点火线采用硅胶绝缘技术,使用温度在-40-220摄氏度,比较大承受电压为35kV。线芯多采用硅胶导体,电阻比较稳定。从线芯结构上看,点火线有单线芯、3线芯、4线芯和5线芯等。线芯越多其电阻也就先对较小、点火强度也就相应的高,但线芯太多,也就会导致电流过大,所以会对点火线的包装和屏蔽的材料有着特殊的要求。2-1F51G54932-50.jpg

     In the light of engine modification, many people will change the ignition system. The first thing to think about is to replace the high performance spark plug. But if the spark plug is replaced, if the ignition line is not able to catch up, it will be useless to provide enough voltage. Therefore, retrofitting ignition line is also an important part of engine ignition system modification. The ignition line, Ignition Coil, is also known as the ignition line, the cylinder line and the ignition coil. It is mainly responsible for distributing the ignition sequence and transmitting the high voltage electricity which is pre allocated by distributor to a transfer medium ignited by the spark plug. The number of points of the fire line is determined according to the number of cylinders of the engine. One side of each point of the fire line is the spark plug with the ignition coil, and the other side is connected with the firearm. Different ignition lines have different wire cores, usually copper core and carbon core. At the same time, the ignition lines of different vehicles will have different lengths. The terminals of different spark plugs will also be different. Material structure, the general car ignition line adopts silica gel insulation technology, the use temperature is -40-220 degrees Celsius, the maximum withstand voltage is 35kV. The core is mostly silicone conductor, and the resistance is relatively stable. From the core structure, ignition line has single core, 3 wire core, 4 wire core and 5 wire core. The more the wire core has its resistance to the smaller, the ignition intensity is also high, but the core is too much, it will lead to excessive current, so it will have special requirements for the packaging and shielding materials of the ignition line.


根据我国的国家标准GB/T 14820-2009规定了点火线的技术指标,其中包括外观线体表面光滑、平整及色泽均匀,护套表面无缺陷;插、拔力为分电器和火花塞都为35N-70N;阻尼线电阻值,其中电阻型点火线为16千欧,正负30%,电抗型点火线为0.5千欧-16千欧;绝缘强度是利用30kV的电压,在1小时内无击穿状况;模拟点火,在50Hz、29kV的通电状况下,30秒钟内没有漏电和击穿;线体与端子的拉力必须大于等于100N;使用温度范围必须在-40~200摄氏度之间。

     According to the national standard GB/T 14820-2009 of our country, the technical specifications of the point fire line are stipulated, including smooth surface, smooth surface and uniform color and no defect on the surface of the sheath; the insertion and pulling force for the distributor and the spark plug are all 35N-70N; the resistance value of the damping line, of which the electrical resistance ignition line is 16 thousand, positive and negative 30%, reactance type The ignition line is 500 EU -16 kilo; the insulation strength is the voltage of 30kV and no breakdown in 1 hours. Under the condition of 50Hz and 29kV, the analog ignition does not leak and breakdown within 30 seconds; the tension of the line and terminal must be greater than equal to 100N; the use temperature range must be between -40~200 degrees Celsius.
