目前,在国内汽车上使用最广泛的点火线圈,是两种感应式开启磁路的点火线圈,一种是无附加电阻的通式点火线圈,另一种是附有热变电阻的点火线圈.附加电阻经长时间的高温氧化,极易断裂,往往寿命比线圈短,因此必须修复使用.在《汽车电器》1966年第三、四期合刊刊登的“点火线圈附加电阻可以修复”一文中,介绍了点火线圈附加电阻损坏后自制代用的经验,即用直径φO.4毫米,长70—80厘米的低炭钢丝或其他任何一种钢丝保证电阻在1.25欧姆进行更换便可.现在我也谈谈自己的看法,与同志们商讨.
At present, the most widely used ignition coils in domestic automobiles are two types of ignition coils with inductively opened magnetic circuits, one is a general-purpose ignition coil without additional resistance, and the other is an ignition coil with a thermal resistor. Additional resistance by long-term high-temperature oxidation, easily broken, the life is often shorter than the coil, it must be repaired .In the “car electrical” 1966 third, fourth issue of “ignition coil additional resistance can be repaired” article , Describes the ignition coil additional resistance after the homemade substitute experience, that is, with diameter φ0.4 mm, 70-80 cm long low carbon steel wire or any other kind of steel to ensure that the resistance at 1.25 ohms can be replaced now I also Talk about your own views and discuss with your comrades.
