  Why does the ignition coil leak? Let's take a brief look at the ignition coil, a very important part of the ignition system. The ignition coil is a transformer with a primary winding inside, also called a primary winding, a secondary winding, also called a secondary winding, an iron core, an insulating material, etc. The ignition coil can convert a car's 12-volt voltage into a high voltage of 20,000 to 30,000 volts. The car ignition system uses this high-voltage electricity to ignite the mixture in the cylinder to provide power to the car.

  The primary coil current is controlled by the computer pulse to turn on and off. When it is turned on, the primary inductance converts electrical energy into magnetic energy in the magnetic core. This stage is the closing angle of the crankshaft, and the purpose is to store energy. The current cannot be too large, the time cannot be too long, otherwise, the coil will overheat and consume energy, the current cannot be too small, and the time cannot be too short, otherwise the energy storage is insufficient.

  When the current of the primary coil is interrupted, the magnetic energy is released in the secondary coil to generate a high voltage of 20kv~45kv. The primary generates a high voltage of more than 200V but there is no circuit and no energy consumption. The secondary high voltage is loaded. Combustible gas mixture.

  The working environment of the ignition coil is relatively harsh and needs to withstand high temperature and high pressure, so it is normal to wear and tear. If the ignition coil of poor quality is selected, the wear rate will increase, which will affect the vehicle power and ignition performance. Therefore, when replacing the ignition coil, we try to choose a better quality to avoid damage and leakage.

  For the ignition coil with slight current leakage, it can be solved by adding rubber pads: 1. You can first disassemble the line studs and clean them; 2. Use three rubbers as anti-leakage cushions. 3. Put the rubber pads on the bolts, then install the wires, and finally tighten the nuts with washers.

  However, when the leakage of the ignition coil is generally serious and the installation of rubber pads cannot be eliminated, it can be insulated by pouring pitch. The specific steps are 1. Use a thin iron sheet to make a slightly larger circle with the shape of the ignition coil. 2. Put the loop on the upper part of the coil and lead the three-wire joints out of the loop. 3. Pour the molten bitumen into it. After the bitumen is solidified, reinstall the thread. If the leakage is serious and the power of the car has been affected, it is recommended to replace it in time.
