Motorcycle Ignition Coil High Voltage Coil Breakdown

Motorcycle Ignition Coil High voltage coil breakdown

The ignition coil causes damage

(1) the gap of spark plug electrode is too large, increasing the load of ignition coil, causing the high voltage coil to break through, causing short circuit or breaking.

(2) the engine overheats and the coil insulating varnish is baked and fails.

(3) the engine does not work, and the ignition switch is not shut off for a long time, because the thermal effect of the current damages the coil insulation in the ignition coil.

(4) high-voltage line breaks, resulting in high voltage, which can easily cause high pressure coil to be worn. When the engine is not easy to start, check whether the high voltage line is broken. In order to reduce the eddy current and its losses, it is usually used to replace the whole ignition coil core with the folded silicon steel sheet, which is the cut/laminated core, which includes the single phase and three phases. This kind of ignition coil core consists of iron core lamination, insulator and core structure. The structural parts include pull, pressing, clamping, gasket, brace, etc. These structures need to ensure the full clamping of the laminated sheet so as to form a complete and stable core structure of the ignition coil. The ignition coil can turn the low voltage of a car into a high voltage because it has the same form as a normal transformer, and the primary coils are larger than the number of turns in the secondary coil. But works on the ignition coil is different from the ordinary transformer, general transformer work 50 hz frequency are fixed, also called power frequency transformer, while work in the form of pulse ignition coil, can be seen as pulse transformer, it according to the different rotating speed of the engine at a different frequency for energy storage and put over and over again.

When the primary coil is connected to the power supply, a strong magnetic field is generated along with the current increase, and the core stores the magnetic field energy. When the switching device disconnects the primary coil circuit, the magnetic field of the primary coil declines rapidly, and the secondary coil induces a high voltage. The faster the magnetic field of the primary coil disappears, the greater the current disconnects the instantaneous current, and the larger the turn ratio of the two coils, the higher the voltage the secondary coil inducts.

Ignition can be fired in a dual cylinder and can be fired separately. The difference is whether to use a ignition coil. But the ignition coil works the same way. The coil type is also divided into magnetic and closed magnetic type, and usually the electronic ignition system adopts closed magnetic ignition coil.
