THIS IS OUT OF YOUR CONTROL - This 1 Cause of Ignition Coil Damage to Note.

Insulation surrounding the coil windings is essential for eliminating electrical shorts and guaranteeing dependable performance in small engine ignition coil production. However, when the manufacturer pours the dielectric glue to wrap the coils, tiny air bubbles may unintentionally occur within the insulation. As the resin hardens, these air bubbles get caught in it, creating air pockets inside the insulation. These air bubbles may look harmless, but when the ignition coil runs under typical engine conditions, they can be a serious problem.

Thermal expansion causes the trapped air in the insulation to expand when the coil heats up during operation. By opening up channels for electrical current to pass through the air bubbles, this expansion effectively shorts out the coil and impairs its operation.

Air bubbles in the insulation of ignition coils for small engines can damage the coil over time and cause performance problems. The heat produced by the electrical current passing through the coil when it is operating aggravates the trapped air bubbles in the insulation. This expansion reduces the insulation's resistance to voltage spikes and fluctuations in addition to raising the risk of electrical shorts.

As a result, the coil can suffer from random spark timing, sporadic misfires, or total ignition failure. In order to reduce these dangers and preserve the dependability of small engine ignition coils, producers must take careful quality control precautions during the resin encapsulating process.

Have a great day
