How often does the car ignition coil change?

I believe that most car owners are familiar with the ignition coil. The ignition coil controls the performance of the car as the core component of the car. So, how should the car ignition coil be maintained? Maintaining the good insulation performance of the ignition coil is the main content of its use and maintenance. Then we will introduce to you in detail how long the car ignition coil is changed and the main maintenance content of the ignition coil.

1. The connection between the ignition coil high-voltage lead screw and the high-voltage line should be firm and reliable. If the connection is loose, the discharge jumps easily, and the joint is burnt.

2. In some magnetic motor ignition systems, the ignition coil also maintains a prescribed clearance (air gap) with the rotating flywheel magnet, otherwise it will affect the ignition performance or cause mechanical accidents.

3. One end of the secondary winding of the ignition coil is connected to the spark plug through the high-voltage line and the spark plug cap, and the high-voltage line and the spark plug cap are prevented from being loosened during use.

The replacement of the ignition coil must be the same as the original basic model and the same as the original primary winding resistance. Using different types of ignition coils can damage other ignition components or cause new ignition coil failures. If an engine has a repeated ignition coil failure due to the replacement of the ignition coil, the ignition coil is difficult to operate, and the fundamental cause is usually a high secondary winding resistance or, in some cases, a lean fuel condition. The problem with avoiding the ignition coil is to clean the connector and terminal when a new ignition coil is installed. Corrosion can increase the resistance of the line causing intermittent operation and loss of continuity of operation and may contribute to electronic component damage. Applying non-conductive grease to the line connections can help prevent corrosion and ensure a good connection. On high-range engines with distributors or distributorless ignition systems, the spark plug wires should also be replaced with a bad ignition coil to ensure a high-energy spark.
