12. Ignition system maintenance

Chapter 12 of our vehicle maintenance guide covers a crucial component of your car: the ignition system. This system is responsible for starting the process that gets your car running. It generates a spark that ignites the mixture of air and fuel in your car's engine, which results in combustion that powers the engine. Proper maintenance of this system is essential to ensure your car runs efficiently and safely.

Ignition System Components

The ignition system is made up of several parts, each playing an important role. These include the ignition key, ignition switch, ignition coil, spark plugs, distributor and spark plug wires. Each of these components needs to be maintained in good condition to ensure the ignition system works properly.

Ignition Key Maintenance

The ignition key is the device you use to start the ignition process. Over time, the key can wear out, which can make it difficult to start the engine. If the key is worn or damaged, you may need to replace it.

Ignition Switch Maintenance

The ignition switch is what transmits current from the car battery to the rest of the ignition system. If the switch is faulty, it may prevent the car from starting. Ignition switch maintenance usually involves replacing it.

Ignition Coil Maintenance

The ignition coil is what generates the high voltage needed to create the spark that starts combustion. If the ignition coil is faulty, it can result in poor or non-existent ignition. Ignition coil maintenance usually involves replacement.

Maintenance of Spark Plugs

Spark plugs are what actually produce the spark that starts combustion. They can wear out over time and need to be replaced regularly. Spark plug maintenance involves checking their condition, cleaning and, if necessary, replacing.

Distributor Maintenance

The distributor is what distributes the high voltage current from the ignition coil to the spark plugs in the correct order. If the distributor is faulty, it can result in an erratic ignition. Distributor maintenance usually involves replacing it.

Maintenance of Sail Wires

The spark plug wires are what transmit the high voltage current from the ignition coil to the spark plugs. If the wires are damaged or frayed, they can prevent current from reaching the spark plugs, which can result in poor or no ignition. Maintenance of spark plug wires usually involves replacing them.

Conclusion

Proper maintenance of the ignition system is essential to ensure your car runs efficiently and safely. This involves regularly checking and replacing worn out or damaged components. By keeping your ignition system in good condition, you can extend your car's lifespan and avoid costly problems down the road.
