How Does a Car Engine Start Ignition?
The Ignition System
The ignition system is responsible for creating the spark that ignites the fuel in the engine’s cylinders. It consists of the following components:
- Battery: The battery provides the electrical power for the ignition system.
- Ignition switch: The ignition switch turns on the ignition system when the key is turned to the “on” position.
- Ignition coil: The ignition coil increases the voltage of the electricity from the battery to create the spark.
- Distributor: The distributor distributes the spark to the spark plugs.
- Spark plugs: The spark plugs create the spark that ignites the fuel in the cylinders.
The Ignition Process
When the ignition switch is turned to the “on” position, the battery sends electricity to the ignition coil. The ignition coil increases the voltage of the electricity to create the spark. The distributor then distributes the spark to the spark plugs. The spark plugs create the spark that ignites the fuel in the cylinders.
Troubleshooting Ignition Problems
If your car is having problems starting, the ignition system may be the culprit. Here are some common ignition problems and their symptoms:
- Dead battery: A dead battery will prevent the ignition system from receiving power.
- Faulty ignition switch: A faulty ignition switch may not allow the ignition system to turn on when the key is turned.
- Bad ignition coil: A bad ignition coil may not be able to create enough voltage to create a spark.
- Faulty distributor: A faulty distributor may not be able to distribute the spark to the spark plugs.
- Fouled spark plugs: Fouled spark plugs may not be able to create the spark needed to ignite the fuel.
If you are having problems starting your car, it is important to have the ignition system checked by a qualified mechanic.
