What does a CDI unit do?

A capacitor discharge ignition (CDI) unit is an electronic device that provides the high voltage necessary to create a spark in a spark plug. It is used in internal combustion engines, such as those found in motorcycles, cars, and lawn mowers.

The CDI unit consists of a capacitor, an ignition coil, and a switch. The capacitor is charged by the battery, and when the switch is closed, the capacitor discharges its energy through the ignition coil. This creates a high voltage pulse, which is then sent to the spark plug.

The CDI unit is a more efficient and reliable way to create a spark than the traditional ignition system. It also produces a hotter spark, which can help to improve engine performance.

Here are some of the advantages of using a CDI unit:

* Improved engine performance: The hotter spark produced by a CDI unit can help to improve engine performance, such as increasing power and fuel efficiency.

* Reduced emissions: The CDI unit can help to reduce emissions by ensuring that the fuel is burned more efficiently.

* Increased reliability: The CDI unit is a more reliable way to create a spark than the traditional ignition system, which can help to reduce the risk of engine problems.

* Cost-effectiveness: The CDI unit is a cost-effective way to improve engine performance and reliability.

If you are looking to improve the performance of your internal combustion engine, a CDI unit is a great option. It is an efficient, reliable, and cost-effective way to create a spark.
