What are the breaker points and condenser connected in an ignition system?

The ignition system in internal combustion engines is responsible for generating the high-voltage spark that ignites the fuel-air mixture in the combustion chamber. Two crucial components within this system are the breaker points and the condenser, both of which play essential roles in the process.

1. Breaker Points:

- The breaker points, also known as contact breakers, are mechanical switches located in the distributor cap of the ignition system.

- Their primary function is to regulate the flow of electricity from the ignition coil to the spark plug.

- When the engine is running, the distributor's camshaft rotates and periodically opens the breaker points. This interruption in the electrical circuit creates an essential condition for generating a high-voltage spark.

2. Condenser:

- The condenser (or capacitor) is an electronic component connected across the breaker points.

- It acts as an energy storage device, temporarily storing the electrical energy released when the breaker points open.

- By absorbing and releasing this energy, the condenser helps prolong the duration of the spark produced by the ignition coil. This extended spark duration improves combustion efficiency, especially at higher engine speeds.

- Additionally, the condenser helps protect the breaker points from excessive arcing and erosion, extending their lifespan.

In summary, the breaker points are responsible for interrupting the electrical circuit, while the condenser stores and releases energy to enhance spark duration and protect the breaker points. These two components work together to ensure efficient ignition and smooth engine operation. However, modern vehicles commonly employ electronic ignition systems, eliminating the need for mechanical breaker points and condensers, offering improved reliability and efficiency.
