What are the two types of ignition systems commonly used in reciprocating engines?

In reciprocating engines, the two types of ignition systems most commonly utilized are magneto and battery ignition systems.

Magneto ignition systems are self-contained and do not require an external power source to operate. They generate high voltages through a rotating magnetic field and are prized for their simplicity and reliability, particularly in general aviation applications. This system ensures that the engine can be started and run independently of the aircraft's battery or electrical system, which is particularly advantageous in situations where the electrical system might fail.

Battery ignition systems, on the other hand, rely on a battery to provide the necessary voltage to create sparks at the spark plugs. These systems typically include components such as a distributor and ignition coil, which work together to step up the voltage and deliver it to the plugs at the correct timing. While they are more complex than magneto systems, they can provide enhanced features such as better control over timing and the ability to achieve more precise ignition performance, especially in larger or more sophisticated engines.

In contrast, the other options do not reflect common classifications of ignition systems in reciprocating engines. Carburetor and fuel injection systems relate to fuel delivery methods rather than ignition, while mechanical and electrical ignition systems are too broad and not specific to the widely accepted categories
