What is the function of the ignition system? What are the basic requirements of the ignition system?

1 The basic function of the ignition system: it can timely, accurately and reliably generate electric sparks in the cylinder to ignite the combustible mixture and make the gasoline engine do work under various working conditions and using conditions of the engine.

2 Basic requirements:

1) can generate enough voltage to break down the gap between the two electrodes of the spark plug.

2) EDM should have enough ignition energy.

3) The ignition time should be adapted to the working conditions of the engine.
