Capacitor discharge ignition Capacitor discharge ignition Capacitor discharge ignition (CDI) or thyristor ignition is a type of automotive electronic ignition system which is widely used in outboard motors, motorcycles, lawn mowers, chainsaws, small engines, turbine-powered aircraft, and some cars. It was originally developed to overcome the long charging times associated with high inductance coils used in inductive discharge ignition (IDI) systems, making the ignition system more suitable for high engine speeds (for small engines, racing engines and rotary engines). The capacitive-discharge ignition uses capacitor discharge current to the coil to fire the spark plugs. The history of the capacitor discharge ignition system can
Ignition SCADA tags as well as altering the logging rate dynamically. This allows the system to store high resolution history when needed, but lower resolution data for other periods. The system automatically partitions data into multiple database tables. This accomplishes two functions: ensures consistent performance over the long term, and provides a consistent mechanism for data archival and pruning. The Ignition platform uses scripting to allow designers to add flexibility and customization. There are two major scripting languages in Ignition, Python and the "Expression Language". Ignition uses an implementation of Python version 2.5 called Jython. Python script is used for component Event
