Capacitor discharge ignition pressure inside the cylinder. 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
Archaic Greece BC. Archaic Greece Archaic Greece was the period in Greek history lasting from the eighth century BC to the second Persian invasion of Greece in 480 BC, following the Greek Dark Ages and succeeded by the Classical period. The period began with a massive increase in the Greek population and a series of significant changes which rendered the Greek world at the end of the eighth century entirely unrecognisable compared to its beginning. According to Anthony Snodgrass, the Archaic period in ancient Greece was bounded by two revolutions in the Greek world. It began with a "structural revolution" which "drew
