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
Archaic Greece its connotations in English of being primitive and outdated. No term which has been suggested to replace it has gained widespread currency, however, and the term is still in use. Much of our evidence about the Classical period of ancient Greece comes from written histories, such as Thucydides' History of the Peloponnesian War. By contrast, we have no such evidence from the Archaic period. We have written accounts of life in the period in the form of poetry, and epigraphical evidence, including parts of law codes, inscriptions on votive offerings, and epigrams inscribed on tombs. However, none of this evidence
