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 smile Archaic smile The Archaic smile was used by Greek Archaic sculptors, especially in the second quarter of the 6th century BCE, possibly to suggest that their subject was alive, and infused with a sense of well-being. One of the most famous examples of the Archaic Smile is the Kroisos Kouros. The dying warrior from the west pediment of the Temple of Aphaia, Aegina, Greece is an interesting context as the warrior is near death. In the Archaic Period of ancient Greece (roughly 600 BCE to 480 BCE), the art that proliferated contained images of people who had the archaic smile.
