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 globalization cultural backgrounds could meet and interact. These trading routes were the communication highways for the ancient civilizations and their societies. New inventions, religious beliefs, artistic styles, languages, and social customs, as well as goods and raw materials, were transmitted by people moving from one place to another to conduct business. Proto-globalization is the period following archaic globalization which occurred from the 17th through the 19th centuries. The global routes established within the period of archaic globalization gave way to more distinguished expanding routes and more complex systems of trade within the period of proto-globalization. Familiar trading arrangements such as the
