DISTRIBUTORLESS IGNITION SYSTEM (DIS)
Definition: An ignition system that does not use a distributor to route high voltage to the spark plugs. The high voltage plug wire runs directly from the ignition coil to the spark plug. Some DIS systems have one coil for every two spark plugs (a shared system), while others have a separate coil for each spark plug (See Coil-Pack below). Eliminating the distributor makes the system more reliable and eliminates maintenance.
Coil Pack - The function of any ignition coil is to convert a low voltage, usually 12 volts, into a voltage high enough, 35,000 volts and up, to jump the spark plug gap and ignite the fuel-air mixture in the combustion chamber. It performs this function by making use of the principle of induction. The inside of a coil consist of primary and secondary windings of wire coiled around a vertically mounted soft-iron core. Because of the ratio of primary to secondary windings, a small input voltage is transformed into a very large output voltage
