ignition distributor
21high energy ignition system with electronic spark timing — (HEI EST) A system consists of an electronic distributor, with the ignition coil mounted on the distributor cap on 6 and 8 cylinder models or externally on 4 cylinder models; the ignition timing is performed electronically by the electronic… …
22pressurized ignition — A type of ignition system for high altitude operation of reciprocating engines. To prevent high voltage inside an unpressurized distributor from jumping to the wrong electrode or to ground because of low air pressure at high altitudes, the… …
23conventional ignition system — An ignition system consisting of the battery, ignition switch, ballast resistor, ignition coil, distributor, contact breaker points, condenser, centrifugal or vacuum advance unit, spark plugs, and high tension wires …
24direct ignition system — (DIS) An ignition system which does not used a distributor but carries high voltage from the ignition coils directly to the spark plugs. Also see integrated Direct Ignition System …
25distributorless ignition system — (DIS or DLS) An electronic ignition system that does not have a conventional rotating distributor. Instead, it uses multi spark ignition coils or one ignition coil for each spark plug …
26map-controlled ignition — A microprocessor controlled ignition system with electronic ignition timing by means of an ignition map stored in the control unit memory. The engine speed is sensed by Hall generators at the distributor or magnetic pick ups on the crankshaft,… …
27mapped ignition — A microprocessor controlled ignition system with electronic ignition timing by means of an ignition map stored in the control unit memory. The engine speed is sensed by Hall generators at the distributor or magnetic pick ups on the crankshaft,… …
28single-spark ignition coil — In a distributorless ignition system with an odd number of cylinders, each cylinder requires its own ignition coil; distributor logic on the low voltage side performs the voltage distribution to each coil. Also see multi spark ignition coil …
29breaker-triggered transistorized ignition — A transistorized ignition system whose distributor is the same as that of a coil ignition system, but whose contact breaker switches only the control current of the transistor, not the primary current. Usually not fitted as original equipment …
30magneto ignition — A compact assembly of a magneto generator, an ignition coil, and a distributor. Ignition voltage is induced within the magneto by the movement of a coil relative to the poles of a permanent magnet. Because it needs no battery, the system is… …
