The Duraspark II ignition system is a common upgrade [1] for older Ford cars equipped with a points-type ignition. In most cases, the distributor will interchange with the older-style points distributor. The system is similar to some aftermarket systems [2] and the control module may be easily swapped. Duraspark swaps are easy and can be run by ...
P. R. Mallory and Co Inc was a US producer of dry cell batteries (Mercury; alkaline Duracell), electronic components including electrolytic capacitors, and audible warning devices ("Sonalert"). It also was the parent firm of Mallory Batteries Ltd. , an Irish producer of Ever Ready batteries.
The contact breaker is operated by an engine-driven cam.On an engine with a distributor, the contact breaker can be found beneath the distributor cap.The position of the contact breaker is set so that it opens (and hence generates a spark) at exactly the optimum moment to ignite the fuel/air mixture.
A predecessor system called "Unitized Ignition" was optional on 1972 and 1973 Pontiacs. [citation needed] Most—but not all—HEI systems have the ignition coil mounted in the distributor cap. A control module and magnetic pickup are mounted in the distributor, in place of a conventional ignition system's breaker points and condenser.
The first car to use magneto ignition was the 1901 German Mercedes 35 hp racing car, followed by various cars produced by Benz, Mors, Turcat-Mery, and Nesseldorf. [8] Ignition magnetos were soon used on most cars, for both low voltage systems (which used secondary coils to fire the spark plugs) and high voltage magnetos (which fired the spark ...
Older distributor designs used a cam on the distributor shaft that operates the contact breaker (also called points). Opening the points causes a high induction voltage in the ignition coil. [ 1 ] This design was superseded by an electronically controlled ignition coil with a sensor (usually Hall effect or optical) to control the timing of the ...
An ignition magneto (also called a high-tension magneto) is an older type of ignition system used in spark-ignition engines (such as petrol engines). It uses a magneto and a transformer to make pulses of high voltage for the spark plugs. The older term "high-tension" means "high-voltage".
This sensor is one of the two most important sensors in modern-day engines, together with the camshaft position sensor. As the fuel injection (diesel engines) or spark ignition (petrol engines) is usually timed from the crank sensor position signal, failing sensor will cause an engine not to start or will cut out while running.
