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 ...
These effects can largely be overcome using electronic ignition systems, where the contact breakers are retrofitted by a magnetic (Hall effect) or optical sensor device. However, because of their simplicity, and since contact breaker points gradually degrade instead of catastrophically failing, they are still used on aircraft engines.
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 [ 1 ] This design was superseded by an electronically controlled ignition coil with a sensor (usually Hall effect or optical) to control the timing of the ...
For Dummies is an extensive series of instructional reference books which are intended to present non-intimidating guides for readers new to the various topics covered. The series has been a worldwide success with editions in numerous languages.
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 ...
As batteries became more common in cars (due to the increased usage of electric starter motors), magneto systems were replaced by systems using an induction coil.The 1886 Benz Patent-Motorwagen and the 1908 Ford Model T used a trembler coil ignition system, whereby the trembler interrupted the current through the coil and caused a rapid series of sparks during each firing.
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.
Mallory metal is proprietary name [1] for an alloy of tungsten, with other metallic elements added to improve machining.. Its primary use is as a balance weight which is added to the crankshaft of an automotive engine, where the existing counterweight is not large enough to compensate for the weight of the reciprocating and rotating components attached to the crankshaft's connecting rod journals.
