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 ...
Unlike a dynamo, a magneto does not contain a commutator to produce direct current. It is categorized as a form of alternator, although it is usually considered distinct from most other alternators, which use field coils rather than permanent magnets. Hand-cranked magneto generators were used to provide ringing current in telephone systems.
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.
The ignition coils for these can be combined into a single casing (a coil pack) and located away from the spark plugs; however it is increasingly common for coil-on-plug systems to be used, whereby the individual ignition coils are small units attached directly to the top of each spark plug. An advantage of coil-on-plug systems is that in the ...
A trembler coil, buzz coil or vibrator coil is a type of high-voltage ignition coil used in the ignition system of early automobiles, most notably the Benz Patent-Motorwagen and the Ford Model T. [2] Its distinguishing feature is a vibrating magnetically-activated contact called a trembler or interrupter , [ 3 ] [ 1 ] which breaks the primary ...
Not all small engine ignition systems are CDI. Some engines like older Briggs and Stratton use magneto ignition. The entire ignition system, coil and points, are under the magnetized flywheel. Another sort of ignition system commonly used on small off-road motorcycles in the 1960s and 1970s was called Energy Transfer.
