A 25-hour inspection of the No. 4 engine had been performed only nine days prior, but the left magneto had an intermittent short circuit, and the right magneto was producing a weak spark in 8 of the 9 cylinders due to wear of the compensator cam. The NTSB said the problems with the No. 4 engine magnetos likely caused a loss of engine power that ...
Magneto components. Impulse coupling components. 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". [1]
Pressure in cylinder pattern in dependence on ignition timing: (a) - misfire, (b) too soon, (c) optimal, (d) too late. In a spark ignition internal combustion engine, ignition timing is the timing, relative to the current piston position and crankshaft angle, of the release of a spark in the combustion chamber near the end of the compression stroke.
Demonstration hand-cranked magneto made circa 1925, on display at the Musée d'histoire des sciences de la Ville de Genève. 2kW Société de l'Alliance magneto generator for arc lamps, of around 1870. A magneto is an electrical generator that uses permanent magnets to produce periodic pulses of alternating current.
Points bounce is a feature of a points-triggered system. In the standard system with points, distributor, ignition coil, ignition (Kettering system) points bounce prevents the coil from saturating fully as RPM increases resulting in a weak spark, thus limiting high speed potential. In a CD ignition, at least those early attempts, the points ...
A trembler coil, around 1915. The mechanism on the end is the "trembler" or interrupter. [1]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]
The VRDK's designer was summoned in an attempt to solve its problems although not all of these were design issues. The first prototype was grounded for most of June to remedy magneto problems and to add extra air intakes to cool the spark plugs. It attained a speed of 820 km/h (510 mph) at 6,700 m (21,982 ft) on 3 July.
When a spark plug is used, the spark was generated by either a magneto or else a trembler (or "buzz") coil. A buzz coil uses battery power to generate a series of high voltage pulses that are fed to the spark plug. For igniter ignition, either a battery and coil is used or a "low-tension" magneto is used. With battery and coil ignition, a ...
