Ignition Coil
An ignition coil is used in the ignition system of a spark-ignition engine to transform the battery voltage to the much higher voltages required to operate the spark plug(s). The spark plugs then use this burst of high-voltage electricity to ignite the air-fuel mixture. The ignition coil is constructed of two sets of coils wound around an iron core. Older engines often use a single ignition coil which has its output directed to each cylinder by a distributor, a design which is still used by various small engines (such as lawnmower engines). Modern car engines often use a distributor-less system (such as ''coil-on-plug''), whereby every cylinder has its own ignition coil. Diesel engines use compression ignition and therefore do not have ignition coils. Design An ignition coil consists of an iron core surrounded by two coils (''windings'') made from copper wire. The primary winding has relatively few turns of heavy wire, while the secondary winding consists of thousands o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Induction Coil
An induction coil or "spark coil" ( archaically known as an inductorium or Ruhmkorff coil after Heinrich Rühmkorff) is a type of transformer used to produce high-voltage pulses from a low-voltage direct current (DC) supply. p.98 To create the flux changes necessary to induce voltage in the secondary coil, the direct current in the primary coil is repeatedly interrupted by a vibrating mechanical contact called an interrupter. Invented in 1836 by the Irish-Catholic priest Nicholas Callan, also independently by American inventor Charles Grafton Page, the induction coil was the first type of transformer. It was widely used in x-ray machines, spark-gap radio transmitters, arc lighting and quack medical electrotherapy devices from the 1880s to the 1920s. Today its only common use is as the ignition coils in internal combustion engines and in physics education to demonstrate induction. Construction and function An induction coil consists of two coils of insulated wire wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saab 96
The Saab 96 is an automobile manufactured and marketed by Swedish automaker Saab from 1960 to January 1980, replacing the Saab 93. The 96 featured aerodynamic two-door bodywork, four-passenger seating and at first a two-stroke, three-cylinder engine, later a four-stroke V4. Body design Compared with its predecessor, the Saab 93, the 96 featured greater and more easily accessible storage space and a larger rear window. The front end was lengthened for 1965 models, in preparation for a new engine, and the radiator was placed ahead of the engine, rather than above and behind, a leftover from when earlier models had thermosiphon cooling. Both front and rear windows were enlarged slightly for 1968 models. Engine The Saab 96 had a longitudinally mounted engine layout. As first designed, it had an 841 cc displacement, three-cylinder Saab two-stroke engine. By 1965 this was increased to . An optional version of the engine, with triple carburetors and oil injection, was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diode
A diode is a two-Terminal (electronics), terminal electronic component that conducts electric current primarily in One-way traffic, one direction (asymmetric electrical conductance, conductance). It has low (ideally zero) Electrical resistance and conductance, resistance in one direction and high (ideally infinite) resistance in the other. A semiconductor diode, the most commonly used type today, is a Crystallinity, crystalline piece of semiconductor material with a p–n junction connected to two electrical terminals. It has an Exponential function, exponential current–voltage characteristic. Semiconductor diodes were the first Semiconductor device, semiconductor electronic devices. The discovery of asymmetric electrical conduction across the contact between a Crystal, crystalline mineral and a metal was made by German physicist Ferdinand Braun in 1874. Today, most diodes are made of silicon, but other semiconducting materials such as gallium arsenide and germanium are also ...

Flyback Transformer
A flyback transformer (FBT), also called a line output transformer (LOPT), is a special type of electrical transformer. It was initially designed to generate high-voltage sawtooth signals at a relatively high frequency. In modern applications, it is used extensively in switched-mode power supplies for both low (3 V) and high voltage (over 10 kV) supplies. History The flyback transformer circuit was invented as a means of controlling the horizontal movement of the electron beam in a cathode-ray tube (CRT). Unlike conventional transformers, a flyback transformer is not fed with a signal of the same waveshape as the intended output current. A convenient side effect of such a transformer is the considerable energy that is available in its magnetic circuit. This can be exploited using extra windings to provide power to operate other parts of the equipment. In particular, very high voltages are easily obtained using relatively few turns of windings which, after rectifica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flyback Converter
The flyback converter is used in both AC/DC conversion, AC/DC, and DC-DC conversion, DC/DC conversion with galvanic isolation between the input and any outputs. The flyback converter is a buck-boost converter with the inductor split to form a transformer, so that the voltage ratios are multiplied with an additional advantage of isolation. Structure and principle The schematic of a flyback converter is shown in Fig. 1. It is equivalent to that of a buck–boost converter, with the inductor split to form a transformer. Therefore, the operating principle of both converters is very similar: * When the switch is closed (top of Fig. 2), the primary of the transformer is directly connected to the input voltage source. The primary current and magnetic flux in the transformer increases, storing energy in the transformer. The voltage induced in the secondary winding is negative, so the diode is reverse-biased (i.e., blocked). The output capacitor supplies energy to the output load. * Wh ...

Citroën 2CV
The Citroën 2CV (, , lit. "two horses", meaning "two Tax horsepower#France, ''taxable'' horsepower") is an economy car produced by the French company Citroën from 1948 to 1990. Introduced at the 1948 Paris Paris Auto Show, Salon de l'Automobile, it has an air-cooled engine that is front-engine, mounted in the front and front-wheel drive, drives the front wheels. Conceived by Citroën Vice-President Pierre-Jules Boulanger, Pierre Boulanger to help motorise the large number of farmers still using horses and carts in 1930s France, the 2CV has a combination of innovative engineering and straightforward, utilitarian bodywork. The 2CV featured overall low cost of ownership, simplicity of maintenance, an easily serviced air-cooled engine (originally offering ), and minimal fuel consumption. In addition, it had been designed to cross a freshly ploughed field with a basket full of eggs on the passenger's seat without breaking them, because of the great lack of paved roads in France at ...

Wartburg 353
The Wartburg 353, known in some export markets as the Wartburg Knight, is a Mid-size car, medium-sized family car produced by the East Germany, East German car manufacturer Automobilwerk Eisenach, AWE for their Wartburg (marque), Wartburg brand. It was the successor of the Wartburg 311 and was itself succeeded by the Wartburg 1.3. The Wartburg 353 was produced from 1966 to 1988, becoming the Wartburg with the longest production run. During its lifetime, it saw several changes and improvements, the most recognizable of which came in 1985 with a front facelift (as pictured here), a slightly different layout around the engine block, and a new carburettor. Design First introduced in June 1966, the Wartburg 353 was the creation of the former German BMW production facilities (called Automobilwerk Eisenach#After the War: EMW/BMW, EMW under Soviet Union, Soviet occupation). Its origins were ultimately derived from a 1938 DKW design and powered by a two-stroke engine with only seven major ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saab 92
The Saab 92 was the first production car from Saab. The design was very aerodynamic for its time, with a drag coefficient (''cx'' or ''cw'') of 0.30. The entire body was stamped out of one piece of sheet metal and then cut to accommodate doors and windows. Full-scale production started December 12, 1949, based on the prototype Ursaab. All of them were of the Deluxe version. A standard version was advertised, but nobody was interested in buying it so no standard versions were produced. The engine was a transversely-mounted, water-cooled two-cylinder, two-stroke 764 cc displacement, 25 hp (19 kW) engine based on a DKW design, giving a top speed of . The transmission had three gears, the first unsynchronised. In order to overcome the problems of oil starvation during overrun (engine braking) for the two-stroke engine, a freewheel device was fitted. The suspension was by torsion bars. All early Saab 92s were painted in a dark green colour similar to British ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magneto Ignition
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". Design A simple magneto (an electrical generator using permanent magnets) is able to produce relatively low voltage electricity, however it is unable to produce the high voltages required by a spark plug as used in most modern engines (aside from diesel engines). An ''ignition magneto'' also includes an electrical transformer, which converts the electricity to a higher voltage (with the trade-off being a corresponding reduction in the output current). As the points begin to open, point spacing is initially such that the voltage across the primary coil would arc across the points. A capacitor is placed across the points which absorbs the energy stored in the leakage inductance of the primary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epoxy Resin
Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also collectively called ''epoxy''. The IUPAC name for an epoxide group is an oxirane. Epoxy resins may be reacted ( cross-linked) either with themselves through catalytic homo polymerisation, or with a wide range of co-reactants including polyfunctional amines, acids (and acid anhydrides), phenols, alcohols and thiols (sometimes called mercaptans). These co-reactants are often referred to as hardeners or curatives, and the cross-linking reaction is commonly referred to as curing. Reaction of polyepoxides with themselves or with polyfunctional hardeners forms a thermosetting polymer, often with favorable mechanical properties and high thermal and chemical resistance. Epoxy has a wide range of applications, including metal coatings, composi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
