Ignition System
Ignition systems are used by heat engines to initiate combustion by igniting the fuel-air mixture. In a spark ignition versions of the internal combustion engine (such as petrol engines), the ignition system creates a spark to ignite the fuel-air mixture just before each ''combustion'' stroke. Gas turbine engines and rocket engines normally use an ignition system only during start-up. Diesel engines use ''compression ignition'' to ignite the fuel-air mixture using the heat of compression and therefore do not use an ignition system. They usually have glowplugs that preheat the combustion chamber to aid starting in cold weather. Early cars used ignition magneto and trembler coil systems, which were superseded by Distributor-based systems (first used in 1912). Electronic ignition systems (first used in 1968) became common towards the end of the 20th century, with coil-on-plug versions of these systems becoming widespread since the 1990s.

Coil-on-plug Ignition
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 of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battery (electricity)
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. The terminal marked negative is the source of electrons. When a battery is connected to an external electric load, those negatively charged electrons flow through the circuit and reach the positive terminal, thus causing a redox reaction by attracting positively charged ions, or cations. Thus, higher energy reactants are converted to lower energy products, and the free-energy difference is delivered to the external circuit as electrical energy. Historically the term "battery" specifically referred to a device composed of multiple cells; however, the usage has evolved to include devices composed of a single cell. Primary (single-use or "disposable") batteries are used once and discarded, as the electrode mat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coventry Climax
Coventry Climax was a British manufacturer of forklift trucks, fire pumps, racing engines, and other speciality engines. History Pre WWI The company was started in 1903 as Lee Stroyer, a joint venture by Jens Stroyer and Pelham Lee. In 1905, following the departure of Stroyer, it was relocated to Paynes Lane, Coventry, and renamed as Coventry Simplex by Horace Pelham Lee, a former Daimler employee, who saw an opportunity in the nascent internal combustion engine market. An early user was GWK, who produced over 1,000 light cars with Coventry-Simplex two-cylinder engines between 1911 and 1915. Just before the First World War, a Coventry-Simplex engine was used by Lionel Martin to power the first Aston Martin car. Ernest Shackleton selected Coventry-Simplex to power the tractors that were to be used in his Imperial Trans-Antarctic Expedition of 1914. Hundreds of Coventry-Simplex engines were manufactured during the First World War to be used in generator sets for se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Racing Motors
British Racing Motors (BRM) was a British Formula One motor racing team. Founded in 1945 and based in the market town of Bourne, Lincolnshire, Bourne in Lincolnshire, it participated from 1951 to 1977, competing in 197 Grand Prix motor racing, grands prix and winning seventeen. BRM won the constructors' title in 1962 when its driver Graham Hill became world champion. In 1963, 1964, 1965 and 1971, BRM came second in the constructors' competition. History BRM was founded just after the World War II, Second World War by Raymond Mays, who had built several Hillclimbing, hillclimb and road racing cars under the English Racing Automobiles, ERA brand before the war, and Peter Berthon, a long-time associate. Mays' pre-war successes (and access to pre-war Mercedes-Benz and Auto Union design documents) inspired him to build an all-British grand prix car for the post-war era as a national prestige project, with financial and industrial backing from the British motor industry and its su ...

Transistor
A transistor is a semiconductor device used to Electronic amplifier, amplify or electronic switch, switch electrical signals and electric power, power. It is one of the basic building blocks of modern electronics. It is composed of semiconductor material, usually with at least three terminal (electronics), terminals for connection to an electronic circuit. A voltage or Electric current, current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Some transistors are packaged individually, but many more in miniature form are found embedded in integrated circuits. Because transistors are the key active components in practically all modern electronics, many people consider them one of the 20th century's greatest inventions. Physicist Julius Edgar Lilienfeld proposed the concept of a field-effect transisto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cold Cathode
A cold cathode is a cathode that is not electrically heated by a Electrical filament, filament.A negatively charged electrode emits electrons or is the positively charged terminal. For more, see field emission. A cathode may be considered "cold" if it emits more electrons than can be supplied by thermionic emission alone. It is used in Gas discharge lamp, gas-discharge lamps, such as neon lamps, discharge tubes, and some types of vacuum tube. The other type of cathode is a hot cathode, which is heated by electric current passing through a Electrical filament, filament. A cold cathode does not necessarily operate at a low temperature: it is often heated to its operating temperature by other methods, such as the current passing from the cathode into the gas. Cold-cathode devices A cold-cathode vacuum tube does not rely on external heating of an electrode to provide thermionic emission of electrons. Early cold-cathode devices included the Geissler tube and Julius Plücker, Plucker ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distributor
A distributor is an electric and mechanical device used in the ignition system of older spark-ignition engines. The distributor's main function is to route electricity from the ignition coil to each spark plug at the correct time. Design A distributor consists of a rotating arm ('rotor') that is attached to the top of a rotating 'distributor shaft'. The rotor constantly receives high-voltage electricity from an ignition coil via brushes at the centre of the rotor. As the rotor spins, its tip passes close to (but does not touch) the output contacts for each cylinder. As the electrified tip passes each output contact, the high-voltage electricity is able to 'jump' across the small gap. This burst of electricity then travels to the spark plug (via high tension leads), where it ignites the air-fuel mixture in the combustion chamber. On most overhead valve engines, the distributor shaft is driven by a gear on the camshaft, often shared with the oil pump; on most overh ...

Capacitor
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the '' condenser microphone''. It is a passive electronic component with two terminals. The utility of a capacitor depends on its capacitance. While some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component designed specifically to add capacitance to some part of the circuit. The physical form and construction of practical capacitors vary widely and many types of capacitor are in common use. Most capacitors contain at least two electrical conductors, often in the form of metallic plates or surfaces separated by a dielectric medium. A conductor may be a foil, thin film, sintered bead of metal, or an electrolyte. The nonconductin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
