Spark Plug
A spark plug (sometimes, in British English, a sparking plug, and, colloquially, a plug) is a device for delivering electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark, while containing combustion pressure within the engine. A spark plug has a metal threaded shell, electrically isolated from a central electrode by a ceramic insulator. The central electrode, which may contain a resistor, is connected by a heavily insulated wire to the output terminal of an ignition coil or magneto. The spark plug's metal shell is screwed into the engine's cylinder head and thus electrically grounded. The central electrode protrudes through the porcelain insulator into the combustion chamber, forming one or more spark gaps between the inner end of the central electrode and usually one or more protuberances or structures attached to the inner end of the threaded shell and designated the ''si ...

Spark Gap
A spark gap consists of an arrangement of two Conductor (material), conducting electrodes separated by a gap usually filled with a gas such as air, designed to allow an electric spark to pass between the conductors. When the potential difference between the conductors exceeds the breakdown voltage of the gas within the gap, a electric spark, spark forms, Ionization, ionizing the gas and drastically reducing its electrical resistance. An electric current then flows until the path of ionized gas is broken or the current reduces below a minimum value called the "holding current". This usually happens when the voltage drops, but in some cases occurs when the heated gas rises, stretching out and then breaking the wiktionary:filament, filament of ionized gas. Usually, the action of ionizing the gas is violent and disruptive, often leading to sound (ranging from a ''snap'' for a spark plug to thunder for a lightning discharge), light, and heat. Spark gaps were used historically in e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Guinness Family
The Guinness family is an extensive Irish family known for its achievements in brewing, banking, politics, and religious ministry. The brewing branch is particularly well known among the general public for producing the dry stout beer Guinness, as founded by Arthur Guinness in 1759. An Anglo-Irish Protestant family, beginning in the late 18th century, they became a part of what is known in Ireland as the Protestant Ascendancy. The "banking line" Guinnesses all descend from Arthur's brother Samuel (1727–1795) who set up as a goldbeater in Dublin in 1750; his son Richard (1755–1830), a Dublin barrister; and Richard's son Robert Rundell Guinness who founded Guinness Mahon in 1836. The current head of the family is the Earl of Iveagh. Another prominent branch, descended from the 1st Earl of Iveagh, is headed by Lord Moyne. Origins The Guinness family refers to the descendants of Richard Guinness (born ) of Celbridge, who married Elizabeth Read (1698–1742), the ...

Kenelm Lee Guinness
Kenelm Edward Lee Guinness MBE (14 August 1887 – 10 April 1937) was a British racing driver of the 1910s and 1920s mostly associated with Sunbeam racing cars. He set a new Land Speed Record in 1922. Also an automotive engineer, he invented and manufactured the KLG spark plug. Additionally, aside from motorsport and mechanical interests, he was a director of the Guinness brewing company. Early life Guinness was born on 14 August 1887 in London. Known as 'Bill' to friends, he was a member of the prominent Irish Guinness family as a grandson of Sir Benjamin Guinness, and would later be a director of the brewing company. He was educated at Cambridge University, where his interests in motor racing first developed as a mechanic to his elder brother Sir Algernon Guinness. Career Beginnings in motor racing His first major race as a driver was the 1907 Isle of Man Tourist Trophy. His Darracq retired early, owing to axle failure. This involvement with the closely related S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oliver Lodge
Sir Oliver Joseph Lodge (12 June 1851 – 22 August 1940) was an English physicist whose investigations into electromagnetic radiation contributed to the development of Radio, radio communication. He identified electromagnetic radiation independent of Heinrich Rudolf Hertz, Heinrich Hertz's proof. At his 1894 Royal Institution lectures ("''The Work of Hertz and Some of His Successors''"), Lodge's demonstrations on methods to transmit and detect radio waves included an improved early radio receiver he named the "coherer". His work led to him holding key patents in early radio communication, his "syntonic" (or tuning) patents. Lodge was appointed the assistant professor of applied mathematics at Bedford College, London in 1879, became the chair of physics at the University of Liverpool, University College Liverpool in 1881, and was the principal of the University of Birmingham from 1900 to 1919. Lodge was also pioneer of Spiritualism (movement), spiritualism. His pseudoscientifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Albert Champion (cyclist)
Albert Champion (5 April 1878 – 26 October 1927) was a French track bicycle racer and later an industrialist who won the 1899 Paris–Roubaix. In 1905 he incorporated the Albert Champion Company in Boston to make porcelain spark plugs with his name on them. Three years later founded the Champion Ignition Company in Flint, Michigan. In 1922 he changed the name to AC Spark Plug Company, after his initials, to settle out of court with his original partners in the Albert Champion Company. The company is now known as ACDelco and is owned by General Motors. Cycling Champion was a racing cyclist at the end of the 19th century. His win in Paris–Roubaix came as a surprise because he had been known as a velodrome rider. After Champion won Paris-Roubaix he received a contract from a bicycle manufacturer in Boston to race in America for the 1900 season. The offer coincided with Champion's receiving orders to report for compulsory conscription, which could have meant up to seven years ...

Gottlob Honold
220px, Gottlob Honold 1910 Gottlob Honold (26 August 1876 – 17 March 1923) was a leading engineer in the workshop of Robert Bosch, where he invented a practical ignition magneto, practical automobile headlights, and a practical vehicle horn. Honold was born on 26 August 1876 in Langenau, in Germany, about 10 miles northeast of Ulm. Honold's father was a friend of the father of Robert Bosch. In 1891, Honold first worked in Bosch's Stuttgart workshop as an apprentice. Honold then studied engineering at the Technical University of Stuttgart. In 1901, Honold accepted an offer to work for Bosch once again, where he specialized on ignition. His task was to build an apparatus "that would produce a ''hot'' spark of relatively ''long'' duration (arc) with nonmoving electrodes." By December, collaborating with Arnold Zähringer, Honold had a test model using a common power source for the low and high voltages in a single unit. Honold also helped develop the automotive headlights tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
