Sleeve Valve
The sleeve valve is a type of valve mechanism for piston engines, distinct from the usual poppet valve. Sleeve valve engines saw use in a number of pre-World War II luxury cars and in the United States in the Willys-Knight car and light truck. They subsequently fell from use due to advances in poppet-valve technology, including sodium cooling, and the Knight system double sleeve engine's tendency to burn a lot of lubricating oil or to seize due to lack of it. The Scottish Argyll company used its own, much simpler and more efficient, single sleeve system (Burt-McCollum) in its cars, a system which, after extensive development, saw substantial use in British aircraft engines of the 1940s, such as the Napier Sabre, Bristol Hercules, Centaurus, and the promising but never mass-produced Rolls-Royce Crecy, only to be supplanted by the jet engines. Description A sleeve valve takes the form of one or more machined sleeves. It fits between the piston and the cylinder wall in the cylin ...

Sleeve Valve Closeup
A sleeve ( ang, slīef, a word allied to ''slip'', cf. Dutch ) is the part of a garment that covers the arm, or through which the arm passes or slips. The sleeve is a characteristic of fashion seen in almost every country and time period, across a myriad of styles of dress. Styles vary from close-fitting to the arm, to relatively unfitted and wide sleeves, some with extremely wide cuffs. Long, hanging sleeves have been used variously as a type of pocket, from which the phrase "to have up one's sleeve" (to have something concealed ready to produce) comes. There are many other proverbial and metaphorical expressions associated with the sleeve, such as "to wear one's heart upon one's sleeve", and "to laugh in one's sleeve". Early Western medieval sleeves were cut straight, and underarm triangle-shaped gussets were used to provide ease of movement. In the 14th century, the rounded sleeve cap was invented, allowing a more fitted sleeve to be inserted, with ease around the sleeve he ...

Bristol Engine Company
The Bristol Aeroplane Company, originally the British and Colonial Aeroplane Company, was both one of the first and one of the most important British aviation companies, designing and manufacturing both airframes and aircraft engines. Notable aircraft produced by the company include the 'Boxkite', the Bristol Fighter, the Bulldog, the Blenheim, the Beaufighter, and the Britannia, and much of the preliminary work which led to Concorde was carried out by the company. In 1956 its major operations were split into Bristol Aircraft and Bristol Aero Engines. In 1959, Bristol Aircraft merged with several major British aircraft companies to form the British Aircraft Corporation (BAC) and Bristol Aero Engines merged with Armstrong Siddeley to form Bristol Siddeley. BAC went on to become a founding component of the nationalised British Aerospace, now BAE Systems. Bristol Siddeley was purchased by Rolls-Royce in 1966, who continued to develop and market Bristol-designed engines. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Argyll (car)
Argyll was a Scottish motor car marque manufactured from 1899 to 1932, and again from 1976 to around 1990. The original Argyll marque Alex Govan founded The Hozier Engineering Company in 1899, and it was at this factory that the first ''Argyll Voiturette'' was produced; copied from the contemporary Renault, it featured a 2¾ hp de Dion engine and shaft-drive. 1901 models had an upgraded engine of 5 hp; cars made in 1902 were upgraded even further, using 8 hp units. Soon there appeared a 10 hp twin with radiator tubes forming the sides of the hood; in 1904 the company introduced a range of Aster-engined cars with front-mounted radiators. One of these was a 10 hp of 1985 cc; others were fours of 3054 cc, 3686 cc, and 4849 cc. All cars featured Govan's rather awkward gearbox, which had a T-shaped gate and separate reverse and change-speed levers. The company, by now named Argyll Motors Ltd. had now become Scotland's biggest marque and soon moved from its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Argyll Single Sleeve-valve Engine (Autocar Handbook, Ninth Edition)
Argyll (; archaically Argyle, in modern Gaelic, ), sometimes called Argyllshire, is a historic county and registration county of western Scotland. Argyll is of ancient origin, and corresponds to most of the part of the ancient kingdom of on Great Britain. Argyll was also a medieval bishopric with its cathedral at Lismore, as well as an early modern earldom and dukedom, the Dukedom of Argyll. It borders Inverness-shire to the north, Perthshire and Dunbartonshire to the east, and—separated by the Firth of Clyde—neighbours Renfrewshire and Ayrshire to the south-east, and Buteshire to the south. Between 1890 and 1975, Argyll was an administrative county with a county council. Its area corresponds with most of the modern council area of Argyll and Bute, excluding the Isle of Bute and the Helensburgh area, but including the Morvern and Ardnamurchan areas of the Highland council area.

Autocar (magazine)
''Autocar'' (originally ''The Autocar'') is a weekly British automobile magazine published by the Haymarket Media Group. It was first published in 1895 and refers to itself as "the world's oldest car magazine". There are now several international editions, including for China, India, New Zealand, and South Africa. History The publication was launched as ''The Autocar'' by Iliffe and Son Ltd. "in the interests of the mechanically propelled road carriage" on 2 November 1895 when, it is believed, there were only six or seven cars in the United Kingdom. L. J. K. Setright suggests that the magazine was set up by Henry Sturmey as an organ of propaganda for Harry J. Lawson, founder of the Daimler Company and a journalist on the magazine in its early days. Henry Sturmey stood down as editor of ''The Autocar'' magazine and left the company in 1901. ''Autocar'' claims to have invented the road test in 1928 when it analysed the Austin 7 Gordon England Sunshine Saloon. '' ...

Mors (automobile)
The Mors automobile factory was an early French car manufacturer. It was one of the first to take part in automobile racing, beginning in 1897, due to the belief of the company founder, Émile Mors, in racing's technical and promotional benefits. By the turn of the century, automobile racing had become largely a contest between Mors and Panhard et Levassor. Technical achievements Mors was one of the first automobiles to use the V engine configuration. The Mors 60 horsepower Grand Prix car was powered by a 9.2-litre V4 side valve engine, with magneto ignition and dry sump lubrication, which could reach 950 rpm. The car had a steel chassis and a four-speed transmission that drove the rear wheels via chain drive, and rear-wheel brakes. In 1902, Mors added pneumatic shock absorbers to their cars, which represented a great leap forward given the quality of the roads and racetracks at the time. With this car, Henri Fournier was able to win the highly significant Paris-Berli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avions Voisin
Avions Voisin was a French luxury automobile brand established by Gabriel Voisin in 1919 which traded until 1939. History Gabriel B. Voisin was an aviation pioneer and manufacturer who in 1919 started producing cars using Knight-type sleeve valve engines at Issy-les-Moulineaux, an industrial suburb to the southwest of Paris. Former student of the Fine Arts School of Lyon and enthusiast for all things mechanical since his childhood, Voisin's uncompromisingly individual designs made extensive use of light alloys, especially aluminum. One of the company's most striking early designs was the '' Voisin Laboratoire'' Grand Prix car of 1923; one of the first cars ever to use monocoque chassis construction, and utilising small radiator-mounted propeller to drive the cooling pump. The characteristic Voisin style of 'rational' coachwork he developed in conjunction with his collaborator André Noel. Noel prioritized lightness, central weight distribution, capacious luggage boxes an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peugeot
Peugeot (, , ) is a French brand of automobiles owned by Stellantis. The family business that preceded the current Peugeot companies was founded in 1810, with a steel foundry that soon started making hand tools and kitchen equipment, and then bicycles. On 20 November 1858, Émile Peugeot applied for the lion trademark. Armand Peugeot (1849–1915) built the company's first car steam tricycle, in collaboration with Léon Serpollet in 1889; this was followed in 1890 by an internal combustion car with a Panhard- Daimler engine. The Peugeot company and family are originally from Sochaux. Peugeot retains a large manufacturing plant and Peugeot museum there. In February 2014, the shareholders agreed to a recapitalisation plan for the PSA Group, in which Dongfeng Motors and the French government each bought a 14% stake in the company. Peugeot has received many international awards for its vehicles, including six European Car of the Year awards. Peugeot has been involved suc ...

Panhard
Panhard was a French motor vehicle manufacturer that began as one of the first makers of automobiles. It was a manufacturer of light tactical and military vehicles. Its final incarnation, now owned by Renault Trucks Defense, was formed by the acquisition of Panhard by Auverland in 2005, and then by Renault in 2012. In 2018 Renault Trucks Defense, ACMAT and Panhard combined under a single brand, Arquus. History Panhard was originally called Panhard et Levassor, and was established as an automobile manufacturing concern by René Panhard and Émile Levassor in 1887. Early years Panhard et Levassor sold their first automobile in 1890, based on a Daimler engine license. Levassor obtained his licence from Paris lawyer Edouard Sarazin, a friend and representative of Gottlieb Daimler's interests in France. Following Sarazin's 1887 death, Daimler commissioned Sarazin's widow Louise to carry on her late husband's agency. The Panhard et Levassor license was finalised by Louise ...
