Clive Gallop
Colonel Reginald Clive Gallop (4 February 1892 – 7 September 1960 Martin Pugh, 'Bentley Boys (act. 1919–1931)’, ''Oxford Dictionary of National Biography'', Oxford University Press, May 2013) was a British engineer, racing driver and First World War pilot. He was one of the team which developed their first engine for Bentley Motors. Royal Flying Corps Clive Gallop joined the Royal Flying Corps, flying aeroplanes over the Western Front. He commanded a number of flights, including No. 56 Squadron. London racing driver, motor vehicle dealer and engineer W. O. Bentley had suggested aluminium pistons to his car supplier Doriot, Flandrin & Parant and had them installed in those cars he imported. Following commissioning on the outbreak of war as an engineer by the Royal Naval Air Service Bentley was sent to Gwynnes pumps workshops in Chiswick which were making French Clerget engines under license. Part of Bentley's duties was to liaise between the squadrons in the field i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1922 French Grand Prix
The 1922 French Grand Prix (formally the XVI French Grand Prix, Grand Prix de l'Automobile Club de France) was a Grand Prix motor racing, Grand Prix motor race held at Strasbourg on 15 July 1922. The race was run over 60 laps of the 13.38km circuit for a total distance of just over 800km and was won by Felice Nazzaro driving a Fiat. This race is notable as the first Grand Prix to feature a massed start. The race was run to new Grand Prix regulations, requiring engines no larger than 2 litres, in cars with two seats and weighing at least 650kg. In practice, the Fiats were dominant, with only the Bugatti drivers close in times (the Bugatti drivers had the advantage of the Bugatti factory being in nearby Molsheim, so had already learned the circuit). After the rolling start, Felice Nazzaro lead Ernest Friderich, Friderich at the end of the first lap, with the other Fiat drivers down in the pack due to their lower starting positions. By lap 4, Pietro Bordino, Bordino had taken the lead ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coventry
Coventry ( or rarely ) is a City status in the United Kingdom, cathedral city and metropolitan borough in the West Midlands (county), West Midlands county, in England, on the River Sherbourne. Coventry had been a large settlement for centuries. Founded in the early Middle Ages, its city status was formally recognised in a charter of 1345. The city is governed by Coventry City Council, and the West Midlands Combined Authority. Historic counties of England, Formerly part of Warwickshire until 1451, and again from 1842 to 1974, Coventry had a population of 345,324 at the 2021 census, making it the tenth largest city in England and the 13th largest in the United Kingdom. It is the second largest city in the West Midlands (region), West Midlands region, after Birmingham, from which it is separated by an area of Green belt (United Kingdom), green belt known as the Meriden Gap; it is the third largest in the wider Midlands after Birmingham and Leicester. The city is part of a larger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carburetor
A carburetor (also spelled carburettor or carburetter) is a device used by a gasoline internal combustion engine to control and mix air and fuel entering the engine. The primary method of adding fuel to the intake air is through the Venturi effect or Bernoulli's principle or with a Pitot tube in the main metering circuit, though various other components are also used to provide extra fuel or air in specific circumstances. Since the 1990s, carburetors have been largely replaced by fuel injection for cars and trucks, but carburetors are still used by some small engines (e.g. lawnmowers, generators, and concrete mixers) and motorcycles. In addition, they are still widely used on piston-engine–driven aircraft. Diesel engines have always used fuel injection instead of carburetors, as the compression-based combustion of diesel requires the greater precision and pressure of fuel injection. Etymology The term ''carburetor'' is derived from the verb ''carburet'', which means "to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pent-roof Combustion Chamber
In engine design, the penta engine (or penta head) is an arrangement of the upper portion of the cylinder and valves that is common in engines using four valves per cylinder. Design Among the advantages is a faster burn time of the air-fuel mix. It is similar in concept to the hemi engine, both in design and purpose, but a hemispherical cylinder head is limited to only two valves without the use of a more complex sub-rocker assembly. The four-valve penta engine design was invented by Peugeot Peugeot (, , ) is a French automobile brand owned by Stellantis. The family business that preceded the current Peugeot companies was established in 1810, making it the oldest car company in the world. On 20 November 1858, Émile Peugeot applie ... of France, to be first used in the 1911 Indianapolis 500 race. The penta engine (also termed pentroof combustion chamber) is the most common design used today by many manufacturers for four-valve-per-cylinder engines producing relativel ...

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 ...

Overhead Camshaft
An overhead camshaft (OHC) engine is a piston engine in which the camshaft is located in the cylinder head above the combustion chamber. This contrasts with earlier overhead valve engines (OHV), where the camshaft is located below the combustion chamber in the engine block. ''Single overhead camshaft'' (SOHC) engines have one camshaft per cylinder bank, bank of cylinders. ''Dual overhead camshaft'' (DOHC, also known as "twin-cam") engines have two camshafts per bank. The first production car to use a DOHC engine was built in 1910. Use of DOHC engines slowly increased from the 1940s, leading to many automobiles by the early 2000s using DOHC engines. Design In an OHC engine, the camshaft is located at the top of the engine, above the combustion chamber. This contrasts the earlier overhead valve engine (OHV) and flathead engine configurations, where the camshaft is located down in the engine block. The valves in both OHC and OHV engines are located above the combustion chamber; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multi-valve
A multi-valve or multivalve Four-stroke engine, four-stroke internal combustion engine is one where each Cylinder (engine), cylinder has ''more than two'' poppet valve, valves – more than the minimum required of one of each, for the purposes of air and fuel intake, and Exhaust system, venting exhaust gases. Multi-valve engines were conceived to improve one or both of these, often called "better breathing", and with the added benefit of more valves that are smaller, thus having less mass in motion (per individual valve and spring), may also be able to operate at higher revolutions per minute (RPM) than a two-valve engine, delivering even more intake an/or exhaust per unit of time, thus potentially more power (physics), power. Multi-valve rationale Multi-valve engine design A multi-valve engine design has three, four, or five poppet valves per cylinder, to achieve greater performance. In automotive engineering, any four-stroke internal combustion engine needs at least two v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bugatti
Automobiles Ettore Bugatti was a German then French automotive industry, manufacturer of high performance vehicle, high-performance automobiles. The company was founded in 1909 in the then-German Empire, German city of Molsheim, Alsace, by the Italian-born industrial designer Ettore Bugatti. The cars were known for their design beauty and numerous race victories. Famous Bugatti automobiles include the Bugatti Type 35, Type 35 Grand Prix cars, the Bugatti Royale, Type 41 "Royale", the Bugatti Type 57, Type 57 "Atlantic" and the Bugatti Type 55, Type 55 sports car. The death of Ettore Bugatti in 1947 proved to be a severe blow to the marque, and the death of his son Jean Bugatti, Jean in 1939 meant that there was no successor to lead the factory. With no more than about 8,000 cars made, the company struggled financially, and it released one last model in the 1950s before eventually being purchased for its airplane parts business in 1963. In 1987, an Italian entrepreneur bought th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Straight-4
A straight-four engine (also referred to as an inline-four engine) is a four-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. The majority of automotive four-cylinder engines use a straight-four layout (with the exceptions of the flat-four engines produced by Subaru and Porsche) and the layout is also very common in motorcycles and other machinery. Therefore the term "four-cylinder engine" is usually synonymous with straight-four engines. When a straight-four engine is installed at an inclined angle (instead of with the cylinders oriented vertically), it is sometimes called a slant-four. Between 2005 and 2008, the proportion of new vehicles sold in the United States with four-cylinder engines rose from 30% to 47%. By the 2020 model year, the share for light-duty vehicles had risen to 59%. Design A four-stroke straight-four engine always has a cylinder on its power stroke, unlike engines with fewer cylinders where there is no power st ...

W O Bentley
Walter Owen Bentley, (16 September 1888 – 13 August 1971) was an English engineer who founded Bentley in London. He was a motorcycle and car racer as a young man. After making a name for himself as a designer of aircraft and automobile engines, Bentley established his own firm in 1919. He built the firm into one of the world's premier luxury and performance auto manufacturers, and led the marque to multiple victories at the 24 Hours of Le Mans. After selling his namesake company to Rolls-Royce in 1931, he was employed as a designer for Lagonda, Aston Martin and Armstrong Siddeley. Early life Bentley was born on 16 September 1888, in Hampstead, London. He was the youngest of nine children. His father Alfred Bentley was a retired businessman and his mother Emily (née Waterhouse), daughter of T. G. Waterhouse, was born in Adelaide, Australia.H. G.

Cricklewood
Cricklewood is a town in North London, England, in the London Boroughs of Camden, Barnet, and Brent. The Crown pub, now the Clayton Crown Hotel, is a local landmark and lies north-west of Charing Cross. Cricklewood was a small rural hamlet around Edgware Road, the Roman road which was later called Watling Street and which forms the boundary of the two boroughs that share Cricklewood. The area urbanised after the arrival of the surface and underground railways in nearby Willesden Green in the 1870s. The shops on Cricklewood Broadway, as Edgware Road is known here, contrast with quieter surrounding streets of largely late-Victorian, Edwardian, and 1930s housing. The area has strong links with Ireland due to a sizeable Irish population. The Gladstone Park lies on the area's western periphery. Cricklewood has two conservation areas, the Mapesbury Estate and the Cricklewood Railway Terraces, and in 2012 was awarded £1.65 million from the Mayor of London's office to improve ...
