Group 6 (racing)
Group 6 was the official designation applied by the FIA to two motor racing classifications, the Prototype-Sports Car category from 1966 to 1971 and the Two-Seater Racing Cars class from 1976 to 1982. Group 6 Prototype-Sports Cars (1966 to 1971) The original Group 6 was introduced for the 1966 racing season, at the same time as a new Group 4 Sports Car category. Whilst Group 4 specified that competing cars must be one of at least fifty examples built, Group 6 had no minimum production requirement. Nor did it have a maximum engine capacity limit although there were weight, dimensional and other restrictions placed on the Group 6 cars.M.L Twite, The World’s Racing Cars, 4th Edition, 1970, Page 136 The Prototypes and Sports Cars categories each had their own international championships to fight for but many of the major international endurance races such as the 24 Hours of Le Mans would count as qualifying rounds for both championships. 1968 saw a three-litre engine capacity li ...

Naturally-aspirated Engine
A naturally aspirated engine, also known as a normally aspirated engine, and abbreviated to N/A or NA, is an internal combustion engine in which air intake depends solely on atmospheric pressure and does not have forced induction through a turbocharger or a supercharger. Description In a naturally aspirated engine, air for combustion (Diesel cycle in a diesel engine or specific types of Otto cycle in petrol engines, namely petrol direct injection) or an air/fuel mixture (traditional Otto cycle petrol engines), is drawn into the engine's cylinders by atmospheric pressure acting against a partial vacuum that occurs as the piston travels downwards toward bottom dead centre during the intake stroke. Owing to innate restriction in the engine's inlet tract, which includes the intake manifold, a small pressure drop occurs as air is drawn in, resulting in a volumetric efficiency of less than 100 percent—and a less than complete air charge in the cylinder. The density of the ai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sports Prototypes
A sports prototype, sometimes referred to simply as a prototype, is a type of race car that is used in high-level categories of sports car racing. They are purpose-built auto-sports race cars, as opposed to production-car based or street-legal, low-volume homologation specials – thus entirely not intended for consumer purchase, or production beyond the fabrication of the (nearly) unique cars entered into races and in race-car competition classes or "formulas", with sufficiently open regulations to allow for vehicles of unique design to partake. Prototype racing cars have competed in sports car racing since before World War II, but became the top echelon of sports cars in the 1960s as they began to replace homologated sports cars. Current ACO regulations allow most sports car series to use two forms of cars: ''grand tourers (GT cars)'', which are strictly based on production street cars, and ''sports prototypes'', which are allowed a great amount of flexibility within set ru ...

Chevron B16
The Chevron B16 was a Group 4 (racing), Group 4 sports prototype race car, designed, developed, and built in 1969 by the British racing car manufacturer Chevron Cars Ltd, Chevron Cars as a two-seater racing sports car for the makes world championship. Brian Redman won the very first outing, the race at the Nürburgring on September 7, 1969, at a time of 3:13:01.6 hours. The last victory with a Chevron B16 was achieved by Clemens Schickentanz on July 11, 1971, in the sports car race at the Norisring. Design and versions As with the previous Chevron B8, B8, Derek Bennett (1933–1978) used a lattice tube construction with stiffening sheets of steel and aluminum for the chassis. The chassis with double wishbones on all wheels corresponded to the usual. Derek Bennett also designed the fiberglass body, which was manufactured by Specialized Moldings. The first cars were powered by a 1.6 liter Ford Cosworth FVA engine from Formula 2. Thanks to personal contact between Bennett and Keith ...

Manual Transmission
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canadian English, Canada, British English, the United Kingdom and American English, the United States), or stick shift (in the United States), is a multi-speed motor vehicle Transmission (mechanical device), transmission system where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually a foot pedal for cars or a hand lever for motorcycles). Early automobiles used ''sliding-mesh'' manual transmissions with up to three forward gear ratios. Since the 1950s, ''constant-mesh'' manual transmissions have become increasingly commonplace, and the number of forward ratios has increased to 5-speed and 6-speed manual transmissions for current vehicles. The alternative to a manual transmission is an automatic transmission. Common types of automatic transmissions are the Automatic transmission#Hydraulic automatic transmissions, hydraulic automatic ...

Hewland
Hewland is a British engineering company, founded in 1957 by Mike Hewland, which specialises in racing-car gearboxes. Hewland currently employ 130 people at their Maidenhead facility and have diversified into a variety of markets being particularly successful in electric vehicle transmission supply. Hewland are currently supplying into Formula 1, Formula E, DTM, LMP, Rallycross, Prototype and GT Sportscar. At the beginning of 2021, Hewland was acquired by Indian Hero Motors Company. History Mike Hewland ran a small engineering business at Maidenhead in the UK with the speciality in gear cutting. In 1959, Bob Gibson-Jarvie, the Chief Mechanic of UDT Laystall racing team running Cooper F2 cars, sought help from Hewland as gearbox troubles were experienced. The result of this request came out as six successful gearboxes being designed and built in 1959, and Hewland was in the gearbox business. The first transaxle product, the Hewland Mk.I of 1960, was a minor modification of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inline-four Engine
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 ...
