Flat-six Engine
A flat-six engine, also known as a horizontally opposed-six, is a six-cylinder piston engine with three cylinders on each side of a central crankshaft. The most common type of flat-six engine is the boxer-six engine, where each pair of opposed cylinders moves inwards and outwards at the same time. The advantages of the flat-six layout are good engine balance (for reduced vibration), a low center of gravity, short length (compared with an inline-six engine) and being well suited to air-cooling. The disadvantages are a large width (which can limit the maximum steering angle when used in a front-engined car), a large intake manifold being required when a central carburetor is used, and duplication of the inlet and outlet connections for water-cooled engines. The first production flat-six engine was in the 1904 ''Wilson-Pilcher 18/24 HP'' car. The most notable use of flat-six engines is the Porsche 911 sports car, which has used flat-six engines continuously since 1963. Several oth ...

Franklin O-335
The Franklin O-335 (company designations variations on 6A and 6V) was an American air-cooled aircraft engine of the 1940s. The engine was of Flat-six engine, six-cylinder, horizontally-opposed layout and Engine displacement, displaced . The power output of later variants was . Design and development These engines were commonly vertically mounted and used to power many early helicopters in the United States. They were closely related to the Franklin 2A4, 2A4 and Franklin 4A4, 4A4 2- and 4-cylinder engines. In various subtypes, the 6A4 remained in continuous production from 1945 to the time Franklin's United States operations ceased in 1975, with versions continuing in Polish production into the 1990s. In 1947 this engine was modified into a water-cooled version by the Preston Tucker, Tucker Car Corporation for use in the 1948 Tucker Sedan. Tucker liked the engine so much that he purchased the Aircooled Motors/Franklin Engine Company, and it remained under the ownership of the ...

Subaru Six-cylinder Engines
The Subaru six-cylinder engines are a series of flat-6 engines manufactured by Subaru, a division of Fuji Heavy Industries, made in three distinct generations. The ER27, derived from the Subaru EA first-generation flat-4, was used as the sole engine option in the premium model 1988–91 Subaru Alcyone VX (XT6 in the United States). The EG33, derived from the Subaru EJ second-generation flat-4, was used exclusively in the successor Subaru Alcyone SVX, again as its sole engine option, sold from 1991–96. The EZ series, consisting of the EZ30 and EZ36 models, was designed to be almost as compact as the EJ25 flat-4. The EZ30/36 were the first Subaru six-cylinder engines available outside the sport coupes, used as the uplevel option for Subaru Legacy (2002–19) and Outback/Lancaster (2001–19) as well as the sole option in the Subaru Tribeca (2006–14). ER27 Created as a refined luxury engine with improved power over the EA82T, Subaru introduced the ER27 engine in November ...

Porsche Boxster/Cayman
The Porsche Boxster and Cayman are mid-engine two-seater sports cars manufactured and marketed by German automobile manufacturer Porsche across four generations—as a two-door, two-seater roadster (Boxster) and a three-door, two-seater fastback coupé (Cayman). The first generation Boxster was introduced in 1996; the second generation Boxster and the Cayman arrived in late 2005; and the third generation launched in 2012. Since the introduction of the fourth generation in 2016, the two models have been marketed as the Porsche 718 Boxster and Porsche 718 Cayman. The nameplate ''Boxster'' is a portmanteau of ''boxer'', a reference to its flat or boxer engine, and '' roadster'', a reference to the body style. The nameplate ''Cayman'' is an alternative spelling of caiman, a member of the alligator family. Overview Boxster The Porsche Boxster is a mid-engine two-seater roadster. It was Porsche's first road vehicle to be originally designed as a roadster since the 914. The fir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rear Engine
In automobile design, a rear-engine design layout places the engine at the rear of the vehicle. The center of gravity of the engine itself is behind the rear axle. This is not to be confused with the center of gravity of the whole vehicle, as an imbalance of such proportions would make it impossible to keep the front wheels on the ground. Rear-engined vehicles almost always have a rear-wheel drive car layout, but some are four wheel drive. This layout has the following features: *Packaging: since there is no need for a transmission tunnel, the floor can be flat. *Rear traction: having the engine located over the driven wheels increases downward pressure, which is helpful for grip on loose surfaces, although can be prone to oversteer. *Simplicity of manufacture: the engine is near the driven wheels, and the transmission can be merged with the differential to save space. This layout was once popular in small, inexpensive cars and light commercial vehicles. Today most car makers hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porsche 959
The Porsche 959 is a sports car manufactured by German automobile manufacturer Porsche from 1986 to 1993, first as a Group B rally car and later as a road legal production car designed to satisfy FIA homologation regulations requiring at least 200 units be produced. The twin-turbocharged 959 was the world's fastest street-legal production car when introduced, achieving a top speed of , with some variants even capable of achieving . During its production run, the 959 was considered the most technologically advanced road-going sports car ever built, and forerunner of all forthcoming sports cars. After the successful introduction of all-wheel drive on more rally-specific cars like the Audi Quattro, it was one of the first pure high-performance sports-cars with all-wheel drive, providing the basis for Porsche's first all-wheel drive 911 Carrera 4 model. Its performance convinced Porsche executives to make all-wheel drive standard on all turbocharged versions of the 911 startin ...

Mid-engine
In automotive engineering, a mid-engine layout describes the placement of an automobile engine in front of the rear-wheel axles, but behind the front axle. History The mid-engine, rear-wheel-drive format can be considered the original layout of automobiles. A 1901 Autocar was the first gasoline-powered automobile to use a drive shaft and placed the engine under the seat. This pioneering vehicle is now in the collection of the Smithsonian Institution. Benefits Mounting the engine in the middle instead of the front of the vehicle puts more weight over the rear tires, so they have more traction and provide more assistance to the front tires in braking the vehicle, with less chance of rear-wheel lockup and less chance of a skid or spin out. If the mid-engine vehicle is also rear-drive the added weight on the rear tires can also improve acceleration on slippery surfaces, providing much of the benefit of all-wheel-drive without the added weight and expense of all-wheel-drive comp ...

Porsche 914
The Porsche 914 or VW-Porsche 914 is a mid-engined sports car designed, manufactured and marketed collaboratively by Volkswagen and Porsche from 1969 until 1976. It was only available as a targa-topped two-seat roadster powered by either a flat-4 or flat-6 engine. History Pre-development By the late 1960s, both Volkswagen and Porsche were in need of new models; Porsche was looking for a replacement for their entry-level 912, and Volkswagen wanted a new range-topping sports coupé to replace the Volkswagen Type 34 Karmann Ghia coupé. At the time the majority of Volkswagen's development work was handled by Porsche as part of an agreement that dated back to Porsche's founding. Volkswagen needed to contract out one last project to Porsche to fulfill the contract, and decided to make the 914 that project. Ferdinand Piëch, who was in charge of research and development at Porsche, was put in charge of the 914 project. In 1966 and 1967, German company Gugelot Design GmbH ...

Water Cooling (engines)
Radiators are heat exchangers used for cooling internal combustion engines, mainly in automobiles but also in piston-engined aircraft, railway locomotives, motorcycles, stationary generating plant or any similar use of such an engine. Internal combustion engines are often cooled by circulating a liquid called '' engine coolant'' through the engine block, and cylinder head where it is heated, then through a radiator where it loses heat to the atmosphere, and then returned to the engine. Engine coolant is usually water-based, but may also be oil. It is common to employ a water pump to force the engine coolant to circulate, and also for an axial fan to force air through the radiator. Automobiles and motorcycles In automobiles and motorcycles with a liquid-cooled internal combustion engine, a radiator is connected to channels running through the engine and cylinder head, through which a liquid (coolant) is pumped. This liquid may be water (in climates where water is unlik ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air-cooled Engine
Air-cooled engines rely on the circulation of air directly over heat dissipation fins or hot areas of the engine to cool them in order to keep the engine within operating temperatures. In all combustion engines, a great percentage of the heat generated (around 44%) escapes through the exhaust, not through the metal fins of an air-cooled engine (12%). About 8% of the heat energy is transferred to the oil, which although primarily meant for lubrication, also plays a role in heat dissipation via a cooler. ''Air-cooled engines'' are used generally in applications which would not suit liquid cooling, as such modern air-cooled engines are used in motorcycles, general aviation aircraft, lawn mowers, generators, outboard motors, pump sets, saw benches and auxiliary power units. Introduction Most modern internal combustion engines are cooled by a closed circuit carrying liquid coolant through channels in the engine block and cylinder head, where the coolant absorbs heat, to ...

Porsche 911 2
Dr. Ing. h.c. F. Porsche AG, usually shortened to Porsche (; see below), is a German automobile manufacturer specializing in high-performance sports cars, SUVs and sedans, headquartered in Stuttgart, Baden-Württemberg, Germany. The company is owned by Volkswagen AG, a controlling stake of which is owned by Porsche Automobil Holding SE. Porsche's current lineup includes the 718 Boxster/Cayman, 911 (992), Panamera, Macan, Cayenne and Taycan. History Origin Ferdinand Porsche (1875–1951) founded the company called "Dr. Ing. h. c. F. Porsche GmbH" with Adolf Rosenberger and Anton Piëch in 1931. The main offices was at Kronenstraße 24 in the centre of Stuttgart. Initially, the company offered motor vehicle development work and consulting, but did not build any cars under its own name. One of the first assignments the new company received was from the German government to design a car for the people; that is, a ''Volkswagen''. This resulted in the Volkswagen Beetle, on ...

Chevrolet Corvair
The Chevrolet Corvair is a compact car manufactured by Chevrolet for model years 1960–1969 in two generations. A response to the Volkswagen Beetle, it remains the only American-designed, mass-produced passenger car with a rear-mounted, air-cooled engine. The Corvair was manufactured and marketed in 4-door sedan, 2-door coupe, convertible, 4-door station wagon, passenger van, commercial van, and pickup truck body styles in its first generation (1960–1964) and as a 2-door coupe, convertible or 4-door hardtop in its second (1965–1969) – with a total production of approximately 1.8 million from 1960 until 1969. The name "Corvair" originated as a portmanteau of Corvette and Bel Air, a name first applied in 1954 to a Corvette-based concept with a hardtop fastback-styled roof, part of the Motorama traveling exhibition. When applied to the production models, the "air" part referenced the engine's cooling system. A prominent aspect of the Corvair's legacy derives fr ...
