Flat-6
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 ...

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 1985 ...

Porsche 911
The Porsche 911 (pronounced ''Nine Eleven'' or in german: Neunelfer) is a two-door 2+2 high performance rear-engined sports car introduced in September 1964 by Porsche AG of Stuttgart, Germany. It has a rear-mounted flat-six engine and originally a torsion bar suspension. The car has been continuously enhanced through the years but the basic concept has remained unchanged.Corlett, p. 12 The engines were air-cooled until the introduction of the 996 series in 1998. The 911 has been raced extensively by private and factory teams, in a variety of classes. It is among the most successful competition cars. In the mid-1970s, the naturally aspirated 911 Carrera RSR won world championship races including Targa Florio and the 24 Hours of Daytona. The 911-derived 935 turbo also won the 24 Hours of Le Mans in 1979. Porsche won the World Championship for Makes in 1976, 1977, 1978, and 1979 with 911-derived models. In a 1999 poll to determine the Car of the Century, the 911 was f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tucker 48
The Tucker 48, commonly referred to as the Tucker Torpedo, was an automobile conceived by Preston Tucker while in Ypsilanti, Michigan and briefly produced in Chicago, Illinois in 1948. Only 51 cars were made including their prototype before the company was forced to declare bankruptcy and cease all operations on March 3, 1949, due to negative publicity initiated by the news media, a Securities and Exchange Commission investigation, and a heavily publicized stock fraud trial (in which the allegations were proven baseless and led to a full acquittal). Tucker suspected that the Big Three automakers and Michigan Senator Homer S. Ferguson had a role in the Tucker Corporation's demise. The 48's original proposed price was said to be $1,000, but the actual selling price was closer to $4,000. The 1988 movie '' Tucker: The Man and His Dream'' is based on the saga surrounding the car's production. The film's director, Francis Ford Coppola, is a Tucker owner and displays his vehicle on th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 G ...

Boxer Engine
A flat engine is a piston engine where the cylinders are located on either side of a central crankshaft. Flat engines are also known as horizontally opposed engines, however this is distinct from the less common opposed-piston engine design, whereby each cylinder has two pistons sharing a central combustion chamber. The most common configuration of flat engines is the boxer engine configuration, in which the pistons of each opposed pair of cylinders move inwards and outwards at the same time. The other configuration is effectively a V engine with a 180-degree angle between the cylinder banks; in this configuration each pair of cylinders shares a single crankpin, so that as one piston moves inward, the other moves outward. The first flat engine was built in 1897 by Karl Benz. Flat engines have been used in aviation, motorcycle and automobile applications. They are now less common in cars than straight engines (for engines with less than six cylinders) and V engines (for engines ...

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 six-cylinder, horizontally-opposed layout and 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 2A4 and 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 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 The Franklin Engine Company was an American manufacturer of aircraft engines.

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 starting w ...

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 compon ...

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 unl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
