Alfa Romeo Alfetta
The Alfa Romeo Alfetta (Type 116) is a front-engine, five-passenger saloon and fastback coupé manufactured and marketed by Italian automaker Alfa Romeo from 1972 to 1987 with a total of over 400,000 units produced during its production run. The Alfetta was noted for the rear position of its transaxle (clutch and transmission) and its De Dion tube rear suspension — an arrangement designed to optimize handling by balancing front/rear weight distribution, as well as maintaining a low polar moment of inertia and low center of gravity. The interior of Coupé models featured a then unusual central tachometer placement — by itself, directly in front of the driver. The ''Alfetta'' name, which means "little Alfa" in Italian is derived from the nickname of the Alfa Romeo Alfetta (Tipo 159), a successful Formula One car which in its last iteration introduced in 1951, paired a transaxle layout to De Dion tube rear suspension — like its modern namesake.

Alfa Romeo
Alfa Romeo Automobiles S.p.A. () is an Italian carmaker known for its sports-oriented vehicles, strong auto racing heritage, and iconic design. Headquartered in Turin, Italy, it is a subsidiary of Stellantis Europe and one of 14 brands of multinational automotive company Stellantis. Founded on 24 June 1910 in Milan, Italy as A.L.F.A.—an acronym for ''Anonima Lombarda Fabbrica Automobili''—the company was established by Cavaliere Ugo Stella to acquire the assets of the ailing Italian subsidiary of French carmaker Darracq, of which he had been an investor and manager. Its first car was the 24 HP, designed by Giuseppe Merosi, which became commercially successful and participated in the 1911 Targa Florio endurance race. In August 1915, ALFA was acquired by Neapolitan entrepreneur and engineer Nicola Romeo, who vastly expanded the company's portfolio to include heavy machinery and aircraft engines. In 1920, the company's name was changed to Alfa Romeo, with the Torpedo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Formula One Car
A Formula One car or F1 car is a single-seat, open-cockpit, open-wheel racing car, open-wheel formula racing car used to compete in Formula One racing events. It has substantial front and rear wings, large wheels, and a turbocharged engine mid-engine design, positioned behind the driver. The cars are constructed of carbon fibre and other composite materials for durability and are built to withstand high impact forces and considerable g forces. The early F1 cars were simpler designs with no wings, front mounted engines, and required significant driver effort to control. Later improvements saw the introduction of lighter cars due to metallurgical advancements, introduction of ground effect (aerodynamics), ground effect cars with the addition of wings and other aerodynamic surfaces, and control electronics. The introduction of turbocharged engines with higher efficiency, and energy recovery system to boost speeds led to faster and efficient racing cars. A modern F1 car has a car ...

Alfa Romeo Twin Cam Engine
The Alfa Romeo Twin Cam engine is an all-alloy inline-four engine series produced by Alfa Romeo from 1954 to 1994. In Italian it is known as the "bialbero" ("twin-shaft"), and has also been nicknamed the "Nord" (North) engine in reference to its being built in Portello, Milan (later Arese, close to Milan), in the North of Italy and to distinguish it from the Alfa Romeo Boxer engine built in the South (Sud) for the Alfasud. History The Twin Cam's predecessor appeared in the 1950 Alfa Romeo 1900 and was an under-square inline four cylinder with a cast-iron block, an aluminium alloy crossflow cylinder head with double overhead cams and a 90° included angle between intake and exhaust valves. Development of that engine was overseen by Orazio Satta Puliga who would also helm development of its successor. The 1952 Disco Volante had a 2-litre DOHC four cylinder engine with an aluminium block and sleeves, but this seems to have been a custom version of the 1900 engine rather tha ...

Petrol Engine
A petrol engine (gasoline engine in American and Canadian English) is an internal combustion engine designed to run on petrol (gasoline). Petrol engines can often be adapted to also run on fuels such as liquefied petroleum gas and ethanol blends (such as '' E10'' and '' E85''). They may be designed to run on petrol with a higher octane rating, as sold at petrol stations. Most petrol engines use spark ignition, unlike diesel engines which run on diesel fuel and typically use compression ignition. Another key difference to diesel engines is that petrol engines typically have a lower compression ratio. History The first practical petrol engine was built in 1876 in Germany by Nicolaus August Otto and Eugen Langen, although there had been earlier attempts by Étienne Lenoir in 1860, Siegfried Marcus in 1864 and George Brayton in 1873. Design Thermodynamic cycle Most petrol engines use either the four-stroke Otto cycle or the two-stroke cycle. Petrol engines have also ...

Executive Car
Executive car is a British term for a large car, and is considered equivalent to the European E-segment and American full-size classifications. Executive cars are larger than compact executive cars (and the non-luxury equivalent mid-size cars), but smaller than luxury saloons / full-size luxury sedans. The term has also been adopted by Euro NCAP, a European organization founded to test car safety. Background The term was coined in the 1960s to describe cars targeted at successful professionals and middle-to-senior managers. It was used by businesses as an incentive for employees in senior roles and to exploit Britain and Europe's tax schemes as a company-owned vehicle. Early executive cars typically offered engines with displacements of , compared with for an equivalent sized—but less luxurious—"large family car". Prior to the 1990s, executive cars were typically sedans; however, in recent years, they have also been produced in other body styles, such as estates (s ...

V8 Engine
A V8 engine is an eight- cylinder piston engine in which two banks of four cylinders share a common crankshaft and are arranged in a V configuration. Origins The first known V8 was the Antoinette, designed by Léon Levavasseur, and built in 1904 by the French Antoinette company for use in speedboat racing, cars, and later, airplanes. Also in 1904, V8 engines began small-scale production by Renault and Buchet for use in race cars. Design V-angle Most engines use a V-angle (the angle between the two banks of cylinders) of 90 degrees. This angle results in good engine balance, which results in low vibrations. However, the downside is the greater width of the engine compared to those that use a smaller V-angle. V8 engines with a 60-degree V-angle were used in the 1996–1999 Ford Taurus SHO, the 2005–2011 Volvo XC90, and the 2006–2009 Volvo S80. The Ford engine used a 60-degree V-angle because it was based on a V6 engine with a 60-degree V-angle. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V6 Engine
A V6 engine is a six- cylinder piston engine where the cylinders and cylinder blocks share a common crankshaft and are arranged in a V configuration. The first V6 engines were designed and produced independently by Marmon Motor Car Company, Deutz Gasmotoren Fabrik and Delahaye. Engines built after World War II include the Lancia V6 engine in 1950 for the Lancia Aurelia, and the Buick V6 engine in 1962 for the Buick Special. The V6 layout has become the most common layout for six-cylinder automotive engines. Design Due to their short length, V6 engines are often used as the larger engine option for vehicles which are otherwise produced with inline-four engines, especially in transverse engine vehicles. A downside for luxury cars is that V6 engines produce more vibrations than straight-six engines. Some sports cars like the Porsche 911 use flat-six engines instead of V6 engines, due to their near perfect primary engine balance and lower centre of gravity (which ...

Straight-four Engine
A straight-four engine (also referred to as an inline-four engine) is a four-cylinder Reciprocating engine, 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-4 engine, 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 ...

Pirelli Cinturato
The Pirelli Cinturato is a Pirelli-developed car tyre (wheel), tyre that was the first example of a wrap-around radial tyre structure. It was used to good effect in motorsport, and most modern tyres are based upon the design. The five-times Formula One World Champion Juan Manuel Fangio called the Pirelli Cinturato "Extraordinary" and raced on it many times in the remainder of his career. History First developed in 1952 under the name Pirelli Cintura, taking the name Cinturato in 1963, the tyre was composed of two or three carcass plies of cords laid at an angle of 90 degrees to the beads, and a belt of several plies laid circumferentially under the Tire tread, tread. Without a belt, the 90-degree plies would produce a casing which would greatly increase its sectional height on inflation. The belt, being inextensible, prevented the casing increasing in height when inflated, and the inflated tyre maintained almost the same dimensions as in the mould in which it went through sulf ...

Torsion Bar Suspension
A torsion bar suspension, also known as a torsion spring suspension, is any vehicle suspension that uses a torsion bar as its main weight-bearing spring. One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end terminates in a lever, the torsion key, mounted perpendicular to the bar, that is attached to a suspension arm, a spindle, or the axle. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar's torsion resistance. The effective spring rate of the bar is determined by its length, cross section, shape, material, and manufacturing process. Usage Torsion bar suspensions are used on combat vehicles and tanks like the T-72, Leopard 1, Leopard 2, M26 Pershing, M18 Hellcat, M46/M47/M48 Patton, M60 and the M1 Abrams (many tanks from World War II used this suspension), and on modern trucks and SUVs from Ford, Chrysler, GM, Mitsubishi, Mazda, Nissan, Isuzu, LuAZ, and Toyota.

Double Wishbone Suspension
A double wishbone suspension is an independent suspension design for automobiles using two (occasionally parallel) wishbone-shaped arms to locate the wheel. Each wishbone or arm has two mounting points to the chassis and one joint at the knuckle. The shock absorber and coil spring mount to the wishbones to control vertical movement. Double wishbone designs allow the engineer to carefully control the motion of the wheel throughout suspension travel, controlling such parameters as camber angle, caster angle, toe pattern, roll center height, scrub radius, scuff ( mechanical abrasion), and more. Implementation The double-wishbone suspension can also be referred to as "double A-arms", though the arms themselves can be A-shaped or L-shaped. A single wishbone or A-arm can also be used in various other suspension types, such as variations of the MacPherson strut. The upper arm is usually shorter to induce negative camber as the suspension jounces (rises), and often this arrangement ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
