Alfa Romeo 6
The Alfa Romeo Alfa 6 (Type 119) is an executive car produced by the Italian automaker Alfa Romeo from 1979 to 1986. Its name refers to the six cylinders of the Alfa Romeo V6 engine, which made its first appearance on this car. History On its launch in 1979, the Alfa 6 was the flagship of the Alfa Romeo range. The four-door body was fairly conventional and used a similar style to the existing Alfa Romeo Alfetta, and in fact both vehicles share a great number of parts, including door panels; Design work on the 6 was done prior to the Alfetta, but the fuel crisis of 1973 delayed further development and led to the 6's belated 1979 debut. The styling was not particularly aerodynamic but the drag coefficient was an acceptable 0.41. Power came from an all-new 2.5-litre V6 engine which generated at 5,600 rpm using a total of six carburettors and a single, belt driven camshaft in each cylinder head. Power steering, power windows, central locking, electric wing mirrors and a 25% l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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 ...

Fuel Injection
Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of a fuel injector. This article focuses on fuel injection in reciprocating piston and Wankel rotary engines. All compression-ignition engines (e.g. diesel engines), and many spark-ignition engines (i.e. petrol (gasoline) engines, such as Otto or Wankel), use fuel injection of one kind or another. Mass-produced diesel engines for passenger cars (such as the Mercedes-Benz OM 138) became available in the late 1930s and early 1940s, being the first fuel-injected engines for passenger car use. In passenger car petrol engines, fuel injection was introduced in the early 1950s and gradually gained prevalence until it had largely replaced carburetors by the early 1990s. The primary difference between carburetion and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while carburetion relies on suction crea ...

Robert Bosch GmbH
Robert Bosch GmbH (; ), commonly known as Bosch (styled BOSCH), is a German multinational engineering and technology company headquartered in Gerlingen, Baden-Württemberg, Germany. The company was founded by Robert Bosch in Stuttgart in 1886. Bosch is 94% owned by the Robert Bosch Stiftung, a charitable institution. Although the charity is funded by owning the vast majority of shares, it has no voting rights and is involved in health and social causes unrelated to Bosch's business. Bosch's core operating areas are spread across four business sectors: mobility (hardware and software), consumer goods (including household appliances and power tools), industrial technology (including drive and control) and energy and building technology. In terms of revenue, Bosch is the largest automotive supplier.

Headlight
A headlamp is a lamp attached to the front of a vehicle to illuminate the road ahead. Headlamps are also often called headlights, but in the most precise usage, ''headlamp'' is the term for the device itself and ''headlight'' is the term for the beam of light produced and distributed by the device. Headlamp performance has steadily improved throughout the automobile age, spurred by the great disparity between daytime and nighttime traffic fatalities: the US National Highway Traffic Safety Administration states that nearly half of all traffic-related fatalities occur in the dark, despite only 25% of traffic travelling during darkness. Other vehicles, such as trains and aircraft, are required to have headlamps. Bicycle headlamps are often used on bicycles, and are required in some jurisdictions. They can be powered by a battery or a small generator like a bottle or hub dynamo. History of automotive headlamps Origins The first horseless carriages used carriage lamps ...

Limited Slip Differential
A limited-slip differential (LSD) is a type of differential gear train that allows its two output shafts to rotate at different speeds but limits the maximum difference between the two shafts. Limited-slip differentials are often known by the generic trademark Positraction, a brand name owned by General Motors and originally used for its Chevrolet branded vehicles. In an automobile, such limited-slip differentials are sometimes used in place of a standard differential, where they convey certain dynamic advantages, at the expense of greater complexity. Early history In 1932, Ferdinand Porsche designed a Grand Prix racing car for the Auto Union company. The high power of the design caused one of the rear wheels to experience excessive wheel spin at any speed up to . In 1935, Porsche commissioned the engineering firm ZF to design a limited-slip differential to improve performance. The ZF "sliding pins and cams" became available, and one example was the Type B-70 used during t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Windows
Power windows or electric windows are automobile windows which can be raised and lowered by pressing a button or switch, as opposed to using a crank handle. History A small number of cars in the 1920s, such as the 1925 Flint Model E-55, featured an early form of "automatic windows" which used a fully mechanical, spring loaded system to raise the windows. Packard introduced hydraulic window lifts (power windows) in fall of 1940, for its new 1941 Packard 180 series cars. This was a hydraulic-electric system, called "Hydro-Electric" by Packard. In 1941, the Ford Motor Company followed with the first power windows on the Lincoln Custom (only the limousine and seven-passenger sedans). Cadillac had a straight-electric divider window (but not side windows) on their series 75. Power assists originated in the need and desire to move convertible body-style tops up and down by some means other than human effort. The earliest power assists were vacuum-operated and were offered on Ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Steering
Power steering is a system for reducing a driver's effort to turn a steering wheel of a motor vehicle, by using a power source to assist steering. Hydraulic or electric actuators add controlled energy to the steering mechanism, so the driver can provide less effort to turn the steered wheels when driving at typical speeds, and considerably reduce the physical effort necessary to turn the wheels when a vehicle is stopped or moving slowly. Power steering can also be engineered to provide some artificial feedback of forces acting on the steered wheels. Hydraulic power steering systems for cars augment steering effort via an actuator, a hydraulic cylinder that is part of a servo system. These systems have a direct mechanical connection between the steering wheel and the steering linkage that steers the wheels. This means that power-steering system failure (to augment effort) still permits the vehicle to be steered using manual effort alone. Electric power steering systems use elec ...

Camshaft
A camshaft is a shaft that contains a row of pointed cams in order to convert rotational motion to reciprocating motion. Camshafts are used in piston engines (to operate the intake and exhaust valves), mechanically controlled ignition systems and early electric motor speed controllers. Camshafts in piston engines are usually made from steel or cast iron, and the shape of the cams greatly affects the engine's characteristics. History Trip hammers are one of the early uses of a form of cam to convert rotating motion, e.g. from a waterwheel, into the reciprocating motion of a hammer used in forging or to pound grain. Evidence for these exists back to the Han dynasty in China, and they were widespread by the medieval period. Camshafts were first described by Ismail al-Jazari in 1206. Once the rotative version of the steam engine was developed in the late 18th century, the operation of the valve gear was usually by an eccentric, which turned the rotation of the crankshaft i ...

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 ...

Alfa Romeo 164
The Alfa Romeo 164 (Type 164) is a four-door executive saloon manufactured and marketed by Italian automaker Alfa Romeo from 1987 to 1998, styled by Pininfarina, and cooperatively designed and sharing platforms and numerous elements with the Fiat Croma, Saab 9000 and Lancia Thema. The 164 succeeded the Alfa Romeo 90 and Alfa 6. The 164 was followed by the 166 in 1998, after a combined production total of 273,857 units. The 164 was also the last Alfa Romeo officially sold in the United States until the 2015 launch of the Alfa Romeo Giulia. Alfa Romeo withdrew after the 1995 model year due to reliability concerns and slow sales. Development The 164 started life as ''Project 156'' (not to be confused with Alfa Romeo 156) in 1980 as a proposal by Alfa Romeo engineer Filippo Surace as a modular platform for a range of cars aimed to replace the Alfa Sud and Alfetta. Project 156 was meant to be a rear-wheel drive and powered by the Alfa Romeo's ''Busso'' V6. A saloon body was de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
