Renault Safrane
The Renault Safrane is an executive car (E-segment in Europe) designed and built by the France, French manufacturer Renault from 1992 until 2000. Throughout its production it remained the most expensive and most luxurious Renault available, although its commercial success was limited, compared to some similar models and also compared to its predecessor. Just over 300,000 Safranes were built, compared to nearly 800,000 Renault 25. It was replaced by the Renault Vel Satis, Vel Satis, and to some extent, by the short-lived two-door Renault Avantime, Avantime. Since 2008, a new model, based directly on the Renault Samsung SM5#Second generation .28A34R.29, Renault Samsung SM5 sedan, is also called Renault Safrane. Background The Safrane was launched in April 1992, to replace the Renault 25 in the Full-size car, full-size market segment. Its clean, aerodynamic styling was quite conservative and typical of early 1990s car design, also quite reminiscent of the 25's appearance. The Safra ...

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 ...

Europe
Europe is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and Asia to the east. Europe shares the landmass of Eurasia with Asia, and of Afro-Eurasia with both Africa and Asia. Europe is commonly considered to be Boundaries between the continents#Asia and Europe, separated from Asia by the Drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea, and the waterway of the Bosporus, Bosporus Strait. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Black Sea with its outlets, the Bosporus and Dardanelles." Europe covers approx. , or 2% of Earth#Surface, Earth's surface (6.8% of Earth's land area), making it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Sofim 8140 Engine
The 8140 was a diesel engine made by Sofim for cars. Originally introduced as a swirl chamber, naturally aspirated diesel it was mostly used in commercial vehicles worldwide. At the time of introduction, the 8140's overhead camshaft layout (driven by a toothed timingbelt) was unexpected in a diesel engine, which were typically overhead valve designs. Turbocharging the original engine, the design of which was finished in 1974, was impeded until 1985 due to restrictions of the original design. Heat flux issues with the aluminium head and swirl chambers were eventually overcome, but did slow down development. Before entering the market, Fiat tested the Sofim engine in its 131 model during the 1977 London-Sydney Marathon. First direct injection models also appeared in the mid-1980s. Additionally to the Fiat designation 8140 some engines got a Renault tag (S8 for indirect injection, S9 for direct injection). 2.0 L version In the early beginning there was a four-cylinder , c ...

Turbodiesel
The term turbo-diesel, also written as turbodiesel and turbo diesel, refers to any diesel engine equipped with a turbocharger. As with other engine types, turbocharging a diesel engine can significantly increase its efficiency and power output, especially when used in combination with an intercooler. Turbocharging of diesel engines began in the 1920s with large marine and stationary engines. Trucks became available with turbo-diesel engines in the mid-1950s, followed by passenger cars in the late 1970s. Since the 1990s, the compression ratio of turbo-diesel engines has been dropping. Principle Diesel engines are typically well suited to turbocharging due to two factors: * A "lean" air–fuel ratio, caused when the turbocharger supplies excess air into the engine, is not a problem for diesel engines, because the torque control is dependent on the mass of fuel that is injected into the combustion chamber (i.e. air-fuel ratio), rather than the quantity of the air-fuel mixture. * ...

Diesel Engine
The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which Combustion, ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to Mechanics, mechanical Compression (physics), compression; thus, the diesel engine is called a compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Introduction Diesel engines work by compressing only air, or air combined with residual combustion gases from the exhaust (known as exhaust gas recirculation, "EGR"). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases air temperature inside the Cylinder (engine), cylinder so that atomised diesel fuel injected into the combustion chamber ignites. The torque a dies ...

Twin-turbo
Twin-turbo is a type of turbo layout in which two turbochargers are used to compress the intake fuel/air mixture (or intake air, in the case of a direct-injection engine). The most common layout features two identical or mirrored turbochargers in parallel, each processing half of a V engine's produced exhaust through independent piping. The two turbochargers can either be matching or different sizes. The ga70 1ggte was the first inline 6 twin turbo in the world. Types and combinations There are three types of turbine setups used for twin-turbo setups: * Parallel * Sequential * Series These can be applied to any of the five types of compressor setups (which theoretically could have 15 different setups): * Compound Compressors * Staged Compound Compressors * Staged Sequential Compressors * Parallel Sequential Compressors * Parallel Compressors Parallel In a parallel configuration, two equally-sized turbochargers each receive half of the exhaust gases. Some designs combin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PRV Engine
The V6 PRV engine is an overhead cam V6 automobile engine designed and manufactured by the company "Française de Mécanique" for PRV, an alliance of Peugeot, Renault and Volvo Cars. Sold from 1974 to 1998, it was produced in four displacements between 2.5 L and 3.0, and in both SOHC and DOHC and 2-valve and 4-valve per cylinder configurations. Originally carbureted, it adopted fuel-injection for improved emissions compliance and improved performance, and was offered in turbo and biturbo versions in a limited number of vehicles made by Renault, Chrysler Motors, and French supercar manufacturer Venturi. It was gradually replaced after 1994 by another engine jointly developed by Peugeot-successor PSA and Renault, known as the ''ES'' engine at PSA and the ''L'' engine at Renault. Corporate history In 1966, Peugeot and Renault entered a cooperative agreement to manufacture common components. The first joint subsidiary, ''La Française de Mécanique'' (also called ''Compag ...
