VR5 Engine
The VR5 engines are a family of (petroleum fuelled) Internal combustion engines developed by the Volkswagen Group and produced from 1997 to 2006. They are derived from the VR6 engine family, also developed by Volkswagen, but with one fewer cylinders. The VR5 is highly compact, thanks to the narrower angle of 15° and a displacement of . The VR5 was the first production block to use five cylinders in a VR design with a 15-degree angle. Technical Information A VR5 engine block houses two staggered rows of cylinders within a single, short and wide bank – one row of two cylinders and the other having three. This narrow-angle, single bank block makes the five cylinder engine as short as an inline three cylinder, while also having ''single'' inlet and exhaust manifolds. In a transverse layout the three-cylinder row is located towards the front, and in a longitudinal layout towards the right. Due to the narrow bank-angle of the two cylinder rows, the arrangement works as a zig-zag ...

Internal Combustion Engine
An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons (reciprocating engine, piston engine), turbine blades (gas turbine), a Wankel engine, rotor (Wankel engine), or a propulsive nozzle, nozzle (jet engine). This force moves the component over a distance. This process transforms chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to. The first commercially successful internal combustion engines were invented in the mid-19th century. The first modern internal combustion engine, the Otto engine, was designed in 1876 by the German engineer Nicolaus ...

Motronic
Motronic is the trade name given to a range of digital engine control units developed by Robert Bosch GmbH (commonly known as Bosch) which combined control of fuel injection and ignition in a single unit. By controlling both major systems in a single unit, many aspects of the engine's characteristics (such as power, fuel economy, drivability, and emissions) can be improved. Motronic 1.x Motronic M1.x is powered by various i8051 derivatives made by Siemens, usually SAB80C515 or SAB80C535. Code/data is stored in DIL or PLCC EPROM and ranges from 32k to 128k. 1.0 Often known as "Motronic basic", Motronic ML1.x was one of the first digital engine-management systems developed by Bosch. These early Motronic systems integrated the spark timing element with then-existing Jetronic fuel injection technology. It was originally developed and first used in the BMW 7 Series, before being implemented on several Volvo and Porsche engines throughout the 1980s. The components of the Motronic ...

SEAT Toledo
The SEAT Toledo is a small family car produced by the Spanish manufacturer SEAT, part of Volkswagen Group. The Toledo name was first introduced to the SEAT line up in May 1991 being named after a Spanish city with the same name, with the fourth generation being introduced at the end of 2012, for the model year of 2013. Production ended in February 2019, and the nameplate is currently not in use. __TOC__ First generation (''Typ'' 1L; 1991) The initial version of the SEAT Toledo (''Typ'' 1L) was launched as a four-door fastback saloon, and its sales career lasted from May 1991 to March 1999. Technically it was a five-door liftback, as its boot lid opened together with the rear window. This generation of the Toledo was the first SEAT automobile developed entirely under Volkswagen Group ownership, and it was built on the Golf Mk2 Volkswagen Group A2 platform with a 550-litre boot expandable to 1360 litres when folding rear seats, larger in shape and size than the Volkswa ...

Volkswagen Passat (B5)
The Volkswagen Passat (B5) is a large family car which was produced by German manufacturer Volkswagen from 1996 to 2006. The car, based on the Volkswagen Group B5 platform, was originally launched in Germany in 1996 and 1997 in North America and Europe as well as during March 1998 in Australia. Design The new Passat's raked windscreen and smooth underpinnings helped give the sedan a 0.27 coefficient of drag. The B5 Passat included higher-quality interior trim and the availability of luxury options to differentiate it in the marketplace. The car featured fully independent four-link front suspension; and a semi-independent torsion beam for front-wheel-drive models or a fully independent suspension on the 4motion 4WD models.

Volkswagen New Beetle
The Volkswagen New Beetle is a compact car introduced by Volkswagen in 1997, drawing heavy inspiration from the exterior design of the original Beetle. Unlike the original Beetle, the New Beetle has its engine in the front, driving the front wheels, with luggage storage in the rear. It received a facelift in 2005 and was in production until 2011, nearly fourteen years since its introduction. In the 2012 model year, a new Beetle model, the Beetle (A5), replaced the New Beetle. Various versions of this model continued to be produced in Puebla, Mexico, until the final car left the assembly line on 10 July 2019. History At the 1994 North American International Auto Show, Volkswagen unveiled the Concept One, a "retro"-themed concept car with a resemblance to the original Volkswagen Beetle. Designed by J Mays and Freeman Thomas at the company's California design studio, the concept car was based on the platform of the Volkswagen Polo. A red cabriolet concept was featured at ...

Volkswagen Bora
The Volkswagen Bora is a small family car, the fourth generation of the Volkswagen Jetta, and the successor to the Volkswagen Vento. Production of the car began in July 1999. Carrying on the wind nomenclature from previous generations, the car was known as the Volkswagen Bora in much of the world. Bora is a winter wind that blows intermittently over the coast of the Adriatic Sea, as well as in parts of Greece, Russia, Turkey, and the Sliven region of Bulgaria. In North America and South Africa, the Volkswagen Jetta moniker was again kept on due to the continued popularity of the car in those markets. The Mk4 debuted shortly after its larger sibling, the Passat, with rear passenger doors differing from those of a five-door Golf. The car was also offered as an estate/wagon. Options included rain sensor-controlled windshield wipers and automatic climate control. Two new internal-combustion engines were offered, the 1.8-litre turbo four-cylinder (often referred to as the 1.8& ...

Volkswagen Golf Mk4
The Volkswagen Golf Mk4 (or VW ''Type 1J'') is a compact car, the fourth generation of the Volkswagen Golf and the successor to the Volkswagen Golf Mk3. Launched in October 1997 for the 1998 model year, it was the best selling car in Europe in 2001 (though it slipped to second place, behind the Peugeot 206, in 2002). The Mk4 was a deliberate attempt to take the Volkswagen Golf series further upmarket, with a high-quality interior and higher equipment levels. It was replaced in late 2003 for the 2004 model year by the Volkswagen Golf Mk5 in European markets. However, manufacturing continued in South America and China for developing markets until 2014. Design and engineering As with the larger Volkswagen Passat, Passat, launched a year earlier, the MK4 Golf helped form a part of Volkswagen, Volkswagen's strategy of moving its products upmarket to plug a gap between mainstream economy cars and premium cars, with SEAT and Škoda Auto, Škoda, two other VW Group owned marques, pois ...

Variable-length Intake Manifold
In internal combustion engines, a variable-length intake manifold (VLIM),variable intake manifold (VIM), or variable intake system (VIS) is an automobile internal combustion engine manifold technology. As the name implies, VLIM/VIM/VIS can vary the length of the intake tract in order to optimise power and torque across the range of engine speed operation, as well as to help provide better fuel efficiency. This effect is often achieved by having two separate intake ports, each controlled by a valve, that open two different manifolds – one with a short path that operates at full engine load, and another with a significantly longer path that operates at lower load. The first patent issued for a variable length intake manifold was published in 1958, US Patent US2835235 by Daimler Benz AG. There are two main effects of variable intake geometry: ;Swirl: Variable geometry can create a beneficial air swirl pattern, or turbulence in the combustion chamber. The swirling helps distrib ...

Throttle Body
A throttle is a mechanism by which fluid flow is managed by construction or obstruction. An engine's power can be increased or decreased by the restriction of inlet gases (by the use of a throttle), but usually decreased. The term ''throttle'' has come to refer, informally, to any mechanism by which the power or speed of an engine is regulated, such as a car's accelerator pedal. What is often termed a ''throttle'' (in an aviation context) is also called a thrust lever, particularly for jet engine powered aircraft. For a steam locomotive, the valve which controls the steam is known as the regulator. Internal combustion engines In an internal combustion engine, the throttle is a means of controlling an engine's power by regulating the amount of fuel or air entering the engine. In a motor vehicle the control used by the driver to regulate power is sometimes called the throttle, accelerator, or gas pedal. For a gasoline engine, the throttle most commonly regulates the amount of ...

Inlet Manifold
An inlet manifold or intake manifold (in American English) is the part of an internal combustion engine that supplies the fuel/ air mixture to the cylinders. The word ''manifold'' comes from the Old English word ''manigfeald'' (from the Anglo-Saxon ''manig'' anyand ''feald'' epeatedly and refers to the multiplying of one (pipe) into many.manifold, (adv.) "in the proportion of many to one, by many times". AD1526 ''Oxford English Dictionary'', In contrast, an exhaust manifold collects the exhaust gases from multiple cylinders into a smaller number of pipes – often down to one pipe. The primary function of the intake manifold is to ''evenly'' distribute the combustion mixture (or just air in a direct injection engine) to each intake port in the cylinder head(s). Even distribution is important to optimize the efficiency and performance of the engine. It may also serve as a mount for the carburetor, throttle body, fuel injectors and other components of the engine. Du ...
