Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called 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). Diesel engines work by compressing only air, or air plus 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 the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volkswagen Polo
The Volkswagen Polo is a supermini car (B-segment) produced by the German car manufacturer Volkswagen since 1975. It is sold in Europe and other markets worldwide in hatchback, saloon, and estate variants throughout its production run. History As of 2018, six separate generations of the Polo have been produced, usually identified by a "Series" or "Mark" number. Some generations were facelifted midway through production, with the updated versions known unofficially by an addition of the letter F to the mark number, e.g. Mk2F. Some members of the automotive press and some enthusiasts consider the facelifts to be separate models, so have used the unofficial designations Polo Mk1 to Mk7 for previous generations. Each Polo model is also identified by a two- or three-character Volkswagen Group ''Typ'' number. Official VW Polo history describes Mark I to Mark IV using either Roman numerals or Arabic numerals, with facelifted variants known as "Phase II" models. The body style has bee ...

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. ...

Turbocharged Direct Injection
TDI (Turbocharged Direct Injection) is Volkswagen Group's term for its current common rail direct injection turbodiesel engine range that have an intercooler in addition to the turbo compressor. TDI engines are used in motor vehicles sold by the Audi, Volkswagen, SEAT and Skoda marques, as well as boat engines sold by in Volkswagen Marine and industrial engines sold by Volkswagen Industrial Motor. The first TDI engine, a straight-five engine, was produced for the 1989 Audi 100 TDI sedan. In 1999, common rail fuel injection was introduced, in the V8 engine used by the Audi A8 3.3 TDI Quattro. From 2006 until 2014, Audi successfully competed in the LMP1 category of motor racing using TDI engine-powered racing cars. TDI engines installed in 2009 to 2015 model year Volkswagen Group cars sold through 18 September 2015 had an emissions defeat device, which activated emissions controls only during emissions testing. The emissions controls were suppressed otherwise, allowing the TDI en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engine Configuration
The engine configuration describes the fundamental operating principles by which internal combustion engines are categorized. Piston engines are often categorized by their cylinder layout, valves and camshafts. Wankel engines are often categorized by the number of rotors present. Gas turbine engines are often categorized into turbojets, turbofans, turboprops and turboshafts. Piston engines Piston engines are usually designed with the cylinders in lines parallel to the crankshaft. It is called a straight engine (or 'inline engine') when the cylinders arranged in a single line. Where the cylinders are arranged in two or more lines (such as in V engines or flat engines), each line of cylinders is referred to as a 'cylinder bank'. The angle between cylinder banks is called the 'bank angle'. Engines with multiple banks are shorter than straight engines and can be designed to cancel out the unbalanced forces from each bank, in order to reduce the vibration. Most engines with fou ...

Volkswagen Jetta
The Volkswagen Jetta () is a compact car/small family car manufactured and marketed by Volkswagen since 1979. Positioned to fill a sedan niche above the firm's Golf hatchback, it has been marketed over seven generations, variously as the Atlantic, Vento, Bora, City Jetta, Jetta City, GLI, Jetta, Clasico, and Sagitar (in China). The Jetta has been offered in two- and four-door saloon / sedan, and five-door wagon / estate versions – all as four- or five-seaters. Since the original version in 1980, the car has grown in size and power with each generation. By mid-2011, almost 10 million Jettas have been produced and sold all over the world. As of April 2014, Volkswagen marketed over 14 million, becoming its top selling model. Nameplate etymology Numerous sources note that the Jetta nameplate derives from the Atlantic 'jet stream' during a period when Volkswagen named its vehicles after prominent winds and currents (e.g., the Volkswagen Passat (after the German word for trade ...

Volkswagen Beetle
The Volkswagen Beetle—officially the Volkswagen Type 1, informally in German (meaning "beetle"), in parts of the English-speaking world the Bug, and known by many other nicknames in other languages—is a two-door, rear-engine economy car, intended for five occupants (later, Beetles were restricted to four people in some countries), that was manufactured and marketed by German automaker Volkswagen (VW) from 1938 until 2003. The need for a ''people's car'' ( in German), its concept and its functional objectives were formulated by the leader of Nazi Germany, Adolf Hitler, who wanted a cheap, simple car to be mass-produced for his country's new road network (Reichsautobahn). Members of the National Socialist party, with an additional dues surcharge, were promised the first production, but the Spanish Civil War shifted most production resources to military vehicles to support the Nationalists under Francisco Franco. Lead engineer Ferdinand Porsche and his team took until 1938 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volkswagen Golf
The Volkswagen Golf () is a compact car/small family car (C-segment) produced by the German automotive manufacturer Volkswagen since 1974, marketed worldwide across eight generations, in various body configurations and under various nameplates – including as the Volkswagen Rabbit in the United States and Canada (Mk1 and Mk5), and as the Volkswagen Caribe in Mexico (Mk1). The original Golf Mk1 was a front-engined, front-wheel drive replacement for the air-cooled, rear-engined, rear-wheel drive Volkswagen Beetle. Historically, the Golf is Volkswagen's best-selling model and is among the world's top three best-selling models, with more than 35 million units sold as of 2019.

Crossflow Cylinder Head
A crossflow cylinder head is a cylinder head that features the intake and exhaust ports on opposite sides. The gases can be thought to flow across the head. This is in contrast to reverse-flow cylinder head designs that have the ports on the same side. Crossflow heads use overhead valves, but these can be actuated either by overhead camshafts, or by a valve-train, which has the camshafts in the cylinder block, and actuates the valves with push rods and rockers.

Overhead Camshaft
An overhead camshaft (OHC) engine is a piston engine where the camshaft is located in the cylinder head above the combustion chamber. This contrasts with earlier overhead valve engines (OHV), where the camshaft is located below the combustion chamber in the engine block. ''Single overhead camshaft'' (SOHC) engines have one camshaft per bank of cylinders. ''Dual overhead camshaft'' (DOHC, also known as "twin-cam".) engines have two camshafts per bank. The first production car to use a DOHC engine was built in 1910. Use of DOHC engines slowly increased from the 1940s, leading to many automobiles by the early 2000s using DOHC engines. Design In an OHC engine, the camshaft is located at the top of the engine, above the combustion chamber. This contrasts the earlier overhead valve engine (OHV) and flathead engine configurations, where the camshaft is located down in the engine block. The valves in both OHC and OHV engines are located above the combustion chamber; however an OHV ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engine Displacement
Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. It is commonly used as an expression of an engine's size, and by extension as a loose indicator of the power an engine might be capable of producing and the amount of fuel it should be expected to consume. For this reason displacement is one of the measures often used in advertising, as well as regulating, motor vehicles. It is usually expressed using the metric units of cubic centimetres (cc or cm3, equivalent to millilitres) or litres (l or L), orparticularly in the United States cubic inches (CID, cu in, or in3). Definition The overall displacement for a typical reciprocating piston engine is calculated by multiplying together three values; the distance travelled by the piston (the stroke length), the circular area of the cylinder, and the number of cylinders in the whole engine. The formula is: : \text = \text \times \frac \times ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
