Nissan RB Engine
The RB engine is an oversquare 2.0–3.0 L straight-6 Four-stroke cycle, four-stroke Petrol engine, gasoline engine from Nissan, originally produced from 1985 to 2004. The RB followed the 1983 Nissan VG engine, VG-series V6 engines to offer a full, modern range in both straight or V layouts. It was part of a new engine family name PLASMA (Powerful ＆ Economic, Lightweight, Accurate, Silent, Mighty, Advanced). The RB engine family includes single overhead camshaft (SOHC) and double overhead camshaft (DOHC) engines. Both SOHC and DOHC versions have an aluminium head. The SOHC versions have 2 valves per cylinder and the DOHC versions have 4 valves per cylinder; each cam lobe moves only one valve. All RB engines have belt driven cams and a cast iron block. Most turbo models have an intercooled turbo (the exceptions being the single cam RB20ET & RB30ET engines), and most have a recirculating factory Blowoff valve, blow off valve (the exceptions being when fitted to Nissan Laure ...

Nissan Skyline GT-R
The is a Japanese sports car based on the Nissan Skyline range. The first cars named "Skyline GT-R" were produced between 1969 and 1972 under the model code KPGC10, and were successful in Japanese touring car racing events. This model was followed by a brief production run of second-generation cars, under model code KPGC110, in 1973. After a 16-year hiatus, the GT-R name was revived in 1989 as the BNR32 ("R32") Skyline GT-R. Group A specification versions of the R32 GT-R were used to win the Japanese Touring Car Championship for four years in a row. The R32 GT-R also had success in the Australian Touring Car Championship, with Jim Richards using it to win the championship in 1991 and Mark Skaife doing the same in 1992, until a regulation change excluded the GT-R in 1993. The technology and performance of the R32 GT-R prompted the Australian motoring publication ''Wheels'' to nickname the GT-R "Godzilla" in its July 1989 edition. ''Wheels'' then carried the name through all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nissan L Engine
The Nissan Motors, Nissan L series of automobile engines was produced from 1966 through 1986 in both Inline-four engine, inline-four and Straight-six engine, inline-six configurations ranging from 1.3 L to 2.8 L. It is a two-valves per cylinder SOHC non-crossflow engine, with an iron block and an aluminium head. It was most notable as the engine of the Datsun 510, Datsun 240Z sports car, and the Nissan Maxima. These engines are known for their reliability, durability, and parts interchangeability. The four-cylinder L series engines were replaced with the Nissan Z engine, Z series and later the Nissan CA engine, CA series, while the six-cylinder L series engines were replaced with the Nissan VG engine, VG series and Nissan RB engine, RB series. History The L series started with the production of the six-cylinder L20 in 1966. This engine was rushed into production by Datsun and was designed prior to the Prince merger using the Mercedes overhead cam engine as a model. and was disconti ...

Nissan Laurel
The is a two- and four-door sedan manufactured and marketed by Nissan from 1968 to 2002. Later generations added all-wheel-drive along with turbocharged engines. Introduced in 1968 as a new model positioned above the Nissan Bluebird#510 series, Datsun Bluebird 510, the Laurel offered the luxury of the Nissan Gloria#Third generation A30, Nissan Gloria A30 in a shorter wheelbase, and always was the luxury version of the Nissan Skyline, Skyline range for all generations, sharing engines, suspensions and handling dynamics of the popular performance coupe and sedan while having a longer wheelbase. The first Laurel was developed by the Nissan Tsurumi-ku, Yokohama, Tsurumi R&D Division and assembled at the Musashimurayama Plant of the former Prince Motor Company in 2-door and 4-door variants beginning in 1968. The Laurel was not marketed new in Japan at ''Nissan Prince Store'' locations that sold the Skyline and Gloria, former Prince products. Instead the Laurel was sold at ''Nissan Mot ...

Blowoff Valve
A blowoff valve (also called dump valve or compressor bypass valve) is a pressure release system present in most petrol turbocharged engines. Blowoff valves are used to reduce pressure in the intake system as the throttle is closed, thus preventing compressor surge. Design A key function of blowoff valves is to prevent compressor surge, a phenomenon that would otherwise occur as the throttle is closed in a turbocharged engine. If the turbocharger's compressor wheel is spinning at high speed when the throttle is suddenly closed (such as during a gear change), the flow reduces beyond the surge line of the compressor. At this point the change in pressure across the compressor reduces, leading to a collapse in flow and possibly even flow reversal and a collapse in plenum pressure. As the compressor is still spinning at high speed, once the flow has reduced sufficiently, the change in pressure across the compressor begins to rise and flow is re-established into the plenum. This rap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intercooled
An intercooler is a heat exchanger used to cool a gas after compression. Often found in turbocharged engines, intercoolers are also used in air compressors, air conditioners, refrigeration and gas turbines. Internal combustion engines Most commonly used with turbocharged engines, an intercooler is used to counteract the heat of compression and heat soak in the pressurised intake air. By reducing the temperature of the intake air, the air becomes denser (allowing more fuel to be injected, resulting in increased power) and less likely to suffer from pre-ignition or knocking. Additional cooling can be provided by externally spraying a fine mist onto the intercooler surface, or even into the intake air itself, to further reduce intake charge temperature through evaporative cooling. Intercoolers can vary dramatically in size, shape and design, depending on the performance and space requirements of the system. Many passenger cars use either front-mounted intercoolers located ...

Belt Drive
A belt is a loop of flexible material used to link two or more rotating shafts mechanically, most often parallel. Belts may be used as a source of motion, to transmit power efficiently or to track relative movement. Belts are looped over pulleys and may have a twist between the pulleys, and the shafts need not be parallel. In a two pulley system, the belt can either drive the pulleys normally in one direction (the same if on parallel shafts), or the belt may be crossed, so that the direction of the driven shaft is reversed (the opposite direction to the driver if on parallel shafts). The belt drive can also be used to change the speed of rotation, either up or down, by using different sized pulleys. As a source of motion, a conveyor belt is one application where the belt is adapted to carry a load continuously between two points. History The mechanical belt drive, using a pulley machine, was first mentioned in the text of the ''Dictionary of Local Expressions'' by the Han ...

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 ...

Nissan VG Engine
The VG engine is a family of V6 engines designed and produced by Nissan between 1983 and 2004. Nissan's and Japan's first mass-produced V6, the iron block/aluminum head 60° VG engine was produced in displacements between 2.0 and 3.3 liters. Early versions used SOHC cylinder heads with two valves per cylinder; later models featured DOHC cylinder heads, four valves per cylinder, a slightly different engine block and N-VCT, Nissan's own version of variable valve timing, delivering a smoother idle and more torque at low to medium engine speeds. Both production blocks and head castings were used successfully in the Nissan GTP ZX-Turbo and NPT-90 race cars which won the IMSA GT Championship three years in a row. Origins Development of the ''VG'' series began in 1979 by Nissan Machinery, a former member of the Nissan Group ''keiretsu''. The objective was to replace the inline 6 Nissan L engine, which traces its roots back to the Mercedes-Benz M180 engine introduced in 1951, with ...

Four-stroke Cycle
A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: #Intake: Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing a partial vacuum (negative pressure) in the cylinder through its downward motion. #Compression: This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (below). Both the intake and exhaust valves are closed during this stage. #Combustion: Also known as power or ignition. This is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Straight-6
A straight-six engine (also referred to as an inline-six engine; abbreviated I6 or L6) is a piston engine with six cylinders arranged in a straight line along the crankshaft. A straight-six engine has perfect primary and secondary engine balance, resulting in fewer vibrations than other designs of six or fewer cylinders. Until the mid-20th century, the straight-six layout was the most common design for engines with six cylinders. However, V6 engines gradually became more common in the 1970s and by the 2000s, V6 engines had replaced straight-six engines in most light automotive applications. Characteristics In terms of packaging, straight-six engines are almost always narrower than a V6 engine or V8 engine, but longer than straight-four engines, V6s, and most V8s. Compared to V-configuration engines with similar power and displacement, the straight configuration has fewer injectors, a single head, and a single exhaust manifold, all contributing to better reliability and perfor ...

Oversquare
Stroke ratio, today universally defined as bore/stroke ratio, is a term to describe the ratio between cylinder bore diameter and piston stroke length in a reciprocating piston engine. This can be used for either an internal combustion engine, where the fuel is burned within the cylinders of the engine, or external combustion engine, such as a steam engine, where the combustion of the fuel takes place ''outside'' the working cylinders of the engine. Conventions The contemporary convention for describing the ''stroke ratio'' of a piston engine‘s cylinders is its ''bore/stroke'' ratio. ''Stroke/bore'' ratio is an obsolete expression dating to the early era of reciprocating engine development. Bore/stroke ratio The diameter of the cylinder bore is divided by the length of the piston stroke to give the ratio. Square, oversquare and undersquare engines The following terms describe the naming conventions for the configurations of the various bore/stroke ratio: Square A square ...

Aluminium
Aluminium (or aluminum in North American English) is a chemical element; it has chemical symbol, symbol Al and atomic number 13. It has a density lower than that of other common metals, about one-third that of steel. Aluminium has a great affinity towards oxygen, passivation (chemistry), forming a protective layer of aluminium oxide, oxide on the surface when exposed to air. It visually resembles silver, both in its color and in its great ability to reflect light. It is soft, magnetism, nonmagnetic, and ductility, ductile. It has one stable isotope, 27Al, which is highly abundant, making aluminium the abundance of the chemical elements, 12th-most abundant element in the universe. The radioactive decay, radioactivity of aluminium-26, 26Al leads to it being used in radiometric dating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ ...
