Swept Volume
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] |
Displacement
Displacement may refer to: Physical sciences Mathematics and Physics *Displacement (geometry), is the difference between the final and initial position of a point trajectory (for instance, the center of mass of a moving object). The actual path covered to reach the final position is irrelevant. **Particle displacement, a measurement of distance of the movement of a particle in a medium as it transmits a wave (represented in mathematics by the lower-case Greek letter ξ) **Displacement field (mechanics), an assignment of displacement vectors for all points in a body that is displaced from one state to another **Electric displacement field, as appears in Maxwell's equations *Wien's displacement law, a relation concerning the spectral distribution of blackbody radiation *Angular displacement, a change in orientation of a rigid body, the amount of rotation about a fixed axis.

Turbocharger
In an internal combustion engine, a turbocharger (often called a turbo) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake gas, forcing more air into the engine in order to produce more power for a given displacement. The current categorisation is that a turbocharger is powered by the kinetic energy of the exhaust gasses, whereas a supercharger is mechanically powered (usually by a belt from the engine's crankshaft). However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. History Prior to the invention of the turbocharger, |
Compression Ratio
The compression ratio is the ratio between the volume of the cylinder and combustion chamber in an internal combustion engine at their maximum and minimum values. A fundamental specification for such engines, it is measured two ways: the static compression ratio, calculated based on the relative volumes of the combustion chamber and the cylinder when the piston is at the bottom of its stroke, and the volume of the combustion chamber when the piston is at the top of its stroke. The dynamic compression ratio is a more advanced calculation which also takes into account gasses entering and exiting the cylinder during the compression phase. Effect and typical ratios A high compression ratio is desirable because it allows an engine to extract more mechanical energy from a given mass of air–fuel mixture due to its higher thermal efficiency. This occurs because internal combustion engines are heat engines, and higher compression ratios permit the same combustion temperature to ...

Bore (engine)
In a piston engine, the bore (or cylinder bore) is the diameter of each cylinder. Engine displacement is calculated based on bore, stroke length and the number of cylinders: displacement = The stroke ratio, determined by dividing the bore by the stroke, traditionally indicated whether an engine was designed for power at high engine speeds (rpm) or torque at lower engine speeds. The term "bore" can also be applied to the bore of a locomotive cylinder or steam engine pistons. Steam locomotive The term bore also applies to the cylinder of a steam locomotive or steam engine. See also * Bore pitch * Compression ratio * 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.

Active Fuel Management
Active Fuel Management (formerly known as displacement on demand (DoD)) is a trademarked name for the automobile variable displacement technology from General Motors. It allows a V6 or V8 engine to "turn off" half of the cylinders under light-load conditions to improve fuel economy. Estimated performance on EPA tests shows a 5.5–7.5% improvement in fuel economy. GM's current Active Fuel Management technology uses a solenoid to deactivate the lifters on selected cylinders of a pushrod V-layout engine. Third generation In January 2018, GM announced an improved version of AFM called ''Dynamic Fuel Management'' to be initially released in Chevy Silverado trucks. This system shuts off any number of cylinders in a variety of combinations, maximizing fuel economy and avoiding switching between banks of cylinders . The system is based on ''Dynamic Skip Fire,'' a technology developed by California company Tula Technology. The 6.2L V8 engine of the Chevrolet Silverado incorporating ...

Chevrolet Chevelle
The Chevrolet Chevelle is a mid-sized automobile that was produced by Chevrolet in three generations for the 1964 through 1978 model years. Part of the General Motors (GM) A-body platform, the Chevelle was one of Chevrolet's most successful nameplates. Body styles included coupes, sedans, convertibles, and station wagons. The "Super Sport" versions were produced through the 1973 model year, and Lagunas from 1973 through 1976. After a four-year absence, the El Camino was reintroduced as part of the new Chevelle lineup in 1964. The G-body Monte Carlo, introduced in 1970, also used a platform that was based heavily on the Chevelle platform, although it was lengthened ahead of the firewall. From 1964 through 1969, GM of Canada sold a modified version of the Chevelle that included a Pontiac style grille and a LeMans instrument panel, marketed as the Beaumont. The Malibu was the top-of-the-line model through 1972 and completely replaced the Chevelle nameplate starting with th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plymouth Roadrunner
The Plymouth Road Runner is a mid-size car with a focus on performance built by Plymouth in the United States between 1968 and 1980. By 1968, some of the original muscle cars were moving away from their roots as relatively cheap, fast cars as they gained features and increased in price. Plymouth developed the Road Runner to market a lower-priced, basic trim model to its upscale GTX. Origin Plymouth paid $50,000 to Warner Bros.-Seven Arts to use the Road Runner name and likeness from their Wile E. Coyote and the Road Runner cartoons (as well as a " beep, beep" horn, which Plymouth paid $10,000 to develop). The Road Runner was based on the Chrysler B platform (the same as the Belvedere and Satellite), as a back-to-basics mid-size performance car. First generation (1968 to 1970) 1968 The earliest of the 1968 models were available only as 2-door pillared coupes (with a B-pillar or "post" between the front and rear windows), but later in the model year, a 2-door "hardtop" ...

Ford Mustang
The Ford Mustang is a series of American automobiles manufactured by Ford. In continuous production since 1964, the Mustang is currently the longest-produced Ford car nameplate. Currently in its sixth generation, it is the fifth-best selling Ford car nameplate. The namesake of the "pony car" automobile segment, the Mustang was developed as a highly styled line of sporty coupes and convertibles derived from existing model lines, initially distinguished by "long hood, short deck" proportions. Originally predicted to sell 100,000 vehicles yearly, the 1965 Mustang became the most successful vehicle launch since the 1927 Model A. Introduced on April 17, 1964 (16 days after the Plymouth Barracuda), over 400,000 units in its first year; the one-millionth Mustang was sold within two years of its launch. In August 2018, Ford produced the 10-millionth Mustang; matching the first 1965 Mustang, the vehicle was a 2019 Wimbledon White convertible with a V8 engine. The success of the M ...

Muscle Car
Muscle car is a description according to ''Merriam-Webster Dictionary'' that came to use in 1966 for "a group of American-made two-door sports coupes with powerful engines designed for high-performance driving." The '' Britannica Dictionary'' describes these as "an American-made two-door sports car with a powerful engine." Although the term was unknown for another fifteen-plus years, General Motors is credited by some as introducing the first "intentional" muscle car in 1949, when it put its Rocket V8 from its full-sized luxury car 98 model into the considerably smaller and lighter Oldsmobile 88. The competition between American manufacturers started when Chrysler installed the Chrysler Hemi engine in the mid-range Chrysler Saratoga in 1951 that was normally installed in the full-sized luxury sedan Chrysler New Yorker. In 1952 Ford's luxury brand Lincoln introduced the Lincoln Y-Block V8 and the rivalry began, where the Lincoln Capri was entered in the Pan American Road ...

Lexus LS
The is a full-size luxury sedan (F-segment in Europe) serving as the flagship model of Lexus, the luxury division of Toyota. For the first four generations, all LS models featured V8 engines and were predominantly rear-wheel-drive. In the fourth generation, Lexus offered all-wheel-drive, hybrid, and long-wheelbase variants. The fifth generation changed to using a V6 engine with no V8 option, and only one length was offered. As the first model developed by Lexus, the LS 400 debuted in January 1989 with the second generation debuting in November 1994. The LS 430 debuted in January 2000 and the LS 460/LS 460 L series in 2006. A domestic-market version of the LS 400 and LS 430, badged as , was sold in Japan until the Lexus marque was introduced there in 2006. In 2006 (for the 2007 model year), the fourth generation LS 460 debuted the first production eight-speed automatic transmission and an automatic parking system. In 2007, V8 hybrid powertrains were introduced on the LS 600h/LS ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BMW New Class
The BMW New Class (german: Neue Klasse) was a line of sedans and coupes produced by German automaker BMW between 1962 and 1977. These models ensured BMW's solvency after the company's financial crisis of the 1950s and established the identity of BMW automobiles as sports sedans. The first New Class vehicle was the 1500, a 4-door compact executive car with the new M10 (at the time called M115) OHC 4-cylinder engine. In 1965, the 2000C and 2000CS luxury coupés were added to the range. Replacement of the New Class models began with the larger 2000C and 2000CS coupés, which were replaced by the 6-cylinder E9 2800CS in 1969. In 1972, the 4-door sedans were replaced by the larger E12 5 Series. The New Class coupes introduced the Hofmeister kink, which has been used on most BMW cars since. Another legacy of the New Class is the iconic 02 Series, which are a shortened version of the New Class sedans. Overview Background During the 1950s, the BMW line-up consisted of luxury car ...

Cadillac Type V-63
The Cadillac V-63 is a large luxury automobile that was introduced in September 1923 by Cadillac as a 1924 model, replacing the previous Type 61. It used the GM C platform and was replaced by the Cadillac Series 355 in 1931. It retained the name Cadillac V8 introduced with the previous generation Cadillac Type 51. The V-63 used an improved version of the L-head V8 engine that made Cadillac famous. The main innovation was a cross-plane crankshaft which improved balance and smoothness. This design required complex mathematical analysis, and was simultaneously patented by Peerless. Both companies agreed to share the innovation, which became a market distinction being able to exclusively offer a V8. For model year 1924, the Packard Eight straight-eight was now a competitor due to its reduced vibration. The body style choices were expanded to 14 while commercial applications weren't offered. New innovations included the availability of Balloon tires mounted on either wire wheels o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
