Opel Rekord B
The Opel Rekord Series B is an executive car that was introduced in August 1965, by Opel as a replacement for the Opel Rekord Series A. The Rekord B shared the wheelbase and 1696mm width of its predecessor, but the front and rear panels were restyled in order effectively to differentiate the new model. The big news was under the bonnet/hood, however. Previous Rekords were noteworthy for combining eye-catching new bodies with a robust four cylinder engine that dated back to 1937. By the 1960s the old engine was perceived as outdated in terms of refinement and sophistication, and with the Rekord B it was replaced. Unlike previous Rekords, the Rekord B featured completely new four cylinder engines, now with a camshaft integrated into the cylinder head. The units were still not conventional ohc engines since the camshaft was physically located lower than the tops of the cylinder valves. The configuration had been developed by General Motors in Detroit and was known as the Camshaft in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opel
Opel Automobile GmbH (), usually shortened to Opel, is a German automobile manufacturer which has been a subsidiary of Stellantis since 16 January 2021. It was owned by the American automaker General Motors from 1929 until 2017 and the PSA Group, a predecessor of Stellantis, from 2017 until 2021. Opel vehicles are sold in the United Kingdom as Vauxhall Motors, Vauxhall. Some Opel vehicles were badge engineering, badge-engineered in Australia under the Holden brand until 2020 and in North America and China under the Buick, Saturn Corporation, Saturn, and Cadillac brands. Opel traces its roots to a sewing machine manufacturer founded by Adam Opel in 1862 in Rüsselsheim am Main. The company began manufacturing bicycles in 1886 and produced its first automobile in 1899. With the Opel RAK program, the world's first rocket program, under the leadership of Fritz von Opel, the company played an important role in the history of aviation and spaceflight: Various land speed records were a ...

Camshaft
A camshaft is a shaft that contains a row of pointed cams, in order to convert rotational motion to reciprocating motion. Camshafts are used in piston engines (to operate the intake and exhaust valves), mechanically controlled ignition systems and early electric motor speed controllers. Camshafts in piston engines are usually made from steel or cast iron, and the shape of the cams greatly affects the engine's characteristics. History Trip hammers are one of the early uses of a form of cam to convert rotating motion, e.g. from a waterwheel, into the reciprocating motion of a hammer used in forging or to pound grain. Evidence for these exists back to the Han Dynasty in China, and they were widespread by the medieval period. The camshaft was described in 1206 by engineer Al-Jazari. He employed it as part of his automata, water-raising machines, and water clocks such as the castle clock. Once the rotative version of the steam engine was developed in the late 18th century, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zenith
The zenith (, ) is an imaginary point directly "above" a particular location, on the celestial sphere. "Above" means in the vertical direction (plumb line) opposite to the gravity direction at that location (nadir). The zenith is the "highest" point on the celestial sphere. Origin The word "zenith" derives from an inaccurate reading of the Arabic expression (), meaning "direction of the head" or "path above the head", by Medieval Latin scribes in the Middle Ages (during the 14th century), possibly through Old Spanish. It was reduced to "samt" ("direction") and miswritten as "senit"/"cenit", the "m" being misread as "ni". Through the Old French "cenith", "zenith" first appeared in the 17th century. Relevance and use The term ''zenith'' sometimes means the highest point, way, or level reached by a celestial body on its daily apparent path around a given point of observation. This sense of the word is often used to describe the position of the Sun ("The sun reached its zenit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solex Carburetor
Solex is a French manufacturer of carburetors and the powered bicycle VéloSoleX. Solex carburetors were used by many European automobile companies and were licensed to Japanese maker Mikuni. History The Solex company was founded by Marcel Mennesson and Maurice Goudard to manufacture vehicle radiators. These were fitted to several makes of early cars including Delaunay-Belleville and buses of the Paris General Omnibus company. After World War I, the radiator business went into decline and the company bought the rights to the carburetor patents of Jouffret and Renée and named them Solex after their business. The Solex brand is now owned by Magneti Marelli. The original Solex company changed its name in 1994 to Magneti Marelli France and on May 31, 2001, Magneti Marelli France partially bought its assets (including the trademark SOLEX) from Magneti Marelli Motopropulsion France S.A.S. Carburetors Solex carburetors were widely used by many European makers and under license to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gear
A gear is a rotating circular machine part having cut teeth or, in the case of a cogwheel or gearwheel, inserted teeth (called ''cogs''), which mesh with another (compatible) toothed part to transmit (convert) torque and speed. The basic principle behind the operation of gears is analogous to the basic principle of levers. A gear may also be known informally as a cog. Geared devices can change the speed, torque, and direction of a power source. Gears of different sizes produce a change in torque, creating a mechanical advantage, through their ''gear ratio'', and thus may be considered a simple machine. The rotational speeds, and the torques, of two meshing gears differ in proportion to their diameters. The teeth on the two meshing gears all have the same shape. Two or more meshing gears, working in a sequence, are called a gear train or a '' transmission''. The gears in a transmission are analogous to the wheels in a crossed, belt pulley system. An advantage of gears is tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volkswagen K70
The Volkswagen K70 is a four-door, front engine, front wheel drive sedan developed by NSU and marketed from 1970–1975 by Volkswagen after its 1969 acquisition of NSU. Designed by NSU's chief engineer Ewald Praxl and styled by Claus Luthe as a four-door sedan (and five-door wagon) to complement the NSU Ro80, the K70 would become the first Volkswagen with a front-mounted engine, water cooling and front wheel drive. Competing with VW's own 411/412 and Audi's 100, the K70 was ultimately sold only as a sedan, with 211,127 examples manufactured for model years 1970–1975. The ''K70'' retained NSU's naming convention, as introduced with the Ro 80 — with ''K'' denoting the German word ''Kolben'' (piston) and ''70'' designating an engine output of . Development The K70 was originally developed to complement the Ro 80, distinguished by its conventional piston engine rather than the Ro80's Wankel rotary engine. NSU scheduled the press launch for March 1969, intending to prese ... [...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 ...

Opel Olympia
The Opel Olympia is a compact car by German automaker Opel, then part of G.M., from 1935 to 1940, and after World War II continued from 1947 to 1953. It was one of the world's first mass-produced cars with a unitary body structure, after the 1934 Citroën Traction Avant; and it was a mass-production success, made in six-figure numbers. Opel achieved this even before the war, all while Hitler promised Germany a "Volkswagen" - a'' 'People's car','' which didn't materialize until 1946. From 1967-1970 the Olympia badge was briefly reused on a later car. The 1935 Olympia was Germany's first mass-produced car with an advanced all-metal unitary body - even a full monocoque in the case of the closed-roof saloon models. This for its time revolutionary technology supplanted the previously customary vehicle body, supported on top of a separate load-bearing chassis, reducing the car's weight by up to 180 kilograms (400 lb.) compared to its predecessor. Production of the unibody design ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opel Rekord
The Opel Rekord is a large family car which was built in eight generations by the German car manufacturer Opel. Between 1953 and 1986, approximately ten million were sold. In 1986, the Rekord nameplate was replaced by the Opel Omega. Naming The Rekord name evolved into the main name of the model; at first the name was used in close relationship with the Opel Olympia name, which pre-dated the Rekord but was also reinstated in a separate model in 1967. The various generations are described here with the manufacturer's, or other commonly used designations such as "Rekord P I" or "Rekord B". The car was not badged with these additional appellations. Olympia Rekord (1953–1957) The Opel Olympia Rekord was introduced in March 1953 as successor to the Opel Olympia, a pre-World War II design dating back to 1935. The Opel Olympia Rekord was built until 1957 in four different versions. Around 580,000 units were produced. Styling of the 1953–54 sedans resembled scaled-down versions ...

Opel GT
The Opel GT is a front-engine, rear-drive two-seat sports car manufactured and marketed by Opel in two generations — separated by a 34-year hiatus. The first generation Opel GT (1968 –1973) debuted as a styling exercise in 1965 at the Paris and Frankfurt motor shows. The production vehicle used mechanical components from the contemporary Opel Kadett B and two-door hard top bodywork by French contractor Brissonneau & Lotz. The styling of the GT was often cited as similar to the 1968 Chevrolet Corvette which went on sale in September 1967. Opel marketed a second generation ''GT'' (2007-2009) as a rebadged variant of the Saturn Sky two-seater convertible (which was based on the Pontiac Solstice), manufactured in Wilmington, Delaware, USA. In 2016, Opel introduced the ''GT Concept'' at the 2016 Geneva Motor Show as a lightweight, turbocharged, rear-wheel drive two-seater. GT (1968–1973) The Opel GT was equipped with a base 1.1 L OHV inline-four engine, whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automatic Transmission
An automatic transmission (sometimes abbreviated to auto or AT) is a multi-speed transmission used in internal combustion engine-based motor vehicles that does not require any input from the driver to change forward gears under normal driving conditions. It typically includes a transmission, axle, and differential in one integrated assembly, thus technically becoming a transaxle. The most common type of automatic transmission is the hydraulic automatic, which uses a planetary gearset, hydraulic controls, and a torque converter. Other types of automatic transmissions include continuously variable transmissions (CVT), automated manual transmissions (AMT), and dual-clutch transmissions (DCT). An electronic automatic transmission (EAT) may also be called an electronically controlled transmission (ECT), or electronic automatic transaxle (EATX). A hydraulic automatic transmission may also colloquially called a " slushbox" or simply a "torque converter", although the latter term c ...

Torque
In physics and mechanics, torque is the rotational equivalent of linear force. It is also referred to as the moment of force (also abbreviated to moment). It represents the capability of a force to produce change in the rotational motion of the body. The concept originated with the studies by Archimedes of the usage of levers, which is reflected in his famous quote: "''Give me a lever and a place to stand and I will move the Earth''". Just as a linear force is a push or a pull, a torque can be thought of as a twist to an object around a specific axis. Torque is defined as the product of the magnitude of the perpendicular component of the force and the distance of the line of action of a force from the point around which it is being determined. The law of conservation of energy can also be used to understand torque. The symbol for torque is typically \boldsymbol\tau, the lowercase Greek letter ''tau''. When being referred to as moment of force, it is commonly denoted by . In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
