General Motors Rotary Combustion Engine
The General Motors Rotary Combustion Engine (GMRCE) is an internal combustion Wankel engine which uses a rotary design to convert pressure into a rotating motion instead of using reciprocating pistons. In November 1970, GM paid $50 million, ($ in dollars ), for initial licenses to produce their version of the Wankel rotary engine, and GM President Ed Cole initially projected its release in three years. Chevrolet, with impetus from Pete Estes and John DeLorean, as well as Ed Cole worked on the Wankel. Bob Templin was the chief executive in charge of rotary-engine research at the GM Tech Center in Warren, Michigan, but Ed Cole would leave his office in Detroit twice a week for the trip to Warren, taking charge of the program. The engine was initially targeted for an October 1973 introduction as a 1974 Chevrolet Vega option. Its mediocre fuel economy and the ill-timed Arab oil embargo were contributing factors to end the GM rotary program. History of Development ''Popular Scie ...

Gas Mileage
Fuel efficiency is a form of thermal efficiency, meaning the ratio of effort to result of a process that converts chemical potential energy contained in a carrier (fuel) into kinetic energy or work. Overall fuel efficiency may vary per device, which in turn may vary per application, and this spectrum of variance is often illustrated as a continuous energy profile. Non-transportation applications, such as industry, benefit from increased fuel efficiency, especially fossil fuel power plants or industries dealing with combustion, such as ammonia production during the Haber process. In the context of transport, fuel economy is the energy efficiency of a particular vehicle, given as a ratio of distance traveled per unit of fuel consumed. It is dependent on several factors including engine efficiency, transmission design, and tire design. In most countries, using the metric system, fuel economy is stated as "fuel consumption" in liters per 100 kilometers (L/100 km) or kilomete ...

Straight Six
The 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 less cylinders. Until the mid-20th century, the straight-six layout was the most common design for engines with six cylinders. However, V6 engines became more common from the 1960s and by the 2000s most straight-six engines had been replaced by V6 engines. An exception to this trend is BMW which has produced automotive straight-six engines from 1933 to the present day. 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. Straight-six engines are typically produced in displacements ranging from , however engines ranging in size from the Benelli 750 S ...

AMC Pacer
The AMC Pacer is a two-door compact car produced in the United States by American Motors Corporation (AMC) from the 1975 through the 1980 model years. The Pacer was also made in Mexico by Vehículos Automotores Mexicanos (VAM) from 1976 until 1979 and positioned as a premium-priced luxury car. Design work began in 1971. The rounded shape and large glass area were unusual compared with the three-box designs of the era. The Pacer's width is equal to full-sized domestic vehicles at the time, and this unique design feature was promoted by AMC as "the first wide small car." The Pacer was the first modern, mass-produced, U.S. automobile design using the cab forward concept. Reviews upon its introduction used descriptions like "futuristic, bold, and unique." The Pacer featured an aerodynamic "jellybean" styling, numerous innovations such as different door lengths, and was noted "as a space-efficient car, seemingly from the future.".Joe Ligo: , 2013 The Pacer stood out a time when ...

American Motors
American Motors Corporation (AMC; commonly referred to as American Motors) was an American automobile manufacturing company formed by the merger of Nash-Kelvinator Corporation and Hudson Motor Car Company on May 1, 1954. At the time, it was the largest corporate merger in U.S. history. American Motors' most similar competitors were those automakers that held similar annual sales levels such as Studebaker, Packard, Kaiser Motors, and Willys-Overland. Their largest competitors were the Big Three— Ford, General Motors, and Chrysler. American Motors' production line included small cars - the Rambler American which began as the Nash Rambler in 1950, Hornet, Gremlin, and Pacer; intermediate and full-sized cars, including the Ambassador, Rambler Classic, Rebel, and Matador; muscle cars, including the Marlin, AMX and Javelin; and early four-wheel drive variants of the Eagle and the Jeep Wagoneer, the first true crossovers in the U.S. market.

Ralph Nader
Ralph Nader (; born February 27, 1934) is an American political activist, author, lecturer, and attorney noted for his involvement in consumer protection, environmentalism, and government reform causes. The son of Lebanese immigrants to the United States, Nader attended Princeton University and Harvard Law School. He first came to prominence in 1965 with the publication of the bestselling book ''Unsafe at Any Speed'', a highly influential critique of the safety record of American automobile manufacturers. Following the publication of ''Unsafe at Any Speed'', Nader led a group of volunteer law students—dubbed "Nader's Raiders"—in an investigation of the Federal Trade Commission, leading directly to that agency's overhaul and reform. In the 1970s, Nader leveraged his growing popularity to establish a number of advocacy and watchdog groups including the Public Interest Research Group, the Center for Auto Safety, and Public Citizen. Two of Nader's most notable targets were t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chevrolet Corvair
The Chevrolet Corvair is a compact car manufactured by Chevrolet for model years 1960–1969 in two generations. A response to the Volkswagen Beetle, it remains the only American-designed, mass-produced passenger car with a rear-mounted, air-cooled engine. The Corvair was manufactured and marketed in 4-door sedan, 2-door coupe, convertible, 4-door station wagon, passenger van, commercial van, and pickup truck body styles in its first generation (1960–1964) and as a 2-door coupe, convertible or 4-door hardtop in its second (1965–1969) – with a total production of approximately 1.8 million from 1960 until 1969. The name "Corvair" originated as a portmanteau of Corvette and Bel Air, a name first applied in 1954 to a Corvette-based concept with a hardtop fastback-styled roof, part of the Motorama traveling exhibition. When applied to the production models, the "air" part referenced the engine's cooling system. A prominent aspect of the Corvair's legacy derives from c ...

Trochoid
In geometry, a trochoid () is a roulette curve formed by a circle rolling along a line. It is the curve traced out by a point fixed to a circle (where the point may be on, inside, or outside the circle) as it rolls along a straight line. If the point is on the circle, the trochoid is called ''common'' (also known as a cycloid); if the point is inside the circle, the trochoid is ''curtate''; and if the point is outside the circle, the trochoid is ''prolate''. The word "trochoid" was coined by Gilles de Roberval. Basic description As a circle of radius rolls without slipping along a line , the center moves parallel to , and every other point in the rotating plane rigidly attached to the circle traces the curve called the trochoid. Let . Parametric equations of the trochoid for which is the -axis are :\begin & x = a\theta - b \sin \theta \\ & y = a - b \cos \theta \end where is the variable angle through which the circle rolls.

Environmental Protection Agency
A biophysical environment is a biotic and abiotic surrounding of an organism or population, and consequently includes the factors that have an influence in their survival, development, and evolution. A biophysical environment can vary in scale from microscopic to global in extent. It can also be subdivided according to its attributes. Examples include the marine environment, the atmospheric environment and the terrestrial environment. The number of biophysical environments is countless, given that each living organism has its own environment. The term ''environment'' can refer to a singular global environment in relation to humanity, or a local biophysical environment, e.g. the UK's Environment Agency. Life-environment interaction All life that has survived must have adapted to the conditions of its environment. Temperature, light, humidity, soil nutrients, etc., all influence the species within an environment. However, life in turn modifies, in various forms, its conditions ...
