Chevrolet
Chevrolet ( ) is an American automobile division of the manufacturer General Motors (GM). In North America, Chevrolet produces and sells a wide range of vehicles, from subcompact automobiles to medium-duty commercial trucks. Due to the prominence and name recognition of Chevrolet as one of General Motors' global marques, "Chevrolet" or its affectionate nickname 'Chevy' or is used at times as a synonym for General Motors or its products, one example being the GM LS1 engine, commonly known by the name or a variant thereof of its progenitor, the Chevrolet small-block engine. Louis Chevrolet (1878–1941), Arthur Chevrolet (1884–1946) and ousted General Motors founder William C. Durant (1861–1947) started the company on November 3, 1911 as the Chevrolet Motor Car Company. Durant used the Chevrolet Motor Car Company to acquire a controlling stake in General Motors with a reverse merger occurring on May 2, 1918, and propelled himself back to the GM presidency. After Durant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chevrolet Corvette (C3)
The Chevrolet Corvette (C3) is the third generation of the Corvette sports car that was produced from 1967 until 1982 by Chevrolet for the 1968 to 1982 model years. Engines and chassis components were mostly carried over from the previous generation, but the body and interior were new. It set new sales records with 53,807 produced for the 1979 model year. The C3 was the second Corvette to carry the Stingray name, though only for the 1969–76 model years. This time it was a single word as opposed to Sting Ray as used for the 1963–67 C2 generation. The name was then retired until 2014 when it returned with the release of the C7. The most expensive Corvette C3 to sell in history was a 1969 L88 Lightweight, one of only four lightweight L88s to be produced. It was sold by Barrett-Jackson in January 2014 for $2,860,000 (£1,728,941). History Mako Shark II Concept The Corvette C3 was patterned after the Mako Shark II designed by Larry Shinoda.

Electronic Ignition
Ignition systems are used by heat engines to initiate combustion by igniting the fuel-air mixture. In a spark ignition versions of the internal combustion engine (such as petrol engines), the ignition system creates a spark to ignite the fuel-air mixture just before each ''combustion'' stroke. Gas turbine engines and rocket engines normally use an ignition system only during start-up. Diesel engines use ''compression ignition'' to ignite the fuel-air mixture using the heat of compression and therefore do not use an ignition system. They usually have glowplugs that preheat the combustion chamber to aid starting in cold weather. Early cars used ignition magneto and trembler coil systems, which were superseded by Distributor-based systems (first used in 1912). Electronic ignition systems (first used in 1968) became common towards the end of the 20th century, with coil-on-plug versions of these systems becoming widespread since the 1990s. Magneto and mechanical systems Ignit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrocarbon
In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. Hydrocarbons are examples of group 14 hydrides. Hydrocarbons are generally colourless and Hydrophobe, hydrophobic; their odor is usually faint, and may be similar to that of gasoline or Naphtha, lighter fluid. They occur in a diverse range of molecular structures and phases: they can be gases (such as methane and propane), liquids (such as hexane and benzene), low melting solids (such as paraffin wax and naphthalene) or polymers (such as polyethylene and polystyrene). In the fossil fuel industries, ''hydrocarbon'' refers to naturally occurring petroleum, natural gas and coal, or their hydrocarbon derivatives and purified forms. Combustion of hydrocarbons is the main source of the world's energy. Petroleum is the dominant raw-material source for organic commodity chemicals such as solvents and polymers. Most anthropogenic (human-generated) emissions of greenhouse gases are eithe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torque Curve
In physics and mechanics, torque is the rotational analogue of linear force. It is also referred to as the moment of force (also abbreviated to moment). The symbol for torque is typically \boldsymbol\tau, the lowercase Greek alphabet, Greek letter ''tau''. When being referred to as moment (physics), moment of force, it is commonly denoted by . Just as a linear force is a push or a pull applied to a body, a torque can be thought of as a twist applied to an object with respect to a chosen point; for example, driving a screw uses torque to force it into an object, which is applied by the screwdriver rotating around its Axis of rotation, axis to the List of screw drives, drives on the head. Historical terminology The term ''torque'' (from Latin , 'to twist') is said to have been suggested by James Thomson (engineer), James Thomson and appeared in print in April, 1884.

Exhaust Manifold
In automotive engineering, an exhaust manifold collects the exhaust gases from multiple cylinders into one pipe. The word ''manifold'' comes from the Old English word ''manigfeald'' (from the Anglo-Saxon ''manig'' anyand ''feald'' old and refers to the folding together of multiple inputs and outputs (in contrast, an inlet or intake manifold ''supplies'' air ''to'' the cylinders). Exhaust manifolds are generally simple cast iron or stainless steel units which collect engine exhaust gas from multiple cylinders and deliver it to the exhaust pipe. For many engines, there are aftermarket tubular exhaust manifolds known as headers in American English, as extractor manifolds in British and Australian English, and simply as "tubular manifolds" in British English. These consist of individual exhaust headpipes for each cylinder, which then usually converge into one tube called a collector. Headers that do not have collectors are called zoomie headers. The most common types of afterm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

United States Environmental Protection Agency
The Environmental Protection Agency (EPA) is an independent agency of the United States government tasked with environmental protection matters. President Richard Nixon proposed the establishment of EPA on July 9, 1970; it began operation on December 2, 1970, after Nixon signed an executive order. The order establishing the EPA was ratified by committee hearings in the House and Senate. The agency is led by its administrator, who is appointed by the president and approved by the Senate. The current administrator is Lee Zeldin. The EPA is not a Cabinet department, but the administrator is normally given cabinet rank. The EPA has its headquarters in Washington, D.C. There are regional offices for each of the agency's ten regions, as well as 27 laboratories around the country. The agency conducts environmental assessment, research, and education. It has the responsibility of maintaining and enforcing national standards under a variety of environmental laws, in consultat ...

Ed Cole
Edward Nicholas Cole (September 17, 1909 – May 2, 1977) was an American inventor, automotive engineer and executive, widely known for leading critical projects for General Motors, including development of the Chevrolet Corvair and Chevrolet Vega; developing GM's Small Block V8 and its rotary engine, championing the catalytic converter to migrate cars from leaded gasoline, and advocating for air bags. He was President of General Motors from 1967 through 1974. Background Cole was born in 1909 in Marne, Michigan, to Franklin Benjamin Cole (1874-1944) and Lucy Blasen Cole (1879-1962). Raised on a dairy farm, as a youth he designed, built, and sold homemade radio sets, and as a teenager became a field representative for a tractor manufacturer. He wanted to be a lawyer, but landed a part-time job in an auto parts store while attending Grand Rapids Community College. In 1930, Cole enrolled in the General Motors Institute, where he was selected by GM for an engineering assignmen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carburetor
A carburetor (also spelled carburettor or carburetter) is a device used by a gasoline internal combustion engine to control and mix air and fuel entering the engine. The primary method of adding fuel to the intake air is through the Venturi effect or Bernoulli's principle or with a Pitot tube in the main metering circuit, though various other components are also used to provide extra fuel or air in specific circumstances. Since the 1990s, carburetors have been largely replaced by fuel injection for cars and trucks, but carburetors are still used by some small engines (e.g. lawnmowers, generators, and concrete mixers) and motorcycles. In addition, they are still widely used on piston-engine–driven aircraft. Diesel engines have always used fuel injection instead of carburetors, as the compression-based combustion of diesel requires the greater precision and pressure of fuel injection. Etymology The term ''carburetor'' is derived from the verb ''carburet'', which means "to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuel Injection
Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of a fuel injector. This article focuses on fuel injection in reciprocating piston and Wankel rotary engines. All compression-ignition engines (e.g. diesel engines), and many spark-ignition engines (i.e. petrol (gasoline) engines, such as Otto or Wankel), use fuel injection of one kind or another. Mass-produced diesel engines for passenger cars (such as the Mercedes-Benz OM 138) became available in the late 1930s and early 1940s, being the first fuel-injected engines for passenger car use. In passenger car petrol engines, fuel injection was introduced in the early 1950s and gradually gained prevalence until it had largely replaced carburetors by the early 1990s. The primary difference between carburetion and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while carburetion relies on suction crea ...

John DeLorean
John Zachary DeLorean ( ; January 6, 1925 – March 19, 2005) was an American engineer, inventor, and executive in the U.S. automobile industry. He is widely known as founder of the DeLorean Motor Company, as well as for his work at General Motors. DeLorean managed the development of several vehicles throughout his career, including the Pontiac GTO, Pontiac Firebird, Pontiac Grand Prix, Chevrolet Cosworth Vega, and DMC DeLorean, which was featured in the 1985 film ''Back to the Future''. He was the youngest division chief in General Motors history, then left to start the DeLorean Motor Company (DMC) in 1973. Production delays meant that DMC's first car did not reach the consumer market until 1981, when a depressed buying market was compounded by lukewarm reviews from critics and the public. After a year, the DeLorean had failed to recover its $175 million investment costs, unsold cars accumulated, and the company was in financial trouble. In October 1982, DeLorean was charged wit ...
