Quad-4
Quad 4 is the name of a family of principally DOHC inline four-cylinder engines produced by General Motors' Oldsmobile division between 1987 and 2002; a single SOHC version was built between 1992 and 1994. Its name was derived from the engine's four-valve, four-cylinder layout. Introduced with a displacement of , the engine was a modern design for its time, using a cast-iron block and an aluminum head. Even though belts were more popular for this purpose on OHC engines at the time, chains were used to time the camshafts to the crankshaft. The water pump is also driven by the timing chain. The Quad 4 was the first wholly domestic regular production DOHC four-cylinder engine designed and built by GM; the only prior DOHC four-cylinder engine offered by GM was the Cosworth Vega, which featured a DOHC head designed by Cosworth in England. In addition to the DOHC versions, there was also both a short-lived SOHC variant, the "Quad OHC", available from 1992 to 1994, and the Twin C ...

GM Ecotec Engine
The GM Ecotec engine, also known by its codename L850, is a family of all-aluminium inline-four engines, displacing between 1.4 and 2.5 litres. While these engines were based on the GM Family II engine, the architecture was substantially re-engineered for the new Ecotec application produced since 2000. This engine family replaced the GM Family II engine, the GM 122 engine, the Saab H engine, and the Quad 4 engine. It is manufactured in multiple locations, to include Spring Hill Manufacturing, in Spring Hill, Tennessee while the engine block and cylinder heads are cast at Saginaw Metal Casting Operations in Saginaw, Michigan. Generation I The 'Ecotec' name was adopted in 1994 for the new generation of Family II engines (2000 in North America) . The name was already used for the Opel GM Family II engine, Family 1 and Family 0 ranges. GM intended this new Ecotec to become its global 4-cylinder, and it has already fully replaced their OHV I4 line. The Ecotec engine is a DOHC 4-val ...

Pontiac Grand Am
The Pontiac Grand Am is a mid-size car and later a compact car that was produced by Pontiac. The Grand Am had two separate three-year runs in the 1970s: from 1973 to 1975, and again from 1978 to 1980. It was based on the GM A platform. Production of the intermediate sized Grand Am was canceled in 1980 when it was replaced by the Pontiac 6000. The compact-sized Grand Am was reintroduced in 1985 when it replaced the Pontiac Phoenix. It became Pontiac's best selling car and was later replaced by the Pontiac G6, so named as it was intended to be the 6th generation of the Grand Am. All 1973–1975 Grand Ams were built in Pontiac, Michigan at Pontiac's main assembly plant. The 1978-1980 Grand Ams were built in Pontiac, Michigan at Pontiac's main assembly plant and in Atlanta, Georgia at GMAD Lakewood. All Grand Ams between 1985 and 2005 were built in Lansing, Michigan at the Lansing Car Assembly. 1973–1975 The history of Grand Am begins with Pontiac executives noting incursion into ...

Lansing Engine Plant
Lansing Engine Plant was a General Motors automotive engine plant located in Delta Township, Michigan Delta Charter Township, officially known as the Charter Township of Delta and commonly known as simply Delta Township, is a charter township of Eaton County in the U.S. state of Michigan. As of the 2010 census, it had a population of 32,408 maki .... Constructed in 1981, it was originally constructed to create diesel counterparts of GM's gasoline engines, though, by the next year, GM had abandoned the project. By 1987, the plant was producing the Quad-4 engine, and in 2002 the EcoTec engine, but was closed that same year. GM sold the plant to Ashley Capital in 2005 who then leased it out to auto parts supplier Ryder Logistics.

Multi-valve
In automotive engineering a multi-valve or multivalve engine is one where each cylinder has more than two valves. A multi-valve engine has better breathing and may be able to operate at higher revolutions per minute (RPM) than a two-valve engine, delivering more power. Multi-valve rationale Multi-valve engine design A multi-valve engine design has three, four, or five valves per cylinder to achieve improved performance. Any four-stroke internal combustion engine needs at least two valves per cylinder: one for ''intake'' of air (and often fuel), and another for ''exhaust'' of combustion gases. Adding more valves increases valve area and improves the flow of intake and exhaust gases, thereby enhancing combustion, volumetric efficiency, and power output. Multi-valve geometry allows the spark plug to be ideally located within the combustion chamber for optimal flame propagation. Multi-valve engines tend to have smaller valves that have lower reciprocating mass, which can red ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oldsmobile Cutlass Calais
The Oldsmobile Calais is a compact car that was manufactured and marketed by Oldsmobile from 1985 through 1991, superseding the Oldsmobile Omega and named after the city of Calais, France. Renamed the Cutlass Calais for 1988, and briefly available in 1987 as the limited edition GMO Quad 4, the Calais shared the GM N platform with the Pontiac Grand Am and the Buick Skylark/Buick Somerset — and was superseded by the Oldsmobile Achieva in 1992. The first production model ( VIN 1G3NT27UXFM200001), was a white Calais Supreme two-door with a gray velour interior. Equipped with an automatic transmission and the 92 horsepower, 151 CID pushrod four-cylinder engine (also known as GM's "Iron Duke" Tech-IV), this particular model was outfitted with nearly every available option, including wire wheel covers. While this front-wheel drive car is maintained by the R.E. Olds Transportation Museum in Lansing, Michigan, it was one of more than 700 vehicles that made up the GM Heritage Collec ...

Cosworth Vega
The Chevrolet Cosworth Vega is a subcompact four-passenger automobile produced by Chevrolet for the 1975 and 1976 model years. It is a limited-production version of the Chevrolet Vega, with higher performance. Chevrolet developed the car's all-aluminum inline-four engine, and British company Cosworth Engineering designed the DOHC cylinder head. 5,000 engines were built. 3,508 cars were made. They were priced nearly double that of a base Vega and only $900 below the 1975 Chevrolet Corvette. History Racing origin Known at Cosworth Engineering as Project EA, a Cosworth racing engine based on the Vega aluminum block produced a reported and powered Chevron and Lola race cars to wins in the 2-liter class in their first outings. The ZO9 Cosworth Vega engine is a de-tuned version. Bore, stroke and valve sizes are identical but it lacks the EA engine’s dry sump lubricating system (unnecessary in a street use car), has a lower compression ratio and different valve timing, and uses B ...

Model Year
The model year (sometimes abbreviated "MY") is a method of describing the version of a product which has been produced over multiple years. The model year may or may not be the same as the calendar year in which the product was manufactured. Automobiles United States and Canada Automobiles in the United States and Canada are identified and regulated by model year, whereas other markets use production date (month/year) to identify specific vehicles, and model codes in place of the "year" (model year) in the North American make-model-year identifier. In technical documents generated within the auto industry and its regulating agencies such as the U.S. National Highway Traffic Safety Administration and United States Environmental Protection Agency and Transport Canada and Environment Canada, the letters "MY" often precede the year (as in "MY2019" or "MY93"). Even without this prefix, however, in the North American context it is usually the model year rather than the vehicle' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chevrolet
Chevrolet ( ), colloquially referred to as Chevy and formally the Chevrolet Motor Division of General Motors Company, is an American automobile division of the American manufacturer General Motors (GM). Louis Chevrolet (1878–1941) 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's second ousting in 1919, Alfred Sloan, with his maxim "a car for every purse and purpose", would pick the Chevrolet brand to become the volume leader in the General Motors family, selling mainstream vehicles to compete with Henry Ford's Model T in 1919 and overtaking Ford as the best-selling car in the United States by 1929 with the Chevrolet International. Chevrolet-branded vehicles are sold in most autom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
