Chevrolet 2300 Engine
The 2300 is a inline-four engine produced by the Chevrolet division of General Motors for the 1971 to 1977 model years of the Chevrolet Vega and Chevrolet Monza. It featured a die-cast aluminum alloy cylinder block. The high-tech block features an alloy with 17 percent silicon. During the machining process, the cylinders were etched leaving the pure silicon particles exposed providing the piston wear surface, eliminating the need for iron cylinder liners. The block has cast iron main caps and a cast iron crankshaft. The engine's cylinder head is cast iron for lower cost, structural integrity and longer camshaft Bearing (mechanical), bearing life. The valvetrain features a direct-acting single overhead camshaft design. retrieved on 18 December 2008. The engine block and cylinder heads were ...

GM Iron Duke Engine
The Iron Duke engine (also called 151, 2500, Pontiac 2.5, and Tech IV) is a Straight-4 piston engine built by the Pontiac Motor Division of General Motors from 1977 to 1993. Thereafter GM's 2.2 L OHV 4-cylinder replaced it across the entire lineup of vehicles that offered it. Although its original purpose was to serve as Pontiac's new economy car engine, it was later adapted for use in a wide variety of applications across GM's lineup in the 1980s. Development At the time of the 1973 oil crisis the only engines Pontiac built were , , and versions of their V8 engine. Recognizing that future products would need to be smaller and more fuel-efficient, Pontiac engineers were tasked with developing a new engine that would be suitable for these future products. The engineers considered developing smaller displacement versions of the existing V8, a V6 derived from the V8, a V4 derived from the V8, and an inline-four derived from one of the cylinder banks of the V8 (in the s ...

Silicon
Silicon is a chemical element with the symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic luster, and is a tetravalent metalloid and semiconductor. It is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, lead, and flerovium are below it. It is relatively unreactive. Because of its high chemical affinity for oxygen, it was not until 1823 that Jöns Jakob Berzelius was first able to prepare it and characterize it in pure form. Its oxides form a family of anions known as silicates. Its melting and boiling points of 1414 °C and 3265 °C, respectively, are the second highest among all the metalloids and nonmetals, being surpassed only by boron. Silicon is the eighth most common element in the universe by mass, but very rarely occurs as the pure element in the Earth's crust. It is widely distributed in space in cosmic dusts, planetoids, and planets as various forms of silicon dioxide ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DOHC
An overhead camshaft (OHC) engine is a piston engine where the camshaft is located in the cylinder head above the combustion chamber. This contrasts with earlier overhead valve engines (OHV), where the camshaft is located below the combustion chamber in the engine block. ''Single overhead camshaft'' (SOHC) engines have one camshaft per bank of cylinders. ''Dual overhead camshaft'' (DOHC, also known as "twin-cam".) engines have two camshafts per bank. The first production car to use a DOHC engine was built in 1910. Use of DOHC engines slowly increased from the 1940s, leading to many automobiles by the early 2000s using DOHC engines. Design In an OHC engine, the camshaft is located at the top of the engine, above the combustion chamber. This contrasts the earlier overhead valve engine (OHV) and flathead engine configurations, where the camshaft is located down in the engine block. The valves in both OHC and OHV engines are located above the combustion chamber; however an OHV ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cosworth
Cosworth is a British automotive engineering company founded in London in 1958, specialising in high-performance internal combustion engines, powertrain, and electronics for automobile racing (motorsport) and mainstream automotive industries. Cosworth is based in Northampton, England, with American facilities in Indianapolis and Mooresville, North Carolina.

Oldsmobile Starfire
The Oldsmobile Starfire is an automobile nameplate used by Oldsmobile, produced in three non-contiguous generations beginning in 1954. The Starfire nameplate made its debut as a convertible concept car in 1953 followed with the 1954–1956 Ninety-Eight series convertibles that shared a "halo status" with the Buick Skylark and Cadillac Eldorado. For 1957 only, all Ninety-Eight series models were named "98 Starfire ". Oldsmobile during this time period was one of the most popular brands selling, and the company saw an opportunity to benefit from the Space Race of the 1960s. The "rocket" terminology was already a benefit with their Rocket V8. After a two-year hiatus the Starfire name returned for 1961 as separate model, offered in a single convertible body style. Intended to compete in the growing personal luxury car market, from 1961 to 1965 the Starfire Convertible was the highest-priced model offered by Oldsmobile. While it shared most of its sheet metal with other full-si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pontiac Sunbird
The Pontiac Sunbird (also known as the Pontiac J2000 and Pontiac 2000) is a model line that was manufactured and marketed by Pontiac from the 1976 to the 1994 model years. Loosely deriving its name from the Pontiac Firebird, the Sunbird was introduced as the eventual replacement for the Pontiac Astre, replacing it entirely in 1978 as the smallest Pontiac (the later T1000 was slotted below it in size). The first generation of the Sunbird used the subcompact GM H platform. Serving as the Pontiac counterpart of the Chevrolet Monza, the Sunbird was offered as a two-door notchback coupé and three-door hatchback and station wagon. The model was manufactured alongside the Monza, Buick Skyhawk, and Oldsmobile Starfire at Lordstown Assembly (Lordstown, Ohio) and Sainte-Thérèse Assembly (Sainte-Thérèse, Quebec). The second generation of the Sunbird used the compact GM J platform. Serving as the Pontiac counterpart of the Chevrolet Cavalier, the Sunbird was marketed at various ...

H-body
The H Platform, or H-body, name has been used twice by General Motors. The 1970s H-body was an inexpensive rear-wheel drive compact automobile platform from the 1970s, used for the Chevrolet Vega and Monza and their Buick, Oldsmobile, and Pontiac derivatives. The 1980s H-body was a front-wheel drive full-size car platform, and was the basis for GM's second generation downsized full-size cars, which included the Buick LeSabre, Oldsmobile 88, and Pontiac Bonneville. * 1971–1980 GM H platform (RWD) compact cars * 1986–2005 GM H platform (FWD) full-size car Full-size car—also known as large car—is a vehicle size class which originated in the United States and is used for cars larger than mid-size cars, it is the largest size class for cars.

Pontiac Astre
The Pontiac Astre is a subcompact automobile that was marketed by Pontiac as a rebadged variant of the Chevrolet Vega. Initially marketed in Canada for model years 1973–1974, the Astre debuted in the U.S. for the 1975 model year, competing with other domestic and foreign subcompacts that included the Mercury Bobcat, Volkswagen Rabbit, and Toyota Corolla. Built on the H-body platform, the car was available in hatchback, notchback, wagon, and panel delivery body styles. The Astre shared the aluminum-block 2.3 liter inline-four engine with the Vega through 1976, while the final 1977 models used Pontiac's all-iron 2.5 liter inline-four engine. The Astre was cancelled with the Vega at the end of the 1977 model year, although the wagon continued for 1978 and 1979, rebadged as part of the Pontiac Sunbird line. The word ''" astre"'' is Catalan for "star", a shared naming convention for the Vega. Design In 1968 GM chairman James Roche announced that General Motors would p ...

Bearing (mechanical)
A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts. The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may ''prevent'' a motion by controlling the vectors of normal forces that bear on the moving parts. Most bearings facilitate the desired motion by minimizing friction. Bearings are classified broadly according to the type of operation, the motions allowed, or to the directions of the loads (forces) applied to the parts. Rotary bearings hold rotating components such as shafts or axles within mechanical systems, and transfer axial and radial loads from the source of the load to the structure supporting it. The simplest form of bearing, the ''plain bearing'', consists of a shaft rotating in a hole. Lubrication is used to reduce friction. In the ''ball bearing'' and ''roller bearing'', to reduce sliding ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
