Z22SE
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 General Motors 122 engine, 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, GM Family 1 engine, Family 1 and GM Family 0 engine, Family 0 ranges. GM intended this new Ecotec to become its global 4-cylinder, and it has already full ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inline-four Engine
A straight-four engine (also called an inline-four) is a four-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. The vast majority of automotive four-cylinder engines use a straight-four layout (with the exceptions of the flat-four engines produced by Subaru and Porsche) and the layout is also very common in motorcycles and other machinery. Therefore the term "four-cylinder engine" is usually synonymous with straight-four engines. When a straight-four engine is installed at an inclined angle (instead of with the cylinders oriented vertically), it is sometimes called a slant-four. Between 2005 and 2008, the proportion of new vehicles sold in the United States with four-cylinder engines rose from 30% to 47%. By the 2020 model year, the share for light-duty vehicles had risen to 59%. Design A four-stroke straight-four engine always has a cylinder on its power stroke, unlike engines with fewer cylinders where there is no power stroke occu ...

Multivalve
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 redu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbocharger
In an internal combustion engine, a turbocharger (often called a turbo) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake gas, forcing more air into the engine in order to produce more power for a given displacement. The current categorisation is that a turbocharger is powered by the kinetic energy of the exhaust gasses, whereas a supercharger is mechanically powered (usually by a belt from the engine's crankshaft). However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. History Prior to the invention of the turbocharger, |

Tonawanda (town), New York
Tonawanda (formally the Town of Tonawanda) is a town in Erie County, New York, United States. As of the 2020 census, the town had a population of 72,636. The town is at the north border of the county and is the northern inner ring suburb of Buffalo. It is sometimes referred to, along with its constituent village of Kenmore, as "Ken-Ton". The town was established in 1836, and up to 1903 it included what is now the city of Tonawanda. History This area was under French control from the 17th century until it was ceded to the British after the French and Indian War. The first European settlers arrived around 1805. Rapid growth began after the construction of the Erie Canal, completed in 1825. Tonawanda occupies the northwest corner of Erie County and is bounded on the north by the Erie Canal, which here follows Tonawanda Creek. The town of Tonawanda was established in 1836, by separation from the town of Buffalo (now part of the city of Buffalo). At that time it included land tha ...

Balance Shaft
Balance shafts are used in piston engines to reduce vibration by cancelling out unbalanced dynamic forces. The counter balance shafts have eccentric weights and rotate in opposite direction to each other, which generates a net vertical force. The balance shaft was invented and patented by British engineer Frederick W. Lanchester in 1907. It is most commonly used in inline-four and V6 engines used in automobiles and motorcycles. Overview The operating principle of a balance shaft system is that two shafts carrying identical eccentric weights rotate in opposite directions at twice the engine speed. The phasing of the shafts is such that the centrifugal forces produced by the weights cancel the vertical second-order forces (at twice the engine RPM) produced by the engine. The horizontal forces produced by the balance shafts are equal and opposite, and so cancel each other. The balance shafts do not reduce the vibrations experienced by the crankshaft.

Iron
Iron () is a chemical element with symbol Fe (from la, ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, right in front of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. In its metallic state, iron is rare in the Earth's crust, limited mainly to deposition by meteorites. Iron ores, by contrast, are among the most abundant in the Earth's crust, although extracting usable metal from them requires kilns or furnaces capable of reaching or higher, about higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BCE and the use of iron tools and weapons began to displace copper alloys, in some regions, only around 1200 BCE. That event is considered the transition from the Bronze Age to the Iron A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminium
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity tow ...

Saab Automobile
Saab Automobile AB () is a defunct automotive industry, car manufacturer that was founded in Sweden in 1945 when its parent company, Saab AB, began a project to design a small automobile. The first production model, the Saab 92, was launched in 1949. In 1968 the parent company merged with Scania-Vabis, and ten years later the Saab 900 was launched, in time becoming Saab's best-selling model. In the mid-1980s the new Saab 9000 model also appeared. In 1989, the automobile division of Saab-Scania was restructured into an independent company, Saab Automobile AB. The American manufacturer General Motors (GM) took 50 percent ownership. Two well-known models to come out of this period were the Saab 9-3 and the Saab 9-5. Then in 2000, GM exercised its option to acquire the remaining 50 percent. In 2010 GM sold Saab Automobile AB to the Dutch automobile manufacturer Spyker Cars N.V. After many years establishing a sound engineering reputation and ultimately a luxury car, luxury price t ...
