Oldsmobile Series 20
The Series 20 was an automobile produced by Oldsmobile Division of General Motors in 1909. When the Oldsmobile Company joined General Motors in 1908, the Series 20 was one of the first examples of platform sharing that became GM's most notable business model, as it was derived from the previously established Buick brand from the Buick Model B. The Series 20 effectively replaced the Model F, also known as the Curved-Dash Oldsmobile, when it was discontinued when GM assumed operations, and was replaced by the 1914 Oldsmobile Model 42 "Baby Olds". It was the entry-level vehicle below the Oldsmobile Model A and the luxury sedan Oldsmobile Model Z. It was the first Oldsmobile to use numbers to identify the product, a tradition that would last until the company concluded operations in 2004. History The Series 20 was equipped with a side-valve, in-line 2,704 cc four-cylinder engine developing 22 bhp. The engine was installed in the front, driving the rear wheels through a transmis ...

Oldsmobile
Oldsmobile or formally the Oldsmobile Division of General Motors was a brand of American automobiles, produced for most of its existence by General Motors. Originally established as "Olds Motor Vehicle Company" by Ransom E. Olds in 1897, it produced over 35 million vehicles, including at least 14 million built at its Lansing, Michigan factory alone. During its time as a division of General Motors, Oldsmobile slotted into the middle of GM's five (passenger car) divisions (above Chevrolet and Pontiac, but below Buick and Cadillac), and was noted for several groundbreaking technologies and designs. Oldsmobile's sales peaked at over one million annually from 1983 to 1986, but by the 1990s the division faced growing competition from premium import brands, and sales steadily declined. When it shut down in 2004, Oldsmobile was the oldest surviving American automobile marque, and one of the oldest in the world, after Mercedes-Benz, Peugeot, Renault, Fiat, Opel, Autocar and Tatra (i ...

Buick Model B
The Buick Model B was Buick's first model as an independent company, later becoming part of General Motors in 1908. It was built in Jackson, Michigan. A model B was exhibited in 1905 at the New York Auto Show as a promotion of the model C which would be the same. William C. Durant introduced the car himself at the exhibit, and took new car orders at the car show, raising sales from 37 cars in 1904 to 750 in 1905. It had a 2-cylinder, horizontally opposed engine – the world's first production OHV (overhead valve) engine – installed lengthwise within the frame, had a planetary transmission, with a cone clutch and two forward speeds and one reverse gear. The engine was rated at 21 bhp. In later years, it was renamed as improvements were made. The chassis was shared later with the Oldsmobile Model 20 The Series 20 was an automobile produced by Oldsmobile Division of General Motors in 1909.

Oldsmobile Curved Dash
__NOTOC__ The gasoline-powered Oldsmobile Model R, also known as the Curved Dash Oldsmobile, is credited as being the first mass-produced automobile, meaning that it was built on an assembly line using interchangeable parts. It was introduced by the Oldsmobile company in 1901 and produced through 1903; 425 were produced the first year, 2,500 in 1902, and over 19,000 were built in all. When General Motors assumed operations from Ransom E. Olds on November 12, 1908, GM introduced the Oldsmobile Model 20, which was the 1908 Buick Model 10 with a stretched wheelbase and minor exterior changes. It was a runabout model, could seat two passengers, and sold for US$650 ($ in dollars). While competitive, due to high volume, and priced below the US$850 two-seat Ford Model C "Doctor's Car", it was more expensive than the Western 1905 Gale Model A roadster at US$500. The Black sold for $375, and the Success for US$250. It was built as a city car for short distance driving, while the larger ...

Oldsmobile Model 42
The Model 42 was an entry-level four seat passenger car produced by GM's Oldsmobile Division in 1914, offered as a replacement to the Oldsmobile Curved Dash runabout (car), runabout when it was discontinued in 1908, and was the junior platform to the Oldsmobile Six introduced in 1913. GM had acquired Elmore Manufacturing Company, Oldsmobile and Oakland Motor Car Company in 1908 and Cartercar and Rainier Motor Car Company in 1909 as their entry-level models, and Oldsmobile products were being repositioned in their new hierarchy as GM began to consolidate operations after William C. Durant, William Durant had left. It was replaced by the Oldsmobile Model 43, Model 43 and shared a platform with the Buick Model 10. The Oldsmobile Model R Curved Dash competed with the Chevrolet Series F while Chevrolet was still independent from GM, and in 1908 the Ford Model T was also introduced. It was also known as the "''Baby Olds''" as it was smaller than the mid-level Oldsmobile Series 28, Olds ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oldsmobile Model Z
The Oldsmobile Model Z was the company's first top-level passenger car produced under the Oldsmobile brand before they became a division of General Motors in 1908. The Model Z was created and engineered after Mr. Olds left the company but before they became a division, the same year the car was introduced. It was the senior model to the mid-level Oldsmobile Model M, and the entry-level, Buick engineered Oldsmobile Model 20. It was upgraded to become the Oldsmobile Limited.Clymer, Floyd. ''Treasury of Early American Automobiles, 1877-1925'' (New York: Bonanza Books, 1950) History The Model Z was the first Oldsmobile to introduce a flathead engine with six cylinders, displacing developing 48 bhp. The engine was installed in the front, driving the rear wheels through a transmission shaft. The gearbox had three forward gears, with the gearshift lever positioned to the right of the driver.

Multi-cylinder Engine
The engine configuration describes the fundamental operating principles by which internal combustion engines are categorized. Piston engines are often categorized by their cylinder layout, valves and camshafts. Wankel engines are often categorized by the number of rotors present. Gas turbine engines are often categorized into turbojets, turbofans, turboprops and turboshafts. Piston engines Piston engines are usually designed with the cylinders in lines parallel to the crankshaft. It is called a straight engine (or 'inline engine') when the cylinders arranged in a single line. Where the cylinders are arranged in two or more lines (such as in V engines or flat engines), each line of cylinders is referred to as a 'cylinder bank'. The angle between cylinder banks is called the 'bank angle'. Engines with multiple banks are shorter than straight engines and can be designed to cancel out the unbalanced forces from each bank, in order to reduce the vibration. Most engines with fou ...

Transmission (mechanics)
Propulsion transmission is the mode of transmitting and controlling propulsion power of a machine. The term ''transmission'' properly refers to the whole drivetrain, including clutch, gearbox, prop shaft (for rear-wheel drive vehicles), differential, and final drive shafts. In the United States the term is sometimes used in casual speech to refer more specifically to the gearbox alone, and detailed usage differs. The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in the process. Transmissions are also used on pedal bicycles, fixed machines, and where different rotational speeds and torques are adapted. Often, a transmission has multiple gear ratios (or simply "gears") with the ability to switch between them as the speed varies. This switching may be done manually (by the operator) or automatically (by a control unit). Directional (forward and reverse) control may also be provided. Single-ratio transmissions also exist, which simply cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crankshaft
A crankshaft is a mechanical component used in a piston engine to convert the reciprocating motion into rotational motion. The crankshaft is a rotating shaft containing one or more crankpins, that are driven by the pistons via the connecting rods. The crankpins are also called ''rod bearing journals'', and they rotate within the "big end" of the connecting rods. Most modern crankshafts are located in the engine block. They are made from steel or cast iron, using either a forging, casting or machining process. Design The crankshaft located within the engine block, held in place via main bearings which allow the crankshaft to rotate within the block. The up-down motion of each piston is transferred to the crankshaft via connecting rods. A flywheel is often attached to one end of the crankshaft, in order to smoothen the power delivery and reduce vibration. A crankshaft is subjected to enormous stresses, in some cases more than per cylinder. Crankshafts for single-cylin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drum Brake
A drum brake is a brake that uses friction caused by a set of shoes or pads that press outward against a rotating cylinder-shaped part called a brake drum. The term ''drum brake'' usually means a brake in which shoes press on the inner surface of the drum. When shoes press on the outside of the drum, it is usually called a '' clasp brake''. Where the drum is pinched between two shoes, similar to a conventional disc brake, it is sometimes called a ''pinch drum brake'', though such brakes are relatively rare. A related type called a band brake uses a flexible belt or "band" wrapping around the outside of a drum. History The modern automobile drum brake was first used in a car made by Maybach in 1900, although the principle was only later patented in 1902 by Louis Renault. He used woven asbestos lining for the drum brake lining, as no alternative dissipated heat like the asbestos lining, though Maybach had used a less sophisticated drum brake. In the first drum brakes, levers a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acetylene
Acetylene (systematic name: ethyne) is the chemical compound with the formula and structure . It is a hydrocarbon and the simplest alkyne. This colorless gas is widely used as a fuel and a chemical building block. It is unstable in its pure form and thus is usually handled as a solution. Pure acetylene is odorless, but commercial grades usually have a marked odor due to impurities such as divinyl sulfide and phosphine.Compressed Gas Association (1995Material Safety and Data Sheet – Acetylene As an alkyne, acetylene is unsaturated because its two carbon atoms are bonded together in a triple bond. The carbon–carbon triple bond places all four atoms in the same straight line, with CCH bond angles of 180°. Discovery Acetylene was discovered in 1836 by Edmund Davy, who identified it as a "new carburet of hydrogen". It was an accidental discovery while attempting to isolate potassium metal. By heating potassium carbonate with carbon at very high temperatures, he produced a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
