Straight-eight
The straight-eight engine (also referred to as an inline-eight engine; abbreviated I8 or L8) is a piston engine with eight cylinders arranged in a straight line along the crankshaft. The number of cylinders and perfect primary and secondary engine balance resulted in smooth running, however there are several downsides relating to the significant length of the engine. Straight-eight engines were popular in luxury cars and racing cars in the 1920s to 1940s. During the 1950s, straight-eight engines were largely replaced by the more compact V8 engine design. Design A straight-eight can achieve perfect primary balance and secondary balance if an appropriate firing order is used. Like most other engines, torsional vibration of the crankshaft requires that a harmonic damper is installed on the crankshaft. at the accessory end of the crankshaft. As per other engines with 8 cylinders, the power delivery is smoother than engines with fewer cylinders. In the early 20th century, t ...

Duesenberg Model A
The Duesenberg Model A was the first automobile in series production to have hydraulic brakes and the first automobile in series production in the United States with a straight-eight engine. Officially known as the Duesenberg Straight Eight, the Model A was first shown in late 1920 in New York City. Production was delayed by substantial changes to the design of the car, including a change in the engine valvetrain from horizontal overhead valves to an overhead camshaft; also during this time, the company had moved its headquarters and factory from New Jersey to Indiana. The Model A was manufactured in Indianapolis, Indiana, from 1921 to 1925 by the Duesenberg Automobiles and Motors Company and from 1925 to 1926 at the same factory by the restructured Duesenberg Motor Company. The successors to the company began referring to the car as the Model A when the Model J was introduced. With a top speed of 71mph.

Duesenberg
Duesenberg Automobile and Motors Company, Inc. was an American racing and luxury automobile manufacturer founded in Indianapolis, Indiana, by brothers Fred and August Duesenberg in 1920. The company is known for popularizing the straight-eight engine and four-wheel hydraulic brakes. A Duesenberg car was the first American car to win a Grand Prix race, winning the 1921 French Grand Prix. Duesenbergs won the Indianapolis 500 in 1924, 1925, and 1927. Transportation executive Errett Lobban Cord acquired the Duesenberg corporation in 1926. The company was sold and dissolved in 1937. History Fred and August Duesenberg began designing engines in the early 1900s after Fred became involved with bicycle racing. The brothers designed a vehicle in 1905 and in 1906, formed the Mason Motor Car Company with funds from lawyer Edward R. Mason in Des Moines, Iowa. F.L. and Elmer Maytag acquired a majority stake in the company and renamed it the Maytag-Mason Automobile Company unt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overhead Camshaft Engine
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 O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V8 Engine
A V8 engine is an eight- cylinder piston engine in which two banks of four cylinders share a common crankshaft and are arranged in a V configuration. The first V8 engine was produced by the French Antoinette company in 1904, developed and used in cars and speedboats but primarily aircraft; while the American 1914–1935 ''Cadillac L-Head'' engine is considered the first road going V8 engine to be mass produced in significant quantities. The popularity of V8 engines in cars was greatly increased following the 1932 introduction of the ''Ford Flathead V8''. In the early 21st century, use of V8 engines in passenger vehicles declined as automobile manufacturers opted for more fuel efficient, lower capacity engines, or hybrid and electric drivetrains. Design V-angle The majority of V8 engines use a V-angle (the angle between the two banks of cylinders) of 90 degrees. This angle results in good engine balance, which results in low vibrations; however, the downside is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rolls-Royce Phantom IV
The Rolls-Royce Phantom IV is a British automobile produced by Rolls-Royce. Only eighteen were made between 1950 and 1956. They were only built for buyers whom Rolls-Royce considered worthy of the distinction: the British royal family and heads of state. Sixteen are currently known to still exist in museums as well as in public and private collections. Characteristics Rolls-Royce broke with their earlier decision to cease production of the series of "big" Rolls-Royce Phantoms after the end of World War II. The Phantom IV chassis differed from those of the shorter, production post-War models, the Silver Wraith and the Bentley Mark VI; apart from a larger size and an engine with increased capacity and power, they have an additional cross-member at the centre of the cruciform bracing and 10-stud road wheel mountings. The engine was a derivative of the 8-cylinder rationalized B range of petrol engines (formed by four, six and straight eight). Specifically it was a refined version ...

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- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
REO Motor Car Company
The REO Motor Car Company was a company based in Lansing, Michigan, which produced automobiles and trucks from 1905 to 1975. At one point, the company also manufactured buses on its truck platforms. Ransom E. Olds was an entrepreneur who founded multiple companies in the automobile industry. In 1897 Olds founded Oldsmobile. In 1905 Olds left Oldsmobile and established a new company, REO Motor Car Company, in Lansing, Michigan. Olds had 52% of the stock and the titles of president and general manager. To ensure a reliable supply of parts, he organized a number of subsidiary firms, like the National Coil Company, the Michigan Screw Company, and the Atlas Drop Forge Company. Originally the company was to be called "R. E. Olds Motor Car Company", but the owner of Olds' previous company, then called Olds Motor Works, objected and threatened legal action on the grounds of likely confusion of names by consumers. Olds then changed the name to his initials. Olds Motor Works soon adopted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Duesenberg Model J
The Duesenberg Model J is a luxury automobile made by Duesenberg. Intended to compete with the most luxurious and powerful cars in the world, it was introduced in 1928, the year before the stock market crash that led to the Great Depression. The Model J, available with a supercharger after 1932, was sold until Duesenberg Motors Company went bankrupt in 1937. Background E. L. Cord, the owner of Auburn Automobile, and other transportation firms, bought the Duesenberg Motor Corporation on October 26, 1926 for the brothers' engineering skills, talent and brand name. He intended to produce a car to rival the size, power, and luxury of top European brands such as Hispano-Suiza and Rolls-Royce. After Cord's takeover, the new company was renamed "Duesenberg, Inc." Fred would continue in the new organization with the title of vice president in charge of engineering and experimental work. Fred's brother August, who had played an important role in the development of the Model A and its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harmonic Damper
A harmonic damper is a device fitted to the free (accessory drive) end of the crankshaft of an internal combustion engine to counter torsional and resonance vibrations from the crankshaft. This device must be interference fit to the crankshaft in order to operate in an effective manner. An interference fit ensures the device moves in perfect step with the crankshaft. It is essential on engines with long crankshafts (such as straight-six or straight-eight engines) and V8 engines with cross plane cranks, or V6 and straight-three engines with uneven firing order. Harmonics and torsional vibrations can greatly reduce crankshaft life, or cause instantaneous failure if the crankshaft runs at or through an amplified resonance. Dampers are designed with a specific weight (mass) and diameter, which are dependent on the damping material/method used, to reduce mechanical Q factor, or damp, crankshaft resonances. A harmonic balancer (sometimes called crankshaft damper, torsional damper, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beardmore Tornado
The Beardmore Tornado was an eight-cylinder inline diesel aircraft engine Diesel may refer to: * Diesel engine, an internal combustion engine where ignition is caused by compression * Diesel fuel, a liquid fuel used in diesel engines * Diesel locomotive, a railway locomotive in which the prime mover is a diesel engine ... built in 1927 by William Beardmore and Company of Glasgow, Scotland, and used in the British R101 airship when petrol engines were thought unsafe in the tropics. The model is given as Tornado IIIA or Tornado III C.I. The fuel is described as ''Diesel heavy-oil''. Design and development The engine was designed by combining two four-cylinder units used for railcars into the eight-cylinder (MkI) engine. These were intended to give an output of at 1,000 rpm but in practice, had a continuous output rating of only with a maximum of . At 17 tons for the five, they were six tons above design weight.

Bugatti Type 35
The Bugatti Type 35 was the most successful of the Bugatti racing models. Its version of the Bugatti arch-shaped radiator that had evolved from the more architectural one of the Bugatti Type 13 Brescia, was to become the one that the marque is most known for though even in the ranks of the various Type 35s there were variations on the theme. The Type 35 was phenomenally successful, winning over 1,000 races in its time. It took the Grand Prix World Championship in 1926 after winning 351 races and setting 47 records in the two prior years. At its height, Type 35s averaged 14 race wins per week. Bugatti won the Targa Florio for five consecutive years, from 1925 through 1929, with the Type 35. Type 35 The original model, introduced at the Grand Prix of Lyon on August 3, 1924, used an evolution of the three-valve 2.0 L (1991 cc/121 in³) overhead cam straight-eight engine first seen on the Type 29.
