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, these sm ...

Rolls-Royce B Engine
The Rolls-Royce B range was a range of petrol engines first intended to be installed in a car but in 1943 developed into a range to power the British Army's wheeled vehicles.Rolls-Royce Motors Holdings Limited. ''The Times'', Monday, May 07, 1973; pg. 23; Issue 58775 The Alvis Saladin and Rolls-Royce Phantom IV were fitted with 8-cylinder versions. Overview Common features The B range of engines were all of the inline configuration, with crossflow inlet-over-exhaust cylinder heads and were naturally aspirated. They were heavily rationalized engines, which made use of as many common parts across the range as possible, for example, the 8 cylinder versions used 2 sets of the oil bath air filters, exhaust manifolds and points components of the 4 cylinder, while using the same carburettor as the 6. Pistons, rods, valves, springs, liners, etc. were common across the range, until the introduction of the overbored xx1 series, which still attempted to use as many common componen ...

Delage Engine
Delage was a French luxury automobile and racecar company founded in 1905 by Louis Delâge in Levallois-Perret near Paris; it was acquired by Delahaye in 1935 and ceased operation in 1953. On 7 November 2019, the association "Les Amis de Delage", created in 1956 and owner of the Delage brand, announced the re-founding of the company Delage Automobiles. Early history The company was founded in 1905 by Louis Delâge, who borrowed Fr 35,000, giving up a salary of F 600 a month to do so. Hull, p. 517. Its first location was on the Rue Cormeilles in Levallois-Perret. The company at first had just two lathes and three employees, one of them Peugeot's former chief designer. Delage initially produced parts for Helbé, with the De Dion-Bouton engine and chassis assembled by Helbé; Delage added only the body. The first model was the Type A, a ''voiturette'' which appeared in 1906. It was powered by a one-cylinder De Dion-Bouton of . Like other early carmakers, Delage participated ...

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 larg ... [...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 v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engine Balance
Engine balance refers to how the forces (resulting from combustion or rotating/reciprocating components) are balanced within an internal combustion engine or steam engine. The most commonly used terms are ''primary balance'' and ''secondary balance''. ''First-order balance'' and ''second-order balance'' are also used. Unbalanced forces within the engine can lead to vibrations. Causes of imbalance Although some components within the engine (such as the connecting rods) have complex motions, all motions can be separated into reciprocating and rotating components, which assists in the analysis of imbalances. Using the example of an inline engine (where the pistons are vertical), the main reciprocating motions are: * Pistons moving upwards/downwards * Connecting rods moving upwards/downwards * Connecting rods moving left/right as they rotate around the crankshaft, however the lateral vibrations caused by these movements are much smaller than the up–down vibrations caused by ...

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 versio ...

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. Bore was 60 mm and stroke was 88 mm as on many previous ... [...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 OHV en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Leyland Eight
The Leyland Eight was a luxury car produced by Leyland Motors from 1920 to 1923. The car was designed by the chief engineer of Leyland Motors, J.G. Parry-Thomas and his assistant Reid Railton, and was intended to be the finest car available. It was the first British car with a straight-eight engine. The Eight was introduced to the public at the 1920 International Motor Exhibition at Olympia, London, where it was referred to as the "Lion of Olympia". Engine and transmission The engine, with cylinder block and upper crankcase cast in one piece, had a single centrally mounted overhead camshaft, hemispherical combustion chambers, and an bore. The engine was offered in one of two capacities: with a stroke, producing at 2,500 rpm or with a stroke and twin carburettors, producing at 3,500 rpm. The crankshaft ran in five bearings. Ignition was by coil and distributor rather than magneto which was the more usual British practice at the time. Transmission was through a ...
