Jensen Healey
The Jensen-Healey is a British two-seater convertible sports car, produced by Jensen Motors Ltd. in West Bromwich, England from 1972 until 1976. Launched in 1972 as a luxurious and convertible sports car, it was positioned in the market between the Triumph TR6 and the Jaguar E-Type. A related fastback, the Jensen GT, was introduced in 1975. Design When production of the Austin-Healey 3000 ended, Donald Healey opened discussions with Jensen Motors, who had built the bodies for Healey's Austin-Healey cars. The largest Austin-Healey dealer in the U.S., San Francisco-based Kjell Qvale, was also keen to find a replacement to the Austin-Healey 3000; Qvale would become a major shareholder of Jensen, making Donald Healey the chairman. The Jensen-Healey was developed in a joint venture by Donald Healey, his son Geoffrey, and Jensen Motors. Hugo Poole did the styling of the body, the front, and back of which were later modified by William Towns to take advantage of the low profile engin ...

Lotus 907
The Lotus 907 is an inline-4 automobile engine designed and manufactured by Lotus Cars. Displacing , it is all-alloy, and features dual overhead camshafts (DOHC) and 16 valves. It developed approximately with dual side-draft Dell'Orto carburetors in most markets and Zenith Stromberg carburetors for US cars. It was nicknamed "The Torqueless Wonder" for its lack of bottom end but good high end horsepower. History The Lotus 907 was the first production variant of the Lotus 900 series engine. The Jensen-Healey was the first production car to receive the 907. It is said that when Vauxhall unveiled its new slant-four engine at the 1967 Earls Court Motor Show its bore centers were exactly the same as those proposed by Lotus. Colin Chapman immediately negotiated a deal with Vauxhall to buy some of their cast-iron blocks so that development of Lotus' own aluminum cylinder head could be sped up to produce the 907 engine. Applications The Type 75 Lotus Elite, Type 76 Lotus Eclat, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jensen Motors
Jensen Motors Limited was a British manufacturer of sports cars and commercial vehicles in West Bromwich, England. Brothers Alan and Richard Jensen gave the new name, Jensen Motors Limited, to the commercial body and sports car body making business of W J Smith & Sons Limited in 1934. It ceased trading in 1976. Though trading resumed in 1998, Jensen Motors Limited was dissolved in 2011. Jensen Motors built specialist car bodies for major manufacturers alongside cars of their own design using engines and mechanicals of major manufacturers Ford, Austin and Chrysler. The rights to Jensen's trademarks were bought with the company and it briefly operated in Speke, Liverpool, from 1998 to 2002. Under subsequent owners, a new version of the Jensen Interceptor was announced in 2011. It was planned to bring manufacture of that new model back to the former Jaguar motor plant in Browns Lane, Coventry. Jensen brothers In 1926 young Alan Jensen (1906-1994) and his brother Richard Jense ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Multi-valve
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 red ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poppet Valve
A poppet valve (also called mushroom valve) is a valve typically used to control the timing and quantity of gas or vapor flow into an engine. It consists of a hole or open-ended chamber, usually round or oval in cross-section, and a plug, usually a disk shape on the end of a shaft known as a valve stem. The working end of this plug, the valve face, is typically ground at a 45° bevel to seal against a corresponding valve seat ground into the rim of the chamber being sealed. The shaft travels through a valve guide to maintain its alignment. A pressure differential on either side of the valve can assist or impair its performance. In exhaust applications higher pressure against the valve helps to seal it, and in intake applications lower pressure helps open it. The poppet valve was invented in 1833 by American E.A.G. Young of the New Castle and Frenchtown Turnpike and Railroad Company, Newcastle and Frenchtown Railroad. Young had patented his idea, but the 1836 U.S. Patent Offic ...

Overhead Camshaft
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] |

Industrial Action
Industrial action (British English) or job action (American English) is a temporary show of dissatisfaction by employees—especially a strike action, strike or slowdown or working to rule—to protest against bad working conditions or low pay and to increase bargaining power with the employer and intended to force the employer to improve them by reducing productivity in a workplace. Industrial action is usually organized by trade unions or other organised labour, most commonly when employees are forced out of work due to contract termination and without reaching an agreement with the employer. Quite often it is used and interpreted as a euphemism for strike action, strike or mass strike, but the scope is much wider. Industrial action may take place in the context of a labour dispute or may be meant to effect political or social change. This form of communication tends to be their only means to voice their concerns about safety and benefits. Types *Strike action, Strike *Occup ...

V6 Engine
A V6 engine is a six-cylinder piston engine where the cylinders share a common crankshaft and are arranged in a V configuration. The first V6 engines were designed and produced independently by Marmon Motor Car Company, Deutz Gasmotoren Fabrik and Delahaye. Engines built after World War II include the Lancia V6 engine in 1950 for the Lancia Aurelia, and the Buick V6 engine in 1962 for the Buick Special. The V6 layout has become the most common layout for six-cylinder automotive engines. Design Due to their short length, V6 engines are often used as the larger engine option for vehicles which are otherwise produced with inline-four engines, especially in transverse engine vehicles. A downside for luxury cars is that V6 engines produce more vibrations than straight-six engines. Some sports cars use flat-six engines instead of V6 engines, due to their lower centre of gravity (which improves the handling). The displacement of modern V6 engines is typically between , though ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
