Lotus 900 Series
The Lotus 900 series is a family of internal combustion engines designed and built by Lotus Cars of United Kingdom. Successor to the Lotus-Ford Twin Cam, the 900 was the first complete engine developed by Lotus. The engine was built from 1972 to 1999. Background As early as 1964, Lotus recognized the need to find a replacement for the Lotus Twin Cam engine. Colin Chapman issued a brief that listed the features to be required in a new engine, including 'high efficiency, flexibility, torque and smoothness which was suitable for hand assembly'. Unable to find this combination in any existing engine, the company used outside consultants and internal resources to define the characteristics of the next Lotus engine. After having rejected a 120° V6 due to being too wide for Lotus' chassis and a 60° V6 as too tall for the intended bodywork, the engineers determined that a 2-litre inline-four engine was the optimal choice. This future engine would have four valves per cylinder (16 val ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jetronic
Jetronic is a trade name of a manifold injection technology for automotive petrol engines, developed and marketed by Robert Bosch GmbH from the 1960s onwards. Bosch licensed the concept to many automobile manufacturers. There are several variations of the technology offering technological development and refinement. D-Jetronic (1967–1979) Analogue fuel injection, 'D' is from german: "Druck" meaning pressure. Inlet manifold vacuum is measured using a pressure sensor located in, or connected to the intake manifold, in order to calculate the duration of fuel injection pulses. Originally, this system was called Jetronic, but the name D-Jetronic was later created as a retronym A retronym is a newer name for an existing thing that helps differentiate the original form/version from a more recent one. It is thus a word or phrase created to avoid confusion between older and newer types, whereas previously (before there were ... to distinguish it from subsequent Jetronic iterations. D-J ...

Vauxhall Victor
The Vauxhall Victor is a large family car produced by Vauxhall from 1957 until 1976. The Victor was introduced to replace the outgoing Wyvern model. It was renamed Vauxhall VX Series in 1976 and continued in production until 1978, by which time it had grown significantly and was viewed, at least in its home market, as a larger-than-average family car. The last Victor, the Victor FE, was also manufactured under licence by Hindustan Motors in India as the Hindustan Contessa, during the 1980s and early 2000s, with an Isuzu engine. The FD Series was replaced by the Vauxhall Cavalier, while the larger FE Series was replaced by the Vauxhall Carlton. The Victor briefly became Britain's most exported car, with sales in markets as far flung as the United States (sold by Pontiac dealers, since Vauxhall had been part of GM from 1925), Canada, Australia, New Zealand, South Africa, and Asian right-hand drive markets such as Ceylon (now Sri Lanka), India, Pakistan, Malaysia, Thailand, and S ...

British International Motor Show
The British International Motor Show is an annual motor show held by the Society of Motor Manufacturers and Traders between 1903 and 2008 in England, and as The British Motor Show since 2021 by Automotion Events. Initially held in London at The Crystal Palace, Olympia and then the Earls Court Exhibition Centre, it moved to the National Exhibition Centre in Birmingham in 1978, where it stayed until 2004. It was held at ExCeL London in 2006 and 2008 and now based in Farnborough (Hampshire) at the airport exhibition centre. The 2010 and 2012 events were cancelled due to the global financial crisis. Between 2016 and 2019 there were annual motor shows held under the London Motor Show banner. The show returned in 2021 to Farnborough under the banner of The British Motor Show and was the first international motor show event to take place after the lifting of coronavirus measures. The event recorded 45,000 visitors in its first year returning, and proceeded to grow to almost 60,00 ... [...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] |
Coventry Climax
Coventry Climax was a British forklift truck, fire pump, racing, and other specialty engine manufacturer. History Pre WW1 The company was started in 1903 as Lee Stroyer, but two years later, following the departure of Stroyer, it was relocated to Paynes Lane, Coventry, and renamed as Coventry-Simplex by H. Pelham Lee, a former Daimler Company, Daimler employee, who saw a need for competition in the nascent piston engine market. An early user was GWK (car), GWK, who produced over 1,000 light cars with Coventry-Simplex two-cylinder engines between 1911 and 1915. Just before the First world war, First World War, a Coventry-Simplex engine was used by Lionel Martin to power the first Aston Martin car. Ernest Shackleton selected Coventry-Simplex to power the tractors that were to be used in his Imperial Trans-Antarctic Expedition of 1914. Hundreds of Coventry-Simplex engines were manufactured during the First World War to be used in generating sets for searchlights. Post WW1 In 1 ...

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] |
Timing Belt (camshaft)
In a piston engine, either a timing belt (also called a ''cambelt'') or timing chain or set of timing gears is used to synchronize the rotation of the crankshaft and the camshaft. This synchronisation ensures that the engine's valves open and close at the correct times in relation to the position of the pistons. Design In most piston engines, the camshaft(s) are mechanically connected to the crankshaft. The crankshaft drives the camshaft (via a timing belt, timing chain or pushrods), which in turn actuates the intake and exhaust valves. These valves allow the engine to inhale air (or an air/fuel mixture) and exhale the exhaust gasses. The most common devices to transfer the drive are toothed rubber belts, metal timing chains or a set of gears. The teeth of the belt/chain/gears mesh with both the crankshaft and camshaft(s), thereby synchronising their motion. In many older overhead valve engines, the camshaft is located in the block near the crankshaft, therefore a simple gear ... [...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 ...

Colin Chapman
Anthony Colin Bruce Chapman (19 May 1928 – 16 December 1982) was an English design engineer, inventor, and builder in the automotive industry, and founder of Lotus Cars. In 1952 he founded the sports car company Lotus Cars. Chapman initially ran Lotus in his spare time, assisted by a group of enthusiasts. His knowledge of the latest aeronautical engineering techniques would prove vital towards achieving the major automotive technical advances for which he is remembered. His design philosophy focused on cars with light weight and fine handling instead of bulking up on horsepower and spring rates, which he famously summarised as "Adding power makes you faster on the straights. Subtracting weight makes you faster everywhere." Under his direction, Team Lotus won seven Formula One Constructors' titles, six Drivers' Championships, and the Indianapolis 500 in the United States, between 1962 and 1978. The production side of Lotus Cars has built tens of thousands of relati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internal Combustion Engine
An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons ( piston engine), turbine blades (gas turbine), a rotor (Wankel engine), or a nozzle ( jet engine). This force moves the component over a distance, transforming chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to. This replaced the external combustion engine for applications where the weight or size of an engine was more important. The first commercially successful internal combustion engine was created by Étienne Lenoir around 1860, and the first modern internal combustion engine, known ...
