Cosworth RA
The RA is a 6.5-litre, naturally-aspirated V12 engine, commissioned by Adrian Newey, and designed, developed and produced by Cosworth for the Aston Martin Valkyrie sports car. The road-going engine is rated at at 10,500 rpm, with a max torque figure of at 7,000 rpm, making it the most powerful naturally-aspirated engine ever fitted and used in a production road car. The engine also revs to a maximum of 11,100 rpm, and has a power density making per litre. Background and development Aston Martin and Red Bull Advanced Technologies teamed up to blueprint an all-new hypercar, and needed to rely on a technological partner able to challenge the norm, and redefine parameters while performing against an incredible brief. According to Cosworth, it is intended to be "evoking the spine-tingling, ultra-high-revving F1 engines of the 1990s, but benefitting from two decades of progress in design, material and manufacturing expertise." Red Bull’s Chief Technical Officer, Ad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Formula One Engine
Since its inception in 1947, Formula One has used a variety of engine regulations. "Formulae" limiting engine capacity had been used in Grand Prix racing on a regular basis since after World War I. The engine formulae are divided according to era. Operation Formula One currently uses 1.6 litre four-stroke turbocharged 90 degree V6 double-overhead camshaft (DOHC) reciprocating engines. They were introduced in 2014 and have been developed over the subsequent seasons. The power a Formula One engine produces is generated by operating at a very high rotational speed, up to 20,000 revolutions per minute (rpm). However, they are electronically limited to 15,000 as of 2021 season. This contrasts with road car engines of a similar size, which typically operate at less than 6,000 rpm. The basic configuration of a naturally aspirated Formula One engine had not been greatly modified since the 1967 Ford Cosworth DFV and the mean effective pressure had stayed at around 14 b ...

Electric Battery
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. The terminal marked negative is the source of electrons that will flow through an external electric circuit to the positive terminal. When a battery is connected to an external electric load, a redox reaction converts high-energy reactants to lower-energy products, and the free-energy difference is delivered to the external circuit as electrical energy. Historically the term "battery" specifically referred to a device composed of multiple cells; however, the usage has evolved to include devices composed of a single cell. Primary (single-use or "disposable") batteries are used once and discarded, as the electrode materials are irreversibly changed during discharge; a common example is the alkaline battery used f ...

Electric Motor
An electric motor is an Electric machine, electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a Electromagnetic coil, wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy. Electric motors can be powered by direct current (DC) sources, such as from batteries, or rectifiers, or by alternating current (AC) sources, such as a power grid, Inverter (electrical), inverters or electrical generators. Electric motors may be classified by considerations such as power source type, construction, application and type of motion output. They can be powered by AC or DC, be Brushed motor, brushed or Brushless motor, brushless, single-phase, Two-phase electric power, two-p ...

Hybrid Vehicle Drivetrain
Hybrid vehicle drivetrains transmit power to the driving wheels for hybrid vehicles. A hybrid vehicle has multiple forms of motive power. Hybrids come in many configurations. For example, a hybrid may receive its energy by burning gasoline, but switch between an electric motor and a combustion engine. Electrical vehicles have a long history combining internal combustion and electrical transmission as in a diesel–electric power-train although they have mostly been used for rail locomotives. A diesel–electric powertrain fails the definition of hybrid because the electric drive transmission directly replaces the mechanical transmission rather than being a supplementary source of motive power. One of the earliest forms of hybrid land vehicle was the 'trackless' trolleybus experiment in The United States (New Jersey) that ran from 1935 to 1948, which normally used traction current delivered by wire. The trolleybus was fitted with an internal combustion engine (ICE) to power the m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aston Martin One-77
The Aston Martin One-77 is a two-door, two-seater flagship sports car built by the British car manufacturer Aston Martin. The car was first shown at the 2008 Paris Motor Show, although it remained mostly covered by a "Savile Row tailored skirt" throughout the show. It was revealed in full at the 2009 Geneva Motor Show, and deliveries began in 2011. The production of the One-77 was limited to 77 cars, although several development cars were made for engineering, testing, and marketing. One of the development cars, VIN #10711 was sent back to Aston Martin for complete refurbishment, and now is owned under NHTSA Show and Display registration in the United States, making the actual total of cars in existence to be 78. The car's development formed part of the name One-77, and sold for 1,150,000. In May 2012, one of the 77 cars was involved in a crash in Hong Kong and was initially written off, but has since been fully rebuilt. Specifications Prior to the One-77's Paris Motor Sh ...

Oil Pan
A sump is a low space that collects often undesirable liquids such as water or chemicals. A sump can also be an infiltration basin used to manage surface runoff water and recharge underground aquifers. Sump can also refer to an area in a cave where an underground flow of water exits the cave into the earth. Examples One common example of a sump is the lowest point in a basement, into which flows water that seeps in from outside. If this is a regular problem, a sump pump that moves the water outside of the house may be used. Another example is the oil pan of an engine. The oil is used to lubricate the engine's moving parts and it pools in a reservoir known as its sump, at the bottom of the engine. Use of a sump requires the engine to be mounted slightly higher to make space for it. Often though, oil in the sump can slosh during hard cornering, starving the oil pump. For these reasons, racing motorcycles and piston aircraft engines are "dry sumped" using scavenge pumps and a s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engine Block
In an internal combustion engine, the engine block is the structure which contains the cylinders and other components. In an early automotive engine, the engine block consisted of just the cylinder block, to which a separate crankcase was attached. Modern engine blocks typically have the crankcase integrated with the cylinder block as a single component. Engine blocks often also include elements such as coolant passages and oil galleries. The term "cylinder block" is often used interchangeably with "engine block", although technically, the block of a modern engine (i.e. multiple cylinders integrated with another component) would be classified as a monobloc. __TOC__ Construction The main structure of an engine typically consists of the cylinders, coolant passages, oil galleries, crankcase, and cylinder head(s). The first production engines of the 1880s to 1920s usually used separate components for each of these elements, which were bolted together during engine assembly. ...

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] |
Camshaft
A camshaft is a shaft that contains a row of pointed cams, in order to convert rotational motion to reciprocating motion. Camshafts are used in piston engines (to operate the intake and exhaust valves), mechanically controlled ignition systems and early electric motor speed controllers. Camshafts in piston engines are usually made from steel or cast iron, and the shape of the cams greatly affects the engine's characteristics. History Trip hammers are one of the early uses of a form of cam to convert rotating motion, e.g. from a waterwheel, into the reciprocating motion of a hammer used in forging or to pound grain. Evidence for these exists back to the Han Dynasty in China, and they were widespread by the medieval period. The camshaft was described in 1206 by engineer Al-Jazari. He employed it as part of his automata, water-raising machines, and water clocks such as the castle clock. Once the rotative version of the steam engine was developed in the late 18th century, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
