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, A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Inline-three Engine
A straight-three engine (also called an inline-triple or inline-three) is a three-cylinder reciprocating engine, piston engine where cylinders are arranged in a line along a common crankshaft. Less common than straight-four engine, straight-three engines have nonetheless been used in various motorcycles, cars and agricultural machinery. Design A crankshaft angle of 120 degrees is typically used by straight-three engines, since this results in an evenly spaced Firing order#Firing interval, firing interval. Another benefit of this configuration is perfect Engine balance#Primary balance, primary balance and Engine balance#Secondary balance, secondary balance, however an end-to-end Couple (mechanics), rocking couple is induced because there is no symmetry in the piston velocities about the middle piston. A balance shaft is sometimes used to reduce the vibrations caused by the rocking couple. Other crankshaft angles have been used occasionally. The 1976–1981 Laverda Jota motorcyc ...

Hybrid Vehicle Drivetrain
Hybrid vehicle drivetrains transmit power to the driving wheels for hybrid vehicles. A hybrid vehicle has multiple forms of motive power, and can 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. A typical powertrain includes all of the components used to transform stored potential energy. Powertrains may either use chemical, solar, nuclear or kinetic energy for propulsion. The oldest example is the steam locomotive. Modern examples include electric bicycles and hybrid electric vehicles, which generally combine a battery (or supercapacitor) supplemented by an internal combustion engine (ICE) that can either recharge the batteries or power the vehicle. Other hybrid powertrains can use flywheels to store energy. Among different types of hybrid vehicles, only the electric/ICE type is commercially available as of 2017. One variety operated in parallel to provide power from both ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kinetic Energy Recovery System
A kinetic energy recovery system (KERS) is an automotive system for recovering a moving vehicle's kinetic energy under braking. The recovered energy is stored in a reservoir (for example a flywheel or high voltage batteries) for later use under acceleration. Examples include complex high end systems such as the Zytek, Flybrid, Torotrak and Xtrac used in Formula One racing and simple, easily manufactured and integrated differential based systems such as the Cambridge Passenger/Commercial Vehicle Kinetic Energy Recovery System (CPC-KERS). Xtrac and Flybrid are both licensees of Torotrak's technologies, which employ a small and sophisticated ancillary gearbox incorporating a continuously variable transmission (CVT). The CPC-KERS is similar as it also forms part of the driveline assembly. However, the whole mechanism including the flywheel sits entirely in the vehicle's hub (looking like a drum brake). In the CPC-KERS, a differential replaces the CVT and transfers torque between ... [...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 National Highway Traffic Safety Administration (NHTSA) Show or 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. Spe ...

Oil Pan
An oil is any nonpolar chemical substance that is composed primarily of hydrocarbons and is hydrophobic (does not mix with water) and lipophilic (mixes with other oils). Oils are usually flammable and surface active. Most oils are unsaturated lipids that are liquid at room temperature. The general definition of oil includes classes of chemical compounds that may be otherwise unrelated in structure, properties, and uses. Oils may be animal, vegetable, or petrochemical in origin, and may be volatile or non-volatile. They are used for food (e.g., olive oil), fuel (e.g., heating oil), medical purposes (e.g., mineral oil), lubrication (e.g. motor oil), and the manufacture of many types of paints, plastics, and other materials. Specially prepared oils are used in some religious ceremonies and rituals as purifying agents. Etymology First attested in English 1176, the word ''oil'' comes from Old French ''oile'', from -4; we might wonder whether there's a point at which it' ...

Engine Block
In an internal combustion engine, the engine block is the structure that contains the cylinders and other components. The engine block in an early automotive engine 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". However, 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 element, which were bolted together during engine assembly. Modern en ...

Crankshaft
A crankshaft is a mechanical component used in a reciprocating engine, piston engine to convert the reciprocating motion into rotational motion. The crankshaft is a rotating Shaft (mechanical engineering), 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 (metalworking), casting or machining process. Design The crankshaft is located within the engine block and 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 enormou ...

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. Camshafts were first described by Ismail al-Jazari in 1206. Once the rotative version of the steam engine was developed in the late 18th century, the operation of the valve gear was usually by an eccentric, which turned the rotation of the crankshaft i ...

Cosworth TJ / CA Engine
The TJ and CA series are a family of naturally-aspirated V10 and V8 Formula One racing engines, in both 2.4-litre and 3-litre engine configurations, designed and developed by Cosworth; and produced between and . The customer engines were used by Minardi, Red Bull, Toro Rosso, Williams, Lotus, HRT, Virgin, and Marussia. Background Jaguar pulled out of F1 at the end of 2004, but the team (renamed Red Bull Racing) continued to use Cosworth V10 engines until switching to a Ferrari V8 for 2006. Minardi also used re-badged Cosworth engines until 2005. Williams began testing the new CA2006 2.4-litre V8 in November 2005, which produced about 755 bhp @ 19,250 rpm (315 hp/L), and began using Cosworth V8 engines for the 2006 season. In the same year, Scuderia Toro Rosso used detuned V10 engines based on the 2005 units. For 2006, engines had to be a 90° V8 configuration of 2.4 litres maximum capacity with a circular bore of maximum, which implies a stroke at maxi ...

V10 Engine
A V10 engine is a ten- cylinder piston engine where two banks of five cylinders are arranged in a V configuration around a common crankshaft. V10 engines are much less common than V8 and V12 engines. Several V10 diesel engines have been produced since 1965, and V10 petrol engines for road cars were first produced in 1991 with the release of the Dodge Viper. Design The V10 configuration does not have perfect engine balance, since an unbalanced rocking couple is caused by each cylinder bank functioning as a straight-five engine. Therefore, balance shafts are sometimes used to reduce the vibrations in a V10 engine. Diesel engines One of the first known V10 engines was used in the 1936 ''Busch-Sulzer ICRR 9201'' prototype locomotive, of which three examples were produced in the United States. The 1965–1984 Leopard 1 armored tank was powered by the ''MTU MB 838 CaM 500'' V10 diesel engine. Daimler-Benz produced three V10 diesel engine models (OM403, OM423 and OM443) ...
