Formula One Engines
This article gives an outline of Formula One engines, also called Formula One power units since the hybrid era starting in 2014. Since its inception in 1947, Formula One has used a variety of engine Formula One regulations, 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 #Engine regulation progression by era, era. Characteristics Formula One currently uses 1.6 litre four-stroke turbocharged 90 degree V6 engine, V6 overhead camshaft engine#Double overhead camshaft, double-overhead camshaft (DOHC) reciprocating engines. They were introduced in 2014 and have been developed over the subsequent seasons. Mostly from the 2023 season, specifications on Formula One engines, including the software used to control them and the maximum per-engine price to F1 teams of €15,000,000, have been frozen until the end of 2025, when the completely new 2026 spec will c ...

Engine Displacement
Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. It is commonly used as an expression of an engine's size, and by extension as an indicator of the power (through mean effective pressure and rotational speed) an engine might be capable of producing and the amount of fuel it should be expected to consume. For this reason displacement is one of the measures often used in advertising, as well as regulating, motor vehicles. It is usually expressed using the metric units of cubic centimetres (cc or cm3, equivalent to millilitres) or litres (l or L), orparticularly in the United States cubic inches (CID, cu in, or in3). Definition The overall displacement for a typical reciprocating piston engine is calculated by multiplying together three values; the distance travelled by the piston (the stroke length), the circular area of the cylinder, and the number of cylinders in the whole e ...

Connecting Rod
A connecting rod, also called a 'con rod', is the part of a reciprocating engine, piston engine which connects the piston to the crankshaft. Together with the crank (mechanism), crank, the connecting rod converts the reciprocating motion of the piston into the rotation of the crankshaft. The connecting rod is required to transmit the compressive and tensile forces from the piston. In its most common form, in an internal combustion engine, it allows pivoting on the piston end and rotation on the shaft end. The predecessor to the connecting rod is a mechanic linkage used by water mills to convert rotating motion of the water wheel into reciprocating motion. The most common usage of connecting rods is in internal combustion engines or on steam engines. __TOC__ Origins A connecting rod crank has been found in the Celtic Oppida at Paule in Brittany, dated to 69 BC. The predecessor to the connecting length is the Linkage (mechanical), mechanical linkage used by List of Roman wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BRM P75
The BRM P75 was a 3-litre (183 cu. in.) H16 motor racing engine, developed by BRM. The engine was relatively competitive but highly unreliable, and was used in Formula One from to . Background Regulation changes In 1965, the Fédération Internationale de l'Automobile, that administered Formula One racing, agreed to raise the series' maximum engine capacity from to from 1966. Up until that point, BRM was challenging at the top with Lotus, Cooper and Ferrari. Development BRM decided to hedge their bets by developing their existing 16 valve 1.5 litre V8 into a 32 valve 3 litre H16 (effectively two flat 8s, one on top of the other and geared together) while also developing a new 48 valve 3 litre V12 in partnership with Harry Weslake and opt for whichever turned out to be the better powerplant. After much debate, Sir Alfred Owen decided BRM would go with the H16 and Weslake bought out BRM's involvement in the V12 and produced the engine that went on to power the Eagle T1G. The ...

BRM Type 15
The BRM Type 15 was a Formula One racing car of the early 1950s, and the first car produced by British Racing Motors. The car was fitted with a revolutionary and highly complex supercharged 1.5-litre British Racing Motors V16 which produced considerably more power than any of its contemporaries. The distinctive noise of the car made it a favourite with crowds wherever it appeared, but the initial unreliability of the car, its inability to live up to the hype that the project's leading figures had created around it, and the change to Formula Two regulations in 1952 meant the project never achieved the hoped-for level of success on the Grand Prix stage; the car's complexities meant it had a longer development time than its competitors and was not properly competitive until 1953 (3 years after it first raced), where it saw success at non-championship events. Background After the end of the Second World War motor racing slowly returned, based on whatever machinery could be found, l ...

Stroke Ratio
Stroke ratio, today universally defined as bore/stroke ratio, is a term to describe the ratio between cylinder bore diameter and piston stroke length in a reciprocating piston engine. This can be used for either an internal combustion engine, where the fuel is burned within the cylinders of the engine, or external combustion engine, such as a steam engine, where the combustion of the fuel takes place ''outside'' the working cylinders of the engine. Conventions The contemporary convention for describing the ''stroke ratio'' of a piston engine‘s cylinders is its ''bore/stroke'' ratio. ''Stroke/bore'' ratio is an obsolete expression dating to the early era of reciprocating engine development. Bore/stroke ratio The diameter of the cylinder bore is divided by the length of the piston stroke to give the ratio. Square, oversquare and undersquare engines The following terms describe the naming conventions for the configurations of the various bore/stroke ratio: Square A square ...

Secondary Vibration
Engine balance refers to how the inertial forces produced by moving parts in an internal combustion engine or steam engine are neutralised with counterweights and balance shafts, to prevent unpleasant and potentially damaging vibration. The strongest inertial forces occur at crankshaft speed (first-order forces) and balance is mandatory, while forces at twice crankshaft speed (second-order forces) can become significant in some cases. 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 movemen ...

Standard Gravity
The standard acceleration of gravity or standard acceleration of free fall, often called simply standard gravity and denoted by or , is the nominal gravitational acceleration of an object in a vacuum near the surface of the Earth. It is a constant defined by standard as . This value was established by the third General Conference on Weights and Measures (1901, CR 70) and used to define the standard weight of an object as the product of its mass and this nominal acceleration. The acceleration of a body near the surface of the Earth is due to the combined effects of gravity and centrifugal acceleration from the rotation of the Earth (but the latter is small enough to be negligible for most purposes); the total (the apparent gravity) is about 0.5% greater at the poles than at the Equator. Although the symbol is sometimes used for standard gravity, (without a suffix) can also mean the local acceleration due to local gravity and centrifugal acceleration, which varies depending on on ...

Metallurgy
Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are known as alloys. Metallurgy encompasses both the science and the technology of metals, including the production of metals and the engineering of metal components used in products for both consumers and manufacturers. Metallurgy is distinct from the craft of metalworking. Metalworking relies on metallurgy in a similar manner to how medicine relies on medical science for technical advancement. A specialist practitioner of metallurgy is known as a metallurgist. The science of metallurgy is further subdivided into two broad categories: chemical metallurgy and physical metallurgy. Chemical metallurgy is chiefly concerned with the reduction and oxidation of metals, and the chemical performance of metals. Subjects of study in chemical metallurgy include mineral processing, the extraction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spring Rate
A spring is a device consisting of an elastic but largely rigid material (typically metal) bent or molded into a form (especially a coil) that can return into shape after being compressed or extended. Springs can store energy when compressed. In everyday use, the term most often refers to coil springs, but there are many different spring designs. Modern springs are typically manufactured from spring steel. An example of a non-metallic spring is the bow, made traditionally of flexible yew wood, which when drawn stores energy to propel an arrow. When a conventional spring, without stiffness variability features, is compressed or stretched from its resting position, it exerts an opposing force approximately proportional to its change in length (this approximation breaks down for larger deflections). The ''rate'' or ''spring constant'' of a spring is the change in the force it exerts, divided by the change in deflection of the spring. That is, it is the gradient of the forc ...
