Hart 420 Engine
The Hart 420R and the Hart 420S are four-stroke, naturally aspirated, , four-cylinder engine, designed, developed and made by Hart Racing Engines, and tuned by Brian Hart, for Formula 2 and sports prototype racing applications, between 1975 and 1980. The 420R is based on the Cosworth FVA, while the 420S is based on the Cosworth BDG, with the design knowledge being taken and used on both. The Hart 420R F2 engine owes much to the Cosworth BDA series, being essentially an aluminium-block derivative using similar heads. Both the 420R and 420S were naturally-aspirated, 2-litre, 16-valve DOHC, fuel-injected, straight-four engines.

Hart Racing Engines
Brian Hart Ltd., also known as Hart and Hart Racing Engines, was a motor racing engine manufacturer that participated in 157 Formula One Grands Prix, powering a total of 368 entries. Founded in 1969 by British engineer Brian Hart, Hart initially concentrated on servicing and tuning engines from other manufacturers for various independent British teams at all levels of motorsport. Hart found particular success with developments of Ford's FVA engine, eventually leading the large multinational company to approach the small independent to develop the Ford BDA 1.6 L engine for the 2.0L class. The European Formula Two title was won in both 1971 and 1972 with Hart-built Ford engines, and the 2.0 L BDA engine powered the majority of Ford's 1970s rallying successes. With Ford's withdrawal from F2 in the mid-1970s, Hart began to concentrate on building their own designs. The first engine to bear the Hart name alone was the twin-cam, four-cylinder Hart 420R F2 unit, which appear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cosworth BDA
Cosworth is a British automotive engineering company founded in London in 1958, specialising in high-performance internal combustion engines, powertrain, and electronics for automobile racing (motorsport) and mainstream automotive industries. Cosworth is based in Northampton, England, with American facilities in Indianapolis and Mooresville, North Carolina.

Chevron B31
The Chevron B31 was a sports prototype racing car built by Chevron Cars Ltd in 1975, and initially used in the European 2-Litre Championship. The car was an evolution of the Chevron B26, and was initially fitted with a 2-litre Hart 420R straight-four engine producing . However, various other engines were used; the car also ran with engines such as the 3-litre Cosworth DFV V8, the 2-litre Cosworth FVD/Cosworth BDG straight-four engines, and the 2-litre BMW M12 straight-four, amongst others. Design The Chevron B31 was an evolution of the B26, and was designed for the European 2-Litre Championship by Chevron Cars Ltd's founder Derek Bennett in 1975; six cars were built. The B31 featured subtle changes, such as a slightly redesigned bodywork, but it featured the same basic aluminium monocoque chassis as its predecessor. The bodywork was made from fiberglass, and the B31 was designed to use the same Hart 420R engine as its predecessor had. The 420R was a naturally-aspirated 2-li ...

Formula Two
Formula Two (F2 or Formula 2) is a type of open-wheel formula racing category first codified in 1948. It was replaced in 1985 by Formula 3000, but revived by the FIA from 2009–2012 in the form of the FIA Formula Two Championship. The name returned in 2017 when the former GP2 Series became known as the FIA Formula 2 Championship. History While Formula One has generally been regarded as the pinnacle of open-wheeled auto racing, the high-performance nature of the cars and the expense involved in the series has always meant a need for a path to reach this peak. For much of the history of Formula One, Formula Two has represented the penultimate step on the motorsport ladder. Pre-war Prior to the Second World War, there usually existed a division of racing for cars smaller and less powerful than Grand Prix racers. This category was usually called voiturette ("small car") racing and provided a means for amateur or less experienced drivers and smaller marques to prove themselves. ...

Piston Stroke
In the context of an internal combustion engine, the term stroke has the following related meanings: * A phase of the engine's cycle (e.g. compression stroke, exhaust stroke), during which the piston travels from top to bottom or vice versa. * The type of power cycle used by a piston engine (e.g. two-stroke engine, four-stroke engine). * "Stroke length", the distance travelled by the piston during each cycle. The stroke length––along with bore diameter––determines the engine's displacement. Phases in the power cycle Commonly used engine phases or strokes (i.e. those used in a four-stroke engine) are described below. Other types of engines can have very different phases. Induction-intake stroke The induction stroke is the first phase in a four-stroke (e.g. Otto cycle or Diesel cycle) engine. It involves the downward movement of the piston, creating a partial vacuum that draws a air-fuel mixture (or air alone, in the case of a direct injection engine) into the combus ...

Cylinder Bore
In a piston engine, the bore (or cylinder bore) is the diameter of each cylinder. Engine displacement is calculated based on bore, stroke length and the number of cylinders: displacement = The stroke ratio, determined by dividing the bore by the stroke, traditionally indicated whether an engine was designed for power at high engine speeds (rpm) or torque at lower engine speeds. The term "bore" can also be applied to the bore of a locomotive cylinder or steam engine pistons. Steam locomotive The term bore also applies to the cylinder of a steam locomotive or steam engine. See also * Bore pitch * Compression ratio * 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 a loose indicator of the ... References {{Steam engine configurations Engine technology ...

Revolutions Per Minute
Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or with the notation min−1) is a unit of rotational speed or rotational frequency for rotating machines. Standards ISO 80000-3:2019 defines a unit of rotation as the dimensionless unit equal to 1, which it refers to as a revolution, but does not define the revolution as a unit. It defines a unit of rotational frequency equal to s−1. The superseded standard ISO 80000-3:2006 did however state with reference to the unit name 'one', symbol '1', that "The special name revolution, symbol r, for this unit is widely used in specifications on rotating machines." The International System of Units (SI) does not recognize rpm as a unit, and defines the unit of frequency, Hz, as equal to s−1. :\begin 1~&\text &&=& 60~&\text \\ \frac~&\text &&=& 1~&\text \end A corresponding but distinct quantity for describing rotation is angular velocity, for which the SI unit is the ra ...

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 a loose indicator of the power 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 engine. The formula is: : \text = \text \times \frac \times ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Straight-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 ...

Dual 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 en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
