BRM P25
The BRM P25 was a Formula One racing car raced from 1956 to 1960 and the second car produced by the British Racing Motors consortium. After the failure of the complex BRM V16, the P25's design emphasized simplicity. The car was fitted with a 2.5-litre straight-4 engine, producing some 275 horsepower. The P25 would be the foundation of BRM's successes in the late 1950s and early 1960s. Development With BRM in financial trouble after the V16 experiment, Alfred Owen purchased the team and set work on a new car. While the car was being developed, BRM ran a privateer Maserati 250F through the 1954 and 1955 seasons. Stewart Tresilian and Tony Rudd designed an entirely new twin-cam 2.5-litre four-cylinder for the P25. The engine's large bore allowed for larger valves to be fitted. In an exception to keeping with BRM's all-British supply policy, two Weber carburetors were fitted. The engine was mounted to a simple ladder frame steel chassis, with a centre tub monocoque section.

BRM P25 At Silverstone Classic 2011
British Racing Motors (BRM) was a British Formula One motor racing team. Founded in 1945 and based in the market town of Bourne in Lincolnshire, it participated from 1951 to 1977, competing in 197 grands prix and winning seventeen. BRM won the constructors' title in 1962 when its driver Graham Hill became world champion. In 1963, 1964, 1965 and 1971, BRM came second in the constructors' competition. History BRM was founded just after the Second World War by Raymond Mays, who had built several hillclimb and road racing cars under the ERA brand before the war, and Peter Berthon, a long-time associate. Mays' pre-war successes (and access to pre-war Mercedes-Benz and Auto Union design documents) inspired him to build an all-British grand prix car for the post-war era as a national prestige project, with financial and industrial backing from the British motor industry and its suppliers channelled through a trust fund. This proved to be an unwieldy way of organising and financi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trailing Arm
A (semi) trailing-arm suspension, sometimes referred to as (semi) trailing-link is a vehicle axle or wheel suspension design in which one or more horizontal arms (or "links"), perpendicular to and forward of the axle, are connecting the axle or wheels with pivot joint(s) ahead of them, on the structure (unibody or chassis) of a motor vehicle. These are typically used on the rear axle or wheels of a vehicle, but also found in aircraft landing gear. Leading arms are similar horizontal arms, perpendicular to the axle, but connecting the wheels to the vehicle structure via pivot joints ''to the rear'' of them. These are typically used on the front axle or wheels, as on the Citroën 2CV and its derivatives, and on the Citroën DS, as well as on the M422 Mighty Mite jeep. Types Trailing-arm Trailing-arm designs in live axle setups often use just two or three links and a Panhard rod to locate the wheel laterally. A trailing arm design can also be used in an independent suspen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BRM P15
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, la ...

Dunlop Rubber
Dunlop Ltd. (formerly Dunlop Rubber) was a British multinational company involved in the manufacture of various natural rubber goods. Its business was founded in 1889 by Harvey du Cros and he involved John Boyd Dunlop who had re-invented and developed the first pneumatic tyre. It was one of the first multinationals, and under du Cros and, after him, under Eric Geddes, grew to be one of the largest British industrial companies. J B Dunlop had dropped any ties to it well before his name was used for any part of the business. The business and manufactory was founded in Upper Stephens Street in Dublin. A plaque marks the site, which is now part of the head office of the Irish multinational departments store brand, Dunnes Stores. Dunlop Rubber failed to adapt to evolving market conditions in the 1970s, despite having recognised by the mid-1960s the potential drop in demand as the more durable Radial tire, radial tyres swept through the market.

Methanol
Methanol (also called methyl alcohol and wood spirit, amongst other names) is an organic chemical and the simplest aliphatic alcohol, with the formula C H3 O H (a methyl group linked to a hydroxyl group, often abbreviated as MeOH). It is a light, volatile, colourless, flammable liquid with a distinctive alcoholic odour similar to that of ethanol (potable alcohol). A polar solvent, methanol acquired the name wood alcohol because it was once produced chiefly by the destructive distillation of wood. Today, methanol is mainly produced industrially by hydrogenation of carbon monoxide. Methanol consists of a methyl group linked to a polar hydroxyl group. With more than 20 million tons produced annually, it is used as a precursor to other commodity chemicals, including formaldehyde, acetic acid, methyl tert-butyl ether, methyl benzoate, anisole, peroxyacids, as well as a host of more specialised chemicals. Occurrence Small amounts of methanol are present in normal, healthy hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gasoline
Gasoline (; ) or petrol (; ) (see ) is a transparent, petroleum-derived flammable liquid that is used primarily as a fuel in most spark-ignited internal combustion engines (also known as petrol engines). It consists mostly of organic compounds obtained by the fractional distillation of petroleum, enhanced with a variety of additives. On average, U.S. refineries produce, from a barrel of crude oil, about 19 to 20 gallons of gasoline; 11 to 13 gallons of distillate fuel (most of which is sold as diesel fuel); and 3 to 4 gallons of jet fuel. The product ratio depends on the processing in an oil refinery and the crude oil assay. A barrel of oil is defined as holding 42 US gallons, which is about 159 liters or 35 imperial gallons. The characteristic of a particular gasoline blend to resist igniting too early (which causes knocking and reduces efficiency in reciprocating engines) is measured by its octane rating, which is produced in several grades.

Differential (mechanical Device)
A differential is a gear train with three drive shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others, or a fixed multiple of that average. Functional description The following description of a differential applies to a traditional rear-wheel-drive car or truck with an open or limited slip differential combined with a reduction gearset using bevel gears (these are not strictly necessary; see spur-gear differential): Thus, for example, if the car is making a turn to the right, the main ring gear may make 10 full rotations. During that time, the left wheel will make more rotations because it has farther to travel, and the right wheel will make fewer rotations as it has less distance to travel. The sun gears (which drive the axle half-shafts) will rotate at different speeds relative to the ring gear (one faster, one slower) by, say, 2 full turns each (4 full turns relative to each other), resulting in the left wheel mak ...

Normally Aspirated Engine
Normality is a behavior that can be normal for an individual (intrapersonal normality) when it is consistent with the most common behavior for that person. Normal is also used to describe individual behavior that conforms to the most common behavior in society (known as conformity). However, normal behavior is often only recognized in contrast to abnormality. In many cases normality is used to make moral judgements, such that normality is seen as good while abnormality is seen as bad, or conversely normality can seen as boring and uninteresting. Someone being seen as normal or not normal can have social ramifications, such as being included, excluded or stigmatized by wider society. Measuring Many difficulties arise in measuring normal behaviors—biologists come across parallel issues when defining normality. One complication that arises regards whether 'normality' is used correctly in everyday language. People say "this heart is abnormal" if only a portion of it is not working ...

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 ...
