F-head
The intake/inlet over exhaust, or "IOE" engine, known in the US as F-head, is a four-stroke internal combustion engine whose valvetrain comprises OHV inlet valves within the cylinder head and exhaust side-valves within the engine block.V.A.W Hillier: ''Fundamentals of Motor Vehicle Technology'', 4th edition, Standly Thornes, Cheltenham 1991, , p. 39+40 IOE engines were widely used in early motorcycles, initially with the inlet valve being operated by engine suction instead of a cam-activated valvetrain. When the suction-operated inlet valves reached their limits as engine speeds increased, the manufacturers modified the designs by adding a mechanical valvetrain for the inlet valve. A few automobile manufacturers, including Willys, Rolls-Royce and Humber also made IOE engines for both cars and military vehicles. Rover manufactured inline four and six cylinder engines with a particularly efficient version of the IOE induction system. A few designs with the reverse system, exhaus ...

Flathead Engine
A flathead engine, also known as a sidevalve engine''American Rodder'', 6/94, pp.45 & 93. or valve-in-block engine is an internal combustion engine with its poppet valves contained within the engine block, instead of in the cylinder head, as in an overhead valve engine. Flatheads were widely used internationally by automobile manufacturers from the late 1890s until the mid-1950s but were replaced by more efficient overhead valve and overhead camshaft engines. They are currently experiencing a revival in low-revving aero-engines such as the D-Motor. The side-valve design The valve gear comprises a camshaft sited low in the cylinder block which operates the poppet valves via tappets and short pushrods (or sometimes with no pushrods at all). The flathead system obviates the need for further valvetrain components such as lengthy pushrods, rocker arms, overhead valves or overhead camshafts. The sidevalves are typically adjacent, sited on one side of the cylinder(s), though some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Willys
Willys (pronounced , "Willis" ) was a brand name used by Willys–Overland Motors, an American automobile company, founded by John North Willys. It was best known for its design and production of World War II era and later military jeeps (MBs), as well as civilian versions (Jeep CJs), and branding the 'jeep' military slang-word into the '(Universal)Jeep' marque. History Early history In 1908, John Willys bought the Overland Automotive Division of Standard Wheel Company and in 1912 renamed it Willys–Overland Motor Company. From 1912 to 1918, Willys was the second-largest producer of automobiles in the United States after Ford Motor Company. In 1913, Willys acquired a license to build Charles Yale Knight's sleeve-valve engine which it used in cars bearing the Willys–Knight nameplate. In the mid-1920s, Willys also acquired the F.B. Stearns Company of Cleveland and assumed continued production of the Stearns-Knight luxury car, as well. John Willys acquired the E ...

Octane
Octane is a hydrocarbon and an alkane with the chemical formula , and the condensed structural formula . Octane has many structural isomers that differ by the amount and location of branching in the carbon chain. One of these isomers, 2,2,4-Trimethylpentane, 2,2,4-trimethylpentane (commonly called iso-octane) is used as one of the standard values in the octane rating scale. Octane is a component of gasoline (petrol). As with all low-molecular-weight hydrocarbons, octane is volatility (chemistry), volatile and very flammable. Use of the term in gasoline "Octane" is colloquially used as a short form of "octane rating," particularly in the expression "high octane". "Octane rating" is an index of a fuel's ability to resist engine knock in engines having different compression ratios, which is a characteristic of octane's branched-chain isomers, especially iso-octane. The octane rating of gasoline is not directly related to the power output of an engine. Using gasoline of a higher o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rover (marque)
Rover is a British automotive marque that was used for over a century, from 1904 to 2005. It was launched as a bicycle maker called Rover Company in 1878, before starting to manufacture autocars in 1904. The brand used the iconic Viking longship as its logo. The rights to the marque are currently part of Jaguar Land Rover, but no Rover vehicles are currently in production and the marque is considered dormant. Despite a state-controlled absorption by the Leyland Motor Corporation (LMC) in 1967 and subsequent mergers, nationalisation, and demergers, the Rover marque retained its identity, first as an independent subsidiary division of LMC, and subsequently through various groups within British Leyland (BL) through the 1970s and into the 1980s. The Rover marque then became the flagship brand of the newly and eponymously renamed Rover Group in 1988, which included the actually stronger and more valuable brand names Land Rover and Mini as it passed first through the hands of Brit ...

Squish (piston Engine)
Squish is an effect in internal combustion engines which creates sudden turbulence of the air-fuel mixture as the piston approaches top dead centre (TDC)."The Combustion Chamber" Retrieved 16 June 2013. In an engine designed to use the squish effect, at top dead centre the piston crown comes very close (typically less than 1 mm) to the cylinder head. The gases are suddenly "squished" out within the , creating turbulence which promotes thorough air-fuel mixing, a factor beneficial to efficient . Squish effect may be found in |
Land Rover Series
The Land Rover series I, II, and III (commonly referred to as ''series'' Land Rovers, to distinguish them from later models) are compact British off-road vehicles, produced by the Rover Company since 1948, and later by British Leyland. Though inspired by the World War II jeep, the Land Rover immediately distinguished itself from all other cars. From launch, it was the first mass-produced civilian four-wheel drive car with doors on it, and an available hard roof. Contrary to conventional car and truck chassis, it used a sturdier fully box-welded frame. Furthermore, due to post-war steel shortage, and aluminium surplus, Land Rovers received non-rusting aluminium alloy bodies, favouring their longevity. In 1992, Land Rover claimed that 70% of all the vehicles they had built were still in use. Most series models feature leaf-spring suspension with selectable two or four-wheel drive (4WD), however series I's produced between 1948 and mid-1951 had constant 4WD via a freewheel mech ...

Inlet Over Exhaust
An inlet is a (usually long and narrow) indentation of a shoreline, such as a small arm, bay, sound, fjord, lagoon or marsh, that leads to an enclosed larger body of water such as a lake, estuary, gulf or marginal sea. Overview In marine geography, the term "inlet" usually refers to either the actual channel between an enclosed bay and the open ocean and is often called an "entrance", or a significant recession in the shore of a sea, lake or large river. A certain kind of inlet created by past glaciation is a fjord, typically but not always in mountainous coastlines and also in montane lakes. Multi-arm complexes of large inlets or fjords may be called sounds, e.g., Puget Sound, Howe Sound, Karmsund (''sund'' is Scandinavian for "sound"). Some fjord-type inlets are called canals, e.g., Portland Canal, Lynn Canal, Hood Canal, and some are channels, e.g., Dean Channel and Douglas Channel. Tidal amplitude, wave intensity, and wave direction are all factors that influ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pool Petrol
Rationing was introduced temporarily by the British government several times during the 20th century, during and immediately after a war. At the start of the Second World War in 1939, the United Kingdom was importing 20 million long tons of food per year, including about 70% of its cheese and sugar, almost 80% of fruit and about 70% of cereals and fats. The UK also imported more than half of its meat and relied on imported feed to support its domestic meat production. The civilian population of the country was about 50 million. It was one of the principal strategies of the Germans in the Battle of the Atlantic to attack shipping bound for Britain, restricting British industry and potentially starving the nation into submission. To deal with sometimes extreme shortages, the Ministry of Food instituted a system of rationing. To buy most rationed items, each person had to register at chosen shops and was provided with a ration book containing coupons. The shopkeeper was provide ...

Stroke Ratio
In a reciprocating piston engine, the stroke ratio, defined by either bore/stroke ratio or stroke/bore ratio, is a term to describe the ratio between cylinder bore diameter and piston stroke length. 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. A fairly comprehensive yet understandable study of stroke/bore effects was published in ''Horseless Age'', 1916. Conventions In a piston engine, there are two different ways of describing the ''stroke ratio'' of its cylinders, namely: ''bore/stroke'' ratio, and ''stroke/bore'' ratio. Bore/stroke ratio Bore/stroke is the more commonly used term, with usage in North America, Europe, United Kingdom, Asia, and Australia. The diameter of the cylinder bore is divided by the length of the piston stroke to give the rati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
