TVR Speed Six
The TVR Speed Six was the name of a naturally aspirated straight-six engine manufactured from 1999 to 2007 by British car manufacturer TVR, and used in several of their cars including the Tuscan, Cerbera, Tamora, T350, Sagaris and Typhon. The engine's prototypes (referred to as AJP-6) were designed and delivered by independent engineer Al Melling (the "A" in AJP) as both 3.0 and 3.5 litre units. Many of its key cylinder head design elements (particularly the valvetrain) were first seen in the 1991 Suzuki GSX-R750 (M) motorcycle engine (also a Melling design). The key design features were an all aluminium alloy block and head, with cast iron cylinder liners, double overhead camshafts, finger follower 24-valve actuation, one throttle and injector per cylinder ( throttle-body fuel injection), equal length tubular exhaust manifolds dual 3-way catalytic converters and a dry sump lubrication system allowing the engine to be mounted lower in the vehicle chassis.

Naturally Aspirated
A naturally aspirated engine, also known as a normally aspirated engine, and abbreviated to N/A or NA, is an internal combustion engine in which air intake depends solely on atmospheric pressure and does not have forced induction through a turbocharger or a supercharger. Description In a naturally aspirated engine, air for combustion (Diesel cycle in a diesel engine or specific types of Otto cycle in petrol engines, namely Gasoline direct injection, petrol direct injection) or an air/fuel mixture (traditional Otto cycle petrol engines), is drawn into the engine's cylinder (engine), cylinders by atmospheric pressure acting against a Vacuum, partial vacuum that occurs as the piston travels downwards toward Dead centre (engineering), bottom dead centre during the intake stroke (engine), stroke. Owing to innate restriction in the engine's inlet tract, which includes the Inlet manifold, intake manifold, a small pressure drop occurs as air is drawn in, resulting in a volumetric effici ...

Dry Sump
A dry sump system is a method to manage the lubricating motor oil in Four-stroke engine, four-stroke and large Two-stroke engine, two-stroke Reciprocating engine, reciprocating internal combustion engines. The dry sump system uses two or more oil pump (internal combustion engine), oil pumps and a separate oil reservoir, as opposed to a conventional wet sump system, which uses only the main sump (American English, U.S.: oil pan) below the engine and a single pump. A dry sump engine requires a Relief valve, pressure relief valve to regulate negative pressure inside the engine so that internal seals are not inverted. Dry sump lubrication is common on larger diesel engines such as those used in ships, as well as gasoline engines used in Auto racing, racing cars, Aerobatics, aerobatic aircraft, high-performance personal watercraft, and Motorcycle, motorcycles. Dry sumps may be chosen for these applications due to increased reliability, oil capacity, reduction of oil starvation under ...

Catalytic Converter
A catalytic converter part is an vehicle emissions control, exhaust emission control device which converts toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalysis, catalyzing a redox chemical reaction, reaction. Catalytic converters are usually used with internal combustion engines fueled by gasoline or diesel fuel, diesel, including lean-burn engines, and sometimes on kerosene heaters and stoves. The first widespread introduction of catalytic converters was in the United States automobile market. To comply with the United States Environmental Protection Agency, U.S. Environmental Protection Agency's stricter regulation of exhaust emissions, most gasoline-powered vehicles starting with the 1975 model year are equipped with catalytic converters. These "two-way" oxidation converters combine oxygen with carbon monoxide (CO) and unburned hydrocarbons (HC) to produce carbon dioxide (CO2) and water (H2O). "Three-way" conve ...

Exhaust Manifold
In automotive engineering, an exhaust manifold collects the exhaust gases from multiple cylinders into one pipe. The word ''manifold'' comes from the Old English word ''manigfeald'' (from the Anglo-Saxon ''manig'' anyand ''feald'' old and refers to the folding together of multiple inputs and outputs (in contrast, an inlet or intake manifold ''supplies'' air ''to'' the cylinders). Exhaust manifolds are generally simple cast iron or stainless steel units which collect engine exhaust gas from multiple cylinders and deliver it to the exhaust pipe. For many engines, there are aftermarket tubular exhaust manifolds known as headers in American English, as extractor manifolds in British and Australian English, and simply as "tubular manifolds" in British English. These consist of individual exhaust headpipes for each cylinder, which then usually converge into one tube called a collector. Headers that do not have collectors are called zoomie headers. The most common types of afterm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Throttle-body Fuel Injection
Manifold injection is a mixture formation system for internal combustion engines with external mixture formation. It is commonly used in engines with spark ignition that use petrol as fuel, such as the Otto engine, and the Wankel engine. In a manifold-injected engine, the fuel is injected into the intake manifold, where it begins forming a combustible air-fuel mixture with the air. As soon as the intake valve opens, the piston starts sucking in the still forming mixture. Usually, this mixture is relatively homogeneous, and, at least in production engines for passenger cars, approximately stoichiometric; this means that there is an even distribution of fuel and air across the combustion chamber, and enough, but not more air present than what is required for the fuel's complete combustion. The injection timing and measuring of the fuel amount can be controlled either mechanically (by a fuel distributor), or electronically (by an engine control unit). Since the 1970s and 1980s, manifold ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Throttle
A throttle is a mechanism by which fluid flow is managed by construction or obstruction. An engine's power can be increased or decreased by the restriction of inlet gases (by the use of a throttle), but usually decreased. The term ''throttle'' has come to refer, informally, to any mechanism by which the power or speed of an engine is regulated, such as a car's accelerator pedal. What is often termed a ''throttle'' (in an aviation context) is also called a thrust lever, particularly for jet engine powered aircraft. For a steam locomotive, the valve which controls the steam is known as the regulator. Internal combustion engines In an internal combustion engine, the throttle is a means of controlling an engine's power by regulating the amount of fuel or air entering the engine. In a motor vehicle the control used by the driver to regulate power is sometimes called the throttle, accelerator, or gas pedal. For a gasoline engine, the throttle most commonly regulates the amount of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double Overhead Camshaft
An overhead camshaft (OHC) engine is a piston engine in which 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cylinder Liner
In an engine, the cylinder is the space in which a piston travels. The inner surface of the cylinder is formed from either a thin metallic liner (also called "sleeve") or a surface coating applied to the engine block. A piston is seated inside each cylinder by several metal piston rings, which also provide seals for compression and the lubricating oil. The piston rings do not actually touch the cylinder walls, instead they ride on a thin layer of lubricating oil. Steam engines The cylinder in a steam engine is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were cast in cast iron and later in steel. The cylinder casting can include other features such as valve ports and mounting feet. Internal combustion engines The cylinder is the space through which the piston travels, propelled by the energy generated from the combustion of the air/fuel mixture in the combustion chamber. In an air-cooled engine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content of more than 2% and silicon content around 1–3%. Its usefulness derives from its relatively low melting temperature. The alloying elements determine the form in which its carbon appears: Cast iron#White cast iron, white cast iron has its carbon combined into an iron carbide named cementite, which is very hard, but brittle, as it allows cracks to pass straight through; Grey iron, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and Ductile iron, ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable iron, malleable cast irons. With its relatively low melting point, g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminium Alloy
An aluminium alloy ( UK/IUPAC) or aluminum alloy ( NA; see spelling differences) is an alloy in which aluminium (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, tin, nickel and zinc. There are two principal classifications, namely casting alloys and wrought alloys, both of which are further subdivided into the categories heat-treatable and non-heat-treatable. About 85% of aluminium is used for wrought products, for example rolled plate, foils and extrusions. Cast aluminium alloys yield cost-effective products due to their low melting points, although they generally have lower tensile strengths than wrought alloys. The most important cast aluminium alloy system is Al–Si, where the high levels of silicon (4–13%) contribute to give good casting characteristics. Aluminium alloys are widely used in engineering structures and components where light weight or corrosion resistance is required.I. J. Polmear, ''Light Alloys'', A ...

Suzuki GSX-R750
The Suzuki GSX-R750 is a sports motorcycle made by Suzuki since 1984. It was introduced at the Intermot, Cologne Motorcycle Show in October 1984 as a motorcycle of the Suzuki GSX-R Series, GSX-R series for the 1985 model year. Air and oil cooled The air and oil-cooled models can be divided into the first-generation and the second-generation colloquially referred to as 'slabbies' and 'slingshots' respectively. The 1985-1987 models featured very flat bodies compared to modern sport-bikes, hence the term 'slab-sided'. 1988-1991 (1992 USA) models are sometimes referred to as slingshots because the carburetors introduced in 1988 were marketed as slingshot carburetors (slingshot describes the cross-section of the semi-flat slide carbs). GSX-R750 (F) 1985 (The Classic) The original model featured a lightweight aluminum alloy frame, flat slide Mikuni VM29SS carburettors, twin discs with 4-pot calipers, and tyres both front and rear. To save weight, the designers specified an air-and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
