Mercedes-Benz M196 Engine
The Mercedes-Benz M 196 engine is a naturally-aspirated, straight-8, racing engine, designed, developed, and produced by Daimler-Benz; and used in both sports car racing and Formula One racing, between 1954 and 1955. Daimler-Benz made two versions of the engine, the M 196 R, displacing 2.5 litres, and the M 196 S, displacing 3.0 litres. Mercedes pulled out of all motorsports after the 1955 Le Mans disaster. This was their last Formula One engine, and Mercedes did not return to motorsport as an engine manufacturer until , when they supplied engines to the Sauber Formula One team. M 196 R The new 1954 Formula One rules allowed a choice of naturally aspirated engines – up to 2.5 litres or 0.75 litres supercharged. The expected target range for competitive engines was . By its introduction at the 1954 French GP the (76.0×68.8 mm) desmodromic valves straight 8 M 196 R delivered . The M 196 was the only F1 engine with dir ...

Formula One
Formula One (also known as Formula 1 or F1) is the highest class of international racing for open-wheel single-seater formula racing cars sanctioned by the Fédération Internationale de l'Automobile (FIA). The World Drivers' Championship, which became the FIA Formula One World Championship in 1981, has been one of the premier forms of racing around the world since its inaugural season in 1950. The word ''formula'' in the name refers to the set of rules to which all participants' cars must conform. A Formula One season consists of a series of races, known as ''Grands Prix'', which take place worldwide on both purpose-built circuits and closed public roads. A points system is used at Grands Prix to determine two annual World Championships: one for drivers, the other for constructors. Each driver must hold a valid Super Licence, the highest class of racing licence issued by the FIA. The races must run on tracks graded "1" (formerly "A"), the highest grade-rating issued ...

Mercedes-Benz W196
The Mercedes-Benz W196 was a Formula One racing car produced by Mercedes-Benz for the and F1 seasons. Successor to the W194, in the hands of Juan Manuel Fangio and Stirling Moss it won 9 of 12 races entered and captured the only two world championships in which it competed. Firsts included the use of desmodromic valves and Daimler-Benz developed mechanical direct fuel injection adapted from the DB 601 high-performance V12 used on the Messerschmitt Bf 109E fighter during World War II. The legendary 3-liter 300 SLR (''Sport Leicht-Rennen'', eng: ''Sport Light-Racing'') was derived from the W196 for the 1955 World Sportscar Championship season. Its crash at Le Mans that year ended not only its own short-lived domination on the WSC circuit but spelled the end also for the W196, as Mercedes pulled out of competitive racing in 1955 and did not return for another three decades.

Ignition Magneto
An ignition magneto, or high-tension magneto, is a magneto that provides current for the ignition system of a spark-ignition engine, such as a petrol engine. It produces pulses of high voltage for the spark plugs. The older term ''tension'' means ''voltage''. The use of ignition magnetos is now confined mainly to engines where there is no other available electrical supply, for example in lawnmowers and chainsaws. It is also widely used in aviation piston engines even though an electrical supply is usually available. In this case, the magneto's self-powered operation is considered to offer increased reliability; in theory, the magneto should continue operation as long as the engine is turning. History Firing the gap of a spark plug, particularly in the combustion chamber of a high-compression engine, requires a greater voltage (or ''higher tension'') than can be achieved by a simple magneto. The ''high-tension magneto'' combines an alternating current magneto generat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gasoline Direct Injection
Gasoline direct injection (GDI), also known as petrol direct injection (PDI), is a mixture formation system for internal combustion engines that run on gasoline (petrol), where fuel is injected into the combustion chamber. This is distinct from manifold fuel injection systems, which inject fuel into the intake manifold. The use of GDI can help increase engine efficiency and specific power output as well as reduce exhaust emissions. The first GDI engine to reach production was introduced in 1925 for a low-compression truck engine. Several German cars used a Bosch mechanical GDI system in the 1950s, however usage of the technology remained rare until an electronic GDI system was introduced in 1996 by Mitsubishi for mass-produced cars. GDI has seen rapid adoption by the automotive industry in recent years, increasing in the United States from 2.3% of production for model year 2008 vehicles to approximately 50% for model year 2016.

Hirth Joint
A Hirth joint or Hirth coupling is a type of mechanical connection named after its developeAlbert Hirth It is used to connect two pieces of a shaft together and is characterized by tapered teeth that mesh together on the end faces of each half shaft. Construction Hirth joints consist of radial teeth formed by grooves milled or ground into the end face of a cylindrical shaft. The teeth mesh around a ring, as the torque capacity of teeth increases with their diameter. This ring is arranged to be at the maximal possible diameter for the space available. The centre of a shaft is not toothed, as this would add little torque capacity to the coupling and the increasingly narrow teeth would become impractical to cut. For instance, a shaft of 60 mm diameter can be toothed in a 12 mm wide ring only (inner diameter is 36 mm) without jeopardizing the load-bearing capacity of the shaft. Tapered, symmetrical serrations are used. Profile angles of 60 and 90 degrees are used. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminium
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity tow ...

Chromium
Chromium is a chemical element with the symbol Cr and atomic number 24. It is the first element in group 6. It is a steely-grey, lustrous, hard, and brittle transition metal. Chromium metal is valued for its high corrosion resistance and hardness. A major development in steel production was the discovery that steel could be made highly resistant to corrosion and discoloration by adding metallic chromium to form stainless steel. Stainless steel and chrome plating ( electroplating with chromium) together comprise 85% of the commercial use. Chromium is also greatly valued as a metal that is able to be highly polished while resisting tarnishing. Polished chromium reflects almost 70% of the visible spectrum, and almost 90% of infrared light. The name of the element is derived from the Greek word χρῶμα, ''chrōma'', meaning color, because many chromium compounds are intensely colored. Industrial production of chromium proceeds from chromite ore (mostly FeCr2O4) to produce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silumin
Silumin is a general name for a group of lightweight, high-strength aluminium alloys based on an aluminum–silicon system. Aluminium-silicon alloys typically contain 3 to 25% silicon content. Casting is the primary use of aluminum-silicon alloys, but they can also be utilized in rapid solidification processes and powder metallurgy. Alloys used by powder metallurgy, rather than casting, may contain even more silicon, up to 50%. Silumin has a high resistance to corrosion, making it useful in humid environments. The addition of silicon to aluminum also makes it less viscous when in liquid form, which, together with its low cost (as both component elements are relatively cheap to extract), makes it a very good casting alloy. Silumin with good castability may give a stronger finished casting than a potentially stronger alloy that is more difficult to cast. Hypereutectic alloys, with a silicon content of 16 to 19%, such as Alusil, can be used in high-wear applications such as pistons, ...

BMEP
The mean effective pressure (MEP) is a quantity relating to the operation of a reciprocating engine and is a measure of an engine's capacity to do work that is independent of engine displacement.Heywood, J. B., "Internal Combustion Engine Fundamentals", McGraw-Hill Inc., 1988, p. 50 When quoted as an ''indicated mean effective pressure'' (''IMEP''), it may be thought of as the average pressure acting on a piston during the different portions of its cycle. Derivation Let: :W = work per cycle in joule; :P = power output in watt; :p_\text = mean effective pressure in pascal; :V_\text = displacement volume in cubic metre; :n_\text = number of revolutions per power stroke (for a 4-stroke engine, n_\text =2);Wankel engines are four-stroke engines, so n_\text =2; the displacement V_\text is derived from the chamber volume V_\text by multiplying it with the number of rotary pistons i and 2: V_\text = 2 V_\text i (see Wolf-Dieter Bensinger: ''Rotationskolben-Verbrennungsmotoren'', Sprin ...

Mercedes-Benz 300 SLR
The Mercedes-Benz 300 SLR (W 196 S) was a 2-seat sports racing car that took part in the 1955 World Sportscar Championship before a catastrophic crash and fire at Le Mans later that year ended its domination prematurely. The car was designated "SL-R" (for ''Sport Leicht-Rennen'', eng: ''Sport Light-Racing''), which was later condensed to "SLR". Technically, the W 196 S is based on the W 196 R, but has a slightly different engine, displacing 3 litres. Just as the W 196 R Formula One racer's M 196 R engine, the W 196 S's M 196 S engine is a direct-injected 3-litre straight 8 engine (but with a 78 mm bore and stroke); its rated power is . The W 196 S's '' monoposto'' driving position was modified to standard two-abreast seating, headlights were added, and a few other changes made to adapt a strictly track competitor to a 24-hour road/track sports racer.
