Piston
A piston is a component of reciprocating engines, reciprocating pumps, gas compressors, hydraulic cylinders and pneumatic cylinders, among other similar mechanisms. It is the moving component that is contained by a cylinder (engine), cylinder and is made gas-tight by piston rings. In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. In a pump, the function is reversed and force is transferred from the crankshaft to the piston for the purpose of compressing or ejecting the fluid in the cylinder. In some engines, the piston also acts as a valve by covering and uncovering Porting (engine)#Two-stroke porting, ports in the cylinder. __TOC__ Piston engines Internal combustion engines An internal combustion piston engine, internal combustion engine is acted upon by the pressure of the expanding combustion gases in the combustion chamber space at the top of the cylinder. This force then acts dow ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

1930s Aircraft Piston Engines
Year 193 ( CXCIII) was a common year starting on Monday of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

BMW 132
The BMW 132 was a nine-cylinder radial aircraft engine produced by BMW starting in 1933. Design and development BMW took over a license for manufacturing air-cooled radial engines from Pratt & Whitney on 3 January 1928. The nine-cylinder model Pratt & Whitney R-1690 Hornet was initially manufactured virtually unchanged under the designation BMW Hornet. Soon BMW embarked on its own development. The result was the BMW 132, essentially an improved version of the Hornet engine, that went into production in 1933. A number of different versions were built; aside from the carburetor designs used mainly in civilian aircraft, versions with direct fuel injection were manufactured for the German ''Luftwaffe''. The engines had a displacement of and generated from to depending on model. The 132 found widespread use in the transport role, remaining the primary powerplant of the Junkers Ju 52 for much of its life, turning the BMW 132 into one of the most important aircraft engines for ci ...

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 ...

87 Octane
An octane rating, or octane number, is a standard measure of a fuel's ability to withstand compression in an internal combustion engine without causing engine knocking. The higher the octane number, the more compression the fuel can withstand before detonating. Octane rating does not relate directly to the power output or the energy content of the fuel per unit mass or volume, but simply indicates the resistance to detonating under pressure without a spark. Whether a higher octane fuel improves or impairs an engine's performance depends on the design of the engine. In broad terms, fuels with a higher octane rating are used in higher-compression gasoline engines, which may yield higher power for these engines. The added power in such cases comes from the way the engine is designed to compress the air/fuel mixture, and not directly from the rating of the gasoline. In contrast, fuels with lower octane (but higher cetane numbers) are ideal for diesel engines because diesel engines (a ...

Savoia-Marchetti S
SIAI-Marchetti was an Italian aircraft manufacturer primarily active during the interwar period. History The original company was founded during 1915 as SIAI (''Società Idrovolanti Alta Italia'' – Seaplane Company of Upper Italy). As suggested by its name, the firm initially specialised in the manufacture of seaplanes, the vast majority of which were intended for the Italian armed forces. Perhaps its most prominent early aircraft was the SIAI S.16, a seaplane that had been configured to perform both aerial reconnaissance and bomber roles, but also proved itself quite capable of long-distance flights. During 1925, Italian aviator Francesco de Pinedo of the '' Regia Aeronautica'' (Italian Royal Air Force) used an SIAI S.16''ter'' he named ''Genariello'' for a record-setting flight from Rome to Australia and Tokyo to demonstrate his idea that seaplanes were superior to landplanes for long-distance flights. Having departed Rome on 21 April, Pinedo and his mechanic, Ernesto Campan ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
