Straight-twelve Engine
A straight-12 engine or inline-12 engine is a twelve-cylinder piston engine with all twelve cylinders mounted in a straight line along the crankcase. Land use Due to the very long length of a straight-twelve engine, they are rarely used in automobiles. The first known example is a engine in the 1920 French ''Corona'' car; however it is not known if any cars were sold. Packard also experimented with an automobile powered by an inline 12 in 1929. The straight-12 has also been used for large military trucks. Marine use Some Russian firms built straight-12s for use in ships in the 1960s and 1970s.

Piston Engine
A reciprocating engine, more often known as a piston engine, is a heat engine that uses one or more Reciprocating motion, reciprocating pistons to convert high temperature and high pressure into a Circular motion, rotating motion. This article describes the common features of all types. The main types are: the internal combustion engine, used extensively in motor vehicles; the steam engine, the mainstay of the Industrial Revolution; and the Stirling engine for niche applications. Internal combustion engines are further classified in two ways: either a spark-ignition engine, spark-ignition (SI) engine, where the spark plug initiates the combustion; or a compression-ignition engine, compression-ignition (CI) engine, where the air within the cylinder is compressed, Adiabatic process, thus heating it, so that the heated air ignites fuel that is injected diesel engine, then or hot-bulb engine, earlier.''Thermodynamics: An Engineering Approach'' by Yunus A.

Cylinder (engine)
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 e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crankcase
A crankcase is the housing in a reciprocating engine, piston engine that surrounds the crankshaft. In most modern engines, the crankcase is integrated into the engine block. Two-stroke engines typically use a crankcase-compression design, resulting in the fuel/air mixture passing through the crankcase before entering the Cylinder (engine), cylinder(s). This design of the engine does not include an oil sump in the crankcase. Four-stroke engines typically have an oil sump at the bottom of the crankcase and the majority of the engine's oil is held within the crankcase. The fuel/air mixture does not pass through the crankcase, though a small amount of exhaust gasses often enter as "blow-by" from the combustion chamber, particularly in engines with worn rings. The crankcase often forms the upper half of the main bearing journals (with the bearing caps forming the other half), although in some engines the crankcase completely surrounds the main bearing journals. An ''open-crank'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Packard
Packard (formerly the Packard Motor Car Company) was an American luxury automobile company located in Detroit, Michigan. The first Packard automobiles were produced in 1899, and the last Packards were built in South Bend, Indiana, in 1958. One of the "Three Ps" – alongside Peerless Motor Company and Pierce-Arrow – the company was known for building high-quality luxury automobiles before World War II. Owning a Packard was considered prestigious, and surviving examples are often found in museums and automobile collections. Packard vehicles featured innovations, including the modern steering wheel, air-conditioning in a passenger car, and one of the first production 12-cylinder engines, adapted from developing the Liberty L-12 engine used during World War I to power warplanes. During World War II, Packard produced 55,523 units of the two-stage/two-speed supercharger equipped Merlin V-12s engines under contract with Rolls-Royce. Packard also made the versions of the Li ...

Wärtsilä-Sulzer RTA96-C
The Wärtsilä RT-flex96C is a two-stroke turbocharged low-speed diesel engine designed by the Finnish manufacturer Wärtsilä. It is designed for large container ships that run on heavy fuel oil. Its largest 14-cylinder version is high, long, weighs over , and produces . It is the largest reciprocating engine in the world. The 14-cylinder version first entered commercial service in September 2006 aboard the '' Emma Mærsk''. The design is similar to the older RTA96C engine, but with common rail technology (in place of traditional camshaft, chain gear, fuel pump and hydraulic actuator systems). This provides maximum performance at lower revolutions per minute (rpm), reduces fuel consumption and emits lower levels of harmful emissions. The engine has crosshead bearings so the always-vertical piston rods create a tight seal under the pistons. Consequently, the lubrication of the engine is split: the cylinders and the crankcase use different lubricants, each being specia ...

Piston Engine Configurations
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 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 ports in the cylinder. __TOC__ Piston engines Internal combustion engines An 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 downwards through the connecting rod and onto the crankshaft. The connecting rod is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
12-cylinder Engines
1 (one, unit, unity) is a number, Numeral (linguistics), numeral, and glyph. It is the first and smallest Positive number, positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit (measurement), unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In Digital electronics, digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions. In math ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
