Engine Block
In an internal combustion engine, the engine block is the structure that contains the cylinders and other components. The engine block in an early automotive engine consisted of just the cylinder block, to which a separate crankcase was attached. Modern engine blocks typically have the crankcase integrated with the cylinder block as a single component. Engine blocks often also include elements such as coolant passages and oil galleries. The term "cylinder block" is often used interchangeably with "engine block". However, technically, the block of a modern engine (i.e., multiple cylinders integrated with another component) would be classified as a monobloc. __TOC__ Construction The main structure of an engine typically consists of the cylinders, coolant passages, oil galleries, crankcase, and cylinder head(s). The first production engines of the 1880s to 1920s usually used separate components for each element, which were bolted together during engine assembly. Modern en ...

Cylinder Block For V6 Diesel
A cylinder () has traditionally been a three-dimensional solid, one of the most basic of curvilinear geometric shapes. In elementary geometry, it is considered a prism with a circle as its base. A cylinder may also be defined as an infinite curvilinear surface in various modern branches of geometry and topology. The shift in the basic meaning—solid versus surface (as in a solid ball versus sphere surface)—has created some ambiguity with terminology. The two concepts may be distinguished by referring to solid cylinders and cylindrical surfaces. In the literature the unadorned term "cylinder" could refer to either of these or to an even more specialized object, the '' right circular cylinder''. Types The definitions and results in this section are taken from the 1913 text ''Plane and Solid Geometry'' by George A. Wentworth and David Eugene Smith . A ' is a surface consisting of all the points on all the lines which are parallel to a given line and which pass through ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crankshaft
A crankshaft is a mechanical component used in a reciprocating engine, piston engine to convert the reciprocating motion into rotational motion. The crankshaft is a rotating Shaft (mechanical engineering), shaft containing one or more crankpins, that are driven by the pistons via the connecting rods. The crankpins are also called ''rod bearing journals'', and they rotate within the "big end" of the connecting rods. Most modern crankshafts are located in the engine block. They are made from steel or cast iron, using either a forging, casting (metalworking), casting or machining process. Design The crankshaft is located within the engine block and held in place via main bearings which allow the crankshaft to rotate within the block. The up-down motion of each piston is transferred to the crankshaft via connecting rods. A flywheel is often attached to one end of the crankshaft, in order to smoothen the power delivery and reduce vibration. A crankshaft is subjected to enormou ...

V12 Engine
A V12 engine is a twelve-Cylinder (engine), cylinder Internal combustion engine#Reciprocating engines, piston engine where two banks of six cylinders are arranged in a V engine, V configuration around a common crankshaft. V12 engines are more common than V10 engines. However, they are less common than V8 engines. The first V12 engine was built in 1904 for use in Boat racing, racing boats. Due to the balanced nature of the engine and the smooth delivery of Engine power, power, V12 engines were found in early luxury automobiles, boats, aircraft, and tanks. Aircraft V12 engines reached their apogee during World War II, after which they were mostly replaced by jet engines. In Formula One racing, V12 engines were common during the late 1960s and early 1990s. Applications of V12 engines in the 21st century have been as marine engines, in railway locomotives, as large stationary power as well as in some European sports and luxury cars.

Lancia
Lancia Automobiles S.p.A. () is an Italian car manufacturer and a subsidiary of Stellantis Europe, which is the European subsidiary of Stellantis. The present legal entity of Lancia was formed in January 2007 when its corporate parent reorganised its businesses, but its history is traced back to ''Lancia & C.'', a manufacturing concern founded in 1906 in Turin, Torino by Vincenzo Lancia (1881–1937) and Claudio Fogolin. It became part of Fiat in 1969. The brand is known for its strong rallying heritage, and technical innovations such as the Vehicle frame#Unibody, unibody chassis of the 1922 Lancia Lambda, Lambda and the five-speed gearbox introduced in the 1948 Lancia Ardea, Ardea. Despite not competing in the World Rally Championship since 1992, Lancia still holds more List of World Rally Championship Constructors' champions, Manufacturers' Championships than any other brand. Sales of Lancia-branded vehicles declined from over 300,000 annual units sold in 1990 to less than 100 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V Engine
A V engine, sometimes called a Vee engine, is a common configuration for internal combustion engines. It consists of two cylinder banks—usually with the same number of cylinders in each bank—connected to a common crankshaft. These cylinder banks are arranged at an angle to each other, so that the banks form a "V" shape when viewed from the front of the engine. V engines typically have a shorter length than equivalent inline engines, however the trade-off is a larger width. V6, V8 and V12 engines are the most common layout for automobile engines with 6, 8 or 12 cylinders respectively. History The first V engine, a two-cylinder V-twin, was designed by Wilhelm Maybach and used in the 1889 Daimler Stahlradwagen automobile. The first V8 engine was produced in 1903, in the form of the Antoinette engine designed by Léon Levavasseur for racing boats and airplanes. The first V12 engine was produced the following year by Putney Motor Works in London, again for use in raci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ford Model T
The Ford Model T is an automobile that was produced by the Ford Motor Company from October 1, 1908, to May 26, 1927. It is generally regarded as the first mass-affordable automobile, which made car travel available to middle-class Americans. The relatively low price was partly the result of Ford's efficient fabrication, including assembly line production instead of individual handcrafting. The savings from mass production allowed the price to decline from $780 in 1910 () to $290 in 1924 ($ in dollars). It was mainly designed by three engineers, Joseph A. Galamb (the main engineer), Eugene Farkas, and Childe Harold Wills. The Model T was colloquially known as the "Tin Lizzie". The Ford Model T was named the most influential car of the 20th century in the 1999 Car of the Century competition, ahead of the Mini, BMC Mini, Citroën DS, and Volkswagen Beetle. Ford's Model T was successful not only because it provided inexpensive transportation on a massive scale, but also becaus ...

Straight Engine
The straight engine (also called inline engine) is a configuration of multi-cylinder piston engine where all of the cylinders are arranged in a single row, rather than radially or in two or more cylinder banks. Design A straight engine is easier to build than an equivalent flat engine or V engine, as it uses one cylinder head rather than two. Inline engines are also narrower than flat engines or V engines; however, they are longer and can be taller. The engine balance characteristics of a straight engine depend on the number of cylinders and the firing interval. Slant engines and horizontally-mounted engines When a straight engine is mounted at an angle from the vertical it is called a ''slant engine''. Notable slant engines include the 1959-2000 Chrysler Slant-6 engine, 1961-63 Pontiac Trophy 4 engine and the 1968-1981 Triumph Slant-4 engine. Some buses and diesel multiple unit trains take this concept further by mounting the engines horizontally (i.e. with a slant ...

Water Jacket
A water jacket is a water-filled casing surrounding a device, typically a metal sheath having intake and outlet vents to allow water to be pumped through and circulated. The flow of water to an external heating or cooling device allows precise temperature control of the device. Applications Water jackets are often used for water cooling or heating. They are also used in laboratory glassware: Liebig, Graham, and Allihn condensers. Water jackets were used to cool the barrels of machine guns until several years after the First World War, but modern machine guns are air-cooled to conserve weight and hence increase portability. In a reciprocating piston internal combustion engine, the water jacket is a series of holes either cast or bored through the main engine block and connected by inlet and outlet valves to a radiator. Equipment such as tissue culture incubators may be enclosed in a water jacket kept at a constant temperature. A water jacket is used in an Orsat analyzer t ...

Core (manufacturing)
A core is a device used in casting and molding (process), moulding processes to produce internal cavities and wikt:reentrant, reentrant angles (an interior angle that is greater than 180°). The core is normally a disposable item that is destroyed to get it out of the piece.. They are most commonly used in sand casting, but are also used in die casting and injection moulding. For example, cores define multiple passages inside cast engine blocks. One model of GM V-8 engine requires 5 dry-sand cores for every casting. Materials required to make cores *Core sand *Bentonite clay *Pulverized coal *Resin oil Advantages and disadvantages Cores are useful for features that cannot tolerate draft (engineering), draft or to provide detail that cannot otherwise be integrated into a core-less casting or mold. The main disadvantage is the additional cost to incorporate cores. Requirements There are seven requirements for cores: #Green strength: In the green condition, there must be adequate ...

Casting
Casting is a manufacturing process in which a liquid material is usually poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process. Casting materials are usually metals or various time setting materials that cure after mixing two or more components together; examples are epoxy, concrete, plaster and clay. Casting is most often used for making complex shapes that would be otherwise difficult or uneconomical to make by other methods. Heavy equipment like machine tool beds, ships' propellers, etc. can be cast easily in the required size, rather than fabricating by joining several small pieces. Casting is a 7,000-year-old process. The oldest surviving casting is a copper frog from 3200 BC. History Throughout history, metal casting has been used to make tools, weapons, and religious objects. Metal casting history and develo ...
