Rolls-Royce C Range Engines
The Rolls-Royce ''C range'' was a series of in-line 4, 6 and 8 cylinder diesel engines used in small locomotives, railcars, construction vehicles, and marine and similar applications. They were manufactured by the Rolls-Royce Oil Engine Division headed by William Arthur Robotham to 1963, initially at Derby and later at Shrewsbury, from the 1950s through to 1970s. Although officially termed the ''C range'', they were best known for the most common C6SFL six-cylinder variant. Most had an output of around 200 bhp, with 233 bhp for the final models. Their construction was a conventional water-cooled vertical inline 6 four-stroke diesel engine of . Most were supercharged by a Roots blower, but there were also variants with a turbocharger or naturally aspirated. A later addition to the range was the SF65C model. This was a lower-rated version of the ''C'' range 6-cylinder engine and shared many of the advantages of the range's component rationalisation. It was available ...

Rolls-Royce Limited
Rolls-Royce Limited was a British luxury car and later an aero-engine manufacturing business established in 1904 in Manchester by the partnership of Charles Rolls and Henry Royce. Building on Royce's good reputation established with his Crane (machine), cranes, they quickly developed a reputation for superior engineering by manufacturing luxury cars. The business was incorporated as "Rolls-Royce Limited" in 1906, and a new factory in Derby was opened in 1908. The First World War brought the company into manufacturing aero-engines. Joint development of jet engines began in 1940, and they entered production in 1944. Rolls-Royce has since built an enduring reputation for the development and manufacturing of engines for military and commercial aircraft. In the late 1960s, Rolls-Royce was adversely affected by the mismanaged development of its advanced Rolls-Royce RB211, RB211 jet engine and consequent cost over-runs, though it ultimately proved a great success. In 1971, the owners w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monobloc Engine
''Monobloc'' refers to a component that is made in one block or casting. A monobloc engine or en bloc engine is an internal-combustion piston engine some of whose major components (such as cylinder head, cylinder block, or crankcase) are formed, usually by casting, as a single integral unit, rather than being assembled later. This has the advantages of improving mechanical stiffness, and improving the reliability of the sealing between them. ''Monobloc'' techniques date back to the beginnings of the internal combustion engine. Use of this term has changed over time, usually to address the most pressing mechanical problem affecting the engines of its day. There have been three distinct uses of the technique: * Cylinder head and cylinder * Cylinder block * Cylinder block and crankcase In most cases, any use of the term describes single-unit construction that is opposed to the more common contemporary practice. Where the monobloc technique has later become the norm, the specific term ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prime Mover (locomotive)
In engineering, a prime mover is an engine that converts chemical energy of a fuel into useful work. In a locomotive, the prime mover is thus the source of power for its propulsion. In an engine-generator set, the engine is the prime mover, as distinct from the generator. Definition In a diesel-mechanical locomotive, the prime mover is the diesel engine that is mechanically coupled to the driving wheels (drivers). In a diesel-hydraulic locomotive, the prime mover is the diesel engine that powers the pumps of one or more torque converters mechanically coupled to the drivers. In a diesel-electric locomotive, the prime mover is the diesel engine that rotates the main generator responsible for producing electricity to power the traction motors that are geared to the drivers. The prime mover can also be a gas turbine instead of a diesel engine. In either case, the generator, traction motors and interconnecting apparatus are considered to be the power transmission system and not p ...

Steam Locomotive
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, Fuel oil, oil or, rarely, Wood fuel, wood) to heat water in the locomotive's Boiler (power generation), boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its Steam locomotive components, cylinders in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a Tender (rail), tender coupled to it. #Variations, Variations in this general design include electrically powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom of Great Britain an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Wagon
A steam wagon (or steam lorry, steam waggon or steamtruck) is a Steam power, steam-powered truck for carrying freight. It was the earliest form of lorry (truck) and came in two basic forms: ''overtype'' and ''undertype'', the distinction being the position of the steam engine, engine relative to the boiler. Manufacturers tended to concentrate on one form or the other. Steam wagons were a widespread form of powered road traction for commercial haulage in the early part of the twentieth century, although they were a largely British phenomenon, with few manufacturers outside Great Britain. Competition from internal-combustion engine, internal-combustion-powered vehicles and adverse legislation meant that few remained in commercial use beyond the Second World War. Although the majority of steam wagons have been scrapped, a significant number have been preserved in working order and may be seen in operation at steam fairs, particularly in the UK. Design features The steam wagon came ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sentinel Waggon Works
Sentinel Waggon Works Ltd was a British company based in Shrewsbury, Shropshire that made steam-powered lorry, lorries (steam wagons), railway locomotives, and later, diesel engined lorries, buses and locomotives. History Alley & MacLellan, Sentinel Works, Jessie Street Glasgow Alley & MacLellan was founded in 1875 and was based in Polmadie, Glasgow. This company continued in operation until the 1950s. Initially manufacturing valves and compressors for steam engines, and later whole steamships, Alley & MacLellan acquired Simpson and Bibby of Horsehay, Shropshire, manufacturer of steam-powered road vehicles, in 1903. They began producing steam road vehicles in 1905 and in 1906 introduced a five-ton vertical-boiler steam wagon, which featured a two-cylinder undertype engine and chain drive. Around 1915, Alley & McLellan moved the steam wagon production to a new factory in Shrewsbury and it continued under a separate company (see below), and in 1918 the company also opened A ...

Diesel-hydraulic Locomotive
A diesel locomotive is a type of railway locomotive in which the power source is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. The most common are diesel–electric locomotives and diesel–hydraulic. Early internal combustion locomotives and railcars used kerosene and gasoline as their fuel. Rudolf Diesel patented his first compression-ignition engine in 1898, and steady improvements to the design of diesel engines reduced their physical size and improved their power-to-weight ratios to a point where one could be mounted in a locomotive. Internal combustion engines only operate efficiently within a limited power band, and while low-power gasoline engines could be coupled to mechanical transmissions, the more powerful diesel engines required the development of new forms of transmission. This is because clutches would need to be very large at these power leve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torsional Damper
A harmonic damper is a device fitted to the free (accessory drive) end of the crankshaft of an internal combustion engine to counter torsional and resonance vibrations from the crankshaft. This device must be an interference fit to the crankshaft in order to operate in an effective manner. An interference fit ensures the device moves in perfect step with the crankshaft. It is essential on engines with long crankshafts (such as straight-six or straight-eight engines) and V8 engines with cross plane cranks, or V6 and straight-three engines with uneven firing order. Harmonics and torsional vibrations can greatly reduce crankshaft life, or cause instantaneous failure if the crankshaft runs at or through an amplified resonance. Dampers are designed with a specific weight (mass) and diameter, which are dependent on the damping material/method used, to reduce mechanical Q factor, or damp, crankshaft resonances. A harmonic balancer (sometimes called crankshaft damper, torsional damper, o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Combustion Chamber
A combustion chamber is part of an internal combustion engine in which the air–fuel ratio, fuel/air mix is burned. For steam engines, the term has also been used for an extension of the Firebox (steam engine), firebox which is used to allow a more complete combustion process. Internal combustion engines In an internal combustion engine, the pressure caused by the burning air/fuel mixture applies direct force to part of the engine (e.g. for a piston engine, the force is applied to the top of the piston), which converts the gas pressure into mechanical energy (often in the form of a rotating output shaft). This contrasts an external combustion engine, where the combustion takes place in a separate part of the engine to where the gas pressure is converted into mechanical energy. Spark-ignition engines In spark ignition engines, such as petrol engine, petrol (gasoline) engines, the combustion chamber is usually located in the cylinder head. The engines are often designed such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuel Injection
Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of a fuel injector. This article focuses on fuel injection in reciprocating piston and Wankel rotary engines. All compression-ignition engines (e.g. diesel engines), and many spark-ignition engines (i.e. petrol (gasoline) engines, such as Otto or Wankel), use fuel injection of one kind or another. Mass-produced diesel engines for passenger cars (such as the Mercedes-Benz OM 138) became available in the late 1930s and early 1940s, being the first fuel-injected engines for passenger car use. In passenger car petrol engines, fuel injection was introduced in the early 1950s and gradually gained prevalence until it had largely replaced carburetors by the early 1990s. The primary difference between carburetion and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while carburetion relies on suction crea ...

Nitriding
Nitriding is a heat treating process that diffusion, diffuses nitrogen into the surface of a metal to create a case-hardening, case-hardened surface. These processes are most commonly used on low-alloy steels. They are also used on titanium, aluminium and molybdenum. Typical applications include gears, crankshafts, camshafts, cam followers, valve parts, extruder screws, die-casting tools, forging dies, extrusion dies, firearm components, injectors and plastic molding (process), mold tools. Processes The processes are named after the medium used to donate. The three main methods used are: ''gas nitriding'', ''salt bath nitriding'', and ''plasma nitriding''. Gas nitriding In gas nitriding the donor is a nitrogen-rich gas, usually ammonia (NH3), which is why it is sometimes known as ''ammonia nitriding''. When ammonia comes into contact with the heated work piece it dissociates into nitrogen and hydrogen. The nitrogen then diffuses onto the surface of the material creating a nitrid ...
