Synchronous Motor
A synchronous electric motor is an AC electric motor in which, at steady state, the rotation of the shaft is synchronized with the frequency of the supply current; the rotation period is exactly equal to an integral number of AC cycles. Synchronous motors contain multiphase AC electromagnets on the stator of the motor that create a magnetic field which rotates in time with the oscillations of the line current. The rotor with permanent magnets or electromagnets turns in step with the stator field at the same rate and as a result, provides the second synchronized rotating magnet field of any AC motor. A synchronous motor is termed ''doubly fed'' if it is supplied with independently excited multiphase AC electromagnets on both the rotor and stator. The synchronous motor and the induction motor are the most widely used types of AC motors. The difference between the two types is that the synchronous motor rotates at a rate locked to the line frequency since it does not rely on ...

Turbodiesel
The term turbo-diesel, also written as turbodiesel and turbo diesel, refers to any diesel engine equipped with a turbocharger. As with other engine types, turbocharging a diesel engine can significantly increase its efficiency and power output, especially when used in combination with an intercooler. Turbocharging of diesel engines began in the 1920s with large marine and stationary engines. Trucks became available with turbo-diesel engines in the mid-1950s, followed by passenger cars in the late 1970s. Since the 1990s, the compression ratio of turbo-diesel engines has been dropping. Principle Diesel engines are typically well suited to turbocharging due to two factors: * A "lean" air–fuel ratio, caused when the turbocharger supplies excess air into the engine, is not a problem for diesel engines, because the torque control is dependent on the mass of fuel that is injected into the combustion chamber (i.e. air-fuel ratio), rather than the quantity of the air-fuel mixture. ...

Mercedes-Benz OM656 Engine
The OM656 is a turbocharged diesel engine produced by Mercedes-Benz since 2017. It was first introduced in the facelift W222 S-Class. Design The OM656 is based on a modular design that is shared with other 4-cylinder and 6-cylinder, petrol and diesel engines. It is the replacement to the previous V6, in order to maintain the cost of production between different engines. The OM656 has dual overhead camshafts with variable valve timing, and uses AdBlue injection and exhaust gas recirculation In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide () emissions reduction technique used in petrol/gasoline, diesel engines and some hydrogen engines. EGR works by recirculating a portion of an engine's exhaust ... to reduce emissions.

Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercedes-Benz M177 Engine
The M176/M177/M178 is a V8 petrol engine range designed by Mercedes-AMG, replacing Mercedes-Benz M278 engine and Mercedes-Benz M157 engine, and is based on the Mercedes-Benz M133 engine. The engine has two BorgWarner turbochargers positioned between the two cylinder heads in a "hot-V" configuration. The fuel injection system uses Bosch's new piezo-electric direct fuel injectors that deliver five squirts of fuel per combustion cycle. The M176 engines are mostly assembled by machine with some components assembled by technicians at Untertürkheim manufacturing centre outside Stuttgart. The M177 and M178 are individually assembled by the technicians in "one man, one engine" principle at AMG manufacturing centre in Affalterbach. M176 The M176 version debuted in 2015 for the Mercedes-Benz G 500/G 550 and G 500 4x42. In 2019, M176 was equipped with EQ Boost mild hybrid 48V electrical system, producing additional output and of torque. This mild hybrid system was fitted to GLE 58 ...

Plug-in Hybrid
A plug-in hybrid electric vehicle (PHEV) is a hybrid electric vehicle whose battery pack can be recharged by plugging a charging cable into an external electric power source, in addition to internally by its on-board internal combustion engine-powered generator. Most PHEVs are passenger cars, but there are also PHEV versions of commercial vehicles and vans, utility trucks, buses, trains, motorcycles, mopeds, and even military vehicles. Similar to all-electric vehicles (BEVs), PHEVs displace greenhouse gas emissions from the car tailpipe exhaust to the power station generators powering the electricity grid. These centralized generators may be of renewable energy (e.g. solar, wind or hydroelectric) and largely emission-free, or have an overall lower emission intensity than individual internal combustion engines. Compared to conventional hybrid electric vehicles (HEVs), PHEVs have a larger battery pack that can be charged from the power grid, which is also more efficient ...

V12 Engine
A V12 engine is a twelve-cylinder piston engine where two banks of six cylinders are arranged in a 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 racing boats. Due to the balanced nature of the engine and the smooth delivery of power, V12 engines were found in early luxury automobiles, boats, aircraft, and tanks. Aircraft V12 engines reached their apogee during World War II, following 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. Design Balance and smoothness Each bank of a V12 engine essentially functions as a straight-six engine, which by itself has perfect primary and ...

Twin-turbo
Twin-turbo (not to be confused with a twincharger setup, which is a combination of a supercharger and a turbocharger) refers to an engine in which two turbochargers work in tandem to compress the intake fuel/air mixture (or intake air, in the case of a direct-injection engine). The most common layout features two identical or mirrored turbochargers in parallel, each processing half of a V engine's produced exhaust through independent piping. The two turbochargers can either be matching or different sizes. Types and combinations There are three types of turbine setups used for twin-turbo setups: * Parallel * Sequential * Series These can be applied to any of the five types of compressor setups (which theoretically could have 15 different setups): * Compound Compressors * Staged Compound Compressors * Staged Sequential Compressors * Parallel Sequential Compressors * Parallel Compressors Parallel A parallel configuration refers to using two equally-sized turbochargers which ...

V8 Engine
A V8 engine is an eight-cylinder piston engine in which two banks of four cylinders share a common crankshaft and are arranged in a V configuration. The first V8 engine was produced by the French Antoinette company in 1904, developed and used in cars and speedboats but primarily aircraft; while the American 1914–1935 ''Cadillac L-Head'' engine is considered the first road going V8 engine to be mass produced in significant quantities. The popularity of V8 engines in cars was greatly increased following the 1932 introduction of the ''Ford Flathead V8''. In the early 21st century, use of V8 engines in passenger vehicles declined as automobile manufacturers opted for more fuel efficient, lower capacity engines, or hybrid and electric drivetrains. Design V-angle The majority of V8 engines use a V-angle (the angle between the two banks of cylinders) of 90 degrees. This angle results in good engine balance, which results in low vibrations; however, the downside is a larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
