Mercedes-Benz M272 Engine
The Mercedes-Benz M272 engine is an automobile piston V6 engine family used in the 2000s (decade). Introduced in 2004, it is based on the M112 V6 introduced in 1998. All M272 engines have aluminum engine blocks with a 90° V-angle with silicon/aluminum lined cylinders. The aluminum DOHC cylinder heads have 4 valves per cylinder. All have forged steel connecting rods, one-piece cast crankshaft, iron-coated aluminum pistons and a magnesium intake manifold. Like the M112, a balance shaft is installed in the engine block between the cylinder banks to deal with vibrations in the 90 degree V6 design. This essentially eliminates first and second order moments. A dual-length Variable Length Intake Manifold is fitted to optimize engine flexibility. Continuous VVT was adopted for the first time. Featured on both the intake and exhaust camshafts, each can be varied through a range of 40 degrees. The twin spark plug system was replaced by a regular single spark plug per cylinder. New elect ...

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 integer number of AC cycles. Synchronous motors use electromagnets as the stator of the motor which create a magnetic field that rotates in time with the oscillations of the 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. Doubly fed synchronous motors use independently-excited multiphase AC electromagnets for both rotor and stator. Synchronous and induction motors are the most widely used AC motors. Synchronous motors rotate at a rate locked to the line frequency since they do not rely on induction to produce the rotor's magnetic field. Induction motors require '' slip'': the rotor must rotate at a frequency slightly slower than th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercedes-Benz OM629 Engine
The Mercedes-Benz OM629 is a diesel-fuelled, 4-stroke, compression-ignition internal combustion 75° 32-valve V8 engine used in the 2000s. __TOC__ Design The block features an aluminium crankcase and cylinder heads. It uses aluminium sand casting in bedplate construction (divided at the height of the crankshaft) with wet cylinder liner 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 e ...s made of cast iron. The main bearings are reinforced, cast in GGG ductile cast iron. Rather than the usual 90° " vee" angle between the cylinder banks, a 75° angle was chosen due to the space available to install the engine. The consequence of this specific angle is free inertial forces of the first order. To compensate for this, the OM628 and OM629 use a balancer shaft located in the vee o ...

Mercedes-Benz OM642 Engine
The Mercedes-Benz OM642 engine is a , 24-valve, aluminium/aluminium block and heads diesel 72° V6 engine manufactured by the Mercedes-Benz division of Daimler AG as a replacement for the Mercedes straight-5 and straight-6 cylinder engines. By 2010 a BlueTEC version of the Mercedes Sprinter OM642 was released. The BlueTEC systems allowed the elimination of much of the EGR in that vehicle's engine, which as a result gave compared to the non-BlueTec engine's . The engine features common rail Direct injection and a variable nozzle turbocharger. The injection system operates at , while the compression ratio is 18.0:1. The engine features a counter-rotating balance shaft mounted between the cylinder banks to cancel the vibrations inherent to the 72 degree V6 design, and the crankpins are offset by 48 degrees to achieve even 120 degree firing intervals. In some heavy vehicle applications, Mercedes' BlueTec AdBlue urea injection is utilised for NOx reduction. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
I4 Engine
A straight-four engine (also referred to as an inline-four engine) is a four-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. The majority of automotive four-cylinder engines use a straight-four layout (with the exceptions of the flat-four engines produced by Subaru and Porsche) and the layout is also very common in motorcycles and other machinery. Therefore the term "four-cylinder engine" is usually synonymous with straight-four engines. When a straight-four engine is installed at an inclined angle (instead of with the cylinders oriented vertically), it is sometimes called a slant-four. Between 2005 and 2008, the proportion of new vehicles sold in the United States with four-cylinder engines rose from 30% to 47%. By the 2020 model year, the share for light-duty vehicles had risen to 59%. Design A four-stroke straight-four engine always has a cylinder on its power stroke, unlike engines with fewer cylinders where there is no power st ...

Mercedes-Benz OM651 Engine
The OM651 is a family of inline-four cylinder automobile diesel engines introduced by Mercedes-Benz in 2008. Design The main goal was to create a common engine design that maximized the parts commonality across the engines manufactured by parent company, Daimler. One requirement of the design was the ability of the engine to be mounted both longitudinally and transversely. Improved fuel efficiency and compliance with Euro 5 emission standards were also design objectives, by 2010 being updated to the Euro 6 standard; four piezo-electric injectors fed with very high pressure fuel from a common rail inject fuel directly into the combustion chambers to improve combustion compared to previous Mercedes Diesel engines and recirculated exhaust gas reduces the oxygen in the cylinders to "starve" any reactions that would produce NO(x). There are 6 variants in all. Of these, 4 of the engine variants have the same 2.2 litre swept volume, tuned to different power outputs (badged x180 on ...

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.

Mercedes-Benz M275 Engine
The Mercedes-Benz M275 (and similar M285) engine is a twin-turbocharged and intercooled, all-aluminium, 60° V12 automobile piston engine family used in the 2000s to the 2010s. It is loosely based on the M137 naturally aspirated V12 sold between 1998 and 2002, and retains its SOHC, 3 valves per cylinder, twin- spark ignition layout, but differs with the addition of structural reinforcements to the engine block for improved rigidity which in turn yields greater reliability. The M275 V12 Bi-Turbo engine was modified with the addition of larger turbochargers. Several variations of the M275 V12 Bi-turbo engine have powered many top-of-the-range Mercedes-Benz and Maybach models since 2003. M275 Bore and stroke is giving a displacement of .

Mercedes-Benz M156 Engine
The M156 is the first automobile V8 engine designed autonomously by Mercedes-Benz subsidiary Mercedes-AMG, as previous AMG engines have always been based on original Mercedes engines. The engine was designed to be a naturally aspirated racing unit, and is also used in a number of high-performance AMG-badged Mercedes-Benz models. The engine was designed by Bernd Ramler, famed by the design of the Porsche Carrera GT's 5.7-liter V-10 engine. M156 The M156 displaces and shares very little with other Mercedes-Benz engine families like the M155. The bore spacing, block design, and other features are unique to the AMG engine. Although this engine displaces 6.2 litres, it is marketed as the "6.3" to commemorate Mercedes' famed 6.3 L M100 engine, its first production V8. The engine uses a bore and stroke of .
