Mercedes-Benz M123 Engine
The M123 engine family was a straight-6 automobile engine from Mercedes-Benz, used from 1976 to 1984 in the W123 series models 250 and 250 T. It replaced the 6-cylinder engines M180 in the 230 and M130 in the 250 (2.8 liter) versions from the W114 series. The M123 was succeeded by the M103, introduced in 1984 with the M124 series. Characteristics Like the M180, the M123 only has four crankshaft bearings and its oil pump, fuel pump and distributor are driven by a shaft inclined at the front end of the motor, which in turn is driven through a sprocket and a helical gear pair. Unlike the M180's paired cylinder spacing, the M123’s is uniform like in the M130. So, instead of cooling ducts cast between the cylinders, slots in the cylinders’ partition walls are traversed by coolant. The engine has a single overhead camshaft (SOHC), driven by a chain. The vertical hanging valves are arranged in two rows, operated by rocker levers. As with the M115, inlet and outlet both are o ...

Mercedes-Benz W114
The Mercedes-Benz W114 and W115 were the internal designation Mercedes-Benz used for a generation of front-engine, rear-drive, five-passenger sedans and coupés introduced in 1968, with three-box styling by Paul Bracq — succeeding the W110 models introduced in 1961; and manufactured until model year 1976, when the W123 was released. W114/W115s were distinguished in the marketplace by nameplates relating to their engine size. W114 models featured six-cylinder engines and were marketed as the ''230'', ''250'', and ''280''. W115 models featured four-cylinder engines and were marketed as the ''200'', ''220'', ''230'', and ''240'', with diesel models carrying a ''D'' designation, as distinct from gasoline/petrol models. When Mercedes introduced the W114/115 in 1968, they marketed sedans in two size classes (W114/W115 and S-Class) and marketed the W114/115 range as ''New Generation Models'', ultimately the only model of the new generation. Mercedes used a '''/8''' on the W114 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spark Plug
A spark plug (sometimes, in British English, a sparking plug, and, colloquially, a plug) is a device for delivering electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark, while containing combustion pressure within the engine. A spark plug has a metal threaded shell, electrically isolated from a central electrode by a ceramic insulator. The central electrode, which may contain a resistor, is connected by a heavily insulated wire to the output terminal of an ignition coil or magneto. The spark plug's metal shell is screwed into the engine's cylinder head and thus electrically grounded. The central electrode protrudes through the porcelain insulator into the combustion chamber, forming one or more spark gaps between the inner end of the central electrode and usually one or more protuberances or structures attached to the inner end of the threaded shell and designated the ''side ...

Exhaust Valve
A poppet valve (also called mushroom valve) is a valve typically used to control the timing and quantity of gas or vapor flow into an engine. It consists of a hole or open-ended chamber, usually round or oval in cross-section, and a plug, usually a disk shape on the end of a shaft known as a valve stem. The working end of this plug, the valve face, is typically ground at a 45° bevel to seal against a corresponding valve seat ground into the rim of the chamber being sealed. The shaft travels through a valve guide to maintain its alignment. A pressure differential on either side of the valve can assist or impair its performance. In exhaust applications higher pressure against the valve helps to seal it, and in intake applications lower pressure helps open it. The poppet valve was invented in 1833 by American E.A.G. Young of the Newcastle and Frenchtown Railroad. Young had patented his idea, but the Patent Office fire of 1836 destroyed all records of it. Etymology The word p ...

Combustion Chamber
A combustion chamber is part of an internal combustion engine in which the fuel/air mix is burned. For steam engines, the term has also been used for an extension of the 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 (gasoline) engines, the combustion chamber is usually located in the cylinder head. The engines are often designed such that the bottom of combustion chamber is roughly in li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cylinder Head
In an internal combustion engine, the cylinder head (often abbreviated to simply "head") sits above the cylinders and forms the roof of the combustion chamber. In sidevalve engines, the head is a simple sheet of metal; whereas in more modern overhead valve and overhead camshaft engines, the cylinder head is a more complicated block often containing inlet and exhaust passages, coolant passages, valves, camshafts, spark plugs and fuel injectors. Most straight engines have a single cylinder head shared by all of the cylinders and most V engines have two cylinder heads (one per bank of cylinders). Design A summary of engine designs is shown below, in chronological order for automobile usage. Sidevalve engines In a flathead (''sidevalve'') engine, all of the valvetrain components are contained within the block, therefore the head is usually a simple sheet of metal bolted to the top of the engine block. Sidevalve engines were once universal in automobiles but are now lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crankshaft
A crankshaft is a mechanical component used in a piston engine to convert the reciprocating motion into rotational motion. The crankshaft is a rotating 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 or machining process. Design The crankshaft located within the engine block, 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 enormous stresses, in some cases more than per cylinder. Crankshafts for single-cylin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercedes-Benz W124
The Mercedes-Benz W124 is a range of mid-size cars made by Daimler-Benz from 1984 to 1997.

Mercedes-Benz M130 Engine
The Mercedes Benz M180 Engine was a single overhead camshaft inline-6 cylinder engine introduced at the Frankfurt Motor Show in April 1951 to power the company's new 220 (W187). It was the first engine with a cylinder bore greater than its stroke that Mercedes had installed in a production car, while using a reverse-flow cylinder head . It spawned four variants through 1968, the final and largest being the 2.8 L M130. It was achieved by boring out and stroking the M180's original "over-square" bore × stroke of to , yielding a displacement of . Mercedes also unveiled at the 1951 Frankfurt Motor show a larger 3.0-litre M186 ‘big six’ inline-6 to power its new flagship 300 (W186) ''Adenauer'' four-door saloon. While sharing many design features such as staggered valve arrangement and rockers running off a single overhead camshaft driven by a duplex cam-chain, the engines were of completely different design with little or no inter-changeability of parts.''Six Appeal'', Mer ...
