V6 Grafton Street
A V6 engine is a six-cylinder piston engine where the cylinders share a common crankshaft and are arranged in a V configuration. The first V6 engines were designed and produced independently by Marmon Motor Car Company, Deutz Gasmotoren Fabrik and Delahaye. Engines built after World War II include the Lancia V6 engine in 1950 for the Lancia Aurelia, and the Buick V6 engine in 1962 for the Buick Special. The V6 layout has become the most common layout for six-cylinder automotive engines. Design Due to their short length, V6 engines are often used as the larger engine option for vehicles which are otherwise produced with inline-four engines, especially in transverse engine vehicles. A downside for luxury cars is that V6 engines produce more vibrations than straight-six engines. Some sports cars use flat-six engines instead of V6 engines, due to their lower centre of gravity (which improves the handling). The displacement of modern V6 engines is typically between , though l ...

IC Engine
An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons (piston engine), turbine blades (gas turbine), a rotor (Wankel engine), or a nozzle (jet engine). This force moves the component over a distance, transforming chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to. This replaced the external combustion engine for applications where the weight or size of an engine was more important. The first commercially successful internal combustion engine was created by Étienne Lenoir around 1860, and the first modern internal combustion engine, known as th ...

Centre Of Gravity
In physics, the center of mass of a distribution of mass in space (sometimes referred to as the balance point) is the unique point where the weighted relative position of the distributed mass sums to zero. This is the point to which a force may be applied to cause a linear acceleration without an angular acceleration. Calculations in mechanics are often simplified when formulated with respect to the center of mass. It is a hypothetical point where the entire mass of an object may be assumed to be concentrated to visualise its motion. In other words, the center of mass is the particle equivalent of a given object for application of Newton's laws of motion. In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the physical body, as is sometimes the case for hollow or open-shaped objects, such as a horseshoe. In the case of a distri ...

Lancia V4 Engine
Italian automobile company Lancia was the first to manufacture cars with V4 and V6 engines in series-production. This started with a number of V4-engine families, that were produced from the 1920s through 1970s. The Lancia V4 pioneered the narrow-angle V engine design, more recently seen in Volkswagen's VR5 and VR6 engines. By using very shallow V-angles — between 10° and 20° — both rows of cylinders could be housed in an engine block with a single cylinder head, like a straight engine. A determining characteristic was the use of overhead camshafts (either single or double), in which a camshaft would serve the same function for all cylinders — in ''both'' cylinder banks. Lambda The first V4 was used in the Lambda from 1922 through 1931. It was a 20° narrow-angle aluminium design. All three engine displacements shared the same long stroke, and all were SOHC designs with a single camshaft serving both banks of cylinders. Engines: * , at 3250 rpm * , at 3250&n ...

Balance Shaft
Balance shafts are used in piston engines to reduce vibration by cancelling out unbalanced dynamic forces. The counter balance shafts have eccentric weights and rotate in opposite direction to each other, which generates a net vertical force. The balance shaft was invented and patented by British engineer Frederick W. Lanchester in 1907. It is most commonly used in inline-four and V6 engines used in automobiles and motorcycles. Overview The operating principle of a balance shaft system is that two shafts carrying identical eccentric weights rotate in opposite directions at twice the engine speed. The phasing of the shafts is such that the centrifugal forces produced by the weights cancel the vertical second-order forces (at twice the engine RPM) produced by the engine. The horizontal forces produced by the balance shafts are equal and opposite, and so cancel each other. The balance shafts do not reduce the vibrations experienced by the crankshaft. Applications Two-cylinder ...

Harmonic 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 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, or ...

Inline-three Engine
A straight-three engine (also called an inline-triple or inline-three) is a three-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. Less common than straight-four engines, straight-three engines have nonetheless been used in various motorcycles, cars and agricultural machinery. Design A crankshaft angle of 120 degrees is typically used by straight-three engines, since this results in an evenly spaced firing interval. Another benefit of this configuration is perfect primary balance and secondary balance, however an end-to-end rocking couple is induced because there is no symmetry in the piston velocities about the middle piston. A balance shaft is sometimes used to reduce the vibrations caused by the rocking couple. Other crankshaft angles have been used occasionally. The 1976-1981 Laverda Jota motorcycle used a 180 degree crankshaft, where the outer pistons rise and fall together and inner cylinder is offset from them by 180 degrees. Th ...

Chevrolet C/K
C/K is a series of trucks that was manufactured by General Motors from the 1960 to 2002 model years. Marketed by both the Chevrolet and GMC divisions, the C/K series encompassed a wide range of vehicles. While most commonly associated with pickup trucks, the model line also included chassis-cab trucks and medium-duty trucks and served as the basis for GM full-size SUVs. Through its entire production, the model line competed directly against the Ford F-Series and the Dodge D series (later the Dodge Ram pickup). Used for both the model branding and the internal model code, "C" denoted two-wheel drive; "K" denoted four-wheel drive. Four generations of the model line were produced, including the second-generation "Action Line" and third-generation "Rounded Line" vehicles. For the fourth generation, GMC revised its branding, changing to a singular GMC Sierra nameplate (C/K remained as an internal model code). For South America, the model line was manufactured by General Motors ...

GMC V6 Engine
GMC Truck produced a unique 60 degree V6 engine family from 1959 through 1974, in gasoline and diesel versions. V8 and V12 derivatives of the basic design were also produced. Examples of this engine family were found in pickup trucks, Suburbans, heavier trucks and motor coaches. V6 big block engines were produced in 305, 351, 401 and 478 cubic-inch (5.0, 5.8, 6.6, and 7.8 respectively liter) displacements, with considerable parts commonality. During the latter years of production, versions with enlarged crankshaft journals were manufactured as well. GMC produced a 60° V8 with a single cam shaft using the same general layout (bore and stroke) as the 478 V6. The 637 V8 was the largest displacement production gasoline V8 ever made for highway trucks. The largest engine derived from the series was a "Twin Six" V12, which had a unique block and crankshaft, but shared many exterior parts with the 351. Diesel versions of the 351, 478 and 637, advertised as the ToroFlow, we ...

Mitsubishi Lancer
The Mitsubishi Lancer is an automobile produced by the Japanese manufacturer Mitsubishi Motors since 1973. The Lancer has been marketed as the Colt Lancer, Dodge Colt, Plymouth Colt, Chrysler Valiant Lancer, Chrysler Lancer, Eagle Summit, Hindustan Lancer, Soueast Lioncel, and Mitsubishi Mirage in various countries at different times, and has been sold as the Mitsubishi Galant Fortis in Japan since 2007. It has also been sold as Mitsubishi Lancer Fortis in Taiwan with a different facelift than the Galant Fortis. In Japan, it was sold at a specific retail chain called Car Plaza. Between its introduction in 1973 and 2008, over six million units were sold. There have been nine generations of Lancers before the current model. Mitsubishi ended production of the Lancer in August 2017 worldwide, with the exception of Taiwan and China. An extensive facelift was given to the car by Pininfarina's Chinese offices. First generation (A70; 1973) The first Lancer (A70) was launched ...

Mitsubishi Mirage
The Mitsubishi Mirage is a range of cars produced by the Japanese manufacturer Mitsubishi from 1978 until 2003 and again since 2012. The hatchback models produced between 1978 and 2003 were classified as subcompact cars, while the sedan and station wagon models, marketed prominently as the Mitsubishi Lancer, were the compact offerings. The liftback introduced in 1988 complemented the sedan as an additional compact offering, and the coupé of 1991 fitted in with the subcompact range. The current Mirage model is a subcompact hatchback and sedan and it replaces the Mitsubishi Colt sold between 2002 and 2012. Nameplate history The Mirage has a complicated marketing history, with a varied and much convoluted naming convention that differed substantially depending on the market. Mitsubishi used the Mirage name for all five generations in Japan, with all but the first series badged as such in the United States. However, other markets often utilized the name Mitsubishi Colt and sedan var ...
