V12 engine

The twelve-cylinder is a type of piston engine.



It is usually performed as a V- engine, seldom as a boxer engine ( only for racing purposes ) and even more rarely than in-line engine ( just as a ship's engine ). It can be both petrol and designed as a diesel engine. These motors are almost always water- cooled in - car construction, in rare cases of trucks used to be air-cooled.


Twelve cylinder engines are installed in cars of the upper class as well as in sports cars and supercars. In addition, it is also available as rail traction ( diesel locomotives and diesel railcars rare ), small and large vessels (as V - series engine or motor). They are also the most commonly built tank engines and are also used as a stationary power plant engines or wheel emergency generator.

Previously, V12 engines commonly found as aircraft engines, especially during the Second World War in all the belligerent powers, and a few years later also in passenger and cargo aircraft.


Twelve-cylinder V- engines have especially as gasoline engines an excellent smoothness, because in them the free inertial forces are stronger than the eight-cylinder V- engine, or even the series balanced.

Because of the many cylinders they have a very uniform engine noise. The latter can, however, as well as smooth, especially in a series of sports car engines of Italian design ( 180 ° V engine in some Ferrari models) vary slightly due to the other crankshaft crank and firing order, and in this particular case, slightly less cultivated. The only advantage of this design is the ability to drive at very high speeds.
