The six-cylinder is a type of reciprocating piston engines, particularly internal combustion engines.
Six-cylinder in-line engine are available as when V- motor and as a boxer engine. In the passenger car construction they come since the 1990s intensified as V-type engines are used because they have a more compact design compared to the R6 and B6 engines. A six- cylinder can be both petrol and designed as a diesel engine.
Six -cylinder engines are most commonly used in cars and truck engineering, in rare cases, also for motorcycles. But they also serve as a driving rail vehicles, light aircraft ( boxer engines American type ), small and large vessels (as inline engine ), as a power plant engine as well as for other applications.
Six -cylinder in-line and boxer engines have a special running, because in them any imbalances, ie the mass forces and moments of the first and second order are balanced.
Six-cylinder V-engines are partly reassured with balance shafts, or use six instead of three crank pins, ie the two otherwise working on a pin connecting rod of a piston V- pairing are hubversetzt, which may harm the stability of the crankshaft and additional manufacturing complexity. Occasionally there are also " Flat Six " said motors must be described more accurately as a 180 ° V- engines. However, they differ due to the co-rotating piston movements each 180 ° pairing in the smooth running of barely three cylinders.
Even away from internal combustion engines exist six-cylinder, including a reciprocating pumps or compressors.
