Abstract
The intake system is connected to a cylinder head of the internal-combustion engine that, for each cylinder, has two intake ducts. The intake ducts are located on a joint plane extending vertically with respect to the cylinder bore axis. A curve-shaped pipe body piece of the intake system leads away from the cylinder in which the ducts are continued and have an interlaced course with respect to one another. This course is developed in such a way that, in a horizontal plane extending away from the cylinder head, the ducts are located next to one another--seen in transverse direction of the internal-combustion engine.
