Abstract
An intake pipe system for an opposed-piston or V-engine consists of a U-shaped collector intake pipe at whose two U-legs individual intake pipes are mounted to the two banks of cylinders. In the center between the U-legs, an intake stub is mounted that points in the same direction. In order to achieve an optimal charging effect, the total length of the collector intake pipe amounts to twice the total length of the individual intake pipe that is designed as a curve with respect to space.
