Abstract

In a suction pipe installation for multicylinder internal combustion engine with a collector suction pipe, a suction distributor is connected therewith. Adjacently disposed individual suction pipes form a unitary unit with the collector suction pipe. The individual suction pipes extend from the flanges a curve of more than 90.degree. to connecting flanges. The collector suction pipe 1 is mounted in the chamber enclosed by the individual suction pipes, so that it does not require any additional space. A quiet airflow is formed in the straight line segment of the collection suction pipe 1, and in which an air amount meter 18 for a fuel injection installation is installed.
