Abstract

A suction pipe arrangement for reciprocating internal combustion engines with in-line cylinders, in which a common suction pipe with a fastening flange serving for fastening a throttle valve pipe connection is provided for the cylinders, and in which the tuned suction pipes which extend between the cylinder head of the engine and the common suction pipe are subdivided into two groups; the common suction pipe is thereby arranged in the longitudinal direction adjacent the cylinder row approximately at the height of the cylinder head while the first group of tuned suction pipes which branch off from the left portion of the common suction pipe, lead to the right connecting side of the cylinder head and the tuned suction pipes of the second group which branch off from the right portion of the common suction pipe, lead toward the left connecting side of the cylinder head, with each of the tuned suction pipes extending essentially S-shaped.
