Abstract
Abstract The specification relates to an intake manifold having an increased compaction. In this intake manifold, at least one fragile zone is formed parallel to its longitudinal axis in its wall. Crash impact is absorbed and the volume of the intake manifold decreases after crashing, because its cross section is crushed. The intake manifold of this invention has an increased compaction and can prevent the structure around fuel injection valves from breaking.
