Claims

[Scope of utility model registration request]

In an intake air introduction device in which a clean side chamber in an air cleaner and an intake inlet in an intake manifold are connected by a bellows-shaped rubber intake conduit, the cross section of the connection part of the intake conduit to the air cleaner is defined by the minor axis in the vertical direction. It is characterized in that it is formed into an ellipse or an oblong shape with a longer diameter in the lateral direction, and a blow-by gas extraction pipe from the cylinder head or crankcase of an internal combustion engine is connected to the connecting portion of this oval or oblong cross section. Air intake system for internal combustion engines.
