Air induction systems for internal combustion engines

An air induction system for an internal combustion engine, the air induction system comprising:

• an air intake plenum that conducts intake airflow to an air cleaner for cleaning prior to combustion in the internal combustion engine, the air intake plenum movable with respect to the air cleaner between an open position separated from the air cleaner and a closed position connected to the air cleaner;
• a bellows that connects the air intake plenum to the air cleaner when the air intake plenum is in the closed position, the bellows being axially elongated and having an interior channel extending between a first opening at an upstream first end thereof and a second opening at a downstream second end thereof that seals with the air cleaner, the bellows forced into a compressed state when the air intake plenum is in the closed position and biased into an extended state when the air intake plenum is in the open position;
• and
• a shield that blocks inflow of rain water to the bellows when the air intake plenum is in the open position and the closed position, the shield comprising
• an axial support member that axially extends along the interior channel;
• and
• a radial cover plate that radially extends from the axial support member, the radial cover plate having a radially outer edge that is located adjacent an inner perimeteral surface of the bellows when the air intake plenum is in the open position, the radially outer edge sealing with the bellows when the air intake plenum is in the open position and axially spaced apart from the upstream first end of the bellows when the air intake plenum is in the closed position so as to define a first perimeteral gap through which intake airflow passes to the air cleaner.
