ABSTRACT:
An intake venting system comprising a plurality of intake passages. Each of the intake passages leads to a respective cylinder in an engine. A reed valve is disposed in and attached to each intake passage. Each of the reed valves allows fluid flow toward the respective cylinder and obstructs fluid back-flow in the reverse direction. An intake valve is seated in each of the intake passages between the reed valve therein and the cylinder to which the respective intake passage leads. A bypass port is located on each intake passage so that each bypass port communicates with a trapped volume defined by the portion of the intake passage between the reed valve and intake valve therein. A control valve is connected to each of the bypass ports, with the control valve enabling communication between a predetermined pair of the trapped volumes during a portion of the engine cycle when the pressure in one of the pair of trapped volumes exceeds the pressure immediately upstream thereof, and the pressure in the other of the pair of trapped volumes is less than the pressure in the one of the pair of trapped volumes.
