Intake system of internal combustion engine

摘要

The present invention relates to an Intake system (10) of an internal combustion engine in particular of a motor vehicle. The intake system (10) comprises an intake manifold (12) with at least two feed pipes (14) which are connected with intake ports of a cylinder head of the internal combustion engine. Further the intake system (10) comprises at least one intermediate chamber (30), which has connections (34) to an interior volume (24) of each feed pipe (14). Each connection (34) can be opened or closed by way of at least one intake control valve (49). The at least one intake control valve (49) comprises a switch chamber (48) which has a connection (60, 62) to means for creating a pressure in the switch chamber (48). The switch chamber (48) is separated from the interior volumes (24) of the feed pipes (14) and from the intermediate chamber (30) by way of at least one diaphragm (50). The connections (34) between the interior volumes (24) of the feed pipes (14) and the intermediate chamber (30) can be opened or closed by the at least one diaphragm (50).
