System for sucking in air for an internal combustion engine includes single air intake channels leading to each internal combustion cylinder and a combustion gas return channel feeding into each air intake channel

摘要

Near an inlet for a combustion gas return channel (13) into each single air intake channel (16) there is a valve (15) for closing and opening a connection between combustion gas return and air intake channels. This valve is an automatic valve that closes the connection by using a pre-defined spring force or opens it by using low pressure in the intake phase of an internal combustion engine, in order to let combustion gas flow into the air intake channel.
