Air induction channel system for internal combustion engine

摘要

The channel system has a central collection inlet channel from which separate induction channels formed from two part pieces extend out spirally. The inner walls of the induction channels and the walls of the collection inlet channel are formed from adaptors fitted in the part pieces from the sealing surface side. At least one of the adaptors is in the form of a non-through-flow container (15), which is connected by a channel sector (16) coming out in it to the collection inlet channel. The container is airtight.
