Modular intake manifold and integrated air intake system

摘要

An intake assembly includes an intake manifold comprising several interfitting sections attached to each other to define a plurality of air passages, and an EGR conduit within the intake manifold including openings in communication with each of the plurality of air passages. The EGR conduit is in communication with a source of exhaust gases and provides for the proximate and decentralized injection of exhaust gases into the intake manifold assembly. The intake manifold assembly also includes a passage that is in communication with a positive crankcase ventilation system (PCV) and a purge gas system. Gases from the PCV system and the gas purge system mix in the passage and then are communicated to the each of the air passages through individual opening passages.
