AIR INTAKE MANIFOLD FOR INTERNAL COMBUSTION ENGINE

摘要

Air intake manifold for an internal combustion engine comprising a manifold body (1) enclosing a plenum (3) comprising an intake orifice and from which open out through a respective distribution orifice (4) a series of lateral intake conduits (5) and where the manifold body integrates a device for re-injecting blowby gases and canister gases into the plenum (3), characterized in that the manifold body (1) comprises a cover (2) extending the length of the plenum (3), next to the intake conduits (5), so as to define a part of the periphery thereof in this area, and pierced by a series of holes corresponding to the respective distribution orifices (4), where this cover (2) comprises at least one coupling stub (6) equipped with branch fittings for reinjection (7, 8) respectively branched onto the circuit for recirculating blowby gases and canister gases and thereby constituting the device for reinjection of these gases into the plenum (3).
