ABSTRACT:
An internal combustion engine intake manifold has a wall separating internal manifold space from an external space. A purge valve for purging fuel vapors from an evaporative emission space of a fuel storage system for the engine mounts on the wall external to the internal manifold space and places a purge outlet port of the purge valve in communication with the internal manifold space. An EGR valve for recirculating engine exhaust gases mounts on the wall such that an EGR outlet port of the EGR valve is communicated to the internal manifold space.
