Abstract: A fuel vapor storage and recovery apparatus includes a fuel vapor storage canister, said fuel vapor storage canister comprising at least first and second vapor storage compartments filled with an absorbent material, for instance filled with activated carbon, at least a vapor inlet port, an atmospheric vent port and a purge port. Said fuel vapor storage canister defines an air flow path between said vapor inlet port and said atmospheric vent port during shut-off of the internal combustion engine of the vehicle. During purging cycles there is defined an air flow path between said atmospheric vent port and said purge port wherein said first and second vapor storage compartments are arranged in concentric relationship and wherein said first and second vapor storage compartments in flow direction are separated from each other by an air gap diffusion barrier.

Abstract: The invention relates to an intake manifold (1) for a primary air system of an internal combustion engine, especially in a motor vehicle. The inventive intake manifold (1) comprises a pipe section (2) that is composed of at least two pipe parts (3, 4) which are produced as injection-molded parts and are joined to each other by means of a connection (12). Said connection (12) is formed by a material that is sprayed on or injected in the area of a dividing line (5) between the pipe parts (3, 4).
