First Claim
1. In a motor vehicle having in an engine room a vapor diffusing device connected to a carbon canister for adsorbing vapors from a fuel tank, said device includinga front side channel member extending in said engine room from a front portion of the vehicle toward a passenger room of the same, said carbon canister having an evaporated gas tube connected to the fuel tank, a vacuum line connected to an intake manifold and a purge line connected to the intake manifold, and a first means extending from a purge air opening in the canister to the vapor diffusing device, the front side channel member functioning to vent fuel vapors in the canister to atmosphere, the improvement comprisinga structure including wall means mounted to a part of said channel member to define an enclosed chamber with said part;
- said first means fluidly connecting the interior of said enclosed chamber with the purge air opening of said carbon canister; and
second means defining a vapor diffusing opening through which the interior of said enclosed chamber is exposed to the interior of the engine room, said vapor diffusing opening being positioned sufficiently apart from the passenger room so as to prevent vapor from the engine room from reaching the passenger room.
