Noise reduction is a major concern in the recent times and global automotive industries evolve new technology to meet the norms. The major contribution to vehicle’s interior noise is from engine, intake, exhaust, structure, aerodynamic and road. In recent days, more attention is given to other sources of noises which are dominant. Purge noise is one such noise which has more impact to the interior noise because the cabin has become much quieter due to the latest advancements and new technologies used in vehicle design and development. Using the air dampening device in the vapor line is one of the techniques to minimize the purge noise. In this paper a study is carried out in order to optimize the design of air dampening device which meets the requirements. Fuel vapors that got collected in canister will purge through vapor line and are controlled by purge valve before they enter the engine.
