CANISTER FOR VEHICLES AND A FUEL EVAPORATION DEVICE HAVING THE SAME, CAPABLE OF PREVENTING AN OVERFLOW OF EVAPORATIVE GASES BY INCREASING THE PURGE EFFICIENCY OF THE CANISTER

摘要

PURPOSE: A canister for vehicles and a fuel evaporation device having the same is provided to reduce bleed emissions because evaporative emissions absorbed on active carbon near an air passage are desorbed by heating air supplied to the canister.;CONSTITUTION: A canister for vehicles comprises a supply passage for evaporative emissions, an air passage(36), a purge passage, and a heating module. The supply passage for evaporative emissions is connected to a fuel tank, and provided with the evaporative emissions. The air passage is selectively provided with the air from outside. The purge passage supplies the evaporative emissions to an engine according to a flow of the air. The heating module comprises a heating core(120) and a diffusion plate.(110). The heating core heats the air flowing in the canister. The diffusion is inserted between the air passage and the heating module. The diffusion plate heats the air evenly in the heating core by dispersing the air passed through the air passage.;COPYRIGHT KIPO 2012
