Development of a Hydrocarbon Adsorption Filter

On the LEV II EVAP regulations, it will become significantly important for an Air Intake System to reduce Diurnal Breathing Loss. Therefore, the authors have developed an air cleaner, which has a function to adsorb evaporative emissions using an activated carbon filter. It contributes to satisfy the LEV II and PZEV regulations for useful life span 15years. The characteristics of this filter are high adsorption performance and low flow restriction.
