Abstract: Sorbent material sheets products that include sorbent material sheets and at least one porous cover layer are attached to an inner wall surface that is defined by an air intake. The sorbent material sheets collect vapors such as hydrocarbon vapors from engine components such as the combustion chamber, injectors, carburetor, fuel ports, crankcase, or other engine components, thereby reducing evaporative emissions. In certain configurations, the sorbent material sheet product includes an edge seal that improves the handling of the sorbent material sheets during the manufacturing process.
