ABSTRACT:
An air cleaner element for an internal combustion engine capable of adsorbing fuel vapor and having an air cleaning filter medium and a fuel vapor adsorption filter medium containing activated carbon fibers, the filter media being partly bonded together with an adhesive into a unitary construction. Both the filter media have a large surface area so that the reduction in size of the air cleaning filter medium and the increase in size of an air cleaner case may not be needed. Furthermore the wear and abrasion of activated carbon fibers due to the vibrations may be avoided.
