Abstract
A sheet-like adsorption filter formed by sandwiching particulate activated carbon with heat-resistant nets and non-woven fabric sheets that have a percentage of void of 90% or higher, is disposed at an internal combustion engine side of a filter element.
Claims12
An air cleaner for an internal combustion engine, comprising:
- a housing that has an intake air inlet for introducing an external air and an intake air outlet for supplying an intake air to the internal combustion engine;
- an air cleaner element disposed within the housing for filtering the external air introduced;
- and
- adsorption means disposed at an internal combustion engine side of the air cleaner element for adsorbing a fuel vapor,
- wherein the adsorption means includes a particulate activated carbon, a heat-resistant mesh member for holding the particulate activated carbon, and a non-woven fabric, the non-woven fabric holds the particulate activated carbons from an upstream side and a downstream side of the intake air, and the heat-resistant mesh member covers at least one side of the non-woven fabric, wherein the one side is closer to the internal combustion engine.
An adsorption filter for use in an internal combustion engine air cleaner which has a housing that has an intake air inlet for introducing an external air and an intake air outlet for supplying an intake air to the internal combustion engine, and an air cleaner element disposed within the housing for filtering the external air introduced, and which is disposed at an internal combustion engine side of the air cleaner element, the adsorption filter comprising:
- a particulate activated carbon;
- a heat-resistant mesh member for holding the particulate activated carbon;
- and
- a non-woven fabric, wherein
- the non-woven fabric holds the particulate activated carbons from an upstream side and a downstream side of the intake air, and the heat-resistant mesh member covers at least one side of the non-woven fabric, wherein the one side is closer to the internal combustion engine.
