Adapter filter fixing type air cleaner and intake system including the same

An intake system, comprising:

• an air cleaner including:
• an air cleaner body having a hose housing and a duct housing that are coupled to form an internal space, wherein the hose housing includes a hose outlet from which clean air is discharged and the duct housing includes a duct inlet into which outside air is introduced;
• an air cleaner cover coupled to the hose housing to form the internal space;
• a cylindrical filter mounted in the internal space with an upward inclination arrangement in which a front side of the filter is raised approximately to the hose outlet and a rear side of the filter is lowered, and the filter is configured to change the outside air into the clean air by filtering foreign matters of the outside air;
• a filter fixer that generates a filter holding force to support the filter in the internal space;
• a filter adapter that generates a filter fixing force to fix the filter in the internal space;
• a housing strap installed on a coupling surface between the air cleaner body and the air cleaner cover to seal the internal space;
• a cover clamp configured to clamp the air cleaner body with the air cleaner cover;
• and
• a filter strap installed at a connection between the filter and the hose housing to seal the filter,
• wherein the filter fixer includes an adapter guide member formed at the rear side of the filter to guide an insertion path of the filter adapter, and a filter holding member formed at the front and rear sides and left and right sides of the filter to generate the filter holding force, wherein the filter adapter is fitted to the adapter guide member and generates the filter fixing force,
• wherein the filter fixer supports the filter through the filter holding force to maintain the upward inclination arrangement in the internal space, and the filter adapter generates the filter fixing force at the rear side of the filter, and
• wherein the adapter guide member is inclined to an inner wall of the air cleaner body and formed on the inner wall of the air cleaner body;
• an intake duct through which the outside air flows;
• an intake shield configured to filter foreign matters of the outside air flowing through the intake duct;
• and
• an intake hose through which the clean air flows from the intake shield to an engine.
