<p>The invention deals with an arrangement for cleaning of intake air for an air-cooled internal combustion engine of a motor-driven tool, such as a chain saw. The arrangement comprises: an air conductor (10) surrounding a fan wheel (40) arranged to propel inlet air around an axis of the fan wheel, an inner wall (11) of the air conductor being arranged for guiding air propelled by the fan wheel; and an air nozzle (20) for cleaning of inlet air, arranged on the inner wall (11) of the air conductor (10) radially close to said fan wheel, the air nozzle (20) serving as a passage way for providing cleaned inlet air from the fan wheel to the engine of the motor-driven tool, wherein the air nozzle (20) and the air conductor (10) are manufactured in one piece. By manufacturing the air nozzle (20) and the air conductor (10) in one piece, a reliable cleaning of intake air is achieved, at the same time as the manufacturing and assembling process will be cost- effective and reliable.</p> |
