Abstract
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 includes an air conductor surrounding a fan wheel arranged to propel intake air around an axis of the fan wheel. An inner wall of the air conductor is arranged for guiding air propelled by the fan wheel. An air nozzle for cleaning of intake air is arranged on the inner wall of the air conductor radially close to said fan wheel. The air nozzle serves as a passage way for providing cleaned intake air from the fan wheel to the engine of the motor-driven tool, wherein the air nozzle and the air conductor are manufactured in one piece.
