ABSTRACT:
A device for centrifugal purification of combustion air in an internal combustion engine, especially for a motor saw, wherein the engine has an air cooling system including a fan wheel (19) provided in a helical fan housing (18). The device includes an air nozzle which defines an air passage for conducting combustion air from the fan housing to the engine. The air nozzle (10) is located adjacent to the fan wheel. The nozzle has an inlet (12) including a baffle wall (14) located close to the periphery of the fan wheel and conducting air to the inlet. The baffle wall has a part-elliptical shape as seen in the direction of air flow.
