ABSTRACT:
A method and apparatus for removing entrained matter from the intake air of a chain saw internal combustion engine of the type including at least one piston and cylinder, a crank shaft, and a carburetor.
The apparatus includes a shroud surrounding at least one end of the crank shaft with an air inlet fashioned into the shroud at a position adjacent to said one end of the crank shaft and an air outlet fashioned into the shroud at a position remote from the air inlet. An air passage opens into the shroud adjacent the crank shaft for providing fluid communication between the interior of the shroud and the carburetor. The crank shaft is provided with a hub having on opposite faces thereof a first and second cascade of radial flow compressor blades to centrifugally impel air and entrained particulate matter away from the crankshaft. The compressor blades serve to remove at least a portion of the entrained matter from the combustion inlet air prior to the air entering the air passage for delivery to the carburetor.
A further apparatus aspect of the invention includes an accumulation chamber positioned within the air passage which provides a flow reversal of the combustion air. A filter diaphragm is positioned across the accumulation chamber to further removed very fine particulate matter from the intake air prior to delivery to the carburetor.
