AIR CLEANER FOR INTERNAL COMBUSTION ENGINE Russian patent published in 1997 - IPC

FIELD: manufacture of engines. SUBSTANCE: dust-and-air flow enters ionizer 11 through perforated housing 12. Particles of dust comparable with sizes of perforations and lesser than these perforations enter ionizer together with air flow where they are charged due to contact with disks 21. Then ionized flow enters electric cyclone 13. Particles of dust move around electrode 16 and settle on inner surface of housing wherefrom they enter dust collectors 22 and 23. Dust-and-air flow moves around filter element 7 through outlet branch pipe 25 and inlet branch pipe 5 fitted tangentially relative to housing 1. Under action of centrifugal force and forces of electric field, charged particles repel filter element 7 and settle on inner surface of housing 1 wherefrom one part of dust is removed and other part returns to ionized flow of air. EFFECT: enhanced efficiency. 2 dwg
