Method for avoid accumulation and clogging in filters of internal combustion engine has filtrating elements with inlet surface placed so that kept particles fall down at outer periphery of elements

摘要

Method involves contact between gas and filtration system. Filtration system comprises supply of gas to filter (1), filtration housing (2), filtrating elements (3), and gas outlet (6). Filtrating elements have hollow part (4) delimited by filtrating wall (5) and placed inside filtration housing. Inlet surface of filtrating elements are placed so that kept particles fall down, due to gravity, at outer periphery of elements. An Independent claim is also included for the filtration system.
