Abstract

1508944 Exhaust gas filtration ROBERT BOSCH GmbH 24 June 1976 [26 June 1975] 26305/76 Headings BIT and B1W In a method of filtering soot particles from the exhaust gases of a self-igniting, i.e. diesel, internal combustion engine using a filter inserted in the exhaust gas pipe at a position directly adjacent the outlet for exhaust gases from the combustion chambers, some of the exhaust gas is fed back to the inlet to the engine to increase the temperature of exhaust gases leaving the engine and, hence, assist self-cleaning of the filter by burning of the separated soot particles from the filter. The filter may comprise a metal fabric, e.g. steel wool.
