  • Apparatus for cleaning diesel engine exhaust gas
    Patent number: 5016437
    Abstract: Diesel engine exhaust gas is cleaned by burning soot to convert the soot into gas. For this purpose the exhaust gas from the diesel engine is caused to travel through a helical or spiral channel, whereby centrifugal force causes soot particles to collect on radially outer, inner circumferential channel surfaces, where the collected soot is combusted by heating elements reaching into these channels, preferably into channel pockets.
