Compact exhaust gas converter with pulse dampening means
Patent
·
OSTI ID:7348137
An internal combustion engine exhaust gas converter is described having opposing inlet and outlet means to channel the exhaust gas stream through a catalyst bed retained between perforated partitions. The improved construction and arrangement dampens pulsations in the gas stream and substantially eliminates damage to the catalyst. A hemispherical housing is connected to the gas inlet, and an internal, upstream, transverse perforated partition inside the housing has a large unobstructed upstream opening with an increasing diameter in the direction of the gas flow. The internal upstream perforated partition has an enlarging gas inlet plenum section leading to the catalyst bed, permitting gas flow outwardly onto a pulse absorbing space.
