FLOW EFFECTS IN MONOLITHIC HONEYCOMB AUTOMOTIVE CATALYTIC CONVERTERS
This paper describes the results of durability tests of monolithic catalytic converters with mechanical devices used to tailor the exhaust gas flow. Deflectors of several different shapes show promise of extending the useful life of the converter by improving conversion efficiencies of hydrocarbons and CO. The tests were run on engine/dynamometers with round cross-sectional area samples and with symmetrical inlet cones. Improvements are found in initial activity and reduced deterioration. The penalty for altering the flow is in slower catalyst light-off and increased pressure drop.
