摘要： In an exhaust system for an internal combustion engine, wherein pollutants are removed from the exhaust gases by catalytic conversion, a pinwheel type of deflector positioned within the exhaust flow provides a radially-outwardly deflected swirl flow to the gases as they emanate from an exhaust pipe of one diameter into a canister of larger diameter for housing a catalytic converter. Such flow distribution results in improved catalytic conversion efficiencies obtainable by the converter and reduces its degradation rate inherent with time.
