摘要：
Two commercial catalysts (PtRh and PdRh) were treated in N-2+H2O (or Air+H2O) at 900, 1000 or 1100 degrees C (Lab. ageing) or aged on an engine bench for 25, 50 or 200h. OSC (transient CO oxidation) and catalytic activity for CO, HC and NO abatment (light-off temperatures and conversion at 450 degrees C) were measured over these aged catalysts. Correlations between OSC values and catalytic activity are discussed for a possible On-Board Diagnostic application.
