← TechnologyWhich outcome occurs when liquid fuel floods a catalytic converter?
A)Rapid catalyst material degradation✓
B)Increased engine compression ratio
C)Decreased hydrocarbon emissions
D)Enhanced oxygen storage capacity
💡 Explanation
Rapid catalyst material degradation occurs because thermal runaway through exothermic oxidation of the fuel leads to overheating and structural damage in the converter via the washcoat delamination mechanism; therefore the substrate melts, rather than lowering emissions since complete combustion ceases.
