← ScienceWhich consequence results when catalytic converter honeycomb bonds degrade?
A)Increased regulated exhaust emissions✓
B)Decreased engine flywheel acceleration
C)Elevated fuel injector pulse width
D)Reduced oxygen sensor responsiveness
💡 Explanation
Decomposition of wall material means less surface area for catalysis because surface catalyzed reactions depend upon *adsorption*. Therefore, regulated exhaust emissions increase, rather than alternative sensor or fuel behavior modifications which don't directly reduce emissions under these conditions.
