Which outcome results when a catalytic converter substrate plugs?

A)Increased upstream exhaust backpressure occurs
B)Fuel-air mixture leans excessively
C)Oxidation catalyst function improves
D)Engine compression ratio steadily decreases

💡 Explanation

Increased upstream backpressure occurs because restriction reduces flow into the converter which relies on *mass transport limitation*, therefore forcing build-up, rather than reducing conversion efficiency or affecting engine parameters.
