What are the impacts of a damaged catalytic converter?

[IrisDella]

Here are the impacts caused by a damaged catalytic converter: 1. Excessive exhaust emissions: When the catalytic converter is clogged or fails, harmful gases such as CO, HC, and NOx are directly emitted, resulting in non-compliant exhaust emissions. 2. Increased fuel consumption: A clogged catalytic converter affects the normal operation of the oxygen sensor, which in turn affects the accuracy of the oxygen sensor signals received by the engine. This leads to inaccurate control of fuel injection, air intake, and ignition, naturally increasing fuel consumption. 3. Poor exhaust flow and reduced power: This is more noticeable in turbocharged models. When the catalytic converter is clogged, high-pressure exhaust flow is hindered, affecting air intake and causing a decrease in engine power. This results in reduced acceleration and a feeling of sluggishness while driving.
