1 Answers
Symptoms of a bad catalytic converter: decreased engine power performance, increased fuel consumption, increased exhaust channel resistance, deteriorated emissions, engine mixture concentration disorder, difficulty in ignition or incomplete combustion, engine overheating, lack of engine power, and unpleasant exhaust odor. The catalytic converter is an important external purification device installed in the automobile exhaust system, which converts harmful gases such as CO, HC, and NOx emitted by automobile exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction. When high-temperature automobile exhaust passes through the purification device, the purifying agent in the catalytic converter enhances the activity of the three gases CO, HC, and NOx, promoting certain oxidation-reduction chemical reactions.
