[McNora]

A damaged catalytic converter can indeed lead to increased fuel consumption. Here are the specific details about the catalytic converter: 1. Function: The catalytic converter is an emission control device in the engine. Its proper operation directly affects the engine's fuel consumption, power output, and emission levels. 2. Symptoms of failure: If it becomes clogged or malfunctions, it will cause excessive exhaust emissions and impair engine performance. Common symptoms include increased fuel consumption, poor acceleration, unusual noises from the exhaust pipe, and foul-smelling exhaust. 3. Maintenance interval: Generally, the catalytic converter should be cleaned every 30,000 kilometers. It's also advisable to clean it before annual vehicle inspections to ensure passing the emissions test smoothly.
