How many days does a newly replaced catalytic converter need to run?

[Grady]

The catalytic converter needs to reach a certain temperature before it can function fully and normally. The time required varies depending on the vehicle and external temperature conditions. It could take a few minutes or over ten minutes—there's no standard timeframe. Definition of a catalytic converter: A catalytic converter is the most important external purification device installed in a vehicle's exhaust system. It converts harmful gases such as CO, HC, and NOx emitted from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. Cleaning a catalytic converter: The cleaning method for a catalytic converter involves using an intravenous drip. This method connects a plastic hose to the engine's vacuum solenoid valve and relies on air pressure in the hollow tube to draw cleaning fluid from an infusion bottle into the engine. As the cleaning fluid exits through the exhaust pipe, it cleans the catalytic converter. Lifespan of a catalytic converter: The typical lifespan of a catalytic converter ranges between 80,000 to 100,000 kilometers. The exact lifespan depends on the vehicle's usage conditions, as well as the quality of fuel used and the driving environment.
