What is a Catalytic Converter Cover and How Does it Work

A catalytic converter cover is a device that is designed to reduce the number of harmful emissions released into the atmosphere from an internal combustion engine. It works by converting pollutants such as carbon monoxide, hydrocarbons, and nitrogen oxides into less harmful substances before they are released into the air. Its complexity is the reason why catalytic converters are so valuable.

The cover acts as a barrier between the exhaust system and the environment, trapping pollutants in its honeycomb-like structure. Inside this structure are precious metals such as platinum (if you’re curious, check out our explainer on how much platinum is in a catalytic converter), palladium, and rhodium which act as catalysts to break down these pollutants into harmless gases like carbon dioxide and water vapor.

This process helps reduce air pollution levels significantly while also improving fuel efficiency.
