Car catalytic converters and parts are essential components of a vehicle's exhaust system that help reduce harmful emissions. These devices work by converting toxic pollutants from the engine's exhaust into less harmful substances before they are released into the environment. Catalytic converters are typically made of ceramic or metal and have a honeycomb-like structure that provides a large surface area for chemical reactions to take place. In addition to catalytic converters, other parts of the exhaust system include oxygen sensors, exhaust pipes, and mufflers. It is important to ensure that these components are functioning properly to maintain optimal performance and reduce pollution.
