Catalytic converters are critical components of modern vehicles’ exhaust systems, as they help to reduce harmful emissions produced by the engine. These emissions include gases such as carbon monoxide, hydrocarbons, and nitrogen oxides, which contribute to air pollution and global warming. When the harmful gases pass through the catalytic converter, these metals help to break down the gases into less harmful substances, reducing the amount of pollution released into the atmosphere. This process helps to lower the negative impact of vehicles on the environment and improves overall air quality.
