Catalyst Module
Cummins®

The Catalyst Module, also known as a catalytic converter, is an emissions control device installed in the exhaust system of a truck. Its purpose is to reduce harmful pollutants such as carbon monoxide, nitrogen oxides, and hydrocarbons from the exhaust gases produced by the engine. The Catalyst Module works by using a catalyst to convert these harmful gases into less harmful ones before they are released into the environment. It consists of a metal housing that contains a ceramic honeycomb structure coated with precious metals such as platinum and palladium. The honeycomb structure provides an enormous surface area where chemical reactions can take place effectively. As exhaust gases pass through it, they react with the catalysts, which cause them to break down into less harmful components. The Catalyst Module plays a critical role in reducing air pollution and meeting emission standards set by regulatory agencies around the world.
