What it is:

Cat Oxidation Catalysts help lower engine emissions through chemical reactions that convert carbon monoxide, hydrocarbons and aldehydes into carbon dioxide and water.

How it works:

A catalyst assembly–available to suit many machine applications– is installed in place of the standard muffler. Exhaust flows through a steel housing with a specially formulated catalyst. Here, chemical reactions work to minimize machine emissions.

What it does:

> Carbon monoxide reduction up to 85 percent in engines up to 750 horsepower

> Hydrocarbon reduction up to 60 percent

> Particulate matter reduction up to 20 percent

> Caterpillar Standard Parts Warranty applies
