This $2,000 Hack Can Reduce Diesel Truck Pollution by up to 90%
What is a diesel oxidation catalyst?
Diesel oxidation catalysts (DOCs) are a type of low-maintenance catalytic converter built for diesel engines. They drastically reduce the Carbon Monoxide, Hydrocarbons, and Particulate emissions put out by diesel vehicles. These inexpensive parts can be retrofitted to any diesel vehicle to reduce pollution.
DOCs work by exposing exhaust gases created by the engine to a catalyst. In this case the catalyst is built into a honeycomb structure which provides maximum surface contact with exhaust gases. This catalyst transforms the components of these gasses into water and carbon dioxide.
In short, it turns pollutants into harmless substances. Interested owners can easily find compatible parts online. Many shops that specialize in work trucks will likely be familiar with installation. Expensive installation isn’t necessary for those with a knack for DIY repair.
