How the Diesel Oxidation Catalyst Works
A precious-metal diesel oxidation catalyst is bonded to a monolithic, flow-through catalyst core. As exhaust passes through the core, the catalyst oxidizes the soluble organic fraction (SOF) of diesel particulate matter and other gaseous components. The core is made of either corrugated, high-temperature-resistant stainless steel foil or thin-wall cellular ceramics, and is packaged into a rugged stainless steel container.
Conversion of the soluble organic fraction may exceed 80%, and total diesel particulate matter (DPM) conversions between 20% and 50% are typically observed. Heavy-duty catalysts incorporate sulfate suppressants to maximize particulate-matter performance. Low-sulfur fuel is recommended for high DPM conversions.
