The emission control system employed with the Isuzu

4LE2X diesel engine consist of a Diesel Oxidation Catalyst

(DOC).

This device oxidizes large amounts of harmful nitrogen

oxides (NOx) and particulate matter (PM) which are emitted

by diesel engines. These exhaust emissions pose serious

environmental and health risks. No maintenance or service

is required for the DOC device used on this generator.

The DOC does not ﬁlter particles it oxidizes them. This

catalyst (honeycomb like structure) uses a chemical

process to break down pollutants in the exhaust stream

into less harmful components. In general this catalyst

collects/burns accumulated particulates. The DOC contains

palladium and platinum which serve as a catalysts to oxidize

hydrocarbons and carbon monoxide.
