Cat Clean Emissions Module (CEM)

The Tier 4 Final engine has been optimized to work with the Cat CEM.
The CEM is a reliable, compact, and lightweight system that gives maximum installation flexibility.
It features a diesel oxidation catalyst for particulate matter (PM) and hydrocarbon (HC) control.
Selective catalytic reduction (SCR) reduces NOx output and provides integrated sound attenuation.
The CEM is controlled by a separate dosing module that has been integrated into the standard generator set controls for complete monitoring, protection and closed loop NOx control.
For more information on the CEM, refer to cut sheet LEHE0359.
