Diesel Exhaust After-Treatment & Maintenance (D.E.A.M.)



Diesel exhaust after-treatment technology, including wall-flow diesel particulate filters (DPF) and selective catalytic reduction (SCR) systems are at the forefront of clean diesel technology. The California Council on Diesel Education and Technology’s (CCDET) Diesel Exhaust After-treatment Maintenance training covers the following:

♦  Background on why diesel particulate filters are necessary;
♦  How the technology filters particulate matter (PM) and how regeneration strategies such as passive and active systems operate;
♦  Explores possible causes of filter failures as well as preventative maintenance practices to avoid break downs;
♦  An overview of SCR systems used on heavy-duty diesel engines.

In addition to these topics, the one day training also includes hands-on shop exercises designed to reinforce maintenance procedures employed to keep after-treatment technology and the engines they are installed on working at peak performance.
