Catalytic Converter for 2 Cycle EMD Diesel Engine

A utility company was interested in retrofitting their emergency diesel generators for compliance with the 2013 RICE NESHAP rule set by the United States EPA. These are the Reciprocating Internal Combustion Engine National Emission Standards for Hazardous Air Pollutants.


The engine for retrofit was a 3150 kW EMD20-645, 2-cycle diesel.


DCL designed a QUICK-LID® oxidation catalytic converter to meet an emission target of 70% CO destruction. The catalytic converter achieved 86% CO destruction, exceeding the RICE NESHAP standard. The new catalytic silencer fit onto exhaust system upstream of the existing silencer. A Continuous Parameter Monitoring System (CPMS) was included in the project.
