Case No. 503: Johnson Matthey DOC Controls PM from Emergency Standby Caterpillar 3412 Diesel Engine

0

Diesel Oxidation Catalyst (DOC) has proven to be effective in achieving low to moderate reductions in particulate matter emissions, while simultaneously reducing CO and HC. To meet SCAQMD Rule 1470 for emergency backup diesel engines, Cal State Fullerton had to reduce PM emissions by 20%. Johnson Matthey’s Diesel Catalytic Converter (DCC™), a high performance DOC was chosen.

 

Background

South Coast AQMD Rule 1470 requires owners of new and existing emergency backup diesel engines greater than 50 Hp to control particulate emissions. Rule 1470 was developed in response to the California Air Resources Board’s Airborne Toxics Control Measure (ATCM). Quinn Power Systems, a Caterpillar engine distributor was contacted by Cal State Fullerton for help. Quinn Power in turn contacted JM.
