Preliminary investigation of light-duty diesel catalysts. Final report

Technical Report ·
OSTI ID:5474526
The laboratory testing of prototype Diesel catalytic converters on a production light-duty Diesel vehicle is described. Two manufacturers submitted catalysts which were retrofitted on the vehicle's exhaust system individually. Regulated and several unregulated emission rates were determined during the Federal Test Procedure (FTP) and the Highway Fuel Economy Test (HFET) for each system. Particulate rates and particulate collection for Ames bioassay was also determined. In addition to fresh Diesel catalysts, an aged Diesel catalyst was also evaluated. The emission rates of hydrocarbons (HC), carbon monoxide (CO), oxides of nitrogen (NOx), individual hydrocarbons, aldehydes, sulfates, and particulates are reported in grams per kilometer.
