| Abstract |
Gaseous, particulate, and sulfur-related emissions from six 49-state 1975 domestic production catalyst equipped vehicles (two Chevrolets, two Fords, and two Plymouths) and one 1975 imported prototype non-catalyst vehicle (Honda CVCC) were measured by a variety of chemical analysis techniques as a function of fuel sulfur level. Four separate and different sulfur level fuels were tested for each vehicle. The seven test vehicles were driven in accordance with the 1975 Federal Test Procedure (75 FTP) and the Highway Fuel Economy Test (HWFET) procedure. Sulfur dioxide, particulate matter, and sulfate emissions increased with increasing fuel sulfur and were greater during the HWFET cycle than during the 75 FTP cycle. The greatest particulate and sulfate emitters were the air pump equipped Ford vehicles, while the lowest particulate and sulfate emitter was the Honda CVCC. Particulate matter was composed mostly of sulfuric acid; the non-sulfate portion of the particulate matter was composed of carbonaceous material and aluminum and iron oxidation products. No platinum was found in the particulate matter. |
