The testing of four groups of cars for sulfate and sulfur dioxide exhaust emissions is described. The collection and analytical techniques used for sulfate and sulfur dioxide are described. Emissions rates in grams per kilometre are presented for a variety of test cycles. In addition to sulfates and sulfur dioxide, gaseous emissions of hydrocarbons (HC), carbon monoxide (CO) and oxides of nitrogen (NOx) are reported in grams per kilometre. Total particulate weight on the sulfate filter was determined on two of the groups of cars. For these same two groups of cars, the sampling tunnel residue from each test car was examined by x-ray fluorescent techniques. The first of the car groups was tested to characterize sulfate emissions from eight automobiles. Four of these were gasoline powered catalyst cars, three were gasoline powered noncatalyst cars, and one was diesel powered. The second group, four catalyst cars, was operated for 80,500 km (50,000 miles) to determine the effect of distance accumulation on sulfate emissions. The third group, two 1975 production catalyst cars, was part of the EPA sulfate procedural development testing. The last group, eight cars, was part of the EPA sulfate baseline. Of these cars, six were production 1975 models (including one diesel), and two were experimental cars with three-way catalysts.
