This work effort consisted of a series of emission and fuel economy tests on seven 1979 vehicles. The objectives of this effort were to assess the effect of operating a catalyst equipped vehicle on commercially available leaded fuel, to evaluate the emission characteristics of the vehicle at a point where gross catalytic poisoning and stabilization had occurred, to examine catalyst rejuvenation efforts, and to examine misfueling and rejuvenation effects on the oxygen sensor for vehicle equipped with a three-way catalyst. Each of the seven vehicle received a series of baseline tests, mileage accumulation tests using unleaded fuel, catalyst evaluation tests, mileage accumulation tests using leaded fuel and a final series of tests utilizing various combinations of fuel, catalyst status and oxygen sensor status.
