Abstract |
A group of test programs were performed on current passenger cars to assess the rate of catalyst deterioration due to misfueling with leaded gasoline. These programs addressed both 'casual' misfueling as well as intentional misfueling. Recovery of the catalyst upon return to unleaded fuel was also assessed. On the average, one tankful of leaded gasoline was found to triple hydrocarbon (HC) emissions while causing emissions of carbon monoxide (CO) to double. Continued use of leaded gasoline in vehicles designed to meet 1980 Federal Emission Standards resulted in HC and CO emissions increasing to levels which exceeded 1975 Federal Standards. Return to unleaded fuel resulted in recovery of some catalytic activity on slightly poisoned vehicles although continued use of leaded fuel resulted in a permanent loss of catalytic activity. |
