This paper evaluates the performance of monolithic automotive exhaust catalysts under conditions of actual customer usage. Based upon the results obtained for the 450 catalyst equipped vehicles, it was concluded that the monolithic type catalyst is an efficient device for reducing hydrocarbon and carbon monoxide emissions in customer usage. The effects of accumulated vehicle mileage, engine maintenance, three alternate catalyst designs, catalyst over-temperature. partially melted catalysts, misfueling with leaded fuel, and vehicular accidents on the performance of the catalyst system are discussed. /GMRL/
