Authors Abstract
Content
Two types of catalysts were tested in a fleet of twenty-four 1969 vehicles, operated in customer-type urban driving regimes, on both leaded and nonleaded fuels over a period of 18 months. The two catalyst types and the converter systems chosen for this evaluation were selected on the basis of information obtained from an earlier test program involving four cars that were durability tested on a more rapid “test track mileage accumulation cycle.”
Comparisons are made between the vehicles running rapid mileage accumulation and the vehicles running slower customer-type mileage accumulation. Catalyst life and system performance depreciation were relatively similar in both fleets and did not seem to be significantly affected by the method of mileage accumulation.
The 24-vehicle fleet was equipped with a programmed protection system (PPS) designed to protect the catalysts from damage due to over-temperature operation. Problems with this prototype protection system are discussed.
