CATALYTIC EMISSION CONTROL SYSTEM FIELD TEST PROGRAM

A fleet of nearly 250 cars equipped with experimental catalytic converter systems were tested in taxi, police, state, and municipal fleets in various cities throughout the country. Test results showed that on the average the systems successfully controlled emissions to below the 1975 Federal and California requirements for greater than 50,000 miles. Engine misfire conditions did cause converter damage in some instances. Systems designed for the low emission requirements of 0.41/3.4/0.40 grams/mile HC/CO/NOx exceeded those levels at relatively low mileage due to catalyst deterioration. /GMRL/
