The primary objective of this program was to establish vehicle operating modes during which a temperature rise across the catalytic converter could be measured and used for determining the catalyst activity. The results of twenty-five (25) vehicle tests are reported. Seventeen (17) vehicle tests were conducted using known good converters, six (6) using dead converters and two (2) using partially-active (lead-poisoned) converters. The test sequence consisted of a series of five engine operating modes. In general, with careful thermocouple attachment to the exhaust pipe surface at the inlet and output of the converter, active converters show a large enough temperature rise that they can be distinguished from dead converters.
