ABSTRACT:
Disclosed is a method and apparatus for determining the hydrocarbon conversion efficiency of a catalytic converter used in conjunction with an internal combustion (IC) engine to reduce the pollutants contained in the IC exhaust gas comprising the steps of: (a) determining the hydrocarbon content of the IC exhaust gas prior to its entry into the catalytic converter by sampling the exhaust and passing the sample to a catalytic differential calorimetric sensor; (b) contacting the catalyst in the converter with the IC exhaust; (c) determining the hydrocarbon content of the exhaust leaving the catalytic converter by sampling the exhaust and passing the sample to the catalytic differential calorimetric sensor; and (d) comparing the hydrocarbon contents of the exhaust samples from steps (a) and (c) and thereby determining the hydrocarbon conversion efficiency of the catalyst in the converter.
