The paper considers the principles of catalyst operations and chemical reactions proceeding within. Also, the modes used for defining the efficiency of the catalyst are reviewed. Experimental investigation has been carried out to help with assessing the efficacy of the catalyst according to the concentration of noxious fractions and differences in temperature before and behind the catalyst. Nine Otto engine vehicles have been tested. The applicable contamination level and efficiency of catalyst performance of the vehicles have been set. The conclusion reveals that flowing gas temperature within the vehicle having an effectively performing catalyst is always lower than out flowing gas temperature.
