The purpose of the study reported here was to investigate the applicability of monolithic honycomb catalysts for exhaust gas purification on small two-stroke engines. Investigations were carried out to assess the relations between operating conditions and the catalysts' CO- and HC converstion efficiency and to optimize conversion efficiency under stationary and transient engine operating modes. Furthermore, the influence of a catalyst on smoke emission was investigated as were the aging characteristics of various catalysts under European operating conditions with the engine running on leaded fuel
