heal.abstract	In the present work, the effect of the gradual deactivation of a three-way catalytic converter on the exhaust emissions was studied. The exhaust gases were analyzed for CO, HC (i.e. total unburned organic compounds), MTBE, methane and ethylene, before and after their catalytic treatment, in a wide range of engine operating conditions. The thermal aging of the catalytic converter resulted in an increase in the required time for the start of its operation and loss of its auto thermal operation. The catalytic efficiency was significantly decreased after each thermal aging step, especially at idle conditions. As a result, CO and especially HC emissions were increased, whereas ethylene and MTBE emissions were multiplied by a factor of 6-7 at 3.81 hp, in the case of the deactivated catalyst.
