Summary:

An active oxidation catalyst is an efficient measure to reduce not only gaseous components (CO, HC), but also particle emissions (mostly oil condensates) of a small 2-stroke engine with lost oil lubrication.Since the 2- and 3-wheelers with 2-stroke propulsion are still a very serious source of air pollution worldwide in many urban areas, it is important to have a look on some consequences of an improperly working catalyst.The present paper shows some results of user-oriented aging of catalyst on the vehicle and results of limited emissions and unlimited (nano)particles during the catalysts screening tests.The works are a part of an international scooter network project, which was performed (2004 to 2007) in the Laboratories for IC-Engines and Exhaust Emission Control of the University of Applied Sciences, Biel, Switzerland with main support of the Swiss Federal Office of Environment (BAFU), Swiss Petrol Union (EV) and Swiss Lubes (VSS).A catalyst, which is polluted by oil overdosing, becomes a longer light-off time and lower conversion rates. A part of this deterioration is irreversible. An inactive catalyst causes clearly higher gaseous and particulate emission components
