Nanoparticle Emissions of a DI 2-Stroke Scooter with Varying Oil- & Fuel Quality 2005-01-1101

Limited and nonlimited emissions of scooters were analysed during several annual research programs of the Swiss Agency of Environment Forests and Landscape (SAEFL, BUWAL)*).
Small scooters, which are very much used in the congested centers of several cities are a remarkable source of air pollution. Therefore every effort to reduce the emissions is an important contribution to improve the air quality in urban centers.
In the present work detailed investigations of particle emissions of a Peugeot scooter with TSDI (Two Stroke Direct Injection) were performed.
The nanoparticulate emissions with different lube oils and fuels were measured by means of SMPS, (CPC) and NanoMet *). Also the particle mass emission (PM) was measured with the same method as for Diesel engines.
It can be stated, that the oil and fuel quality have a considerable influence on the particle emissions, which are mainly oil condensates. Not all influences can be explained and more detailed knowledge about the oil composition and about the used additive packages is necessary.
The use of non active catalyst leads to strongly increased particle emissions values, both mass and counts.
Since the particulate emission of the 2-S consists mainly of lube oil condensates the minimization of oil consumption stays still an important goal.
