Project description
The current vehicle fleet in Finland is a mixture of new and old engine technologies with the mean age of a passenger car being about 11 years. Vehicles currently operating have passed the new vehicle standards in terms of regulated pollutants of the year of manufacture. However, we do not know whether emissions have increased due to usage. Also it is unknown, how big source of gaseous emissions as well as primary and secondary particles each vehicle type is. The information of real-world emissions is collected from new measurements for a hundred vehicles especially by chasing them with a mobile laboratory van or by measuring directly from the tailpipe with a PEMS system. The new results are coupled with existing particle emission data of TUT and FMI. The work will be done in collaboration with Finnish Meteorological Institute, Lund University, and Aristotle University of Thessaloniki. As a result, a new emission database is created consisting of various branches of tailpipe emissions.
