1. Volvo Technology AB / Volvo Technology Corporation Dept. 6700 / UW / 25/10/2015 / page 1 Particulates, Brussels, January 2003 PARTICULATES Major Scientific Objectives To review the instrumentation and sampling techniques used so far for particulate characterisation To develop a harmonised sampling protocol To use this protocol in a detailed measurement campaign To produce an adequate database with appropriate emission factors for particulates and other unregulated pollutants associated with them  These emission factors and the associated methodology will address both the baseline of current vehicles and fuels and the future emission reduction (mainly aftertreatment) techniques, including enabling conventional and alternative fuels, envisaged by the industry for compliance with the already decided emission standards for 2005 and beyond.

Volvo Technology AB / Volvo Technology Corporation Dept. 6700 / UW / 25/10/2015 / page 2 Particulates, Brussels, January 2003 Task 630: Final summary report In this task it is foreseen to produce a final report which will summarise the experience gained in the course of the project and which will address the following issues in particular:  Particulate measurement outline.  Current fleet emission status.  New technologies emission reduction potential.  Summary discussion for future legislative demands.

3. Volvo Technology AB / Volvo Technology Corporation Dept. 6700 / UW / 25/10/2015 / page 3 Particulates, Brussels, January 2003 Two Adequate ”Databases” 1. Aggregated Data  The storage of relevant data in order to facilitate immediate as well as future analyses  This ”database” will consist of a great number of individual files named according to a pre-defined name format  The actual in-depth analyses of these data will not be part of the Particulates project  The partners having contributed to these data will also have access to them 2. Selected Particulates Data (emission factor-related)  Focus on factors covering a full driving circle  Perform statistical analysis  Extract data relevant for the calculation of emission factors
