3. Volvo Technology AB / Volvo Technology Corporation Dept. 6700 / UW / 03/11/2015 / page 3 Particulates, Lemnos, 2003 Background A first selection of results related to particle emissions, differences between generations of vehicles and engines as well as effects of aftertreatment equipment (particle traps) ”A first feeling of the data” A detailed analysis of fuel effects will be available in a separate document (deliverable 14) It was not possible to analyse how combustion parameters such as injection pressure, EGR rate, boost pressure, pre- injection and post-injection influenced the particle emissions. Little information on ”future engine technologies”  Look at previous trends, Euro I to Euro III etc. More data available on exhaust aftertreatment technology  HD: Continuous Regeneration Trap (CRT) LD: Diesel particulate filter(DPF) Based on a ”first version” of the database

Update the report  Aftertreatment effects might need more detailed analysis? Focus on general trends (complete driving cycles etc.) Contributions can be sent to Volvo Detailed analysis in reports from individual labs (or scientific papers to come)
