    • Effects of renewable fuel and exhaust aftertreatment on primary and secondary emissions from a modern heavy-duty diesel engine 

      Gren, Louise; Malmborg, Vilhelm B.; Falk, John; Markula, Lassi; Novakovic, Maja; Shamun, Sam; Eriksson, Axel C.; Kristensen, Thomas B.; Svenningsson, Birgitta; Tunér, Martin; Karjalainen, Panu; Pagels, Joakim (08 / 2021)
      article
      Compared to petroleum diesel, renewable diesel fuels and exhaust aftertreatment systems can reduce primary exhaust emissions that are hazardous to human health and the environment. Secondary aerosol emissions which form ...

    • Immersion freezing ability of freshly emitted soot with various physico-chemical characteristics 

      Falk, John; Korhonen, Kimmo; Malmborg, Vilhelm B.; Gren, Louise; Eriksson, Axel C.; Karjalainen, Panu; Markkula, Lassi; Bengtsson, Per Erik; Virtanen, Annele; Svenningsson, Birgitta; Pagels, Joakim; Kristensen, Thomas B. (09 / 2021)
      article
      <p>The immersion freezing ability of soot particles has in previous studies been reported in the range of low/insignificant to very high. The aims of this study were to: (i) perform detailed physico-chemical ...

    • Influence of fuel ethanol content on primary emissions and secondary aerosol formation potential for a modern flex-fuel gasoline vehicle 

      Timonen, Hilkka; Karjalainen, Panu; Saukko, Erkka; Saarikoski, Sanna; Aakko-Saksa, Päivi; Simonen, Pauli; Murtonen, Timo; Dal Maso, Miikka; Kuuluvainen, Heino; Bloss, Matthew; Ahlberg, Erik; Svenningsson, Birgitta; Pagels, Joakim; Brune, William H.; Keskinen, Jorma; Worsnop, Douglas R.; Hillamo, Risto; Rönkkö, Topi (24.04.2017)
      article
      <p>The effect of fuel ethanol content (10, 85 and 100 %) on primary emissions and on subsequent secondary aerosol formation was investigated for a Euro 5 flex-fuel gasoline vehicle. Emissions were characterized during ...

    • Particle emissions from a modern heavy-duty diesel engine as ice nuclei in immersion freezing mode: A laboratory study on fossil and renewable fuels 

      Korhonen, Kimmo; Kristensen, Thomas Bjerring; Falk, John; Malmborg, Vilhelm B.; Eriksson, Axel; Gren, Louise; Novakovic, Maja; Shamun, Sam; Karjalainen, Panu; Markkula, Lassi; Pagels, Joakim; Svenningsson, Birgitta; Tunér, Martin; Komppula, Mika; Laaksonen, Ari; Virtanen, Annele (02.02.2022)
      article
      <p>We studied ice-nucleating abilities of particulate emissions from a modern heavy-duty diesel engine using three different types of fuel. The polydisperse particle emissions were sampled during engine operation and ...

    • Time-resolved characterization of primary particle emissions and secondary particle formation from a modern gasoline passenger car 

      Karjalainen, Panu; Timonen, Hilkka; Saukko, Erkka; Kuuluvainen, Heino; Saarikoski, Sanna; Aakko-Saksa, Päivi; Murtonen, Timo; Bloss, Matthew; Dal Maso, Miikka; Simonen, Pauli; Ahlberg, Erik; Svenningsson, Birgitta; Brune, William Henry; Hillamo, Risto; Keskinen, Jorma; Rönkkö, Topi (14.07.2016)
      article
      <p>Changes in vehicle emission reduction technologies significantly affect traffic-related emissions in urban areas. In many densely populated areas the amount of traffic is increasing, keeping the emission level ...
