23 Conclusions Wide primary particle diameter range 7 to 60 nm Indicative of heterogeneous fuel and air mixing Other speed and load points should be examined Small primary size relative to diesel for minimum PN injection point 10 to 15 nm Fuel and air mixing enhanced in some zones Presence of single solid particles smaller than 23 nm TEM number concentration data consistent with SMPS for this size range May be of health concern since can deposit in alveolar region and have greater percent surface area 23 Managed by UT-Battelle
