“…In the past, the negligible level of particulate matter at the exhaust of PFI SI engines addressed the research activities in other directions and the previous investigations were focused on the fuel deposition as cause of high level of exhaust hydrocarbon emissions during the cold start-up [15][16][17]. Nevertheless, recent experimental studies demonstrated the presence of high number concentration of nanometric carbonaceous particles at the PFI SI exhaust also at low engine speed [18][19][20]. These particles seem to be due to the diffusive flame near the valves.…”

“…When directly comparing PFI and DI engines with respect to PN emissions, a significant advantage for PFI is reported in the literature. 3,4 However, significantly high PN emissions were also observed for PFI through both engine dyno studies 57 and vehicle measurements. 8 Optical investigations in Merola et al 9 and Merola and Vaglieco 10 were performed on a single-cylinder engine, which gave clues to particulate formation occurring near the intake valves.…”

“…The detrimental health effects of particulate matter and ultrafine particles are well known [1,2,3]. It is evident that DPF's do not get rid of all particles [4], and the trapping efficiency of ultrafine particles of current DPFs might be less than 70% [5], particularly during and shortly after regeneration [6,7,8], when the soot cake has been recently oxidized. DPF trapping efficiencies will increase in the future but will be limited by backpressure and fuel consumption penalties.…”
