Summary:

This study investigated the effects of various start of injection (SOI) timings on particulate emissions (PN) from fueling gasoline blends in a single cylinder direct injection engine. The particulates were measured in both raw exhaust and exhaust treated through thermodenuder (TD) acting as a volatile particulate remover. Three fuel blends containing no oxygen, ethanol (EtOH) of 10%(v/v), and ethyl tert-butyl ether (ETBE) of 22%(v/v) were prepared by blending corresponding oxygenates into commercial gasoline on a volumetric basis and were analyzed each fuel specification. Fuel blends were chosen to comply with the current European gasoline standard EN228. The engine was operated at a constant speed of 2000 rpm using stoichiometric homogeneous combustion at loads of 4.5 and 9 bar IMEP to comprehensively characterize the blends' effects on particulate number (PN) emissions. The use of oxygenated blends did not have a significant effect on PN emissions at low load but relatively increased them at high load, on an average. Additionally, solid PN (SPN) measurements showed that soot formation and emissions of volatile organic compounds (VOC) increased at high load for the blends
