Abstract
Describes results of a study in which a light–duty engine Volvo D5 was run with gasoline to demonstrate that high–octane number fuels, in compression ignition engines, are able to achieve high efficiency, low NOx and soot simultaneously.
Researchers developed an advanced three stage injection strategy.  They then performed a load sweep between 6 and 17 bar IMEP and 2000 rpm.  They report that gross indicated efficiency stays fairly constant at 47% with very low NOx and soot.
