Gasoline Partially Premixed Combustion: High Efficiency, Low NOx and Low Soot by using an Advanced Combustion Strategy and a Compression Ignition Engine

摘要

A light-duty engine Volvo D5 was run with gasoline to demonstrate that\udhigh-octane number fuels, in compression ignition engines, are able to achieve\udhigh effi ciency, low NOx and soot simultaneously. An advanced three stage\udinjection strategy was developed. A load sweep was performed between 6 and\ud17 bar IMEP and 2000 rpm. Gross indicated effi ciency stays fairly constant at\ud47% with very low NOx and soot. In the second section of the paper, diesel was\udcompared with gasoline, while in the fi nal part the commercial 140°UA nozzle was\udcompared with the narrower one, 120°, used in the above-mentioned experiments.
