Characterization of the sooting tendency of diesel fuels by shock tube and engine experiments 2001-24-0040
The sooting tendency of a diesel fuels matrix has been
investigated in a single-cylinder DI engine and in a shock tube.
Soot loading in the optically accessible was inferred using
two-color pyrometry.
The engine was operated at 1250 rpm and 5 bar imep. Shock tube
tests were performed in pure pyrolysis conditions; in the
temperature and pressure range 1600-2400 K and 7-13 bar,
respectively. The soot formation process was followed by means of
light extinction methods. A thorough analysis of the results
provided meaningful indications of fuels'
""performances,"" allowing to assess the effect
of the fuel's composition (aromatics contents, cetane number,
oxygen contents) on its sooting tendency.
