Soot Concentration and Particle Size in a DI CR Diesel Engine by Broadband Scattering and Extinction Measurements 2005-24-013
Actual emission legislation limits strongly the amount of
pollutant in the atmosphere from internal combustion engine. In
particular diesel engines widely emit NOx and particulate matter
(PM). The last one has principally a carbonaceous nature and
presents micronic and submicronic particles extremely dangerous for
human health since it could deposit in the lung.
In this work, a technique based on broadband ultraviolet (UV)
visible scattering and extinction is applied inside a transparent
DI CR diesel engine in order to analyze the soot evolution and
oxidation. The study is carried out with particular detail for
different injection strategies characterized of two and three
injections per cycle, Pre+Main and Pre+Main+Post, considering the
late combustion before the exhaust stroke. The analysis is
performed in terms of size, mass concentration, and chemical and
physical nature. The UV-Visible spectral range is chosen
considering that the main pollutant precursors like aromatic
compounds and carbonaceous matter present strong absorption band in
this range.
