用LaVision公司以增强型CCD相机为核心部件构成的PLIF激光诱导荧光成像系统定量地测量了柴油发动机中NO自由基的激光诱导荧光成像并进行了数据后处理。
The imaging of in-cylinder NO distributions in a
steadily running optically accessible diesel engine operated
on standard diesel fuel is performed by means of the 2DLIF
technique and a tunable ArF excimer laser at 193 nm.
Simultaneous excitation at 226 nm showed that no sizable
photo-chemical effects are induced by the excimer laser. In
order to account for the gradually decreasing transparency of
the windows due to soot deposits and for the in-cylinder attenuation
of the laser intensity, signal processing procedures for
the imaged distributions are presented. In addition to the more
realistic depictions of NO distributions at selected crank angles
and loads resulting from these procedures, the latter are
an essential step towards a quantitative interpretation of the
corresponding in-cylinder NO concentrations.
