Abstract

We present quantitative, in-cylinder, UV-laser-induced fluorescence measurements of nitric oxide in a heavy-duty Diesel engine. Processing of the raw fluorescence signals includes a detailed correction, based on additional measurements, for the effect of laser beam and fluorescence attenuation, and for the pressure and temperature dependence of the fluorescence efficiency, based on numerical modelling. These corrections are largest early in the stroke, when quenching rates are high and UV transmission is low. Together, they vary over more than three orders of magnitude during the combustion stroke. Fully quantitative results are realised by an overall calibration using independent concentration measurements in the exhaust gas. The data provide evidence of NO formation during both the premixed and mixing-controlled combustion phases. (C) 2006 The Combustion Institute. Published by Elsevier Inc. All rights reserved.
