Abstract
Since the ECE regulation 24 demands that diesel smoke of automobiles be measured with opacimeters or units yielding equivalent results, the smoke density of diesel engines was measured with opacimeters and filter units for comparison. Conversion tables, comparative curves, and calculations are provided permitting the conversion of grey tones into opacity units with an accuracy sufficient for practical use. The correlation of measurements obtained with the filters and opacimeters was studied during operation at constant full load and at free acceleration. A relationship could be found in most cases; however, it provided no basis for setting up correlations. Finally, smoke characteristics of induction diesel engines were compared with supercharged engines at different geographical altitudes, based upon practical road tests in the Grossglockner mountains. A linear smoke increase with increasing altitude or decreasing air density was observed.
