Summary:

Some methods to quantify the soot concentration by Laser-Induced Incandescence were developed using a flat flame burner in our previous work [1]. Those methods take the following points into consideration. (1)a correction of the LII signal intensity profile distorted by the laser attenuation due to soot clouds on the laser path, (2)a correction of the LII signal intensity attenuated by soot clouds between a camera and a measurement plane, (3)soot particle sizing up using 2-color LII signals and (4)conversion from a signal intensity to a soot concentration based on a calibration data. Using the methods, the accuracy of less than 10% was achieved in soot concentration measurement by a flat flame burner.In this study, the above methods were applied to an optically accessible single-cylinder diesel engine to measure in-cylinder soot concentration quantitatively. The detailed investigations based on the sequences of spatial and temporal quantitative images reveal the following points
