Cycle Resolved Measurements of Diesel Particulate by Optical Techniques 941948
The capabilities of the spectral extinction and scattering technique to follow the time history of the particulate concentration in the exhaust of a Diesel engine were evaluated. Simultaneous measurements of extinction and scattering coefficients from UV to visible were performed at 1.5 m downstream the exhaust valve. The measurements were triggered with the exhaust valve lift. The exhaust stroke was divided in three time windows of 1 ms in which the optical signals of 100 consecutive cycles were detected. The mean diameter, the concentration and the properties of soot particles were evaluated. The cyclic variation of measurements was also estimated.
