Optical diagnostics for diesel engine applications: Quarterly technical progress report, 1 April 1985 to 30 June 1985

OSTI ID:6635512
A prerequisite to diesel combustion research, for the purpose of developing soot emission control strategies, is the capability of making in-situ diagnostic measurements that characterize the soot formation and oxidation processes. Measurements of the thermochemical state of the combustion mixture are required, including temperature and species concentrations. These observations are then to be related to independent measurements of soot particulate evolution and growth. To date, several different diagnostic techniques have been successfully implemented in flame and spark ignition engine environments, such as Coherent Anti-Stokes Raman Spectroscopy (CARS) and simple absorption/Mie scattering, to measure such parameters. However, several practical problems may prevent implementation of these diagnostic techniques in the high-pressure, soot-laden environment typical of diesel combustion chambers. The objective of this program is to explore some of these problems and the limits of applicability of CARS and extinction/scattering diagnostics to diesel combustion research.
