Abstract
An optical method for the simultaneous determination of species concentration and temperature in a high pressure transient combustion and expansion process is described. The experimental system utilizes a mechanically chopped (2000 Hz) external radiation signal to perturb the self-emission signal from the combustion gas of an internal combustion engine. Distinguishing between the emission and absorption signals simultaneously provides a capability for determination of species concentration by absorption and of optical temperature by an emission-absorption technique.Keywords
