Abstract

In this paper, the Laser Raman technique for the measurements of the species concentration of the gages exhaused from I.C Engines is presented. An application of the method for oxygen concentration by Raman spectroscopy has been made. Experimental data obtained using He-Ne laser bean with 632.8 nm wave length 29 a source are presented and compared with conventional method for analysis. The main parameters and outline of the apparatus are described. An oxygen analyzer has been used to evaluate the results. The results show a good agreement as compared with the results measured by the oxygen analyzer. The Laser-Raman technique proved very rapid for measuring the species concentration of the exhaust gages. For example, the measuring time when using the oxygen analyzer ls approximately 2-3 minutes, while by Raman technique is slightly more than the response time of the photodiode detector which is approximately 250 nano seconds. The problems associated with this experimental work are the low cross section area of Raman scattern, the low laser power and the low sensitivity of the amplifier.
