Abstract

1,226,911. Photo-electric analysis of exhaust gases. DAIMLER-BENZ A.G. Feb.14, 1969 [Feb. 14, 1968], No. 8240/69. Heading G1A. In the analysis of the combustion gases of an internal combustion engine, the volume rate of flow of one particular component of the combustion gases is obtained by first measuring the quantity per unit time of the exhaust gases from the engine using a photo-electric fan-wheel anemometer 11, 12, 13 and secondly measuring the concentration or proportion in the exhaust gases of the component of interest, using an infrared analyser 16 having a probe 15 in the exhaust pipe, and multiplying together voltages representing these two measurements. The output of the anemometer is a series of pulses the frequency of which is representative of the rate of flow. A frequency -to -voltage converter 14 is used to generate a measurement voltage which is applied to sequence potentiometer 19. The output of analyser 16 is applied to a potentiometric recorder which records the concentration of the component of interest, e.g. carbon monoxide or dioxide, and which controls sequence potentiometer 19. The take-off voltage at 21 representative of the rate of flow of the component of interest is applied to an indicator or recorder 22. The exhaust gas flow may be indicated or recorded separately at 24. A delay device (electrical, ultrasonic or magnetic) introduced at 26 or 27 may be provided to follow very rapid variations in exhaust gas composition changes, when a time lag between the two individual measurements is not acceptable.
