Title: Fibre optic sensor for diesel engine smoke measurement

Abstract: A portable fibre optic sensor for diesel smoke measurements is described. The sensor works by sampling the smoke on the surface of a gluing white tape and measuring the diffuse reflectance from the stained tape. The precision of the detector system was 0.2%. The sensor values of diesel smoke (Rs) were compared with the results obtained using a Bosch smokemeter (Bn). A plot of Rs against Bn yielded a straight line with correlation coefficient of 0.983. Values of Rs were also expressed as a function of diesel smoke concentration. The sensor can perform continuous and remote measurements. It is of simple construction and operation and is particularly useful for on-road measurements. (C) 1997 Elsevier Science S.A.
