SOME ASPECTS OF THE MEASUREMENT OF DIESEL EXHAUST SMOKE

The measurement of the exhaust smoke of diesel engines meets with some difficulties. Within the scope of the opacimetric method and with reference to two types of instruments that seem particularly well-suited to the task, the present paper assesses the problem in its most significant aspects. Namely there are the calibration and operation of opacimeters both in static and dynamic situations, their most judicious mode of installation, and the extent to which measurements obtained with different instruments can be correlated. Some new results are obtained; it is substantiated, e.g. that opacity depends on the exhaust-gas temperature according to a certain law, and therefore useful recommendations can be formulated for the adoption of a particular instrument and its most appropriate use, depending on the type of test to be carried out.
