DIESEL SMOKE MEASUREMENT – (Progress Report of the Smokemeter Group of the Diesel Fuels Division, Coordinating Fuel and Equipment Research Committee, CRC) 560060

IN response to numerous complaints against the CRC (photoelectric) smokemeter, the CFR Diesel Fuels Division in 1952 set up a project (1) to consider the objections raised, and (2) to review other instruments for measuring smoke in diesel exhaust. Its objective was to recommend a more suitable type of instrument, which would overcome some operational objections to the CRC smokemeter.
Of the several makes of commercial instruments considered, one make has been tested cooperatively and found superior in several respects to the CRC smokemeter. An interim report on the CRC project is presented in which directions for its use and precautions to be observed in order to get optimum satisfaction from the continuous, filtering-type, tape-recording smokemeter are given.
