CRC Investigation of Diesel Smoke Measurement (Report of Smokemeter Group of the Diesel Vehicle Fuel, Lubricant and Equipment Research Committee of the Coordinating Research Council, Inc.)

Cooperative work on diesel smoke measurement has been conducted for more than twenty years. Results of this work have shown that smoke measurement can be reasonably exact if conducted properly. Application of experimental results and the experience of the Smokemeter Group of the Coordinating Research Council (CRC) are presented as the state-of-the-art, outlining techniques and guides necessary for acceptable smoke measurement. Information is provided on choice of smokemeter type, smokemeter operation, sampling, expression of data, and visual rating. The CRC Smokemeter Group recommends that this information be used as a basis for general work and communication in diesel smoke measurement.
