Add to Watch list Watching Watch list is full. Numerous correlations between opacity or smoke readings and PM mass that have been developed can provide only approximate results. Smoke emissions increase with increase in engine load due to overall richer fuel-air ratios and hence, the rated engine power was specified based on the maximum permitted smoke density to curb black smoke emissions during engine operation.

Higher combustion rates are obtained by increasing fuel air mixing through use of high swirl rates, by increasing injection rate and improving fuel atomization. In view of the demands of advanced, low emission diesel engines, the following areas of concern can be identified in conventional smoke opacity meter technology:.

In general, smoke and opacity meters are much simpler some of them very simple and less costly in comparison to most other instruments used for PM measurement. Smoke opacity limits may be also included as auxiliary limits in new engine emission standards. As the diesel particulate matter PM mainly consists of soot and the adsorbed unburned hydrocarbons SOF on soot core, the PM content has been related to exhaust soot content and HC concentration as below.
