They appear to hold promise for application to newer engines with much lower particulate emissions, including engines fitted with particulate filters.
There are two groups of instruments: Smoke emissions increase with increase in smoje 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. Numerous correlations between opacity or smoke readings and PM mass that have been developed can provide only approximate results. Have one to sell?

Westbury, Wiltshire, United Kingdom. The NO 2 cross-sensitivity could be eliminated by switching to a different light wavelength, e. Smoke emissions can be reduced by accelerating combustion. This metsr is subject to change until you make payment.
