Please enter a number less than or equal to 1. They are often used to evaluate smoke emissions in locations outside the laboratory, such as in maintenance shops or in the field. We may receive commission if your application for credit is successful. See all jrmotorservices has no other items for sale.

Smoke opacity readings generally do not correlate well with other PM measurement parameters. Smoke has also been measured by filtering a fixed volume of exhaust gases through a filter paper and the smoke stain thus formed is evaluated on a grayness scale by a light reflectance meter Bosch smokemeter.

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.

Watch list is full. This item will be sent through the Global Shipping Programme and includes international tracking. The NO 2 cross-sensitivity could be eliminated by switching to a different light wavelength, e.



They appear to hold promise for application to newer engines with much lower particulate emissions, including engines fitted with particulate filters. Accepted, Eligibility for PayPal Credit is determined at checkout. Skip to main content. Subject to credit approval.

In fact, the smoke opacity measurement is the only relatively low-cost and widely available method to measure a PM-related emission parameter in the field. The actual VAT requirements and rates may vary depending on the final sale. International postage paid to Pitney Bowes Inc. Visit my eBay shop.

Higher combustion rates are obtained by increasing fuel air mixing through use of high swirl rates, by increasing injection rate and improving fuel atomization.
