The particulate emissions
from tire and brake wear were estimated using (EMEP/Air method)
The filterable particulate emissions
were extremely low due to the advanced emission controls employed at the plant.
In the first-generation system, a solenoid-actuated injector was used to activate a single, far away, pilot injection to control combustion noise with limited particulate emission
We found that the only testing variable that reduced particulate emissions
was use of a diesel particulate filter, and these reductions of more than 90 percent were similar for both the hybrid and conventional diesel bus types," said Holmen.
Early compliance was achieved by permanently retiring 181 trucks, deploying 415 trucks that operate on clean-burning natural gas and retrofitting 794 trucks with "best available control technologies"--special pollution controls such as oxidation catalysts or filters--to reduce harmful particulate emissions
Introduction of a particulate emission
limit for petrol cars using lean-burn direct injection technology
For instance, during a long period of coasting, particulate emissions
varied considerably and averaged 8.
Four boilers at the two plants allegedly exceeded Virginia's allowable particulate emission
rates, according to the EPA's complaint.
has announced that testing of its Platinum Plus diesel fuel additive by recognized independent laboratories in the Netherlands and Switzerland had again confirmed the additive's ability to significantly reduce diesel particulate emissions
and improve the performance of diesel particulate filters.
Wood stove makers are producing a new generation of cleaner-burning stoves, which, studies show, have cut stove-produced pollution 85 percent in the last few years by reducing particulate emissions
to an average of six grams per hour.
The Forest Service is currently working to develop a computer model that can help evaluate the combined emissions from prescribed fire and wildfire under different levels of fuel treatment, and to help identify the amount of prescribed fire that might result in the lowest possible total of particulate emissions
Beginning with the 1993 model year, bus manufacturers would have to reduce the vehicles' particulate emissions
by 60 percent -- to 0.
