A practical estimate model of particulate matter loaded in diesel exhaust filters

Diesel Particulate Filters [subscription]

● Diesel Filter Regeneration Abstract: Diesel particulate filters capture particle emissions through a combination of surface-type and deep-bed filtration mechanisms, such as diffusional deposition, inertial d positi , or flow-line interception. Collected particulates are removed from the filter, continuously or periodically, through thermal regeneration. Diesel filters are very effective in co...

Q. Monitoring of Diesel Particulate Exhaust in the Workplace

Recent Developments in Plasma De-NOx and PM (Particulate Matter) Removal Technologies from Diesel Exhaust Gases

Industrialization of plasma De-NOx system needs combination of various technologies technologies. This article introduces these many technologies and discusses the technical problems and their solutions. Such technologies include system design, efficiency requirements, component design method, plasma chemical reactions, optimization of process, scheme of the system, modification of discharge mo...

Effects of particulate matter from gasoline and diesel vehicle exhaust emissions on silicate stones sulfation

The effects of particulate matter (PM) from diesel and leaded gasoline motor vehicles exhaust emissions on sulfation of granites, syenite and gabbro stones have been experimentally studied. Abundant gypsum crystals and corrosion features developed on stones covered with diesel PM (DPM) following 72 h exposure to 100 ppm SO2 at a relative humidity of 100%. In contrast, very small amounts of gyps...

Detailed characterization and profiles of crankcase and diesel particulate matter exhaust emissions using speciated organics.

A monitoring campaign was conducted in August-September 2005 to compare different experimental approaches quantifying school bus self-pollution. As part of this monitoring campaign, a detailed characterization of PM2.5 diesel engine emissions from the tailpipe and crankcase emissions from the road draft tubes was performed. To distinguish between tailpipe and crankcase vent emissions, a deutera...
