Continuous Measurement of Diesel Particulate Emissions

Field measurement of diesel particulate matter emissions.

A primary means to reduce environmental levels of diesel particulate matter (DPM) exposure to miners is to reduce the amount of DPM emission from the engine. A quick and economic method to estimate engine particulate emission levels has been developed. The method relies on the measurement of pressure increase across a filter element that is briefly used to collect a DPM sample directly from the...

Measurement of vehicle particulate emissions.

A constant volume sampler (CVS) compatible auto exhaust particulate sampling system has been built which samples exhaust isokinetically at constant temperature. This system yields internally consistent results and is capable of frequent and convenient operation.

Particulate emissions from diesel engines: correlation between engine technology and emissions

In the last 30 years, diesel engines have made rapid progress to increased efficiency, environmental protection and comfort for both light- and heavy-duty applications. The technical developments include all issues from fuel to combustion process to exhaust gas aftertreatment. This paper provides a comprehensive summary of the available literature regarding technical developments and their impa...

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...
