Název v původním jazyce

Assessment of a Low-Cost Portable Proportional Exhaust Sampling System for Gravimetric Particulate Matter Emissions Measurement

Popis výsledku v původním jazyce

Particulate matter (PM) is considered to be the most harmful component of internal combustion engine exhaust to human health. At decreasing levels of total PM mass, its measurement is challenging, requiring either a full-flow dilution tunnel or a fast-response, variable dilution ratio sampler. To allow for such measurements on the road and in lesser equipped laboratories, a low-cost proportional sampling system has been developed. The system uses a pair of mass flow controllers, one of which meters filtered air into a heated miniature partial-flow dilution tunnel, and the other one regulates the flow of diluted exhaust through a filter on which PM is sampled. Results obtained with this system during transient tests fall, after corrections for measurement bias, within a factor of two of measurement obtained with a full-flow dilution tunnel.
