• Description:
  Diesel Particulate Matter (DPM), a probable human carcinogen, is one of the largest contributors to ambient PM pollution in urban areas around the world. Emission standards for DPM are becoming more stringent, and likely cannot be met well-into the future with only with modifications to the fuel and engine. The objective of this study was to design and construct an electrostatic precipitator (ESP) to capture DPM from diesel exhaust. A compact laboratory system for the generation, sampling, and analysis of diesel particulate matter was constructed to test the performance of the ESP. DPM was produced by a 6.5 kW diesel-powered electric generator and directed to the ESP through a short section of galvanized steel pipe after the muffler. Mass removal efficiency of the ESP by sampling through a stainless steel cassette and collecting the DPM on Teflon filters. The efficiency was measured while the engine was running idle and at medium load. Two different types of diesel were tested to investigate the effect of fuel type on the efficiency. The results showed that the ESP provides 60-85 percent reductions with both load conditions. The efficiency of the ESP with the engine running on ULSD was between 7 to 18 percent lower than LSD. , the ESP worked with less sparks when ULSD was used. [Description provided by NIOSH]
