The evaluations and comparisons were conducted using sulfuric acid and hydrocarbon particles as model volatile particles in laboratory tests, and diluted exhaust from a diesel particle filter (DPF)-equipped heavy-duty diesel vehicle operated on a heavy-duty chassis dynamometer under steady speed conditions at two different engine loads. A number of different real-time particle number counters were used to make measurements of particle number (PN) with different particle size cuts. For comparison with laboratory findings, field comparison tests of a heavy-duty diesel vehicle were conducted on a chassis dynamometer over the urban dynamometer driving schedule (UDDS) cycle and on the highweay in flow-of-traffic driving conditions, including two uphill (phases 1 and 2) and two downhill (phases 3 and 4) segments.
