“…These levels are comparable to those reported by Siegl et al (1994) for high and low emitting gasoline vehicles, but are slightly less than those reported by for high emitting gasoline vehicles in Nevada. The distribution of PAHs for gasoline vehicles is similar to that reported previously (Siegl et al, 1994;Sagebiel et al, 1997) with naphthalene, 2-methylnaphthalene, l-methylnaphthalene, and dimethylnaphthalenes being primary constituents. The distribution of PAHs for diesel vehicles differs from that of the gasoline vehicles primarily in that it includes lower relative concentrations of naphthalene and methyl-naphthalenes.…”

“…Several studies have shown that particulate emission rates from properly functioning/modem gasoline-fueled vehicles are small-i.e., on the order of 2-10 mghni (lkrnrnerle et al, 1991;Siegl et al, 1994;Zinbo et al, 1995). Studies of in-use vehicles indicate somewhat higher particulate emission rates.…”

“…The mean value was 0.60 mg/mile, and the standard deviation for the six cars was 0.17 mg/mile. 0.60 mg/mile was lower than results reported for earlier model vehicles [2][3][4][5] and was substantially below the regulated level of 80 mg/mile. The phase-by-phase results show that phase 1 dominated PM emissions, much as it typically does for HC, CO, and NO x .…”

“…A study of the effects of methylcyclopentadienyl manganese tricarbonyl (MMT) on vehicle emissions 4 from the early 1990s also reported PM emissions using base fuel at less than 5 mg/mile. A study of both normal and malfunctioning vehicles 5 using an industry average fuel showed that the normal vehicle PM emission rate was 6 mg/mile, while the malfunctioning vehicle produced PM emission rates between 25 and 40 mg/mile. A similar study using California reformulated fuel 6 found PM emissions for a 1990 model year vehicle to be in the range of 2-6 mg/mile for both normal vehicle operation and selected malfunctioning modes.…”

The impact of high-particulate-emission vehicles on the total light-duty vehicle particulate emission inventory in the South Coast Air Quality Management District (SCAQMD) has been estimated by an analysis of the SCAQMD's CUT-SMOG database, a field survey of smoking vehicles, and particulate emissions testing of representative smoking vehicles. The field study, carried out at 61 sites throughout the SCAQMD, showed that 1.11%-1.75% of the vehicles in the light-duty fleet emit visible smoke. This fleet of smoking vehicles is composed mainly of older vehicles, 8 to 18 years of age. Particulate emission testing of 23 smoking vehicles gave an average Federal Test Procedure (FTP) weighted emission rate of 399 mg/mi with a range of 64-2,323 mg/mi, while the average IM240 emission rate was 346 mg/mi, with a range from 13-1,807 mg/mi. The contribution of light-duty smoking vehicles to the IMPLICATIONS Understanding the population density and emission characteristics of high-emitting vehicles has been found to be an important element in improving mobile source emissions inventories. For gaseous emissions, much progress has been made in this area through the use of remote sensing and follow-up dynamometer studies. To date, no attempt has been reported to define the population of highparticulate-emission vehicles, their characteristics, and emission rates. This paper reports results on the population and characteristics of high-particulate-emission lightduty vehicles as determined by a field study to identify visibly smoking vehicles in the South Coast Air Quality Management District. Particulate emission rates for a representative fleet of these vehicles were determined, and estimates were made of the contribution of these vehicles to the particulate emission inventory in the district. This updating and improvement of the particulate emissions inventory for the district will allow improved air quality management.particulate emissions inventory in the SCAQMD is estimated to be 0.51-0.81 tons per day.
