Measurements were made at 30-m downstream of a CFM56–2C1 engine for PM mass and number, particle size distribution, black carbon (BC), and volatile PM (sulfate + organics) using selected on-line instrumentation. The PM number emission index (EIN) ranged from ~ 2 × 1015 to 7 × 1016 particles/kg fuel burned depending on fuel flow, fuel composition, and sampling temperature with the magnitude of the emissions inversely correlated to fuel flow. The PM mass emissions (EIM) measured in the study varied from ~ 5 to 680 mg/kg fuel again depending on fuel flow, fuel type, and sampling temperature with a characteristic U-shaped curve of EIM with respect to fuel flow observed from the data. At low fuel flow (corresponding to low engine power), particle number and volume size distributions contained a single mode whereas at higher engine power, a bi-modal distribution was observed. The BC emissions varied from ~ 3 to 415 mg/kg fuel depending on fuel type and were found to exponentially increase with engine power (fuel flow). The volatile PM varied with sample temperature, fuel type, and increasing fuel flow within the range of EIs from ~ 0.4 to 11 mg/kg fuel with the highest values being at low fuel flow. Finally, the use of the two neat alternative fuels reduced the EIN by a median value of 70–73% and the EIM by ~ 94% as compared to JP-8 across all power conditions tested.

The new laboratory [Diesel Emissions Aerosol Laboratory (DEAL)] incorporates plumesampling capabilities which were based on a detailed flow field analysis using a combination of computational fluid dynamics modelling, flow visualization using smoke, streamers, and oil spots, and tracer gas measurements the results of which are described in the paper. The DEAL incorporates the unique ability to measure concurrently both the plume and the vehicular background which is generally not found in other on-road facilities.

The manual's organizational structure follows the steps to be taken in developing a cost-effective control strategy for fugitive particulate emissions. The procedural steps are the same whether the sources of interest are within a specific industrial facility or distributed over an air-quality control jurisdiction. the manual summarizes the quality and extent of published performance data for control systems applicable to open dust sources and process sources. In addition to presenting a cost-analysis methodology, the manual identifies primary cost elements and sources of cost data and presents a fully worked industrial example of cost-effective control strategy development.

Two organochlorine compounds, monochlorbenzene (MCB) and trichloroethylene (TCE), were cofired with fuel oil, followed by a natural gas fuel firing phase using only natural gas. The sorption and later desorption of uncombusted organic compounds on soot, (termed hysteresis) was the focus of the study. Soot samples and stack gases were analyzed for volatile and semivolatile organic compounds. A technique involving thermal desorption-GC/MS (gas chromatography/mass spectrometry) was developed and used for the combustion study soot analysis.

In this paper, a research program is described that directly determined both PM10 and PM2.5 (particles < or =10 and 2.5 microm in classical aerodynamic diameter, respectively) emission factors for mud/dirt carryout from a major construction project located in metropolitan Kansas City, MO. The program also assessed the contribution of automotive emissions to the total PM2.5 burden and determined the baseline emissions from the test road. As part of the study, both time-integrated and continuous exposure-profiling methods were used to assess the PM emissions, including particle size and elemental composition. This research resulted in overall PM10 and PM2.5 emission factors of 6 and 0.2 g/vehicle, respectively. Although PM10 is within the range of prior U.S. Environmental Protection Agency (EPA) guidance, the PM2.5 emission factor is far lower than previous estimates published by EPA. In addition, based on both the particle size and chemical data obtained in the study, a major portion of the PM2.5 emissions appears to be attributable to automotive exhaust from light-duty, gasoline-powered vehicles and not to the fugitive dust associated with reentrained mud/dirt carryout.
