TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
We propose to develop a sensitive PM measurement instrument to determine soot particle mass distribution from aircraft engine exhausts as well as from other IC engine emissions. Fundamental of the proposed technique is to measure particle charge under an electric field. Through extensive experimental and theoretical investigation on soot emissions from IC engines over the past four decades, it has been well-known that engine soot particles are usually charged. Counting particle charge at specific mass could lead to the determination of both total particle count and mass. Currently commercially available electrometric measurements on charged particles suffer from rapid signal drift, which limits its applications on soot emission measurements. In our proposed design, an amplitude modulation scheme is included to eliminate the background signal drift and also improve detection sensitivity. The proposed soot mass distribution monitor will be approximately 50 pounds in weight and consume approximately 300W electrical power. It will also be capable of being remotely controlled and operating under vacuum condition. Total cost of the proposed device could be less than $30,000.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The primary NASA need for this technology is to measure soot particle mass distribution from aircraft engine exhaust. At present, particle mass distribution is calculated from particle size distribution, which is measured by the Engine Exhaust Particle Sizer (EEPS) and Scanning Mobility particle Sizer (SMPS) techniques. Both techniques provide information on particle count at each electrical mobility diameter. To calculate particle mass distribution, an assumption of particle density becomes necessary. Since engine soot particles are intrinsically fractal aggregates, their densities are complex function of particle size and compositions. Obtaining the particle density information requires sophisticated measurement instrumentation. The proposed soot mass distribution monitor will directly measure particle mass distribution, from which total particle count and mass could be determined. In the past, NASA has funded a number of field measurement programs such as EXCAVATE, APEX, UNA-UNA, and AAFEX that focus on the measurement of black carbon emissions from civilian aircraft engines.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
We expect that the soot particle mass monitor developed under this program will significantly benefit the scientific community interested in characterizing soot particle mass from a variety of internal combustion engines. The ability of one instrument to measure particle charge at specific mass will enable continuous measurements of particle mass distribution that can be directly used to determine total particle count and mass. In combination with an electrical aerosol charger, either with a radioactive source like 85Kr or non-radioactive source like corona discharge, this instrument will provide a direct measurement on particle count and mass simultaneously for any particles or aerosols. This measurement technique could be applied to ambient aerosol monitoring, PM emission detection, and particle manufacture process.
