Diesel engine oils have more severe demands made on them in service than do gasoline engine oils. two diesel combustion products that lead to rapid oil deterioration are carbonaceous particulates and no2. both these products are strongly operating mode dependant, therefore, to specify an oil change… More

Furnaces designed to operate on liquid fuels have radiation as the main mode of heat transfer, they also have limited turn-down ratios. flame emissivities for oil and natural gas in industrial applications have been measured as 0.55 and 0.15 respectively. therefore, due to the naturally low… More

The escape of hydrocarbons froma variety of sources can present a health safety problem. this proposal is for research funds to explore a flameless ionization concept to detect such gases. small quantities of hydrocarbons (e.g. 0.03% v/v) in either air or rare gases can generate large penning… More

Many combustion experiments involving particle sizing and radiation measurement require an accurate knowledge of the refractive (n) and absorption (k) indices of soot. even though soot is a complex hydrocarbon with a particularly high c:h mass ratio, values for n and k for carbon are oftenused as… More

The work proposed in this study will take results from cfr laboratory research of engine oil degradation and apply it to the army's requirement for an engine-mounted sensor. the basic concepts proposed use specific wavelength ranges in the infra-red to detect degradation patterns most specifically… More
