The composition of diesel exhaust was determined by infrared spectra, colorimetry, gas chromatography and fluorescence studies. A group of panelist were enclosed in a room constructed to maintain a constant very low odor level with temperature and humidity control. To establish odor thresholds, ...
2.1 Composition of particulates Diesel exhaust is a complex mixture of organic and inorganic compounds and gas, liquid, and solid phase materials. Diesel particulates consist of an elemental carbon core with several organic compounds (soluble and insoluble in organic solvents), sulfates, nitrogen oxides...
Nucleation Particles in Diesel Exhaust: Composition Inferred from in Situ Mass Spectro- metric Analysis; Environ. Sci. Technol. 2005, 39, 6153-6161. 43. Park, K.H.; Cao, F.; Kittleson, D.B.; Mcmurry, P. Relationship between Particle Mass and Mobility for Diesel Exhaust Particles; Environ...
Special emphasis is laid on the role of mixture formation systems, catalysts and gas composition for natural gas engines. Regarding future emission legislation the potential of diesel, gasoline and natural gas fuels will be evaluated. New technical solutions will be taken into account and their ...
PURPOSE:To perform the regeneration of a filter simply and accurately by installing a recollecting part for exhaust gas particulate in an exhaust gas passage at the upstream side of a filter body, while installing a device which generates a backwash air flow in multiple cells in the filter body...
These aspirated gas mixtures were pilot-ignited by diesel fuel, while the engine load was varied between 0 and 7 bar IMEP by only adjusting the flow rate of the aspirated mixtures. The in-cylinder gas composition was also investigated when combusting CH4-CO2 and CH4-CO2-H2 mixtures at ...
were characterized in terms of crystalline phase identification (XRD), specific surface area (N2 adsorption–desorption at −196 °C), reducibility and oxidation state of transition metal ions (H2-TPR), quantification of adsorbed oxygen species (O2-TPD) and surface elemental composition (XPS)....
While emissions reduction efforts have often focused on changing engine design or improving aftertreatment, diesel fuel modifications can also play an important role in improving engine efficiency and reducing exhaust emissions. The aim of this work was to examine the potential for emissions reductions ...
Systems and methods for removing carbon dioxide from gas, e.g., diesel exhaust gas, are provided. The systems involve uptake of carbon dioxide by algae in water to which the gas is exposed. Inventors: De Mattia, Jim (Brawley, CA, US) ...
