Detection of Greenhouse Gas Precursors from Diesel Engines Using Electrochemical and Photoacoustic Sensors
The results indicate that the detection techniques used were sufficiently selective and sensitive to detect the gaseous species mentioned above in the ppmV range.
Evaluation of Nitrous Oxide Emitted from Diesel/Biodiesel Blends during Combustion in a Diesel Engine at Laboratory Scale by a Photoacoustic Spectroscopy Technique
The aim of this work was to evaluate the emission of nitrous oxide (N2O) using a diesel engine at laboratory scale without a catalytic converter with diesel/biodiesel blends (%) of 95:5 (B5), 90:10
Unconventional characterization of biodiesel from several sources by thermal lens spectroscopy to determine thermal diffusivity: Phenomenological correlation among their physicochemical and
Abstract Thermal diffusivity measurements of different oils and their respective biodiesels are investigated by means of thermal lens spectroscopy. The viscosities of biodiesel decrease by
Characterization of Biodiesel by Unconventional Methods: Photothermal Techniques
Atmospheric Pollution is one of the most concerning problems of modern society. The pollution of air can cause local and global impacts (Rockstrom et al., 2009, Steffen et al., 2003), modifying the
Em virtude do rapido crescimento e interesse na utilizacao do biodiesel, faz-se necessario obter metodos para padronizar e certificar a pureza do produto. Pretendemos realizar uma caracterizacao de
Detection of Ethylene Emitted by Diesel-biodiesel Engine Using CO2 Laser Photoacoustic Sensors
The increased use of modern society vehicles is rising the pollutant gas emissions causing several environmental and public health problem in urban centers. Diesel fuel is a major emitter of
Evaluation of Gaseous Emission in the Use of Biofuels in Brazil
In the seventies, the human society was faced with an important issue: the environmental problems. Is it possible to continue the exploitation of natural resources indefinitely? What to do with
Thermal Diffusivity Measurements of Biodiesel Fuel Using Thermal Lens Technique
In this work the Photothermal Technique, Thermal Lens (LT) is used to obtain the thermal diffusivity of different kinds of biodiesel. The absolute values of thermal diffusivity were determined for
Detection of gaseous pollutants emitted from engine powered by biodiesel and diesel mixtures
Nowadays air pollution has been regarded as a serious environmental problem. One of the main generators of air pollution is the transportation, since the gas combustion from various chemical species
