Background Mitigation of greenhouse gas emissions from transportation sources will require implementation of a variety of strategies, including improvements in the efficiency of overall vehicle/fuel systems, such as hybrid and new high-efficiency diesel engines, and use of synthetic fuels to replace or supplement petroleum-based fuels. A particularly attractive class of synthetic fuels is oxyge...

There is an extensive worldwide search for alternate fuels that can displace fossil-based resources, yet still fit within existing infrastructure. At Argonne National Laboratory, strains of fuel have been designed that are generated by photosynthetic bacteria, eventually producing a heavy alcohol called phytol (C20H40O). Phytol’s physical and chemical properties (cetane number, heat of combusti...

The methyl esters of vegetable oils, known as biodiesel are becoming increasingly popular because of their low environmental impact and potential as a green alternative fuel for diesel engine and they would not require significant modification of existing engine hardware. Methyl ester of Pongamia (PME), Jatropha (JME) and Neem (NME) are derived through transesterification process. Experimental ...

This research focusing the performance and emission characteristics study on the application of biofuel emulsions as alternate fuel used Kirloskar AV1 Direct Injection Diesel engine. Diesel engine performance was compared using different fuels, namely Diesel, Jatropha Methyl Ester and Jatropha Methyl Ester Wood Pyrolysis Oil emulsion, by applying various loads. Emission characteristics were obs...

This paper presents the technical performance measurements of biogas premixed charge diesel dual fuelled engine. A 4-stroke research diesel engine was used for the performance analysis. The performance parameters like engine brake power, brake specific fuel consumption, volumetric efficiency and brake thermal efficiency were measured and compared with conventional diesel with different proporti...

In order to investigate the effects ethanol-diesel blends and altitude on the performance and emissions of diesel engine, the comparative experiments were carried out on the bench of turbo-charged diesel engine fueled with pure diesel (as prototype) and ethanol-diesel blends (E10, E15, E20 and E30) under different atmospheric pressures (81 kPa, 90 kPa and 100 kPa). The experimental results indi...

This paper shows the results of an investigation carried out to assess the application of different fuels produced by blending diesel fuel with methyl ester obtained from mixture of 75% (v/v) sunflower oil and 25% (v/v) used cooking oil on a Kubota agricultural indirect injection diesel engine, natural aspirated, and with a rated horsepower of 19.7 kW. Seven fuels, namely diesel fuel; 90:10, 80...

BACKGROUND Exposure to traffic-derived air pollutants, particularly diesel emissions, has been associated with adverse health effects, predominantly in individuals with pre-existing respiratory disease. Here the hypothesis that this heightened sensitivity reflects an augmentation of the transient inflammatory response previously reported in healthy adults exposed to diesel exhaust is examined. ...
