This paper presents a pre-mixed combustion model for diesel and Jatropha oil blends combustion studies. Jatropha oil blends are considered as a mixture of diesel and Jatropha oil. CFD package, FLUENT 6.3 is used for modeling the complex combustion phenomenon in compression ignition engine. The experiments are carried out on a single cylinder, four strokes, water cooled direct injection compress...

ISSN 2277-5056 | © 2013 Bonfring Abstract--Increasing the fuel demand brings us to find out the various alternative solutions. Out of the various research activities, bio-diesel from various oil seeds is the major activity, which decides the future energy sources. Our previous researchers concluded that Jatropha oil is to be an alternate fuel for Compression ignition (C.I) engines and it has cl...

The emission characteristics of methyl ester of refined rice bran oil – diesel blend mixed in the proportion of 10:90, 20:80, 30:70, 50:50 and 10:0 (v/v) were studied. The emission of carbon monoxide, unburnt hydrocarbons, nitric oxide and nitrogen di oxide by different fuels at various load on 3.73 kW C.I. engine were compared with respect to diesel. The emission of carbon monoxide from the en...

Oil contaminated soil, sea water and sediment samples were collected from old oil jetty of Paradip port, Orissa. These samples were screened for bacterial oil degradation using 0.5% diesel in Bushnell-Hass Mineral Salt medium. Samples were incubated separately in shaking orbital incubator at 37 0 C at 125rpm up to 15days. The level of petroleum hydrocarbon degradation was determined by gravimet...

HREE DIFFERENT newly isolated marine fungi were subjected ........to 18S rRNA gene partial sequence analysis. The resulting sequences showed that the isolates belong to Fusarium solani, Trichoderma viride and Aspergillus niger. The isolates have the ability to utilize some petroleum hydrocarbons such as hexane, motor oil and diesel oil. The tested fungi could grow up to 7 days, especially on me...

This research work depends on enhancing the execution of the diesel engine when they utilized bio diesel oil as an optional fuel without real alteration of engine design. It is also required to grow non edible feed stocks in the waste or marginal land of Gujarat. Work goal is to recognize best suitable Bio-Diesel mix by keeping numerous parameters on it. Bio-Diesel mixes will be given credit sc...

Energy conservation is important for most of the developing countries, including rest of the world. The rapid depletion in world petroleum reserves and uncertainty in petroleum supply due to political and economical reasons, as well as the sharp escalations in the petroleum prices have stimulated the search for alternatives to petroleum fuels. The situation is very grave in developing countries...

Oil spills are the significant sources of hydrocarbons entering in the receiving aquatic environment. An efficient method to remove hydrocarbons from water resources is adsorption. In this study, water soluble N,O-carboxymethyl chitosan (NO-CS) was synthesized by carboxymethylation of chitosan in a hydro-alcoholic medium at 50°C by chloroacetic acid. The polymer was characterized through degree...

Biodiesel is emerging as a promising substitute of an alternative fuel and has gained significant attention due to the predicted depletion of conventional fuels availability in near future and environmental pollution concern. Utilization of biodiesel produced from Jatropha oil by transesterification process is one of the most promising options to replace conventional fossil diesel fuel. The phy...

This paper presents a brief review on the current status of biodiesel production and its performance and emission characteristics as compression ignition engine fuel. This study is based on the reports on biodiesel fuel published in the current literature by different researchers. Biodiesel can be produced from crude vegetable oil, non-edible oil, waste frying oil, animal tallow and also from a...
