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 influences of different diesel/biodiesel blends and EGR rate on brake specific fuel consumption (BSFC), exhaust gas temperature, NO, HC, CO emissions, are studied and demonstrated. In this paper a four stroke direct injection, water cooled, diesel engine was used. Biodiesel either in neat form or as a blend with diesel fuel is extensively investigated to solve the twin problem of reduction ...

This study discusses the suitability of iso-butanol/diesel fuel blends as an alternative fuel and determines their effects on the performance and combustion characteristics of a heavy-duty diesel engine. For this purpose, various isobutanol/diesel fuel blends containing 5%, 10% and 15% iso-butanol were prepared in volume basis and tested in a turbo-charged, six-cylinder direct injection diesel ...

In this study, preheated crude sunflower oil at 75C was used in a fourcylinder, naturally aspirated, indirect injection diesel engine. The experiments were conducted at the constant engine speeds under the full load condition of the engine to determine the performance, combustion, and injection characteristics of test fuels. The engine test results have been compared with the reference values t...

A single zone C.I engine model has been developed in an in-house code that would be suitable for conventional diesel as well as for alternative fuel (biodiesels), to predict the pressure and temperature variation along crank angle, work done, mean effective pressure, power output and other engine parameters suitable for biodiesel. The model has been validated with the experimental results. Perf...

The transport systems are dependent on the fossil fuels especially liquid fuels and these fuels are depleting at much faster rate than production. The consumption of fossil fuels is very unstable and directly affects the economy of our country as we are importing it from other nations so this factor has urged us to find other alternatives to prolong the usage of petroleum. Thus, by using bio-fu...

The phase stability of DE and DBE blends at different component concentrations, as well as the effects of using DBE blends including ethanol of various proportions on a CI engine performance are experimentally investigated. The engine was operated with DBE blends having 5, 10, 15 and 20% ethanol with fixed 10% biodiesel on a volume basis, to solve the phase separation problem, as well as on die...
