TL;DR: In this paper, the transesterification process for production of rice bran oil methyl ester has been investigated, and the various process variables like temperature, catalyst concentration, amount of methanol and reaction time were optimized with the objective of producing high quality rice brans oil biodiesel with maximum yield.

TL;DR: In this article, a two-cylinder, air-cooled, constant speed direct injection diesel engine was used for experiments to investigate the usage of biodiesel and exhaust gas recirculation (EGR) simultaneously in order to reduce the emissions of all regulated pollutants from diesel engines.

TL;DR: In diesel engines, NOx formation is a highly temperature-dependent phenomenon and takes place when the temperature in the combustion chamber exceeds 2000 K as mentioned in this paper, therefore, in order to reduce NOx emissions in the exhaust, it is necessary to keep peak combustion temperatures under control.

TL;DR: In this article, the use of heterogeneous catalyst (CaO) for the production of Jatropha biodiesel through transesterification reaction was discussed and the RSM model was evaluated and found to be adequate as the regression coefficient R2, Adj. R2 and Pred. R 2 were found to have been satisfactory.

TL;DR: In this paper, the use of vegetable oil derivatives to substitute mineral diesel fuel was investigated and the results showed that biodiesel can be used as partial substitute fuel in existing diesel engines without substantial hardware modification and it significantly lower the emissions of harmful species from diesel engines, without jeopardizing the engine performance.
