Abstract

In this study, production, performance and emission characteristics of methyl esters of Oleander, Kusum and Bitter Groundnut oil in a transportation diesel engine were studied. Oleander oil methyl esters (OOME), Kusum oil methyl esters (KOME) and bitter Groundnut Oil Methyl Esters (BGOME) were prepared by transesterification process. The effects of three methyl esters on engine performance and exhaust emissions were examined at different engine speed and full load condition. Experimental results showed that the brake thermal efficiency of OOME is found higher and brake specific fuel consumption lower compared to KOME and BGOME. BGOME shows less emissions compared to OOME and KOME. In short, it may be concluded from the experimental investigations that biodiesel from different non-edible oils (Oleander, Kusum, and Bitter Groundnut) can become an alternative source of fuel in future.

4. Conclusions

Biodiesels were produced by chemical transesterification and different properties of biodiesel were determined. The performance and emission characteristics were studied for a transportation engine. The biodiesels such as oleander oil (OOME), Kusum oil (KOME) and bitter Groundnut oil (BGOME) show poor performance compared to diesel fuel. The CO, HC emissions and smoke opacity of OOME, KOME and BGOME were found to be slightly less than that of diesel fuel. The NOx emissions were slightly more than that of diesel. Overall engine operation with all three biodiesels (OOME, KOME, and BGOME) was smooth. All tested biodiesels (OOME, KOME, and BGOME) exhibited reduced brake thermal efficiency and exhaust emissions (CO and HC and smoke opacity) except NOx. The engine could be operated with these biodiesels without major modifications.
