Performance and Emission Testing of VCR Engine by using Blends of Simarouba Biodiesel with Turmeric Leaf Oil at Various Compression Ratios

In modern times, biodiesel is derived, or has been reported to be producible from many different sources, including vegetable oils, animal fats, used frying oils, etc. In the present work, Simarouba Glauca oil biodiesel blends with turmeric leaf oil and diesel were used as a fuel. Simarouba Glauca oil is made from the seeds of a Simarouba plant commonly known as Paradise tree. Dry seeds of Simarouba Glauca contains 60% to 75% oil. In turmeric plant leaves are the waste product, we can use it for extraction of oil. So the oil extracted from these waste leaves is used for the production of biodiesel. The blends are prepared with pure diesel as B12, B24 and B36 which includes 5% of turmeric leaf oil as an additive in each blend. Turmeric leaf oil improves stability of blends. The B12 contains 12% of Simarouba oil and 5% of turmeric leaf oil and remaining is pure diesel. Likewise the contents of remaining blends are varied. The test has been taken on VCR engine with compression ratios of 14, 16 and 18 by using biodiesel blends at maximum loading. Further the parameters such as brake power, brake specific fuel consumption (BSFC), brake thermal efficiency were compared with the pure diesel test on engine. Also, the effects of biodiesel blends on emissions has been studied under the present research.
