Investigation on the effects of nano particles infused biodiesel and turpentine oil powered low heat rejection diesel engine

Abstract

Energy resources are the magnificent reason that keeps the dynamism of the world at its full swing. Without energy, any kind of literal movement upon the planet will be at stake. However, the reckless exploitation of fossil fuels and non-renewable energy sources has led to environmental degradation and depletion of resources. Thus, the world is now facing energy crisis, which has duel requisite: one is the need for alternative source of energy and the second is that it must be environmentally degradable i.e., it must be a safer fuel. In the present investigation, the performance parameters, emission levels and combustion characteristics of D.I. diesel engine were examined with biodiesel extracted from mango seed oil. Initially, mango seed biodiesel was blended with standard diesel. Secondly, 10% of turpentine oil was added with partial engine modification. Finally, nano particles were infused with the test fuels and the obtained results were investigated and analyzed carefully. In pre-phase of stage -1 work, the soxhlet mechanical oil extraction method was adopted to extract mango seed oil from the mango seeds. Then it was converted as mango seed biodiesel through transesterification method. Thus obtained biodiesel was mixed in different proportions with the standard diesel fuel on volume basis to obtain MSBD15, MSBD25, MSBD50, MSBD75, and MSBD100. In the first stage of this research work, the different proportions of biodiesel blends were used on a volume basis. The result inferences at full load conditions clearly showed that BSFC increased with respect to increase in biodiesel proportion. And also, BTE reduced by 0.8% to 7.71%, 5.1% to 18.28% higher NOx, 5.7% to 18.28% lesser UBHC and 8.05% to 43.65 % lower smoke as compared to standard DF. The CO emission reduction ranges ii from 5.0% to 19.23% for the blends MSBD15, MSBD25, MSBD50, MSBD75 except MSBD100. At full load conditions, CO emission followed decreasing trend for all MSBD blends except MSBD100. The analysis showed MSBD15 and MSBD25 are having closer
