Today, world’s energy needs are met all the way through fossil fuels and natural gas. As an outcome, the amount of fossil fuel is diminishing from year to year. This article shows the prospect of coconut oil as a renewable and alternative fuel for diesel. The diesel engine has versatile uses in small power generation and automobile sectors. This article is mainly focused on the performance and emission strategy while using biofuel as a substitute in diesel engine. An experimental arrangement is used to study the performance of a small diesel engine using different blends of biodiesel converted from coconut oil. With biodiesel, the engine is proficient running without difficulty. Different blends of biodiesel (i.e. B75, B50, and B25) have been used to avoid problematical modification of the engine or the fuel supply system. In conclusion, a comparison of engine performance for different blends of biodiesel has been accepted to determine the best possible blend for different operating conditions. As per the case study, coconut oil–diesel fuel blend resulted in lower smoke and NOx emissions. Besides, this research mainly focuses that the concentrations of biofuel increase the emissions of carbonyl compounds and that of acetaldehyde when compared with results from sole fuel (diesel) with same engine. Possible impacts of changing diesel to B75 diesel indicate an increase of ozone formation. In terms of environment health, a lower impact was projected considering only the changes in biofuel concentrations. |
