An Examination of a Diesel Engine's Performance and Emissions Using a Fuel Blend of Diesel, Biodiesel, and Diethyl Ether

Using blended fuels in conventional diesel (CI) engines has become a prominent method of reducing air pollution, lowering the intensity of dependence on conventional fossil fuels, meeting the energy requirements at a lower price etc. Due to all these advantages, numerous researches are being conducted across the globe. Fuel blends are prepared by mixing pure conventional diesel, biodiesel (prepared using waste feedstocks through transesterification process) and several fuel additives. Diethyl Ether (DEE) has come across as one of the most important fuel additives that provides rich oxygen content for proper combustion of the fuel blend. The current study focuses on the analysis of an engine powered by diesel that runs on a fuel blend consisting of diesel, biodiesel, and DEE blended in two distinct ratios. B60BD20DEE20 and B60BD25DEE15 are the names given to the blended fuels. A comparative analysis incorporating the results from performance while pure diesel is utilized in the engine has been carried out, along with performance evaluation and estimation of the emissions of a chosen diesel engine utilizing these fuel blends. Out of the two bends, blend D60BD20DEE20 is displaying the higher BTE values when we compare it to the other blends. Therefore, we can deduce that BTE increases when we raise the proportion of DEE from 15 to 20%. The smallest Brake Specific Fuel Consumption (BSFC) is found in pure diesel when the three fuels are compared. Upon comparing the blends, we find that, out of the two bends, D60BD25DEE15 exhibits the lower levels of BSFC. Therefore, it follows that BSFC rises when the quantity of DEE grows from 15 to 20%. Out of the two bends, D60BD20DEE20 exhibits the highest NOx emissions when we evaluate the mixes with one another. Therefore, it may be said that NOx emissions rise as the fraction of DEE increases from 15 to 20%. Out of the two bends, D60BD25DEE15 is exhibiting the lowest HC emissions when we evaluate the mixes with one another. Therefore, it can be said that HC emissions rise as the fraction of DEE increases from 15 to 20%. Out of two bends, D60BD25DEE15 exhibits the lowest CO emissions when we evaluate the mixes with one another. Therefore, it follows that CO emissions rise when the DEE fraction is raised from 15 to 20%. A comparison of the two methodologies has been carried out to assess the influence on BTE, BSFC, and NOx, CO, and HC emissions. The research study's findings indicate that B60BD25DEE15 is the most ideal fuel blend to utilize in place of conventional diesel.
