Simulation of the Performance and Emission Analysis of Diesel Blend Biofuel Obtained From Cold Pressed Hemp Seed Oil with and without Suitable Nano Additives

According to the test on a typical modern Euro 6 diesel engine conducted by the International Council on Clean Transportation (ICCT), it was found that it emits 7 to 10 times more Nitrogen Dioxide than the achieved Euro 6 Test Limits (80mg/ km). In 2018, a total of 24% of global CO2 emissions from fuel combustion came from transportation. This truly calls for the need for a lesser polluting alternative fuel in the automotive industry. After being inspired by the work done by researchers all across the globe on biodiesel, we propose the idea of synthesizing biofuels from cold-pressed hemp methyl ester. First, we conducted alkaline transesterification to produce hemp methyl ester from the cold-pressed hemp seed oil. Based on the Gas Chromatography-Mass Spectrometry (GCMS) analysis report of the hemp methyl ester from the literature, we found out the physical and chemical properties of it using BioDiesel Analyzer software. We compared the physical and chemical properties of the hemp methyl ester with diesel as per the ASTM standard D975 for diesel. We conducted the Diesel RK simulation of the performance and emission parameters of a Compression Ignition(CI) Engine test rig using diesel, pure hemp methyl ester, and diesel blended with hemp methyl ester in the ratio 80:20 by volume(B20). The performance and emission parameters obtained from the Diesel RK software are compared with that of standard diesel emissions. If higher emissions of any of the greenhouse gases are reported from the Diesel RK simulation, a suitable nano additive is proposed after an extensive critical analysis.
