A four-stroke water cooled direct injection (DI) diesel engine with cooled EGR system was used in this work. The diesel engine was fueled by diesel fuel, jatropha oil and low (LPM) or high (HPM) purity methanol blends at the ratio of 100/0/0, 75/20/5, 70/20/10 and 65/20/15% on volume basis respectively for the variation of engine loads in the range of 25 to 100% with 25% increments at 2000 rpm. Each load for every fuel blend was given by the 0% and 16.5% EGR rates. The results are found that the brake power for diesel engine fueled by diesel fuel, jatropha oil and LPM is approximately 8% lower than that of diesel engine fueled with the neat diesel, while it increases to 5.24% at the low load and reduces to 6.11% at the high load by injecting HPM in the fuel blends. At the same case, BSFC increases approximately 4.5% by injecting LPM in the fuel blends. The brake thermal efficiency rises approximately by 3.3% with LPM in the fuel blends, whereas it increases approximately 6% by injecting HPM. The smoke opacity reduces approximately by 70% with LPM or HPM in the fuel blends.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Brake thermal efficiency,Cooled EGR,Direct injection diesel engines,Fuel blends,High purity,Jatropha oil,Smoke Emission,Smoke opacity[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Cooled EGR,Diesel engine,Fuel blends,Low and high purity methanol,Performance and smoke emission[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.4028/www.scientific.net/AMM.660.426[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
