Published by Elsevier Ltd.The use of bioethanol as supplementary fuel for diesel engine has widely been used and result a positive effect. This paper shows the performance map of indirect diesel engine fuelled with diesel bioethanol emulsion. Experiment was carried out on two cylinders indirect diesel engine were coupled to eddy current dynamometer. The engine is loaded by the dynamometer, fuel consumption by AVL fuel balance, air consumption by TGS hot wire anemometer, emission analyzer by Horiba Mexa 720 and Sukyoung SY-GA 401, while Okudakoki DSM 240 for smoke level. The experiment is focused on specific fuel consumption (BSFC) and its emissions such as; nitrogen oxides (NOX), carbon monoxide (CO), and the concentration of the exhaust gas (smoke). Test is conducteded on 1500 rpm, 1750 rpm and 2000 rpm with gradual load for every 10 Nm from 0 Nm up to 70 Nm. Various percentages of bioethanol in diesel is tested, start from neat diesel fuel (DE0), diesel fuel with 2.5% bioethanol (DE2.5), diesel duel with 5% of bioethanol (DE5) and DE10 for diesel fuel with 10% of bioethanol with 1% of emulsifier are added. Performance maps are created using software Uniplot. At 83% full load (10.81 kW), the BSFC is reduced up to 2.62% at 1987 rpm on DE10 mixture, while at low rotation (1481 rpm) DE2.5 mixture will increase fuel consumption up to 4.51% compared to neat diesel (DE0). The result of NOX emissions is inconsistent, but the trends are increasing. Trends for CO emission are reduced, maximum reduction up to 71.43% at DE10 and 1987 rpm. The exhaust gas concentration tends to decrease, maximum reduction up to 65.87% on DE10 mixture, 1734 rpm and 83% full load operation. The addition of bioethanol up to 10% is tends to improve the combustion process at high speed.[/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]Combustion pro-cess,Diesel,Eddy current dynamometer,Emulsifier,Hot wire anemometers,Performance,Performance characteristics,Specific fuel consumption[/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]Bioethanol,Diesel,Emulsifier,Mapping,Performance[/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]This project is financially supported by Indonesian Institute of Sciences – Research Centre for Electrical Power and Mechatronics through the Kompetitif LIPI 2011/2012 research project.
