Abstract    In this, the use of gasoline combinations with ethanol and nano oxide particles has been used in gasoline-based SI EF7 engines. The mixtures are prepared in five emulsions of gasoline with 10% ethanol, gasoline with 10% ethanol and 10ppm nano Mn2O3, gasoline with 10% ethanol and 20ppm nano Mn2O3, gasoline with 10% ethanol and 10ppm nano Co3O4, gasoline with 10% ethanol and 20ppm nano Co3O4. An ultrasonic cleaner is used to obtain a homogeneous gasoline combination with ethanol and additives of nano oxides during the test. To measure the output power of the engine, the Eddy current dynamometer has been coupled to the engine and to determine the emissions, an AVL gas analyzer is used. The results indicate that ethanol addition by 10% lead to 2.6% increase in brake power (BP), but interestingly 10 ppm Mn2O3 nano-additive raise the BP to 14.38% and 20 ppm nano-additive led to 19.56% increase of BP. While the BP with 10ppm and 20ppm nano-additives of Co3O4 increased by 7.96% and 11.5% respectively. With regard to emissions, ethanol presence with nano additivesin the blend reduce CO, UHC and NOx and increase CO2. The best blend is gasoline-10%ethanol-20ppmMn2O3.

چکیده    در کار حاضر، تآثیر استفاده از نانوذرات افزودنی بر سوخت ترکیبی در موتور اشتعال جرقه­ای مورد بررسی قرار گرفته است. سوخت در پنج حالت ترکیبی ، بنزین با 10٪ اتانول، بنزین با 10٪ اتانول با ppm10 و ppm20 نانو اکسید منگنز، بنزین با 10٪ اتانول با ppm10 و ppm20 نانو اکسید کبالت تهیه و تست شده است. از حمام اولتراسونیک، دینامومتر ادی­ کارنت و آنالیزور گاز به ترتیب برای همگن کردن سوخت ترکیبی، اندازه گیری توان خروجی موتور و تعیین آلاینده­ ها استفاده شده است. نتایج نشان می دهد افزودن اتانول به میزان 10٪ منجر به افزایش ٪2/6، افزودن ppm10 و ppm20 نانوذرات اکسید منگنز به ترتیب ٪14/38 و ٪19/56 و با افزودن ppm10 و ppm20 نانو ذرات اکسید کبالت به ترتیب سبب افزایش ٪7/96 و ٪11/5 توان خروجی موتور نسب به حالت پایه شده است. با افزودن نانوذرات اکسید فلزات به سوخت ترکیبی مونواکسید کربن، هدروکربنهای نسوخته و اکسیدهای نیتروژن کاهش و دی­ اکسیدکربن افزایش می­یابد.
