The studies were conducted to standardize the level of constituents to obtain stable diesel-ethanol-biodiesel microemulsions prepared using anhydrous ethanol (200° proof) and aqueous ethanol of 195°, 190°, 185°, 180° and 175° proof and soybean biodiesel under wide ambient temperature range. A total of twenty blends of ethanol-diesel-biodiesel were prepared and their temperature stability in the range of 0-45 0C was studied in an interval of 50 starting from 450C. Based on full range temperature stability, four microemulsions (v/v) 2000[1:0.053:0.14], 2000[1:0.0.053:0.26], 1900[1:0.11:0.62], 1800 [1:0.25:1.54], diesel: ethanol: biodiesel were selected to study engine performance. On the basis of experimental study it was concluded that 2000[1:0.053:0.35] diesel: ethanol: biodiesel microemulsion replacing 28.75 % diesel can be used in CI engine without any need for engine modification. Istraživanja su sprovedena da bi se standardizovao nivo sastojaka u cilju dobijanja stabilnih mikroemulzija dizel-etanol-biodizel, pripremljenih upotrebom dehidriranog etanola (čistoća 200°) i hidriranog etanola čistoće 195°, 190°, 185°, 180° i 175° i biodizela od soje pri širokom opsegu ambijentalnih temperatura. Ukupno dvadeset mešavina dizel-etanol-biodizel je pripremljeno i ispitivana je njihova temperaturska stabilnost u opsegu od 0-45°C, u intervalima od po 5°, počevši od 45°C. Na osnovu punog opsega temperaturske stabilnosti izabrane su četiri mikroemulzije dizel-etanol-biodizel (v/v): 2000[1:0.053:0.14], 2000[1:0.0.053:0.26], 1900[1:0.11:0.62], 1800 [1:0.25:1.54], za ispitivanje performansi motora. Na osnovu eksperimentalnog ispitivanja zaključeno je da se mikroemulzija dizel-etanol-biodizel 2000[1:0.053:0.35] može upotrebiti kao zamena za 28.75% dizel goriva u dizel motoru bez ikakvih modifikacija na motoru.
