Development of Diesel-Ethanol Engine for HCV 2019-26-0089

Diesel engines dominate in Heavy-Duty applications due to its better fuel economy, higher durability and larger reliability. Fuels derived from petroleum resources are depleting daily and it's become a scarce resource for future generation to come. With growing environmental awareness about the negative implications brought by excessive usage of fossil fuels, the race of finding alternative fuels as their substitution is getting heated up. At present, renewable energy from bio-fuels has been touted as one of the most promising substitution for petroleum derived diesel. Using bio-ethanol blended diesel fuel for automobile can significantly reduce diesel usage and exhaust greenhouse gases. Bio-ethanol can be produced by alcoholic fermentation of sucrose or simple sugars. The main drawback is that ethanol is immiscible with diesel fuel over a wide range of temperatures, and the hygroscopic nature of ethanol leading to phase separation in blend. In present study diesel-ethanol blends commonly known as E-diesel are prepared with different Ethanol proportion such as 5%, 7.7%, 10%, 12.5% & 15%. The effect of each blend is studied for engine performance & emissions. The method for diesel-ethanol blend preparation with different additives to improve the stability, lubricity and combustion efficiency is established. The optimized E-diesel blend is further tested for engine durability to find out the long term effect on the engine performance with such kind of new upcoming cross blended fuel.
