Performance And Emission Analysis Of Single Cylinder 4-Stroke Diesel Engine Using Diesel, Sesame Oil,And Dimethyl Carbonate Blends

World today facing challenge of energy depletion and environmental pollution. The transport sector in India is major energy consuming sector. The dependence on fossil fuels in road transport sector is deep routed and its increasing exponentially as the number of vehicles on road is shooting up. . Many alternate fuels like Alcohols, Biodiesel, methanol, ethanol, LPG,CNG have already been commercialized in transport sector. In this context, Sesame oil is used as a blended fuel with Diesel with different concentration like 20%, 30% and 40%.The best blend was found from the analysis. It was found that the performance characteristics are decreased and emission of different gases like HC, CO, CO2 was increased. So DMC (Dimethyl carbonate) was added to improve performance and reduce emission characteristics. The DMC was added in concentration of 5%, 10% and 15%.
