Abstract: Degradation of environment and Fossil fuel depletion are serious problems confronted now-a-days. Fossil fuels are in future will become reduced due to its excess quantity of extraction and high consumption. Hence, the use of biodiesel is considered to be a promising as they are clean are clean, renewable fuels and better substitute for the diesel in all the CI engines. In this present research work performance and emission characteristics of 10%,30% and 50% trans esterified peanut oil blended with diesel on a single cylinder,4-stroke, water cooled CI engine test RIG varying different compression ratios were analyzed and emissions HC,CO, CO2,O2 and NOx were studied with 5-gas exhaust gas analyzer. The change of compression ratios from 14 to 19. At compression ratio 19 resulted in 32.85% PB10 blend gives the maximum brake thermal efficiency and minimize bsfc 0.28 kg/kWh respectively. At different compression ratios CR 19 given the best performance and lower emissions at all load conditions. The DEE additive 5% is added to the PB50 blend. This PB50+5% blend gives the better performance and lower emissions at CR 19.
