Investigation of Performance & Emission Characteristics of VCR Engine. By using Bio-Diesel/Diesel blends as a fuel

      Аннотация: Increase in energy demand, stringent emission norms and depletion of oil resources have led the researchers to find alternative fuels for internal combustion engines. The rapidly increasing consumption of fossil fuel and petroleum products has been a matter of concern for the many countries which imports more crude oil. Because it causes huge foreign exchange out-go on the one hand and increasing exhaust emission on the other. Therefore it is necessary for the development of renewable energy sources. Present an experimental work is conducted to obtain the operating and emission characteristics of Undi Oil Biodiesel on Variable Compression Ratio (VCR) engine run on various blends of biodiesel, compression ratios and load conditions. From the comparison of results, it is inferred that the engine performance is improved with significant reduction in emissions for the chosen oils without any engine modification.
