Thermal Performance and Exhaust Emission Analysis of Single Cylinder CI Engine with Karanja oil, Jatropha Oil Blends with Pure Diesel

Currently, alternative fuels are being investigated in detail for application in compression ignition (CI) engines resulting in exciting potential opportunities to increase energy security and reduce gas emissions. Biodiesel is one of the alternative fuels which is renewable and environmentally friendly and can be used in diesel engines with little or no modifications. The objective of this study is to investigate the effects of biodiesel types and biodiesel fraction on the emission characteristics of a CI engine. A stationary diesel engine is tested with different biodiesel-diesel blends, such as B0 (neat diesel), B10 (10 vol. % biodiesel), and B20 (20 vol. % biodiesel) for performance and emissions under different load conditions by Varying Compression ratio (VCR). Engine performance will be studied by measuring brake specific fuel consumption (bsfc) and fuel conversion efficiency (nf), Brake mean effective pressure (BMEP). The emission of carbon monoxide (CO), hydrocarbon (HC) and carbon dioxide (CO2) will be measured by using 4- way gas analyzer. This study will focus on usage of biodiesel derived from the oils of Karanja and Jatropha Blends with pure diesel.
