Performance and emissions of CI engine by using blended fuel

Increase in energy demand, stringent emissions norms and depletion of oil resources led to find alternate fuels for internal combustion engines. Many alternate fuels like alcohols, bio diesel, LPG, CNG, etc.it have been already commercialized in the transport sector. In the context, Pyrolysis of solid waste is currently fuel receiving renewed interest. The disposal of waste tyres can be simplified to some extent by pyrolysis for getting oil. This pyrolysis oil can be blended with diesel and used as an alternate fuel for CI engines. In the present work the performance characteristics and emissions are evaluated on a single cylinder 4 stroke diesel engine fuelling with 20%, 40%, 60% and 75% pyrolysis oil-diesel blends by volume. These results are compared with the results obtained when fuelled with pure diesel oil.
