Enhancing the Performance & Emission for the Blend of Diesel & Pyrolysis oil of Tyre

Increase in energy demand, stringent emission norms and depletion of oil resources led the researchers to find alternative fuels for internal combustion engines. Many alternate fuels like Alcohols, Biodiesel, LPG, CNG etc. have been already commercialized in the transport sector. In this context, pyrolysis of solid waste is currently receiving renewed interest. The disposal of waste tyres can be simplified to some extent by pyrolysis. The properties of the Tyre pyrolysis oil derived from waste automobile tyres were analysed and compared with the petroleum products and found that it can also be used as a fuel for compression ignition engine. In the present work, blends of Diesel-Tyre pyrolysis oil was used in a diesel engine without any engine modification. The entire work is concentrated to enhance the performance and emission parameters of C.I. engine for the blend of Diesel and pyrolysis oil of tyre. To enhance the performance the effect of supercharging was used. The experiment is carried out on C.I. engine using pure diesel and various blends such as TPO10, TPO20 and TPO30 at normal atmospheric pressure and at different supercharged pressures 1.2 bar, 1.4 bar and 1.6 bar and results were compared. It is observed from the results that at supercharged pressures 1.2 bar and 1.4 bar, the performance parameters like brake thermal efficiency and brake specific fuel consumption and emission parameters like emission of CO and HC have been improved. But the emission of NOx was not improved as there is rise in peak temperatures of combustion due to supercharging the emission of NOx increases.
