OPTIMIZATION AND ENACTMENT INVESTIGATION OF TYRE PYROLYSIS OIL AND THEIR ASSORTMENTS IN COMPRESSION-IGNITION ENGINE

Bio-diesel is one of the most promising alternatives for diesel needs. The present work has focused on the performance of tyre oil its blend with ethanol on a double cylinder, 4 stroke, naturally aspirated, direct injection, water cooled, and eddy current dynamometer kirloskar diesel engine at 1500 rpm for variable loads. Initially, tyre oil and their blends were chosen. The physical and chemical properties of tyre oil their blends were determined. In general, viscosity of neat tyre is high, which can be reduced through blending with ethanol and heating them. The performance and emission characteristics of engine are determined using tyre oil blend with ethanol. These results are compared to those of pure bio-diesel. By analyzing the graphs, it was observed that the performance characteristics are reduced and emission characteristics are increased at the rated load compared to those of bio-diesel. This is mainly due to lower calorific value, high viscosity and delayed combustion process. From the critical analysis of graphs, it can be observed that 20% of ethanol and with 80% of tyre oil is the best suited blend for diesel engine without any engine modifications. It is concluded that tyre oil can be used as an alternate to diesel.
