Processing of Waste Tyre Material Pyrolytic Oil Blends with Diesel Fuel in a Diesel Engine for the Investigation of its Performance Characteristics

Abstract

Increase in energy requirements, strict emission norms and exhaustion of fuel resources enforces us to switch towards some renewable sources of energy. Since the availability of fossil fuels is not enough to meets all the energy requirements of present and future livelihoods. Waste Tyres Derived (WTD) can be one of the alternate source to recover energy, since it is having all the characteristics to run a diesel engine smoothly. In this study, experimental investigation have been performed to estimate the performance and combustion parameters of a dual cylinder, water cooled, direct injection diesel engine by using diesel fuel with 5%, 10% and 15% by weight contributions of Tyre Pyrolysis Oil called as DTPO5, DTPO10 and DTPO15 respectively. Raw DTPO contains huge amount of carbon therefore Vacuum Distillation is performed before blending it with diesel fuel. Several performance parameters like Brake Power (BP), Indicated Power (IP), Brake Thermal Efficiency (BTE), Mechanical Efficiency (ME), Indicated Mean Effective Pressure (PIME) etc. are analysed thoroughly by keeping loads of 2kg, 4kg, 6kg and 8kg on the diesel engine. The results are shown that at 0kg load the BTE is maximum for DTPO15 having value 35.25%, while at 8kg load the BTE is maximum for pure diesel having value 38.71%. Among the blending mixtures the maximum value of ME is shown by DTPO15 at 8kg load having value 19.19%. The maximum value of Indicated Mean Effective Pressure is shown by DTPO15 at 6kg load having value 15.56 bar. Finally, it is concluded that the tyre pyrolysis oil is possible to run a diesel engine and it can be an alternate fuel to meets the energy demands globally.
