Abstract
In this study an experimental investigation has been carried out on diesel engine to understand the engine behaviour with respect to its performance and emission characteristics while using Aluminium oxide (Al2O3) Nano particle as additive with a blend of diesel and biodiesel sourced from Waste Plastic Oil (WPO). The Alumina Nano particles are characterized by X- ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) analysis, UV-Vis Spectroscopy and Zeta Potential Analysis. The alumina Nano particles are blended with Waste Plastic Oil in the mass fractions of 10 and 20 ppm using an Ultrasonicator. The experiments are carried out in single cylinder four stroke Variable Compression Ratio diesel engine by varying the load using eddy current dynamometer. The experimental results reveal that there is a significant improvement in the performance characteristics like Brake Thermal Efficiency and Brake Specific Fuel Consumption and considerable reduction in the emission constituents like carbon Monoxide (CO) and Unburned Hydrocarbon (HC) and smoke but in turn increase in Nitric oxide (NOx) emissions were observed.
