Optimisation of performance and emission parameters of diesel engine using tyre pyrolysis oil

In this paper the effect of incremental rise of tyre pyrolysis oil in the blend is analyzed to explore the performance and emission parameters of a single cylinder VCR diesel engine. During experimentation proportion of TPO were 10, 25, 35, 50, 60, 75 and 90 % with diesel fuel. Tests were conducted using four different loading conditions. The experiments were performed using an analytical tool known as Design of Experiments on the basis of Response Surface Methodology. The conclusive models of the RSM prepared to predict the response criterion such as BSFC, BTE, CO, nitrogen oxides, smoke and Mechanical efficiency. The results depicted that with rise in the load, BSFC decrease while it increases with rise in TPO proportion and found lower at 50% TPO and increases again above 50% TPO. BTE increased with increase in the load and found to be highest at higher TPO. For all blends, an increase in Nitrogen oxides found with increase in load and TPO proportion. Parameter optimization executed using the desirability approach method of the RSM for improved conduct and reduced emissions. A load of 4.57 kg (61.7567%) and 40.94% TPO in the blend are suggested as the optimal criterion for the test engine.
