Investigation of CI engine performance and emission characteristics by DME fumigation at rate of 100 gm/hr & 150gm/hr by using tyre pyrolysis oil as fuel in CI engine

Abstract

This work investigated engine performance and emissions using waste tire oil-diesel-biodiesel blends. A sustainable fuel glycine max biodiesel was blended with the tire oil-diesel blends to improve performance, combustion, and exhaust emissions.The present study was conducted with the main objective of improving the performance, emission, and combustion characteristics of a direct injection diesel engine fuelled with methyl ester biodiesel by DME fumigates at 100gm/hrand150gm/hr flow rates. The effects of DME fumigation (the addition of DME to the intake air manifold) and tyre pyrolysis oil biofuel blends on the performance and emissions of a single-cylinder diesel engine were compared in a study. An attempt was made to determine the optimum percentage of DME that gives lower emissions and better performance. All fuel blends showed similar properties to diesel. With similar engine performance, like torque, power, efficiency, energy, and exergy metrics, the blends showed insignificant variations in emissions (carbon dioxide, nitrogen oxide) compared to a reference diesel fuel. Interestingly, the experimental results were compared with the modelling results. The outcome of this research can promote waste tire pyrolysis oil as an alternative fuel for diesel engines and accords with alternative energy development initiatives all over the world.
The study's main goal is to assess the credibility of tyre pyrolysis oil as an alternative fuel and to determine the minimum specific fuel consumption for the various parameters in an internal combustion engine in order to save millions of tonnes of fuel. ns  of fuel. The literature survey reveals that a little research has been conduct to obtain  the optimal levels of variable parameters that yield the optimum SFC in Compression  Ignition (CI) engine.
