Performance analysis of plastic oil blend by changing the fuel injection timing in diesel engine. (2021) - Boopathi, R.
Abstract: The aim of this project is to cut back the quantity of waste plastic drop into the landfills. The conversion of water plastic into fuel by using vacuum chamber (Pyrolysis) is eco-friendly for an environment which minimizes the release of toxins to the atmosphere. The plastic oil which is separated from thermoplastics, for example, polyethylene polypropylene and polystyrene. In this experimental investigation, we are changing the fuel injection timing by inserting shims into the engine it tends to Retard fuel injection timing while removing the shims is tends to Advance fuel injection timing. The behaviour of injection of fuel timing within the engine is to enhance the performance and cut back the discharge of emission to the surroundings. In Advance fuel injection timing, we observe that the BSF (Break specific fuel) consumption and NOx emission are reduces and smoke emission should be a minimum. In Retard fuel injection timing has been intentional to mitigate NOx emission and its output performance should be considerable increases. It is discovered that diesel engine with single cylinder can operate on diesel blend, with plastic oil by varying various proportions such as P10D90 (10% of plastic oil and 90% of diesel) and P20D80 (20% of plastic oil and 80% Diesel) also modifying the fuel injection timing. However, it is found that P10D90 fuel and modified advance fuel injection timing (24°) shows similar results as compared with diesel.
