Experimental Investigation on Multi Cylinder Spark Ignition Engine Fuelled With Waste Plastic Oil with Oxygenated Fuels

Abstract

Abstract: In the current day situation, emissions associated with the exhaust of automobiles resulting in global warming are a major threat to the entire world and also harmful to health. In this perspective, waste plastic solid is presently getting renewed interest. Plastics have now become indispensable materials in the modern world and application in the industrial field is continuously increasing. As substitute, non-biodegradable, and renewable fuel, waste plastic oil is getting rising attention. An experimental investigation is conducted to evaluate the emission and performance characteristics of a multi-cylinder spark ignition engine fuelled with Plastic Petrol derived from waste plastic by the process of pyrolysis. Petrol is blended with waste plastic pyrolysis oil as 10%WPPO and 85% petrol as blend-I and 20%WPPO and 75% petrol as blend-II. The performance and emission characteristics are found for both the blends and compared with the characteristics of petrol. Some amounts of oxygenated fuels viz., ethanol and methanol are added in the concentration of 5% each to the both the blends and their characteristics are compared to the blends without oxygenate fuels and sole petrol. The tests are conducted using each of the Gasoline and Plastic Petrol with oxygenated fuel additives with the engine working at variable load of 0 to 7 kg for constant speed at 1500 rpm. The differences in the measured performance from the baseline operation of the engine with petrol, blends with addition of oxygenated fuels and without addition of oxygenated fuels are compared. It resulted that, by adding additives the brake thermal efficiency of the engine improved. The CO and HC emissions are reduced but NOX and CO2 emissions are increased for all the blends when compared to petrol.
