Emission evaluation on distilled oil of pyrolyzed waste tyre oil with nano pyrogallol fuelled DICI engine

Waste disposal is not only the process of destroying them but also the maximum possible use of them in a productive way. The tyre wastes are enormously increased with day-by-day automobile vehicle usage. These tyre wastes are used to produce the oil by pyrolysis. To improve the quality of this fuel is increased by the distillation process. The use of this pyrolysis oil and distilled oil in the CI engine has higher emissions than the diesel. Therefore, this oil is blended with diesel in a 2:8 ratio by volume. Then the nano pyrogallol (500 and 1000 ppm) is used as antioxidants in the blend to improve the engine consequences in different loads. The higher amount (1000 ppm) of the pyrogallol used blend produced a 4.11% increase in the brake thermal efficiency, 12.22% lesser NOx, 15.02% lesser smoke, 11.69% lesser HC, 22.83% increased CO emission than diesel at full load because of the improved combustion with catalytic reaction created by the pyrogallol in the combustion. Therefore, this nanofuel is suggested for use as the alternate fuel for the CI engine with lesser emission except CO.
