Experimental Investigation on Mixing of Waste Plastic and Tyre Pyrolysis Oil Blends with Diesel in a Single-Cylinder Four-Stroke Diesel Engine

Abstract

Energy consumption in the form of fossil fuels has increased continuously. Because of its lightweight, simple carrying and low price, the modern world utilizes many products with waste plastic and waste tyre as a main source. As a result of this, there is an issue of dumping plastic and tyres into areas of land due to the drastic rise in these reserves each year, municipal waste posses many environmental problems. The latest trend toward converting waste into quality fuels is waste to energy. This present article introduces the use of waste plastic pyrolysis oil and waste tyre pyrolysis oil as an alternative fuel for testing the four-stroke single-cylinder VCR water-cooled diesel engine. Performance and emissions characteristics for mixing waste plastic and waste tyre pyrolysis oil together with diesel mixtures with different blending ratios such as D100, B5-D95, B10-D90, B15-D85, B20-D80, B25-D75, and B30-D70 at a speed of 1500 rpm with loads of 2, 4, 6, 8, and 10 kg at rated brake power are investigated. Compared to diesel and all other blends, the B20-D80 blend found decent effects. For B20-D80 blend, brake thermal efficiency has increased compared to pure diesel, and brake-specific fuel consumption is reduced. With enhanced blend ratios, CO emissions were increased, NOx reduced with increase in blend ratios, and UHC emissions and smoke are decreased than diesel fuel.
