ABSTRACT Tests have been carried out to evaluate the performance, emission, and combustion characteristics of a single cylinder direct injection diesel engine fueled with 10%, 30%, and 50% of tyre pyrolysis oil (TPO) blended with diesel fuel (DF). The TPO was derived from waste automobile tyres through vacuum pyrolysis. The combustion parameters such as heat release rate, cylinder peak pressure, and maximum rate of pressure rise also analysed. Results showed that the brake thermal efficiency of the engine fueled with TPO-DF blends increased with an increase in blend concentration and reduction of DF concentration. NO(x), HC, CO, and smoke emissions were found to be higher at higher loads due to the high aromatic content and longer ignition delay. The cylinder peak pressure increased from 71 bars to 74 bars. The ignition delays were longer than with DF. It is concluded that it is possible to use tyre pyrolysis oil in diesel engines as an alternate fuel in the future.

    ABSTRACT: Current energy and environmental situations have been driving the development of new alternative energies, especially in transportation sector. The objective of this research is to present a decision support methodology to compare engine torques between using the average value and the new approach called response surface. This research investigates the engine torques from neat diesel fuel (WPO (waste plastic pyrolysis oil) 0%) and blend 25% of waste plastic pyrolysis oil by volume in diesel (WPO 25%) at wide range of engine load (20%, 40%, 60%, and 100%) and speed (800 rpm, 1200 rpm, 1500 rpm, 1800 rpm, and 2000 rpm). A heavy-duty multi-cylinder diesel engine was installed on an engine dynamometer and the torque data were recorded. The contribution of this research is to present a more accurate methodology to perform an engine torque comparison. The value of this research lies in the development of a new approach, which is applicable to decision makers in obtaining an engine torque comparison. Consequently, the benefit of the research is that the empirical data from a heavy-duty diesel engine fueled with waste plastic oil blends are revealed. The number of experimentations can be reduced and this leads to lower costs and less time usage for future research.

    ABSTRACT: This paper presents the essential features of an efficient and environmentally attractive pyrolysis for used tyres valorisation with energy and material recovery. The problem of tyres management strongly affects not only the environmental protection but even the resources maintenance, since problems related to the depletion of resources, energy demand and waste management, are strictly connected and required an integrated approach. A general guideline for EU member states, aims to reach a zero post-consumer amount of tyre disposal in landfills before the end of 21st century, to optimize and expand the already well studied ways of their treatment and find new ones, in order to accomplish a balance between economy and environmental protection. In this context, thermal treatment of end of life tyres could play a relevant role for the recovery of resources (matter and/or energy). During the past 10-15 years, several fundamental and applied studies showed that if carefully controlled, tyre pyrolysis can produce a number of valuable products. The final destination of the pyrolysis solid residue largely influences the industrial applications of pyrolysis.

    ABSTRACT: Keywords: Renewable Licella biofuel Thermal and mechanical efficiency NO PM emissions a b s t r a c t The current study investigates the opportunity of using Licella biofuel as a partly renewable fuel provided by Licella P/L. Hereafter this fuel will be referred to as Licella biofuel. The renewable component of the Licella biofuel was made from the hydrothermal conversion of Australian pinus radiata wood flour using Licella's proprietary Cat-HTR™ technology. The diesel-soluble component of the hydrothermal product was extracted into road diesel to give a blended fuel containing approximately 30% renewable material with the balance from diesel. This was further blended with a regular diesel fuel (designated R0) to give fuels for testing containing 5%, 10% and 20% renewable fuel (designated R5, R10 and R20). Some of the key fuel properties were measured for R30 and compared with those of regular diesel fuel. The engine experiment was conducted on a four-cylinder turbocharged common rail direct injection diesel engine. All experiments were performed with a constant speed and five different engine loads. Exhaust emissions including particulate matter (PM) mass and numbers, nitric oxide (NO), total unburnt hydrocarbon (THC), carbon dioxide (CO 2) and performance parameters including brake power (BP), indicated power (IP), brake mean effective pressure (BMEP), indicated mean effective pressure (IMEP), mechanical efficiency (ME), brake thermal efficiency (BTE) and brake specific energy consumption (BSEC) were investigated for all four blends (R0, R5, R10 and R20). Among other engine parameters, in-cylinder pressure , heat release rate (HRR) and pressure (P) versus volume (V) diagrams were also investigated for the four fuel blends.
