“…Their analysis implied that the oil obtained can be used as a fuel after proper treatment. Recently Vihar, et al [21] utilized TPO in a latest turbocharged 4-cylinder CI engine. According to their investigation, cetane improving components and higher CR is required for the use of TPO in CI engines or addition of pilot injection is required, but limited to medium to higher loading condition.…”

The need of the substitute fuels in compression ignition engines has been the major requisite of the today's world. Due to progressive diminution in crude oil and their subsequent environmental effects many researchers are working on various alternative fuels like biodiesel, methanol, alcohols, CNG, LPG, biogas. Fulfillment of the stringent emission norms is also a great concern as the fuel suggested should also offer the desired performance and should be economically and environmentally proven. Hence the oil extracted from the waste tyre is the biggest emanating fuel tested for its behavioral analysis when blended with diesel on single cylinder Variable compression ratio diesel engine. Trials are conducted with 100% diesel and then 10%, 25%, 35%, 50%, 60%, 75% and 90% TPO (tyre pyrolysis oil) blends with diesel with varying the load. It is observed that the various performance indicators like BP, IP and BMEP are boosted with rise in the proportion of TPO in the fuel oil for all loads. Increase in the BTE is found highest for moderate load up to 2.6 kg and maximum for TPO 90. Mechanical efficiency found to be maximum at TPO 35 at higher load. Lower specific fuel consumption obtained for TPO10 blend at low load and maximum at TPO 60. From the emission analysis it is found that CO emission tends to reduce up to moderate load, but increases consistently further with the load. HC emission found to be decreased with increase in TPO proportions with minimum for TPO 90 at all loading conditions. CO 2 emission gradually increased with progressive rise in the load and increases rapidly for higher loads. NO x emission and smoke increased gradually with increase in the TPO proportion. Analyzing the performance of TPO for different proportions with diesel, TPO 90 is the better alternative to enhanced output and efficiency. Whereas for lower fuel consumption and emissions TPO 10 be recommended. Again it is also seen that moderate proportion of TPO (TPO35) gives highest cylinder pressure and reduction in the fragrant sulfur.

“…Diesel engine Experiments were conducted with blends of JME-TPO, in a single-cylinder diesel engine at the advanced (24.5°CA bTDC), standard (23°CA bTDC), and retarded IT (21.5°CA bTDC) and were compared with diesel fuel and also with JME operation Wang et al [17] TPO Diesel engine TPO produced at temperatures of 350, 400 and 450 °C was used in a diesel engine, for which they were mixed with diesel, obtaining the following mixtures: 10% TPO with 90% diesel and 20% TPO with 80% diesel, and lastly, it was compared with standard diesel Pilusa [18] TPO Diesel engine The behavior of TPO previously modified by fractional distillation, which includes desulfurization, adsorption, filtration and chemical modification. This fuel was used and tested on a six-cylinder truck engine Hürdoğan et al [19] TPO and diesel Diesel engine TPO was mixed with diesel adding 10, 20 and 50% TPO to then analyze the performance and emissions generated in an internal combustion engine Vihar et al [20] TPO Diesel engine In a four-cylinder engine, the use of TPO was tested for different rates of exhaust gas recirculation and different injection parameters in order to evaluate its impact on the combustion process and the formation of emissions Sharma and Murugan [21] TPO and biodiesel (JME) Diesel engine 20%, 40%, 60% by volume of TPO were mixed with JME (biodiesel) to test the antioxidant effects on biodiesel and to evaluate its effects on engine performance disposal, one which is the extended producer responsibility in which manufacturers are responsible for a correct disposal of waste generated at the end of their product use, which has been used in the case of Brazil for some time.…”

“…In the scientific literature, there are some published works on the combustion of TPO and blends with fossil diesel and biodiesel in internal combustion engines, and in all cases, the study and design of the atomizers were not approached [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. Regarding the amount of sulfur present in the TPO, even though it presents similar amounts to other fossil fuels [3,5], this content is higher than diesel, so in some cases the TPO desulfurization procedures are used [4,5,7,18].…”

This manuscript aims to study the atomization and characterization of tire pyrolysis oil (TPO); thus, Y-Jet atomizers have been designed and manufactured by using an experimental bench, which was specifically built for such a purpose. The droplet size was measured experimentally and compared with the theoretical value obtained with the equation proposed by Wigg. The potential for production of TPO in Brazil from tires discarded for 2016 was approximately 190 million liters and in the world for the same year was 4160 million liters; these values represent an excellent alternative for the energetic use of these oils as well as a good way to valorize the by-products obtained from tire pyrolysis such as char and tire gas. The TPO can be used in combustion processes in pure form or mixed with other renewable or non-renewable fuels, so it is important to study atomization processes that guarantee an excellent quality of combustion. The spray quality generated by atomizing pure TPO and in blends (TPO-diesel) has been quantified by droplet size measurement through the Spraytec Malvern 2007 laser diffraction system, whose main properties have also been measured, such as density, viscosity and surface tension of pure liquid fuels and blends, liquid and gas flow pressure at the atomizer nozzle, and droplet size distributions generated by the atomized jet for different gas/liquid ratio values. The influence of the point where liquid pressure exceeds gas pressure at the atomizer nozzle, as well as the TPO percentage effect on droplet size, is demonstrated, and a comparison of experimental droplet size with the one which had been theoretically calculated by Wigg's equation is made. The study of the atomization of TPO, pure and blends, allows to know a favorable condition for its burning and provides a suitable destination for discarded tires. For a better characterization of the spray, the atomization cone angle was also measured for all the mixtures.

“…The results of the simulations were consistent with the experimental ones, showing deviations below 5%. Vihar et al [93] investigated the possibility to use pyrolysis oil produced from waste tires in an automotive Diesel engine. The authors aim to further extend the operating range towards lower loads by implementing a novel arrangement based on the exhaust gas recirculation and tailored main injection strategy.…”

EU energy policy is more and more promoting a resilient, efficient and sustainable energy system. Several agreements have been signed in the last few months that set ambitious goals in terms of energy efficiency and emission reductions and to reduce the energy consumption in buildings. These actions are expected to fulfill the goals negotiated at the Paris Agreement in 2015. The successful development of this ambitious energy policy needs to be supported by scientific knowledge: a huge effort must be made in order to develop more efficient energy conversion technologies based both on renewables and fossil fuels. Similarly, researchers are also expected to work on the integration of conventional and novel systems, also taking into account the needs for the management of the novel energy systems in terms of energy storage and devices management. Therefore, a multi-disciplinary approach is required in order to achieve these goals. To ensure that the scientists belonging to the different disciplines are aware of the scientific progress in the other research areas, specific Conferences are periodically organized. One of the most popular conferences in this area is the Sustainable Development of Energy, Water and Environment Systems (SDEWES) Series Conference. The 12th Sustainable Development of Energy, Water and Environment Systems Conference was recently held in Dubrovnik, Croatia. The present Special Issue of Energies, specifically dedicated to the 12th SDEWES Conference, is focused on five main fields: energy policy and energy efficiency in smart energy systems, polygeneration and district heating, advanced combustion techniques and fuels, biomass and building efficiency.
