“…[1] Pyrolysis is another approach to convert carbohydrates and even plastics into bio-oil that can be converted into biodiesel [2] or co-fired directly with diesel in a diesel engine. [3] Other methods investigated included a microemulsion of alcohol with vegetable oil that can perform nearly as well as diesel fuels. [1] However, the dominant and well established method for commercial biodiesel production in the last two decades is transesterification.…”

“…The EGR performance is investigated with higher smoke level, particulate and the hydrocarbon emissions for 5% TPO. Sharma and Murugan [17] investigated the response of changing the compression ratio for optimal injection time and pressure on the performance of a CI engine and its mixture with TPO at peak value of compression ratio. The lower CO, HC and smoke emissions are obtained as compared at lower CR at peak load.…”

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.

“…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.
