“…For instance, the improvement in BTE is achieved by more quantity of fuel to react by way of air due to the higher surface to volume proportion. 16 The BTE was decreased with increasing blends from B10 to B20. This is because of resistance flow of fuel blends are varied it slows down the combustion, atomization, and fuel vaporization.…”

This article investigates the utility of waste tyre oil as a potential source of partial replacement of diesel fuel. The experimental study of engine parameters such as performance, emissions, along with combustion characteristics of tyre oil blends with cerium oxide (CeO2) and without CeO2 nano additive in a four‐stroke single‐cylinder water‐cooled compression ignition engine was conducted without any engine adjustment. Tyre oil was blended with diesel fuel at the volumetric proportions of 5, 10, 15, and 20%. These experimental results reveal that B5 blend has increased Brake thermal efficiency compared to other blends and nearer to diesel fuel at full load. The emissions of Hydrocarbon (HC), smoke are lower than diesel fuel by 3, 3.22% for B5 blend of full load. If CeO2 nano additives are doped with tyre oil blends in such case the B5D85 + CeO2 100 ppm blends were increased in efficiency of 2.85% and emissions like HC, CO, Smoke are decreased by 3, 1.33, 7.7%, respectively compared to diesel. From the experimental results, B5D85 + CeO2 100 ppm fuel blend is the best fuel ratio for a CI engine for increased efficiency, reduced emission and better combustion. Hence, the tyre oil with CeO2 nano additives is a suitable alternative fuel for CI engine.

“…Researchers reported enhancements of combustion performance as well as emission characteristics. Possible mechanisms are catalytic processes at the nanoparticle surface as well as increased evaporation rates due to radiation absorption by the particles [83][84][85][86][87][88][89][90][91][92][93][94]. Kao et al as well as Sarkar and Hirani suggested the addition of nanoparticles to brake fluids to improve thermal transport of dissipated braking energy and increase the boiling point to avoid vapor lock [95,96].…”

h i g h l i g h t s Thermophysical properties bring nanofluids into various engineering applications. Quantity of variable parameters hinder comprehensive equations, e.g. for viscosity. Coordinated research can help to overcome debates about thermophysical properties. Missing experience for nanofluids in large scale plants. Lack of studies about high pressure/temperature applications and long term behavior. a b s t r a c tIn the roughly two decades from the first publication until today, nanofluids have found their way into various research fields. To-date published documents range from basic research to high-tech applications. This contribution aims at outlining current fields of research regarding nanofluid research. These range from fundamental property data studies presented in the first section to a listing of numerous applications of different fields of engineering. It is shown that nanofluid science pushes increasingly into the scientific world providing plenty of new questions and challenges.

“…Also, it is clear that for all concentration of ZONP there is marked increasing specially at high engine loads. As a response of adding ZONP to the diesel fuel, the BTE improvement could be attributed by the slightly higher peak cylinder pressure and faster heat release rate [24,25].…”

The nanoparticles diesel additives played a major role in enhancing diesel performance by improve its efficiency and alter the emissions of CO, NOx and HC including several hazardous air pollutions. Zinc oxide nanoparticles (ZONP) is used in diesel engines which blended with diesel by using ultra sonicator and a mechanical homogenizer to achieve good dispersing. Five concentration of ZONP are studied in this study. To demonstrate and access the enhanced performance of the nano-diesel blend a comparison of fuel consumption, brake power and engine efficiency with base diesel are made. The addition of ZONP promote combustion by increasing engine performance and reducing the emissions. To evaluate the impact of ZONP on engine performance and environment, several experiments performed on the diesel engine at 1400 rpm which is kept constant throughout the experiment with different range of loads. The results show clearly that by adding the nanoparticles, namely ZONP into the diesel fuel has significant improvement of high the brake thermal efficiency (BTE) and low Brake Specific Fuel Consumption (BSFC) as compared to diesel. Also, the average reduction in CO is 33% for high ZONP concentrations and applied high loads while average increases in CO2 is 8%, and NOx is 33% and more for high ZONP concentrations and applied high loads compared to pure diesel. Furthermore, 100% eliminated HC is observed when compared to pure diesel at different loads.
