The work focuses on studying the solubility and stability of dissolved bioethanol as a fuel additive in different fuel blends of gasoline, diesel, 50% diesel/50% biodiesel. Dissolved ethanol fuel appears as particles with a unique size distribution inside the whole fuel blends, and its stability was measured in this work. Bioethanol dissolved fuel particles stability was improved after blending the bioethanol with 50% diesel/50% biodiesel than pure diesel or pure gasoline fuel alone. The obtained results reveal that the lowest bioethanol particles stability was obtained when commixed with gasoline and the suspended ethanol particles completely accumulated at different concentrations of bioethanol in the fuel blends of 2%, 4%, 6%, 8%, 10%, and 12% by volume after 1 h of mixing time. Furthermore, the measured data of the bioethanol particles size distribution reveals that the suspended stability in the diesel blend improve slightly for all bioethanol concentrations of 10%, 15%, 20%, 25%, and 30% by volume. While the bioethanol concentrations of 5% show acceptable particles stability and size distribution during the whole experiments time. Obtained results show that bioethanol suspended particles stability was enhanced for 50% diesel/50% biodiesel blend with different bioethanol concentrations of 5%, 10%, 15%, 20%, 25%, and 30% by volume basis. However, the size of the particles increased as the bioethanol concentration rose with the passage of time.

Recently the world has a very important need for replacement fossil fuel with renewable sources of energy. Greenhouse effect is considered one of bad effects of fossil fuels, which causes increase of global temperature. Biodiesel is one of fossil fuel alternatives, which can be produced from many organic sources. Scientists are searching for adding nanomaterials to fueling system, which can modify fuel characteristic in compression champers. In this study diesel fuel will be replaced with blends of diesel and biodiesel produced from waste cooking oil (WCO) is created using a catalytic transesterification reaction (CTR). With the addition of a low concentration of alcohol over the period of an hour at a reaction temperature of 65 °C, (CTR) converts (WCO) to methyl esters. Blends consisting of (40 % diesel, 60 % biodiesel and CuO nano-martial with different concentration) will be prepared for fueling direct injection engine four-stroke. The engine will be run at 1400 rpm with natural aspiration under various loads. Using blends of (pure diesel, B40 [consist of 60 % biodiesel and 40 % diesel], 50b40 [consist of 60 % biodiesel, 40 % diesel and 50 mg CuO], 100B40 [consist of 60 % biodiesel, 40 % diesel and 100 mg CuO], 150 [consist of 60 % biodiesel, 40 % diesel and 150 mg CuO] and pure diesel). On engine performance and emissions, the impact of using copper oxide has been studied. The results of the experiment demonstrate that diesel engines can run on various mixtures of fuel, biodiesel, and CuO nano-material under the same operating conditions. The obtained data indicates that a 10% increase in brake thermal efficiency was noted, decrease in exhaust temperature with 11.6 % and decrease in brake specific fuel consumption with 6.66 %.

“…Internal combustion engine vehicles will become less common over the coming decades and eventually go out of production [4,5], although research and development will keep going in the interim to make them more cost-effective and environmentally [6][7][8]. Shortly, it is anticipated [9] that both the detrimental effects of greenhouse gas emissions on the environment and our reliance on fossil fuels decrease [10][11][12][13].…”

One of the major issues, the energy crisis, makes the globe dangerous and violent [1]. Every day, there is an increase in energy demand. Resources of energy are running out swiftly, and all indicators point to their impending demise. In such cases, renewable energy sources must be given more consideration. The widespread use of fossil fuels renders them unsustainable because they increase CO2 levels and emit greenhouse gases that harm the environment [2]. With several trials of usage of HHO gas or compressed natural gas as a fuel performance improver on both internal combustion engines powered by gasoline or diesel up until this point, many advancements have been made in this field[3]. This paper comprises a survey of the numerous advancements that have occurred in this area. There was a net lead to an amplified in brake power from 2.1% to 5.8% and an increase in brake thermal efficiency from 10.27% to 35% with the addition of HHO gas. The usage of traditional fuels decreased by 20% to 30%, and HC and CO exhaust emissions decreased by an average of 14% and 18%, respectively.
