The world is forced to look for alternative ways of energy production due to the depletion of fossil fuels and many critical pollution problems that harm the environment. The most important alternative source of energy is biodiesel which is a type of fuel synthesized from natural resources such as agriculture wastes, used cooking oil, animal fat, and algae. Biodiesel is eco-friendly fuel and has characterized over petrodiesel by its lower aromatics, sulphur, and carbon emissions. Therefore, many countries currently use diesel-biodiesel blends as a fuel for many applications. Although this blend has many advantages, it has a critical disadvantage that it emits nitrogen oxides (NOx) gases when burning higher than pure diesel. In our study, we prepared different nano additives with different concentrations (50 and 100 ppm) to be added to the diesel-biodiesel blend (B30), then investigate their effect on NOX, Carbon mono oxide (CO), and smoke emissions. The prepared nano additives were nano amorphous titanium dioxide (TiO2), nano Copper oxide (CuO), and nano zinc oxide (ZnO). All prepared additives achieved a remarkable reduction in emission compared with diesel-biodiesel (B30) blend. Nano amorphous TiO2 achieved a superior reduction in all emissions compared to pure diesel and neat B30 as it achieves the highest NOx emissions reduction by 43.46% compared to B30 blend emissions at load 2 Nm and a concentration of 100 ppm. Additionally, the same concentration achieved 35% reduction in NOx emissions compared to pure diesel emissions at the same load. For the other additives, ZnO and CuO when added to B30 achieves a considerable reduction in emissions compared to neat B30, but when compared with neat diesel the nano additives exhibited a varied emission reduction.

As an additive for diesel engines, copper oxide nanoparticles (CuONPs) are thought to offer a lot of promise. In this work, an experimental investigation was conducted to ascertain the impact on a diesel engine of adding copper oxide (CuO) particles made from a Rubus fruticosus leaf extract product using a novel green synthesis approach. The presence and morphology of the CuO were analyzed by different characterization studies. Subsequently, was investigated the effects of the addition of CuONPs at two concentrations (15 and 20 ppm) on diesel engine performance, brake‐specific fuel consumption (BSFC), carbon monoxide (CO), hydrocarbon (HC), nitrogen oxide (NOX), and smoke emissions. From the experimental outcomes, the D100 + 20 ppm CuO blend shows a significant reduction in CO, HC, and smoke emissions by 58.19%, 25.15%, and 26.67%, respectively, when compared with standard diesel. Also, it was found that the D100 + 20 ppm CuO blend showed better engine performance with enhanced combustion characteristics. The experimental results provided a reduction of around 1.10% in BSFC. This study demonstrates how changes in fuel composition through the addition of nanoparticles to commonly used diesel fuel can provide meaningful improvements in engine performance and emissions.

“…The graph indicates that CuO nanoparticles yield lower HC emissions in biodiesel compared to TiO2 nanoparticles, likely due to their higher surface reactivity. This increased reactivity enables better interaction with fuel molecules, resulting in more efficient combustion as shown below figure 11 [21].…”

In this groundbreaking experimental study, examines the impact of copper oxide (CuO) and Titanium oxide (TiO2) nanoparticles on both emissions and performance of a 4.1.5 kW diesel engine fueled by waste cooking oil biodiesel. B20 test fuel blends fortified with 50 ppm concentrations of CuO and TiO2 nanoparticles, subjected to rigorous testing across diverse engine loads (20%, 40%, 60%, and 80%) while maintaining a constant speed of 1,500 rpm. Through meticulous evaluation of key performance metrics such as brake thermal efficiency (BTE) and brake-specific fuel consumption (BSFC), coupled with the analysis of emissions including CO, CO2, HC, and NOx, we observed remarkable enhancements. Notably, the introduction of 50 ppm copper oxide and titanium oxide nanoparticles into biodiesel blends resulted in a notable boost in brake power (BP) and BTE, showcasing a remarkable surge from 12.39% to 22.14% in BP and 4.92% to 15% in BTE, underscoring their profound impact of particular significance, B2050CuO exhibited superior combustion characteristics compared to titanium nanoparticles, leading to elevated flame temperature and reduced ignition delay, thereby translating into improved engine performance, enhanced braking power output, and overall superior brake thermal efficiency. Furthermore, CuO and TiO2 nanoparticle blends demonstrated a significant reduction in CO emissions at full load with a 50 ppm dosage, achieving reductions of 6.32%, 8.57%, and 6.25%, respectively. Moreover, for B20 and B2050 TiO2 blends, HC emissions saw a notable drop by 9.14%, 6.57%, and 2.817%, promoting efficient combustion through enhanced fuel molecule interaction. Comparatively, the inclusion of B20, B2050TiO2, and B2050CuO fuel blends led to substantial reductions in CO2 levels by 14.4%, 4.8%, and 3.75%, along with lowered NOx emissions by 5.2%, 3.125%, and 2%, highlighting their potential in mitigating environmental impact."
