“…It has been stated that the BTE increases due to the high surface area of nanoparticles and the storage of energy in the nanoparticles [42]. The current results are in agreement with Fayad et al [43] and Patel et al [44]. It has been reported that the addition of 50 mg per The variation in the BTE with the engine load due to the effect of a high rate of EGR and the addition of TiO 2 concentrations into the castor oil blends is shown in Figure 4.…”

The developments in the field of nano-additives have increased in the recent years due to the desire to reduce the level of exhaust emissions in diesel engines. The soot characteristics of particulate matter (PM) and nitrogen oxides (NOX) were experimentally investigated using two concentrations of titanium dioxide (TiO2) as nano-additives (25 ppm and 40 ppm) blended with C20D (composed of 20% castor oil methyl ester and 80% diesel fuel) and 30% exhaust gas recirculation (EGR). The combustion of C20D + TiO2 increases brake thermal efficiency (BTE) by 2.8% in comparison with neat C20D, while a significant reduction was obtained in BSFC 6.5% and NOX emissions were maintained at a level parallel with diesel. The results indicated that the technique involving a high EGR rate and the addition of 25 ppm and 40 ppm of TiO2 nanoparticles to the C20D exhibits better reductions in NOX emissions by 17.34% and 21.83%, respectively, compared to the technique comprising the use of C20D + TiO2 and C20D. The reduction in the total concentration of PM via the addition of TiO2 nanoparticles to the C20D was 26.74% greater than neat C20D and diesel. In contrast, the incorporation of a high rate of EGR with C20D +TiO2 increased the PM concentrations by 16.85% compared to the technique without EGR. Furthermore, the high concentrations of TiO2 nanoparticles (40 ppm) in the C20D produced 19 nm smaller soot nanoparticles compared to the 23 nm larger soot nanoparticles produced from the low concentrations of TiO2 nanoparticles (25 ppm) added into the C20D. The current investigation reveals that the reduction in NOX emissions and the production of soot nanoparticles notably improved due to the synergic effect of EGR, the TiO2 nanoparticles, and biodiesel.

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.

“…Nitrogen oxides (NO x ) and carbon monoxide (CO) are the most harmful emissions from the combustion of conventional fossil fuels, which have significant impacts on public health, the climate, and our fragile ecosystems [1]. Of the many alternate fuels proposed to reduce the emissions, biodiesel provides a compromise between performance and emissions as it releases fewer sulphur oxides, less carbon dioxide, and less soot while inherently having a low calorific value [2,3]. Hence, biodiesel's NO x and CO emissions have been one of the research interests as it is widely considered as a drop-in replacement for diesel engines [4].…”

Biodiesel is one of the most promising fossil fuel replacements for automotive engines, furnaces, and turbines due to its sustainability, energy savings, and reduced carbon emissions. While commonly reported in engine studies, nitrogen oxides (NOx) and carbon monoxide (CO) released from combustion of biodiesel have not been studied in laminar diffusion flames. This numerical study examines the concentrations of NOx and CO emissions of the laminar biodiesel diffusion flames at different carbon flow rates and then compares its emissions with those of two liquid hydrocarbon fuel surrogates, n-heptane and iso-octane. A consistent carbon flow rate of 17.2 g/h is applied at the fuel inlet to compare the NOx and CO emissions of the three liquid fuels. The results show that biodiesel diffusion flame produces greater NOx and CO emissions with increasing carbon flow rate. At the same flow rate, n-heptane produces the greatest NO with 2.1% greater than biodiesel and 4.2% greater than iso-octane. The primary pathway for generating NO in biodiesel flame is the prompt pathway, with significant contributions from the thermal and NO2 decomposition pathways. While the NO productions in n-heptane and iso-octane flames are predominantly through the thermal pathway. It is also observed that biodiesel produces the greatest CO emission with 3.2% more than those of n-heptane and iso-octane. The oxidisation reaction of CO, CO + OH = CO2 + H primarily controls the CO mass fraction in the product for all fuels.
