“…Therefore, the effect is considered positive on one hand and negative on the other hand, and its final effect is complex. Consequently, when determining the added EGR, a trade-off should be made between NOX emissions and PM [11,12,13].…”

The fuel injection timings, equivalence ratio (Ø) and exhaust gas recirculation are considered the most important parameters can effect on combustion process and lower exhaust emissions concentrations. The influence of 15% EGR technology and operating parameters (Ø and injection timing) on NOX emissions and particulate matter (PM) using oxygenated fuel (ethanol and methanol) blends were investigated in this experimental study. The results showed that the NOX emissions concentrations with increasing the equivalence ratio (Ø) and applied EGR for all fuels studied. Besides, the E10 and M10 decreased the PM concentrations compared to the diesel fuel under various equivalence ratios (Ø). The applied EGR increased the PM concentrations, but when combination of oxygenated fuels and EGR leading to the decrease in the PM formation. The NOX emissions concentrations decreased from the combined effect of EGR and oxygenated fuels by 16.8%, 22.91% and 29.5% from the combustion of diesel, M10 and E10, respectively, under various injection timings. It is indicated that NOX emissions decreased with retarded injection timings, while the PM decreased under advanced injection timings.

“…It shows that the CO emission was decreases with increasing load, except full load condition for all fuel blends. It is due to lower air / fuel ratio and lower in-cylinder temperature at zero load condition has led to partial combustion, when increasing the load the surplus amount of oxygen and higher in cylinder temperature a rms complete combustion and resulted in lower emission of CO (Chandrasekaran et al 2016;Fayad and Dhahad 2021). at the same time, engine drawn more fuel to generate extreme torque at full load condition that results in more emission of CO(Tan et al 2012;Anchupogu et al 2018).…”

In present scenario, the fast depletion of fossil fuels and energy crises motivated the researchers towards finding an alternative sources for energy. In this work, the performance, combustion and emission of hydrothermally synthesized ZnO nanoparticles dispersed waste cooking oil biodiesel in single cylinder, four stroke, Direct Injection- Diesel Engine with eddy current dynamometer was investigated. The synthesized ZnO nano particles were characterized by XRD, FTIR, SEM and EDX to find crystallinity, functional groups and surface morphology. Waste cooking oil biodiesel was produced via conventional one step alkali catalyst Trans-esterification process. Test fuels were prepared with dispersion of ZnO nanoparticles in the concentration of 10ppm, 20ppm and 30ppm with B20 (20% waste cooking oil biodiesel and 80% diesel) with the aid of magnetic stirrer and ultra-sonication. The test results exposed that the addition of ZnO nanoparticles with B20 gave better Performance in terms of BTE and BSFC compared to B20. The addition of ZnO nano particles with 30ppm concentration was identified as better fuel among all tested fuels in this work. 30ppm addition of ZnO nano particles with B20 records 1.78 % increase in BTE and 10.34% decrease in BSFC. The emission like CO, HC and smoke were 20%, 15.4% and 17.39% lower than diesel. On the other hand NOx was slightly higher than diesel but lower than B20.

“…For both FIP, the NOX emissions increased during the combustion of C30D by 17.62% than to the diesel (Figure 7). This could have been due to the oxygen content in C30D that enhance the formation of NOX emissions [54,55]. Prior work reported that the chemically bound oxygen content in oxygenated fuels promote the NOX formation [56].…”

Next generation of fuels and injection technology system are growing attention in the transportation sector. The effects of castor oil of biodiesel (C30D) and two conditions (500 bar and 1000 bar) of fuel injection pressure (FIP) on soot nanoparticles characteristics and NOX emissions were performed in a direct injection (DI) diesel engine. The results showed that size distributions of soot particulate decreased from C30D combustion by 43.62% compared to the diesel combustion for different FIP. Furthermore, the soot particle number concentration decreased more with 1000 bar of FIP compared with 500 bar for both fuels tests. The combustion of C30D decreased the average number of primary particles (npo) by 44.35% compared with diesel. For an injection pressure, it was observed that high injection pressure (1000 bar) significantly decreased the npo by 11.6 nm and 25.4 nm compared to the 500 bar by 22.4 nm and 33.2 from C30D and diesel, respectively. In addition, the average diameter of soot primary particle (dpo) was smaller by 47.68% during C30D combustion than to the diesel combustion for all conditions of injection pressure. In case of engine performance, the BTE, BSFC increased from the C30D combustion compared with diesel under different FIP. It is indicated that increasing injection pressure improved the engine performance for C30D and diesel. In contrast, the high injection pressure and C30D increased the NOX emissions by 21.37% compared with diesel fuel.
