“…Lower cylinder pressure was previously reported for biodiesel combustion compared to diesel fuel [ 29 ]. In addition, Elkelawy et al [ 30 ] argued that this is because of the low self-ignition characteristics and heating contents of the biodiesel fuel, relative to diesel fuel [ 31 ]. The effect of adding the DEE additive into the B20 fuel blend slightly increased in-cylinder pressure by 1%, compared to B20.…”

“…From the other side, in the lean air/fuel mixture it causes low cylinder temperature. In addition, HC emission is also due to the a thin layer of fuel on the combustion chamber wall, which are due to fuel impingement during over spray [ 30 , 38 , 45 ]. Furthermore, the trapping of fuel in the combustion chamber of crevice areas is also considered as one of the major factors for the increase in HC emissions [ 43 ].…”

Biodiesel is considered as a key prospective renewable energy source in India. Hence, a study was carried out for the improvement of palm kernel oil biodiesel production using a transesterification process at different molar ratios. This study comprehensively examined all aspects of biodiesel from optimum production to the effect of additives on its combustion behavior. The optimum yield condition was validated with the MINITAB-17 software and analyzed using the Taguchi method. Two different additives, 5% diethyl ether (DEE) and 2000 ppm Butylated hydroxyltoluene (BHT), were also experimented. Engine experiments were conducted at constant speed (1500 rpm) and five different engine loads (0, 25, 50, 75 and 100%) on a single-cylinder direct injection diesel engine. Heat release rate, brake specific fuel consumption, brake thermal efficiency, engine emissions, such as CO, HC, NOx, and smoke opacity were analyzed. The maximum palm kernel oil (PKO) biodiesel yields, obtained at 55 °C, for the KOH and NaOH catalysts were 86.69% and 75.21% at the molar ratio of 6:1. B20BHT combustion showed 4.6% higher brake thermal efficiency (BTE). NOx emission was reduced by 19.4%, compared to the diesel fuel values. DEE resulted in higher CO and HC emissions compared to diesel fuel values by 39.2% and 7.6%, respectively, whereas smoke emission was improved by 11.5%.

“…Another study by Elkelawy et al used 2% and 4% H 2 O 2 emulsification to B50 biodiesel along with silver thiocyanide nanoparticles. 24 The authors also reported a substantial decrease in the reduction of NO x emissions despite an increase in the EGT. Increasing the H 2 O 2 emulsification to 4% resulted in higher BTE, in-cylinder pressures and lower brake-specific fuel consumption (BSFC), and the emissions of CO, HC, and NO x .…”

“…When the covalent bond is broken under ambient conditions, decomposition of H 2 O 2 can take place releasing vapors of oxygen and leaving behind water which is exothermic. 20 It finds applications in combustion 21,22 and engines [23][24][25] as oxidant and energy carriers due to its nature of readily vaporizing and releasing oxidants. The use of H 2 O 2 as an emulsifier has resulted in the improvement in the performance and reduction in the emissions of biodiesel and diesel-fueled engines.…”

Hydrogen peroxide (H 2 O 2 ) is an excellent oxidant carrier that finds its use in combustion and fuel applications. In the present study, H 2 O 2 (30% assay) is used as an emulsifier in waste cooking oil biodiesel blend (B20) and the emissions and performance in a compression ignition engine are assessed. Along with the neat B20, three blends of B20 with 0.5%, 1%, and 1.5% H 2 O 2 concentrations are used. Increasing the concentration of H 2 O 2 beyond 1.5% resulted in vapor lock in the fuel pump leading to a loss in injection pressure. An increase in the exhaust gas temperature was recorded with the increase in H 2 O 2 concentration due to improved fuel properties, like, cetane number, thermal conductivity, and microexplosions of fuel droplets. However, NO x emissions decreased mainly due to the presence of the hydroperoxyl group from H 2 O 2 . Analysis of variance was also carried out to assess the statistical significance of H 2 O 2 on the responses and is seen that the maximum impact of H 2 O 2 was positively influencing brake thermal

The search for an effective solution to improve performance and emission characteristics of internal combustion (IC) engines used in the commercial sector is regarded as one of the most important and essential issues in recent years due to increasing levels of pollution. Nanoparticles with their additive ability to increase fuel reactivity and atomization, due to their large surface area and high heat transfer coefficient, can improve the performance and emission characteristics of a fuel. This review highlights the use of nanoparticles as fuel additives to enhance the emission and performance characteristics of IC engines. Detailed comparisons of performance, emission, and combustion characteristics of IC engines using fuels blended with nanoparticles have been done. Nanoparticles were observed to be an oxygen buffer for fuel combustion and boost fuel atomization, thus enhancing engine performance. While alumina exhibited a decrease in levels of HC and CO but a considerable increase in NOx, graphene nanoparticles and ceria were found to be particularly effective in enhancing engine performance. Detailed study has been done on other nanoparticles, including metal‐oxide, nonmetal‐oxide as well as carbon nanoparticles. Overall, the use of nanoparticles can enhance the thermophysical characteristics of fuels, improving the emission and performance characteristics of engines. The review suggests that selecting the right dosage and variety of nanoparticles is crucial for optimizing engine performance, and thus directly helps in tackling the ongoing pollution problem.
