“…It is worth noting that H 2 substitution levels, as seen in the study by Barrios et al, remained relatively low, not exceeding 21% HES. However, Wu et al [52] clearly found an increase in NO x emissions with the addition of H 2 , regardless of HES and engine load. This is due to the higher combustion rate of hydrogen compared to diesel fuel.…”

“…For conventional vehicle engines used in commercial applications, numerous studies have demonstrated that the incorporation of H 2 enables a positive impact on the BTE across all load ranges. Hoang and Pham [50], Yilmaz and Gumus [51], and Wu et al [52] reported an improvement in the combustion process, which increased the BTE, due to H 2 's high diffusivity and flame propagation. Barrios et al [49], however, did not find a clear trend, arguing that the lack of EGR control would influence the combustion process.…”

The use of compression ignition engines (CIEs) is associated with increased greenhouse gas emissions. It is therefore necessary to research sustainable solutions and reduce the negative environmental impact of these engines. A widely studied alternative is the use of H2 in dual-fuel mode. This review has been developed to include the most recent studies on the subject to collect and compare their main conclusions on performance and emissions. Moreover, this study includes most relevant emission control strategies that have not been extensively analyzed in other reviews on the subject. The main conclusion drawn from the literature is the negative effect of the addition of H2 on NOx. This is due to the increase in temperature during combustion, which increases NOx formation, as the thermal mechanism predominates. Therefore, to reduce these emissions, three strategies have been studied, namely exhaust gas recirculation (EGR), water injection (WI), and compression ratio (CR) reduction. The effect of these techniques on NOx reduction, together with their effect on other analyzed performance parameters, have been deeply analyzed. The studies reviewed in this work indicate that hydrogen is an alternative fuel for CIEs when used in conjunction with techniques that have proven to be effective in reducing NOx.

“…However, hydrogenation processes can be applied to biodiesel to enhance its properties. Hydrogen, as a clean energy carrier, has a wide range of applications and can be produced through methods like electrolysis using renewable sources [26][27][28]. Akcay et al [29], Das et al [30] and Kanth et al [31] conducted trials on a diesel engine fueled with a blend of diesel and WCO, supplemented with hydrogen and air.…”

Waste cooking oil is an attractive feedstock for biodiesel production because of its low cost and availability. This research delved into the viability of utilizing waste cooking oil at varying blend ratios 10%, 15%, and 20% in conjunction with different levels of hydrogen enrichment (3 lit/min, 6 lit/min, and 9 lit/min) for a CRDI single-cylinder diesel engine. The study meticulously examined the impact of combustion parameters, specifically injection pressure (IP), hydrogen (H2) infusion, and waste cooking oil (WCO) inclusion. In terms of both performance and emission considerations, the investigation aimed to optimize these crucial combustion parameters. This was achieved through the implementation of a response surface methodology (RSM), with the primary objective of minimizing emission levels while maximizing engine performance. The emission aspect took into account notable reductions in key characteristics, including carbon monoxide (CO), nitrogen oxides (NOx), smoke, and hydrocarbon (HC) concentrations in the engine exhaust gases. Simultaneously, the performance facet entailed a discernible enhancement in fuel economy and an impressive 8-9% increase in Brake Thermal Efficiency (BTE).
