“…For instance, the shipping industry must focus on achieving the dual carbon strategy due to consuming millions of tons of fuel annually, increasing greenhouse gas emissions. While the main source of greenhouse gas emission lies in internal combustion engine exhausts of the engine, proper assessment of materials used in the design of the parts is vital for efficient fuel performance [51][52][53][54].…”

Several types of research have been carried out on using alternative biofuel in internal combustion engines to salvage the depletion of fossil fuels. While most of these studies focused on the emission characteristics and control of global warming, little attention has been given to the corrosion, wear, thermal behaviour, and compatibility of the internal combustion engine materials to biodiesel. Thus, this study focused on the various corrosion and wear mechanisms associated with the internal combustion engine components like piston and cylinder heads, as well as the thermal behaviour efficiencies of the engine after interaction with the biodiesel fuels. The review cut across the wear study of internal combustion engine materials in varying fuel environments. Thermal analysis of different materials applied for internal combustion engines for sustainable fuel media. Corrosion study of various materials employed in the application of ICE engines. Also, the study discusses some significant challenges related to the compatibility of ICE with biodiesel and gaseous fuels. The study’s outcome indicates that an adequate fuel blend with nano additives can help improve the combustion process, emission reduction, and thermal efficiency of the internal combustion engine components. Furthermore, practical design in the internal combustion engine components like pistons will help compatibility with the material in the biodiesel blends, thus reducing wear, corrosion, and other failures associated with the internal combustion engine.

“…Usually, an exhaust gas recirculation (EGR) system is utilized to enhance the engine's thermal burden and NOx emissions. The implementation of an EGR system is an effective solution for addressing the issues of increased thermal burden, knocking tendency, and NOx emissions in natural gas engines under equivalent combustion modes [11,12]. EGR systems with high pressure are typically favored in heavy-duty engines owing to their EGR can effectively address the emission issue of natural gas engines with equivalent combustion.…”

Equivalent combustion natural gas engines typically utilize exhaust gas recirculation (EGR) systems to tackle their high thermal burden and NOx emissions. Variable nozzle turbochargers (VNT) can increase the engine intake and EGR rate simultaneously, resulting in NOx reduction while ensuring robust power performance. Using a VNT along with engine bench testing, the impact of VNT- and EGR-coordinated control on the performance and emissions of equivalent combustion natural gas engines was investigated under different operating conditions. Subsequently, multi-objective optimization was performed using a support vector machine. The results demonstrated that the use of VNTs in equivalent combustion natural gas engines could bolster the capacity to introduce EGR under several operative conditions and extend the scope of EGR regulation, thereby decreasing the engine’s thermal burden, improving fuel efficiency, and curbing emissions. Owing to the implementation of a multi-objective optimization method based on a support vector regression model and NSGA-II genetic algorithm, VNT and EGR control parameters could be optimized to slightly improve the economy and significantly reduce NOx emissions while maintaining the original engine power performance. At 20 operating points optimized for validation, brake-specific fuel consumption (BSFC) and NOx decreased by 0.94% and 47.0%, respectively, and CH4 increased by 3.7%, on average.
