These vehicles face significant challenges in electrification due to their high payload demands, making combustion-based technologies crucial for decarbonization efforts. The DMDF technology has demonstrated the potential to achieve ultra-low NOx and soot emissions, offering a significant advantage by reducing or eliminating the need for costly after-treatment systems. Moreover, this approach opens up opportunities for integrating alternative fuels, providing a viable pathway toward carbon neutrality in the transportation sector. Despite its advantages, there are still technical challenges, particularly in achieving the necessary exhaust gas recirculation ratios and boost pressures at low engine speeds with conventional turbocharger systems. Highly premixed combustion concepts like the RCCI approach used at partial loads in the DMDF engine require high EGR ratios while maintaining lean combustion, resulting in high boost demand and low exhaust energy, resulting in conditions difficult to match with a turbocharger optimized for conventional diesel applications. These limitations can hinder the full realization of DMDF technology's potential in real-world applications. This study addresses these challenges by evaluating the optimal turbocharger configuration for a 7.7 L dual-fuel engine operating under the DMDF concept. A series of turbocharger configurations were numerically analyzed using a calibrated GT-Power engine model to satisfy the air requirements of the dual-fuel system. A performance-based merit function identified a smaller compressor and turbine configuration as the optimal solution. Numerical results show potential improvements of compressor and turbine efficiencies of up to 5 % on each of the components, resulting in a reduction of up to 0.2 bar in pumping losses throughout most of the engine map and a significant increase in the VGT margin for optimization.The authors thank ARAMCO Overseas Company for supporting this research.
