The need to decarbonize the road transport sector is driving evaluation of alternative solutions. From a long-term perspective, biomethane and e-methane are particularly attractive as green energy carriers part solutions for sustainable freight on-road transport, they offer significant CO2-equivalent emissions savings in net Well-to-Wheel assessment. However, make methane-fuelled spark ignition (SI) heavy-duty (HD) engines competitive market, their efficiency must be comparable top-performing diesel applications that dominate sector. To this end, dilution techniques such exhaust gas recirculation (EGR) or lean air–fuel mixtures represent promising Within limits specific engine’s tolerance used strategy, charge can improve thermal impact on pumping wall heat loss, capacity ratio (γ). potential has never been explored case methane SI HD characterized by semi diesel-like combustion system architecture.
