The decarbonization of the operational fleet through implementation renewable and low-carbon fuels (LCFs) is considered a key factor in achieving regulatory greenhouse gas (GHG) reduction targets set by IMO EU. In parallel with optimizing engine energy efficiency emission characteristics during retrofitting for LCF operations, it equally important to assess ensure reliability components under permissible thermal mechanical loads. This study investigated factors influencing stresses on cylinder–piston assembly as engine’s operation shifts from diesel biodiesel, natural gas, methanol, or ammonia. methodological foundation this research was an original comparative analysis method that evaluates impacts stress combustion cycle factors. parameters were modeled using single-zone mathematical model. load determined based ALPHA (αgas) coefficient heat transfer intensity average temperature (Tavg). optimization simulated without changes structure (or “major” modernization, according terminology), modifications limited adjustment parameters. A characteristic transition LCFs significant increase maximum pressure (Pmax), stresses: ammonia, +43%; LNG, +28%; +54–70%; no changes. confirms adopted strategy maintain equal Dmax conditions. It emphasized that, after ensuring Pmax-idem conditions, aligns closely level minimal deviation. associated excess air (λ) controlled compression ratio within allowable variation ±1 unit. Based statistical correlations, rational λ identified, reaching up 2.5 units. Considering real-world marine engines, further will focus analyzing ISO 81/78, well E2 E3 cycles.
