The transition toward sustainable energy solutions has become a strategic priority for modern defence organizations. This study evaluates the impact of hydrotreated vegetable oil (HVO) and its blends on the performance and emissions of a compression ignition engine (OM 366 LA II), which represents the mid-range logistics vehicles deployed by the Lithuanian Armed Forces. Numerical simulations were performed using the Diesel-RK software and validated against engine manufacturer performance data, achieving a mean absolute torque difference of 0.64%. The results indicate that increasing the HVO fraction reduces brake specific fuel consumption (BSFC) and nitrogen oxides (NOx) emissions.

Over the past decades, environmental protection, including regulation of air pollution, has become an important economic and political issue. Although aviation accounts for only 2% of atmospheric pollution, regulation at national, international and global level is still very important.
