In the fuel injection phase of a diesel engine, temperature and pressure within cylinder surpass fuel's critical point, entering supercritical state. This condition significantly affects evaporation atomization processes cylinder. study conducted an experiment on droplets under conditions using high-temperature, constant-volume droplet apparatus. A molecular dynamics model was developed to simulate in nitrogen environment, composed mixture two components: 85.1 mol. % n-dodecane 14.9 isooctane. The focused process sub-supercritical analyzing changes clusters near interface during elucidate relationship between these clusters. findings indicate that lifetime decreases with rising ambient pressure, effects being more pronounced subcritical environment. enrichment molecules is 40% environment 164% suggesting phenomenon conditions. At temperatures, temperature's influence primarily through accelerating initial heating droplet. An increase leads higher number proposes five levels based varying they contain, different transforming into one another. For each increment cluster level, forces by approximately 0.025 kcal/mol Å. environments, distinct exists atmospheric gas, resulting fewer Conversely, this clear replaced layer, which facilitates formation numerous, larger
