The deposition and dispersion of particulate matter from diesel combustion in confined spaces pose significant challenges to air quality public health, with important implications for sustainable development goals. While previous studies have focused on particle behavior inside engines, the external environmental effects remain poorly understood. This study systematically investigated mass concentrations characteristics PM1, PM2.5, PM10 particles a 1 m3 chamber under both sealed ventilated conditions. experimental results demonstrated that natural ratios reached 50–75% after 8 h across all sizes. A comparative evaluation ventilation strategies showed lateral achieved superior reduction 36%, outperforming direct at 14–22% non-ventilated conditions 23%. revealed ventilation-induced convective removal was more effective than gravitational settling alone, providing technical insights management enclosed environments. These findings offer valuable scientific guidance optimizing systems while contributing solutions pollution control. research advances our understanding supports technological innovations cleaner urban infrastructure.
