Comprehensive Performance Assessment of Dual Loop Organic Rankine Cycle (DORC) for CNG Engine: Energy, Thermoeconomic and Environment

The improvement of the overall utilization rate compressed natural gas (CNG) engine fuel is basis efficient energy utilization. On foundation heat balance theory internal combustion engines, this study fully considers operation characteristics CNG engines and systematically analyzes distribution different waste under variable working conditions. nonlinear relationship between speed intercooler source becomes evident with increasing intake mass flow rate. In accordance structural characteristics, thermodynamic model, transfer model environmental dual-loop organic Rankine cycle (DORC) are constructed. system potential in full environments evaluated. Compared speed, airmass has a significant effect on comprehensive performance loop. maximum power, area power output per unit (POPA) DORC 36.42 kW, 23.34 m2, 1.75 kW/m2, respectively. According to operating loops, variation laws loop influence multiple parameters analyzed. synergistic variables also
