Modeling of reciprocating internal combustion engines for power generation and heat recovery

► A power generation and heat recovery model for internal combustion engines is developed. ► The model provides performance/efficiency maps for electrical power output and thermal output. ► The model serves as an alternative to constant engine efficiencies or empirical efficiency curves. ► The simulation results using the proposed model are validated against manufacturer's data. ► The proposed model is coded in FORTRAN and a user-friendly tool was developed.
