Thermo-ecological performance optimisation and analyses of an engine running with a modified power generating cycle are carried out based on effective ecological power density (EFECPOD) and effective ecological performance coefficient (EFECPEC). They provide a unique value for combined characteristics of thermal efficiency, power, cycle volume, entropy generation and maximum combustion temperature. The impacts of design and operational parameters such as compression ratio, equivalence ratio, engine speed, exhaust temperature ratio, pressure ratio, cycle pressure ratio and cycle temperature ratio on maximum EFECPOD and EFECPEC have been examined for modified power generating cycle.
