Abstract：Based on the irreversible Otto cycle model and considering a variety of irreversible loss terms and the non-ideal gas specific heat model,NSGA-Ⅱ algorithm is used to optimize the dimensionless power and efficiency,dimensionless ecological function and dimensionless power density by single,double,three and four objective optimization.By comparing the deviation index of linear programming(LINMAP),TOPSIS and Shannon Entropy,the optimal scheme is obtained.The results show that compared with the single objective optimization,the multi-objective optimization has better results and better design scheme.
