摘　　要：基于一维数值仿真方法对某型船用低速二冲程柴油机展开机电复合增压技术的电机/发电机功率影响机制研究。研究结果表明:涡轮和压气机的效率是影响机电复合增压柴油机综合效率的关键因素;调节电机/发电机功率可以推动涡轮和压气机的运行工况点向最佳效率圈迁移,从而提高柴油机综合效率;通过应用机电复合增压技术可实现该机型全工况综合油耗降低0.5%~2.1%。The one-dimensional numerical simulation method was adopted to analyze the influence mechanism of electric-motor-generator power of hybrid turbocharger on the two-stroke low-speed marine engine. The results show that the efficiency of the turbine and compressor is the key factor affecting the overall efficiency of the hybrid turbocharging diesel engine;adjusting the electric-motor-generator power can push the turbine and compressor operating conditions towards the optimal efficiency circle, thereby improving the overall efficiency of the diesel engine;the hybrid turbocharging technology can reduce the overall fuel consumption of the engine by 0 .5%~2 .1%.
