| Abstract: | 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%. |
