TURBO-COMPOUNDING SYSTEM

The present invention relates to a turbo-compounding system that recovers power wasted by an internal combustion engine. The system of an embodiment of the present invention includes a supercharger, which includes a turbine that rotates by using the pressure of exhaust gas discharged from the internal combustion engine and a compressor that rotates by utilizing rotation force of the turbine to compress and supply new external air to the internal combustion engine; an electric motor generator that uses the rotational power of the compressor of the supercharger to rotate to generate electricityor to supplement the rotational power for the compressor of the supercharger; a power transmission shaft which connects the compressor of the supercharger and the electric motor generator; and a transmission which is provided on the power transmission shaft to change the speed of the power transmission shaft. 本发明涉及一种涡轮复合系统，其回收由内燃机废弃的动力，本发明的实施例的涡轮复合系统包括：增压器，其包括利用由内燃机排出的废气的压力旋转的涡轮机和利用所述涡轮机的旋转动力旋转而向所述内燃机压缩供应新的外部空气的压缩机；电动机兼发电
