されずに排出されることになり、不経済である。 For example, in ships, exhaust gas from an internal combustion engine operates an exhaust turbocharger via an exhaust turbine, thereby supplying combustion air from the supercharger to the internal combustion engine. In this conventional configuration, when the internal combustion engine is under low load, the operation of the supercharger tends to be delayed, but when the internal combustion engine is running at rated speed, the performance of the supercharger improves, and the intake air amount and pressure are lower than the internal combustion engine. There are often cases where the value exceeds what the institution requires. Therefore, in conventional configurations like this, the turbocharger's differential user and exhaust turbine nozzle ring are replaced to bring the supply air amount and pressure close to the values required by the internal combustion engine. The performance of the internal combustion engine decreases, and the exhaust gas energy of the internal combustion engine is emitted without being effectively utilized, which is uneconomical.

できるものである。 Therefore, the present invention provides an exhaust turbo supercharger-driven generator-motor device that solves this problem, and is characterized by an exhaust turbo supercharger that is operated by the exhaust gas of an internal combustion engine via an exhaust turbine. The first generator motor is connected to the rotating shaft of the engine, the second generator motor is connected to the main shaft of the internal combustion engine, and the first and second generator motors are electrically connected to each other. According to this configuration, when the load on the internal combustion engine is low, the second generator motor is operated by the internal combustion engine to generate electricity, and the generated power is used to generate electricity in the first generator.
The generator motor is activated to operate the supercharger, thereby actively supplying air to the internal combustion engine. Therefore, the auxiliary blower that was conventionally required is not necessary, or even if it is necessary, it can be made smaller. In addition, when the internal combustion engine is operating at its rated capacity, the supercharger generates the supply air pressure and amount of air necessary for the internal combustion engine, operates the first generator motor to generate electricity, and adds the generated power to the second generator motor. It rotates in synchronization with the main shaft of the internal combustion engine, thereby adding torque to drive the main shaft, and making it possible to match the intake air amount and pressure required by the internal combustion engine with those of the supercharger. Therefore, there is no need to reduce the performance of the supercharger to match the internal combustion engine as in the past, and the exhaust gas energy of the internal combustion engine can be effectively utilized to improve its performance.
