摘要： Provided is an internal combustion engine for improving fuel-economy performance in any of the case where supercharging performed by an electric supercharger is required and the case where the supercharging is not required. The internal combustion engine includes: an electric supercharger; a supercharger; an electric motor; and a controller, the electric supercharger being for compressing an intake air by rotation of the supercharger caused with rotation of the exhaust turbine by an exhaust gas energy to perform supercharging and for rotationally driving the supercharger with electric-motor assistance by the electric motor; an exhaust bypass passage provided to bypass the exhaust turbine; and an opening and closing the exhaust bypass passage unit. In the internal combustion engine, the opening and closing the exhaust bypass passage unit opens the exhaust bypass passage until the supercharging is started by the electric supercharger.

摘要： In a controller of an internal combustion engine equipped with an electric supercharger driven by a motor, an object is to attempt to improve fuel consumption of a vehicle.The controller includes an electric supercharger driven by a motor; a generator that performs power generation using the output of the internal combustion engine as power; a charging device which is charged by the generator and can store electricity; and an accelerator opening degree detector that detects an accelerator opening degree. In the controller, a configuration is made such that, the controller controls supply electricity to the electric supercharger and generated electricity by the generator by the output of the accelerator opening degree detector, output needed for the electric supercharger calculated depending on the accelerator opening degree, and an state of charge in the charging device.
