Abstract
An apparatus and method for recovering exhaust kinetic energy. The apparatus includes a valve assembly, a motor generator and a controller. The valve assembly includes a rotary shaft which is disposed in an exhaust gas pipe and a flap which is disposed on the rotary shaft. The flap is rotated by an exhaust gas that is ejected. The motor generator is connected to the rotary shaft of the valve assembly, and in a first instance generates electricity using a rotational force transmitted from the rotary shaft and in a second instance applies a torque to the rotary shaft. The controller fixes the rotary shaft of the valve assembly at a predetermined angle in the first instance and adjusts the speed of rotation of the rotary shaft by controlling the motor generator in the second instance.
