NOVELTY - The apparatus has a motor generator (200) connected to a rotary shaft (120) of a valve assembly (100). The motor generator is fixed in a first instance to generate electricity by utilizing rotational force transmitted by the rotary shaft, where the motor generator is fixed in second instance to apply torque to the rotary shaft. A controller i.e. hardware device (300) such as memory and processor, fixes the rotary shaft of the valve assembly at a predetermined angle in the first instance and adjusts speed of rotation of the rotary shaft by controlling the motor generator in the second instance.    USE - Apparatus for recovering exhaust gas kinetic energy from an internal combustion engine of a vehicle. Uses include but are not limited to a motor vehicle i.e. passenger automobiles such as sports utility vehicles (SUV), buses, lorry and commercial vehicles, watercraft such as boats, ships and aircraft, hybrid vehicles such as petrol-powered and electric-powered vehicles, electric vehicles, plug-in hybrid electric vehicles, hydrogen-powered vehicles and alternative fuel vehicles.    ADVANTAGE - The apparatus enables energy management and improves environmental impact by generating electricity via recovering kinetic energy of an exhaust gas that is ejected under high pressure. The controller reduces discharge noises of exhaust gas by fixing a flap at a predetermined angle by utilizing the motor generator. The motor generator is fixed with an inner side of a space section and an exhaust gas pipe to generate electricity by recovering kinetic energy from exhaust gas without adding any exhaust gas pipe to a system, thus reducing cost of materials, weight of a vehicle and required workload. The flap of the valve assembly is adjusted parallel to ejection flow of exhaust gas when the vehicle is being accelerated so as to minimize occurrence of backpressure and maintain vehicle acceleration. The apparatus can discharge exhaust gas from the inner side of the exhaust gas pipe by forcibly rotating the flap by utilizing the motor generator when the vehicle is being driven from a stopped state, thus improving engine torque and fuel efficiency. The space section is formed with a side of the exhaust gas pipe and the valve assembly, thus preventing resistance from occurring when ejecting exhaust gas.
