Abstract
An energy recovery apparatus for a turbo compound engine is provided having: an exhaust turbine with a first rotary machine in an exhaust pipe of an internal combustion engine; a second rotary machine mounted on a wheel axle of a motor vehicle, which is driven by the internal combustion engine, and an exhaust turbine coupled to the exhaust port of the first-mentioned exhaust turbine; and a third rotary machine operable as a generator. The energy recovery apparatus also includes a first sensor for detecting the speed of rotation of the internal combustion engine and a second sensor for detecting the load on the engine. The first through third rotary machines are controlled by signals from the sensors and efficiently utilize the exhaust energy carried by the exhaust gas discharged from the internal combustion engine.
