PURPOSE:To satisfactorily recover an energy by providing an exhaust gas turbine which recovers a kinetic energy contained in exhaust gas of an internal combustion engine and a heat-exchanger and a compressor which recover a thermal energy contained in the exhaust gas. CONSTITUTION:After passing through a pipe 3, the exhaust gas of an internal combustion engine 1 directly drives a gas turbine 4. Compressed air fed out of a compressor 10 is subjected to e heat of the exhaust gas passing through a heating passage 7, passes through a pipe 14 and turns the gas turbine 4. In such a manner as above, a kinetic energy contained in the exhaust gas of the internal combustion engine is recovered by the exhaust gas turbine 4 and a thermal energy contained in the exhaust gas is absorbed in the compressed air via a heat-exchanger 6 and converted into the kinetic energy, which is recovered by the exhaust gas turbine. Thereby, the exhaust gas energy of the internal combustion engine may be effectively recovered. |
