PROBLEM TO BE SOLVED: To quickly warm up an engine.SOLUTION: A supercharging system 1 includes: a supercharger 2 including a turbine 2a to be rotated with exhaust gas from an engine E, and a compressor 2b for raising the pressure of intake air with the rotating power of the turbine and supplying the pressure-raised intake air to the engine; a supply passage 6 in which the compressor of the supercharger is arranged, and into which the intake air to be supplied to the engine is distributed; an exhaust flow path 3 in which the turbine of the supercharger is arranged, and which exhausts exhaust gas from the engine to the outside; a split flow path 11 branching from the exhaust flow path for splitting the flow of part of the exhaust gas flowing in the exhaust flow path; and a heat exchanger 13 arranged in the supply passage upstream of the compressor of the supercharger for making a heat exchange between the exhaust gas flowing in the split flow path and the intake air before supplied to the supercharger, to raise the temperature of the intake air with the heat of the exhaust gas. |
