An internal combustion engine 1 is provided with a low-pressure supercharger LTC, which includes a low-pressure compressor wheel 54 arranged in an intake passage 20 and a low-pressure turbine wheel 64 arranged in an exhaust passage 30 and coupled to the wheel 54, and a high-pressure supercharger HTC, which includes a high-pressure compressor wheel 55 arranged in the intake passage 20 and a high-pressure turbine wheel 65 arranged in the exhaust passage 30 and coupled to the wheel 55. Part of a high-pressure compressor housing unit 52, which accommodates the high-pressure compressor wheel 55, and part of a high-pressure turbine housing unit 62, which accommodates the high-pressure turbine wheel 65, are both located in a space formed between a low-pressure compressor housing unit 51, which accommodates the low-pressure compressor wheel 54, and a low-pressure turbine housing unit 61, which accommodates the low-pressure turbine wheel 64. |
