Gas pressure and exhaust heat of the combustion exhaust gas exhausted from the internal combustion engine is effectively utilized for generating electricity. Using a turbocharger (8) having a turbine (4) that is driven by gas pressure of the combustion exhaust gas and a compressor (6) that is driven by rotational force generated in the turbine, an air engine (12) generating rotational force by air pressure as a power source, and a generator (14) converting the rotational force generated by the air engine to electric power, the air inspired from outside is compressed by the compressor of the turbocharger and heated by the turbine heat at high temperature, and electricity is generated by the generator using the generated compressed air of high pressure and high temperature as a power source of the air engine. The compressed air thus generated in the turbocharger (8) is shared and distributed for combusting the internal combustion engine (2) and for driving the air engine (12).
