<P>PROBLEM TO BE SOLVED: To provide a drive system that recovers the heat of exhaust gas while allowing high output. <P>SOLUTION: The drive system includes: a first internal combustion engine 10 having a first drive shaft 12; a second internal combustion engine 20 having a second drive shaft 22; an output shaft 71 rotated by power from the first drive shaft 12 and the second drive shaft 22; and a control means 80. When the temperature of the first internal combustion engine 10 is a first predetermined temperature or higher, and the temperature of exhaust gas of the second internal combustion engine 20 is a second predetermined temperature or higher, the control means 80 permits water vaporization expansion operation of the first internal combustion engine for vaporizing and expanding the water in water-containing liquid by the heat of exhaust gas of the second internal combustion engine 20 to rotate the first drive shaft 12. <P>COPYRIGHT: (C)2012,JPO&INPIT |
