Therefore, a coolant different from the engine coolant can be used as the coolant for the intercooler 30 and the downstream intercooler 50. For example, it is possible to use a coolant that is superior in heat exchange with air as compared with engine coolant.
- the cooling water pump 312 is provided below the engine 13, but the cooling water pump 312 and the cooling water pump 421 may be arranged above or behind the engine 13.
