PURPOSE:To secure an air charging state suitable for a state of engine operation, by controlling an on-off valve inside an intercooler by means of an input signal of one side or both of eingine speed and load. CONSTITUTION:A signal 15 out of an engine speed sensor and a signal 16 cut of a load sensor bot are inputted into a control unit 14. When both on-off valves 12 and 13 come into a state of being opened, flow passage resistance in an intercooler 4 is small. When these on-off valves 12 and 13 are close, increment in an air charging quantity is checked whereby charging temperature is dropped. In time of opening or closing these on-off valves 12 and 13, these operations are made to correspond to that of a waste gate device. |
