<p><P>PROBLEM TO BE SOLVED: To provide an intercooler temperature control device capable of quickly regenerating an exhaust gas filter, by adjusting the air temperature flowing out of an intercooler, even in an engine with a supercharger. <P>SOLUTION: This intercooler temperature control device has the supercharger 11 supercharging air to the engine 10, the intercooler 12 cooling the air raised in the temperature by being compressed by the supercharger 11, a low temperature circuit A supplying a low temperature cooling medium to the intercooler, a high temperature circuit B supplying a high temperature cooling medium to the intercooler, and a circuit switching means 14 switching a circuit of supplying the cooling medium to the intercooler to the low temperature circuit A or the high temperature circuit B, and raises the temperature of the air flowing out of its intercooler 12, by switching the circuit of supplying the cooling medium to the intercooler 12 to the high temperature circuit B from the low temperature circuit A, by controlling the circuit switching means 14 when becoming the regeneration timing of the exhaust gas filter 13 for capturing a particulate included in exhaust gas. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
