<P>PROBLEM TO BE SOLVED: To obtain an engine capable of improving combustion efficiency regardless of an engine operation state in the engine comprising a supercharger and an intercooler. <P>SOLUTION: The device comprises: the supercharger 2; the intercooler 3; an electric pump 9 for circulating cooling water in the supercharger 2 and the intercooler 3; a radiator 10 for cooling the cooling water circulated in the supercharger 2 or the intercooler 3; a first cooling water path 11 for circulating the cooling water from the electric pump 9 to the radiator 10 via the supercharger 2; a second cooling water path 12 for circulating the cooling water from the electric pump 9 to the radiator 10 via the intercooler 3; a bypass channel 17 for returning the cooling water circulated in the supercharger 2 to the electric pump 9 while bypassing the radiator 10; and a channel setting mechanism 13 for circulating the cooling water in the first cooling water path 11 to the bypass channel 17 when an intake air temperature is lower than a target temperature. <P>COPYRIGHT: (C)2013,JPO&INPIT |
