ンジンのインタクーラ装置。[Claims for Utility Model Registration] A temperature sensor is installed in the intake passage downstream of the compressor of the turbocharger to detect the temperature of the supercharged air; a boost pressure sensor that detects boost pressure; an intercooler that is disposed in the intake passage downstream of the temperature sensor and the boost pressure sensor to cool the supercharged air; a bypass passage that bypasses the intercooler; and a switching valve that selects and closes either the intercooler or the bypass passage, and is configured to close the intercooler side when it is determined that the temperature or pressure of the supercharged air is below a set value. In an intercooler device for a turbocharged engine, the exhaust pressure detection means detects the exhaust pressure in the exhaust passage of the engine, the determination means compares and determines the exhaust pressure and supercharging pressure, and the exhaust pressure is higher than the supercharging pressure. An intercooler device for an engine with a turbocharger, comprising: control means for driving and controlling the switching valve so as to close the intercooler side when it is determined that the intercooler side is closed.
