Internal combustion engine with an exhaust gas turbocharger

An internal combustion engine with an exhaust gas turbocharger in communication with said engine by a charge air duct for supplying combustion air to said engine, said charge air duct including an intercooler with a housing having a cooling structure for cooling the air compressed by said turbocharger before it is supplied to said engine, an inlet area connected to an upstream section of said charge air duct which is connected to said turbocharger and, adjacent said inlet area, an outlet area connected to a downstream section of said charge air duct for supplying the charge air to said engine, an air flow switch back area provided in said intercooler housing opposite said air inlet and outlet areas, a first air flow control mechanism arranged between said inlet and outlet areas, a second air flow control mechanism disposed in said switch back area and operating means for actuating said air flow control mechanism including temperature sensing means for sensing engine operating temperature for holding said air flow control mechanism open until a predetermined engine operating temperature has been reached to permit the charge air to flow from said inlet area directly to said outlet area as long as said air flow control mechanism is open and to direct said air flow through the cooling structure of said intercooler when said flow control mechanism is closed.
