Claims

[Scope of utility model registration request]

In an engine equipped with an exhaust gas turbocharger, the exhaust gas is circulated through the engine body via a cooling radiator for the charge air cooling system provided separately from the engine cooling radiator, and the above-mentioned engine cooling radiator or a bypass pipe parallel to this. A cooling water circulation path for the charge air cooling device that circulates cooling water from the cooling radiator for the charge air cooling device to the engine body via the charge air cooling device, and a variable throttle valve inserted in the cooling water circulation path for the charge air cooling device. and an electric fan that cools the radiator for cooling the charge air cooling device, and the temperature of the charge air drawn into the engine from the exhaust gas turbo supercharger through the charge air cooling device and the temperature of the cooling water. A water-cooled supply air temperature adjustment device comprising an electric fan and a controller that controls the throttle valve.
