Claims

[Scope of utility model registration request]

In an engine equipped with an intercooler equipped with a turbocharger, in which intake air compressed and inhaled by a turbocharger is cooled and supplied to the engine by an intercooler provided in an intake passage, a bypass passage is provided in the intake passage that directly connects an upstream side and a downstream side of the intercooler. A valve capable of opening and closing the bypass passage is disposed in the bypass passage, and a temperature sensor capable of detecting the temperature of intake air passing through the intake passage is provided downstream of the turbocharger, and a detected value of the temperature sensor is provided. The valve is connected to be openable and closable based on the temperature sensor, and the bypass passage is opened when the detected value of the temperature sensor is below a predetermined temperature, and the bypass passage is closed when the detected value is above the predetermined temperature. A turbocharged engine equipped with an intercooler.
