ジンの吸気装置。[Claims for Utility Model Registration] An intercooler is provided between the turbocharger and the throttle valve in the intake passage of the engine, and a bypass passage that bypasses the intercooler is provided between the downstream of the turbocharger and the upstream of the throttle valve. In an intake system for a turbocharged engine, in which an intake control valve for controlling the flow of intake air is arranged in the bypass passage, the intercooler has a cooling core downstream of the intercooler. In the intercooler, at least a downstream chamber in the intercooler is always connected to the intake passage, and the engine is provided with the intake control valve when the vehicle is in a deceleration driving state. to cause intake air to flow through the bypass passage and not to flow the intake air to the intercooler, and when the vehicle is in a driving state other than a deceleration driving state, the intake control valve is operated to flow the intake air to the intercooler. and a second means for controlling the intake control valve to allow intake air to flow into the bypass passage and not to send intake air to the intercooler when the vehicle enters an accelerated driving state. An intake system for a turbocharged engine, characterized in that it is provided with means.
