Abstract: An intake system for an engine is provided. The system includes a chamber room formed in an intermediate section of an intake passage, an intercooler disposed inside the chamber room, an intake air inlet chamber formed in a part of the chamber room upstream of the intercooler, an introducing portion for introducing intake air into the intake air inlet chamber, and a baffle plate dividing the intake air inlet chamber into an upstream space communicating with the introducing portion and a downstream space communicating to the introducing portion via the upstream space. When the engine is in a low engine load operation, the intake air mainly flows through the upstream space to an intercooler side via the baffle plate, and when the engine is in a high engine load operation, the intake air flows through the upstream and downstream spaces to the intercooler side via the baffle plate.
