  "textContent": "An internal combustion engine () is provided with a turbocharger (), and is configured to be switchable between a stoichiometric combustion mode having a theoretical air-fuel ratio as a target air-fuel ratio and a lean combustion mode having a lean air-fuel ratio as a target air-fuel ratio. An air bypass valve () is provided in an air bypass passage () communicating a collector () on the downstream of a throttle valve () with the upstream side of a compressor () in an intake passage (). At the time of the shifting from the lean combustion mode to the stoichiometric mode, the throttle valve () is closed and the air bypass valve () is temporarily opened to decrease the pressure inside the collector () quickly.",
