摘要： An internal combustion engine includes a main catalyst disposed in a main passage and a bypass catalyst disposed in a bypass passage bypassing the main passage on an upstream side of the main catalyst. The bypass passage has a smaller transverse cross-sectional area than the main passage. The internal combustion engine further includes a passage open/close unit, a residual gas amount changing unit, and a controller. The passage open/close unit is disposed in a portion of the main passage bypassed by the bypass passage to switch between an open state and a closed state. The residual gas amount changing unit is configured to change an amount of residual gas inside a combustion chamber. The controller is configured to control the residual gas amount changing unit when a passage opening condition for switching the passage open/close unit from the closed state to the open state is satisfied.
