る気筒数制御エンジン。It is equipped with a dormant cylinder that stops operating when the fuel supply is cut off in the light load range of the engine, and an active cylinder that is always activated. In a multi-cylinder engine which is divided downstream into an intake passage on the idle side and an intake passage on the active side, and is provided with a cutoff valve that closes the upstream part of the intake passage on the idle side when the cylinder is inactive, the intake passage is throttled downstream of the cutoff valve. Directing fresh air by bypassing the valve (forming a fresh air supply passage and an exhaust recirculation passage that distributes and recirculates a part of the engine exhaust through branch passages to the working side intake passage and the idle side intake passage, respectively) , integrally includes a valve means that closes the fresh air supply passage when the cylinder is in operation and opens both branch passages, and closes the branch passage on the inactive side when the cylinder is inactive and opens the fresh air supply passage by a predetermined amount in accordance with the rotational speed of the engine. An engine with controlled number of cylinders.
