Abstract
A split engine comprising a plurality of cylinders which are divided into a first cylinder group and a second cylinder group. The second cylinder group is connected to the outside air via a second intake passage. The first cylinder group is connected to a first intake passage which is, in turn, connected to the second intake passage via a shut-off valve. The first intake passage is connected to the exhaust passage of the engine via an exhaust-gas recirculation passage. When the level of the load of the engine becomes high, the exhaust-gas recirculation passage is shut off, and the shut-off valve is initially opened at a high speed and then opened at a low speed.
