A control device of an engine having cylinders which are divided into two cylinder groups. The first cylinder group is provided with a first throttle valve and a first recirculation valve. The second cylinder group is provided with a second throttle valve and a second recirculation valve. When shifting from full cylinder operation to partial cylinder operation where the second cylinder group is left idle, the sum of the load of both the cylinder groups is maintained as substantially the same load as the total load before shifting to the partial cylinder operation, the first throttle valve is gradually opened, and the second throttle valve is gradually closed.
