    Patent number: 5540633
    Abstract: A control device for a variable displacement engine, coupled with an automatic transmission, for an automobile, wherein the control device controls cylinders depending on the driving condition. The control device changes working cylinders without changing the number of working cylinders during the shift operation of the automatic transmission by detecting that the automatic transmission is going to shift. When the control device changes working cylinders without changing the number of working cylinders, the control device controls cylinders so that cylinders which are non-working before the changing work after the changing, and controls cylinders so that a non-working cylinder is not followed by another non-working cylinder in the firing order of the case of all cylinders are working.
