Abstract
In a V type engine comprising a catalyst in each of banks, when a fuel cut requirement on the basis of a traction control is generated, cylinders in which the fuel is cut are controlled to be switched between right and left banks. For example, when a requirement for a fuel cut with respect to two cylinders, at first, after the fuel cut of two cylinders are performed in the right bank for a predetermined time, the fuel cut of two cylinder are performed in the left bank for a predetermined time and this operation is repeated during a continuing time of the fuel cut. Accordingly, a thermal damage due to the fuel cut can be prevented from concentrating only to one catalyst.
