Abstract
A split engine operation of a multi-cylinder internal combustion engine having a closed loop or feed back control system is disclosed. At split engine operation mode, the feed back control will be suspended, and at full cylinder engine operation mode, the feed back control will be resumed. A relay is provided to suspend the supply of output from a PI detector to a fuel injection control unit. The relay is circuited with a cylinder selector unit via a counter so that the resumption of the supply of the output from the PI detector to the fuel injection control unit will take place when a predetermined time duration has past after the engine operating condition switched into full cylinder engine operation mode from split engine operation mode.
