ABSTRACT:
The fuel supply to an internal combustion engine is decreased when the engine is in an operating region wherein the intake passage pressure is lower than a first predetermined value. The first predetermined value is corrected in response to detected atmospheric pressure encompassing the engine. Further, the fuel supply to the engine is interrupted when the engine is in a second operating region wherein the intake passage pressure is lower than a second predetermined value, which is lower than the first predetermined value. The second predetermined value is corrected in response to the detected atmospheric pressure, together with the first predetermined value.
