ABSTRACT:
An RPM control apparatus for an internal combustion engine including a first limiter which suppresses an RPM feedback control signal indicating a target suction quantity or a target suction pipe pressure within a predetermined range that is set necessary and sufficient for covering a fluctuation range attributed to a no-load loss of the engine, and a second limiter which suppresses a suction feedback control signal on the basis of the output of the first limiter and an actual suction air quantity or suction pipe pressure within a predetermined range that is set necessary and sufficient for covering a fluctuation range attributed to the density of suction air, etc.
