ABSTRACT:
An apparatus for controlling the speed of a direct fuel injected, scavenged, two-stroke engine comprises a first sensor for sensing the degree to which the throttle is open, means for sensing whether the intake air amount is in the air-excess range, means for sensing whether the degree to whcih the throttle is open has been substantially constant for a predetermined amount of time, a sensor for sensing the engine revolution speed, means for producing a desired engine revolution speed based on the degree to which the throttle is open, and means for producing a signal coresponding to the difference between the engine revolution speed and the desired engine speed, when the degree to which the throttle is open has been substantially constant for the predetermined amount of time. A control device adjusts an engine running parameter based on this difference, to reduce this difference.
