ABSTRACT:
A two-cycle engine has a scavenge pump provided in an intake passage, and a fuel injector provided for injecting fuel directly in a cylinder of the engine. A control unit has a calculator for producing a fuel injection pulse width signal. Engine speed at idling state is compared with a desired idle speed and an error signal is produced. The pulse width signal is corrected with a correction value based on the error signal so as to converge the idle speed to the desired idle speed.
