An engine control device with a reverse control function including: reverse control means for performing reverse control including a process of excessively advancing an ignition position of an engine for reversing a rotational direction of the engine when a reverse switch is operated; and a light emitting display device that displays that the reverse control is performed, wherein the reverse control means further includes light emitting display device blinking means for blinking the light emitting display device when the reverse switch is once operated, and operating error preventing means for starting the reverse control when the reverse switch is again operated within a set time after the one operation of the reverse switch, and stopping the reverse control when the reverse switch is not again operated within the set time after the one operation of the reverse switch.

Engine control device with reverse control function

A control system for a reversible internal combustion engine comprising an AC magneto generator to generate an AC output voltage and a signal generator to generate pulse signals of polarity different from each other with a relation between the phases of the AC output and the pulse signals set so that the half waves of the output voltage having the same polarity when the two pulse signals of different polarities are generated whereby the rotational direction of the engine is judged from the polarity of the half wave of the output voltage of the magneto generator when the signal generator generates the pulse signal of either polarity and the engine is ignited at the low speed ignition position after it is confirmed that the rotational direction of the engine is reversed.
