Control Device Of Internal Combustion Engine For Portable Work Machine, And Portable Work Machine

Abstract

A control device of an internal combustion engine for a portable work machine is provided that can suppress overspeed of the engine. The control device of the internal combustion engine for the portable work machine performs control of the internal combustion engine of the portable work machine, the portable work machine including the internal combustion engine including a combustion chamber, an ignition plug that ignites an air-fuel mixture supplied to the combustion chamber, and a crankshaft as an output shaft. When the rotational speed of the crankshaft reaches the predetermined target rotational speed, the control device performs ATDC switching control in which an ignition timing of the ignition plug is switched from a timing before top dead center to a timing after the top dead center, and skip-fire control in which the number of ignitions of the ignition plug per rotation is reduced.
