PROBLEM TO BE SOLVED: To provide an electronic control device that can attain an inexpensive general-purpose engine capable of improving fuel economy and reducing a regulated substance amount in exhaust gas, while performing feedback control in which atmospheric pressure is reflected with a simple structure.SOLUTION: In an electronic control device 100, a fuel injection amount calculation unit 108 calculates a basic fuel injection amount regulated according to an engine rotational frequency, in a case where a highland switch 33 is in an on state, with an oxygen concentration feedback coefficient calculated according to oxygen concentration detected by an oxygen concentration sensor 30 and a first correction coefficient correcting the basic fuel injection amount to one for highland correspondingly to the on state of the highland switch 33.SELECTED DRAWING: Figure 1 |
