Abstract
In a system for controlling a general-purpose air-cooled internal combustion engine having two cylinders each equipped with a throttle valve and a fuel injector, and a cooling fan that selectively directs air onto the cylinders, a throttle driver selectively drives the respective throttle valve of each cylinder to open or close. The system also includes an injector driver that selectively drives the respective injector of each cylinder to open, and a controller that controls operation of the throttle driver and injector driver in such a way that the throttle opening and an amount of fuel to be injected are different for each cylinder, such that an engine speed becomes substantially constant, thereby enabling the engine to obtain desired output characteristics.
