Abstract
A fuel injection control system makes it possible to obtain an output of a lean combustion type engine through an easy operation, even in a throttle opening region of greater than a lean limit. A throttle valve is configured to be turnable up to an over-fully opened position, which is greater than a fully opened position that corresponds to a maximum air flow rate, where the air flow rate is not substantially varied from the maximum air flow rate. In a region where the throttle valve is operated to or above the fully opened position when under a high load, the fuel-air mixture is enriched and a high output is obtained by controlling the throttle opening through operating only a power lever.
