Claim Text:
1. A fuel injection control system comprising: an engine speed detector configured to detect an engine speed (NE); a throttle opening degree detector configured to detect a throttle opening degree (TH); a fuel injection device configured to inject fuel; a fuel injection controller configured to calculate, based on an injection amount map, a fuel injection amount of the fuel to be injected from the fuel injection device and configured to control the fuel injection device to inject the fuel according to the calculated fuel injection amount; a fuel injection number determining device configured to determine based on the throttle opening degree (TH) detected by the throttle opening degree detector and the engine speed (NE) detected by the engine speed detector whether a frequency of fuel injections during one cycle of an engine is to be one or two, the one cycle of the engine having a predetermined number of divided injection stages including a first predetermined injection stage, a second predetermined injection stage after the first predetermined injection stage, and a third predetermined injection stage; and a fuel injection mode setting device, the fuel injection controller being configured to control the fuel injection device according to the fuel injection mode set by the fuel injection mode setting device.
