Abstract:
1. A fuel injection controlling system of an internal combustion engine, comprising: an accelerator manipulator; an accelerator manipulated variable detection sensor configured to detect a manipulated variable of the accelerator manipulator; a rotation speed sensor configured to detect a rotation speed of the internal combustion engine; a throttle valve; a throttle valve drive motor configured to open and close the throttle valve in response to the manipulated variable of the accelerator manipulator; a throttle opening degree sensor configured to detect an opening degree of the throttle valve; and a controller configured to control the throttle valve drive motor and to compute basic injection time (Ti) of fuel, the controller comprising: wherein the controller is configured so that correction of the basic injection time by the corrector is performed with respect to the basic injection time (Ti) of the fuel computed by using the Ne—Th map, and wherein the controller is configured so that correction of the basic injection time by the corrector is not performed with respect to the basic injection time (Ti) of the fuel computed by using the Ne—Pb map.
