ABSTRACT:
A system and method for controlling an engine, in which a value correlative to an engine output is detected, a target value of the engine output correlative value is calculated on the basis of an angular displacement of an accelerator pedal and engine speed, the detected value correlative to the engine output is compared with the target value, an opening angle of a throttle valve located within a throttle chamber of the engine for adjusting an intake air quantity supplied to the engine according to its opening angle is calculated on the basis of the comparison result, and the throttle valve is actuated to adjust the intake air quantity according to the calculated opening angle so that the detected value correlative to the engine output coincides with the target value.
