Abstract:
1. An engine control apparatus comprising: an engine having an intake air duct; an intake air flow control valve provided in the intake air duct of the engine, and configured to adjust an amount of intake air supplied to the engine; an engine speed sensor configured to detect a engine speed of the engine; a temperature sensor configured to detect a warm-up state of the engine; and a control unit configured to: wherein the control unit performs the feedback control based on the second amount of intake air until the engine speed reaches the target warm idle speed, and then controls the intake air flow control valve to supply a predetermined amount of intake air which is less than the second amount of intake air for a predetermined period until the engine speed exceeds the target warm idle speed, and then performs the feedback control based on the first amount of intake air, wherein the control unit is operable to determine whether or not conditions of execution of the idle feedback control are satisfied and execute the feedback control, and the conditions of execution of the idle feedback control are satisfied when a transmission connected to the engine is in a neutral state, a throttle grip which is operable to increase the engine speed is not operated by an operator, and the engine speed and the opening of the intake air flow control valve are within an idle feedback control region.
