Document Type and Number:
Japanese Patent JP3289277
Kind Code:
B2
Abstract:
An engine speed control apparatus having an auxiliary air amount controller is disclosed. The apparatus has an actuator (15) which is attached to an engine intake manifold (18) so as to bypass a throttle valve (12) and controls a flow rate of an auxiliary air and a control unit (50) for driving the actuator. The control unit (50) detects whether an engine (10) is in an idling state or not on the basis of a combination of an engine rotational speed and other information. When the idling state is detected, a target value of an intake pressure on the downstream side of the throttle valve (12) is set in accordance with the engine speed at that time. The control unit (50) drives and controls the actuator so that the actual intake pressure coincides with the target value. Thus, when the operating mode of the engine (10) is shifted from the non-idling state to the idling state, an air amount which is required by the engine (10) can be accurately supplied and the engine speed can be rapidly converged to the target value.
