    • A method for controlling the rotational speed of an internal combustion engine in the idling state, including the steps of detecting an intake air flow rate in the engine and an air-fuel ratio of the engine and supplying the results of the decisions to a control circuit. The method includes the steps of generating output signals from the control circuit for generating the air flow rate and fuel injection amount, regulating the air flow rate while the engine is in an idling state, and regulating the fuel injection amount from a fuel injector in the engine. The method further includes the step of regulating the air flow rate while the engine is in an idling state and regulating the fuel injection amount from a fuel injector. The generation of the output signals from the control circuit is carried out by the steps of calculating an instruction output of the fuel injection amount, obtaining an air-fuel ratio closed-loop correction value, carrying out learning control for an air-fuel ratio learning correction value, deciding whether or not the engine is running under low atmospheric pressure on the basis of a comparison between the air fuel ratio learning correction value and a predetermined value, and changing the intake air flow rate for the idling state from the decision.
    • 一种用于控制处于怠速状态的内燃机的转速的方法,包括以下步骤:检测发动机中的进气流量和发动机的空燃比,并将决定结果提供给控制电路 。 该方法包括以下步骤:产生来自控制电路的输出信号,用于产生空气流量和燃料喷射量,在发动机处于怠速状态时调节空气流量;以及调节来自燃料喷射器的燃料喷射量 发动机。 该方法还包括在发动机处于怠速状态时调节空气流量并且调节来自燃料喷射器的燃料喷射量的步骤。 通过以下步骤来执行来自控制电路的输出信号的产生:计算燃料喷射量的指令输出,获得空燃比闭环校正值,执行空燃比学习的学习控制 校正值,基于空燃比学习校正值和预定值之间的比较,判定发动机是否在低气压下运行,以及根据该判定改变空转状态的进气流量。

    • A valve timing control apparatus is provided with at least one of: an advance-angle control starting device configured to start to control a relative rotational phase of a camshaft with respect to a crankshaft to an advance side when an internal combustion engine starts and when a valve lift amount associated with an intake valve or an exhaust valve increases; and a delay-angle control starting device configured to start to control the relative rotational phase to a delay side when the internal combustion engine starts and when the valve lift amount associated with the intake valve or the exhaust valve decreases. It is possible to appropriately release engagement by a locking mechanism between a first rotating body configured to rotate synchronously with the camshaft and a second rotating body configured to rotate synchronously with the crankshaft.
