    • An engine controller performs low opening degree control during a first intake stroke period since an engine start is commenced until first intake strokes of respective cylinders end. Thus, an opening degree of an intake throttle valve is controlled to a fully closed position or proximity of the fully closed position such that intake pressure downstream of the intake throttle valve becomes equal to or lower than critical pressure with respect to intake pressure upstream of the intake throttle valve during an intake stroke of each cylinder. The controller calculates a leak air quantity at the time when the intake throttle valve is fully closed based on an intake air quantity sensed during the low opening degree control. The controller corrects a feedback gain of idle speed control in accordance with the leak air quantity of the intake throttle valve.
    • 发动机控制器在第一进气冲程期间执行低开度控制,因为从开始发动机起动直到各气缸的第一进气冲程结束为止。 因此,将进气节流阀的开度控制在完全关闭位置或完全关闭位置附近,使得进气节流阀下游的进气压力相对于上游的进气压力等于或低于临界压力 在每个气缸的进气冲程期间进气节流阀。 控制器基于在低开度控制期间感测到的进气量计算进气节流阀完全关闭时的泄漏空气量。 控制器根据进气节流阀的泄漏空气量来校正怠速控制的反馈增益。

    • An air-intake device includes a throttle valve pivotally movable around a shaft connected to one end of the throttle valve and an airflow passage formed in the intake air passage above an upper end of the throttle valve. In a region where an amount of intake air is small (i.e., in a region where an opening-degree of the throttle valve is small), an amount of intake air passing through the airflow passage is precisely controlled. In the same region, a high-speed airflow is generated in the airflow passage thereby to formulate a uniform air-fuel mixture in a combustion chamber of an internal combustion engine. These functions are easily realized by simply adding a member for forming the airflow passage to a throttle valve unit disposed in the intake air passage.
    • 进气装置包括可围绕连接到节流阀的一端的轴可枢转地运动的节流阀和形成在进气通道中的节气门上端之上的气流通道。 在进气量少的区域(即在节流阀的开度小的区域),能够精确地控制通过气流通道的吸入空气量。 在相同的区域中,在气流通道中产生高速气流,从而在内燃机的燃烧室中配置均匀的空气 - 燃料混合物。 这些功能通过简单地将用于形成气流通道的构件添加到设置在进气通道中的节气门单元来容易地实现。

    • An intake throttle valve is located in an intake passage upstream of first and second intake ports, such that intake air flows into mainly the first intake port to generate a swirl flow when an opening degree of the intake throttle valve is not larger than a predetermined value, and flows into both the first and second intake ports when the opening degree thereof is larger than the predetermined value. Furthermore, first and second fuel injection valves for respectively injecting fuel to the first and second intake ports are controlled to inject fuel from the first fuel injection valve when the opening degree of the intake throttle valve is not larger than about the predetermined value, and to inject fuel from both the first fuel injection valve and the second fuel injection valve when the opening degree of the intake throttle valve is larger than about the predetermined value.
