    • An air-fuel ratio control system for an internal combustion engine has an air-fuel ratio sensor arranged in an exhaust passage of the engine for detecting an air-fuel ratio of exhaust gases emitted from a plurality of cylinders. An output from the air-fuel ratio sensor is sampled whenever the engine rotates through a predetermined crank angle, and sampled values of the output from the air-fuel ratio sensor are sequentially stored. An output characteristic of the air-fuel ratio sensor is detected. One of the sampled values of the output from the air-fuel ratio sensor is selected at least depending on the output characteristic of the air-fuel ratio sensor. An air-fuel ratio of a mixture supplied to each of the cylinders is estimated, separately from other ones of the cylinders, based on selected ones of the sampled values of the output from the air-fuel ratio sensor and a model representative of a behavior of the exhaust passage. The air-fuel ratio of the mixture supplied to the each of the cylinders is controlled in a feedback manner responsive to the estimated air-fuel ratio of the mixture such that the estimated air-fuel ratio of the mixture supplied to the each of the cylinders is converged to a desired air-fuel ratio.
    • 用于内燃机的空燃比控制系统具有布置在发动机的排气通道中的空燃比传感器,用于检测从多个气缸排出的废气的空燃比。 每当发动机旋转预定的曲柄角时,对空燃比传感器的输出进行采样,依次存储来自空燃比传感器的输出的采样值。 检测空燃比传感器的输出特性。 至少根据空燃比传感器的输出特性来选择空燃比传感器的输出的取样值之一。 基于来自空燃比传感器的输出的取样值和代表行为的模型中的选定的一个来估计提供给每个气缸的混合物的空燃比与其它气缸分开地估计 的排气通道。 供给到每个气缸的混合物的空燃比以响应于混合物的估计空燃比的反馈方式进行控制,使得供给到每个气缸的混合物的估计空燃比 收敛到期望的空燃比。

    • A system for controlling an air/fuel ratio for an internal combustion engine, using an oxygen concentration sensor having a first chamber for introducing therein exhaust gas of the engine and a second chamber for introducing therein reference ambient air to detect oxygen content in the exhaust gas. In order to eliminate exhaust gas pulsation which could affect on detection accuracy, it is firstly determined if engine operation is in a transient state or in a normal state. Then the detected oxygen concentration value in the preceding cycle is added to the product obtained by multiplying the deviation between the values in the preceding and current cycles by a coefficient .alpha.. The coefficient is made different in the transient state and in the normal state. In the normal engine operation state, the coefficient .alpha. is determined from engine speed and load.
    • 一种用于控制内燃机的空燃比的系统,其使用具有用于在其中引入发动机的排气的第一室的氧浓度传感器和用于在其中引入参考环境空气的第二室,以检测废气中的氧含量 。 为了消除可能影响检测精度的废气脉动,首先确定发动机运转是处于过渡状态还是处于正常状态。 然后,将前一周期中检测到的氧浓度值加到通过将前一周期和当前周期中的值之间的偏差乘以系数α而获得的乘积。 系数在过渡状态和正常状态下不同。 在正常发动机运转状态下,根据发动机转速和负荷确定系数α。

    • According to one embodiment, an information processor includes an optical disc drive, an acquiring module, a storage module, and a determination module. The acquiring module acquires identification information that uniquely identifies an optical disc loaded in the optical disc drive based on information read from the optical disc. The storage module obtains information related to failure analysis of the optical disc contained in state information indicating reading state or writing state upon reading from or writing to the optical disc, and stores the information related to failure analysis in association with the identification information. The determination module calculates values each indicating a level of failure of the optical disc based on pieces of information related to failure analysis of the optical disc stored until just recently in association with the identification information and, when the values satisfy a predetermined condition, determines that there is a risk of failure in the optical disc.
