    • A control device for a spark-ignition internal combustion engine that sets ignition timing based on a target value of a predetermined combustion-related parameter correlated with a combustion state and operates an ignition device in accordance with the ignition timing thus set. The control device calculates an actual value of the combustion-related parameter from an output value of the cylinder pressure sensor and feeds back the calculated value of the combustion-related parameter to the setting of ignition timing. Further, in parallel with the above processing, the control device calculates a value of a predetermined combustion variation parameter correlated with the magnitude of combustion variation from the output value of the cylinder pressure sensor. If the calculated value of the combustion variation parameter deviates from an allowable range of the combustion variation, the control device stops the feedback of the calculated value of the combustion-related parameter.
    • 一种用于火花点火内燃机的控制装置,其基于与燃烧状态相关的预定燃烧相关参数的目标值来设定点火正时,并根据如此设定的点火正时来操作点火装置。 控制装置根据气缸压力传感器的输出值计算燃烧相关参数的实际值,并将燃烧相关参数的计算值反馈到点火正时的设定。 此外,与上述处理同时,控制装置根据气缸压力传感器的输出值计算与燃烧变化量相关的预定燃烧变化参数的值。 如果燃烧变化参数的计算值偏离燃烧变化的允许范围,则控制装置停止对燃烧相关参数的计算值的反馈。

    • A control apparatus for an internal combustion engine that accurately incorporates demands related to various capabilities of the internal combustion engine. A demand output unit outputs various capability demands of the internal combustion engine, expressed in terms of either torque, efficiency, or an air-fuel ratio data. A torque mediation unit collects only the demand values expressed in terms of torque, and mediates the torque demand values into one. An efficiency mediation unit collects the demand values expressed in terms of efficiency and mediates the efficiency demand values into one. An air-fuel ratio mediation unit collects the demand values expressed in terms of the air-fuel ratio and mediates the air-fuel ratio demand values into one. A control variable computing unit computes control variables of actuators, based upon the torque demand value, efficiency demand value, and air-fuel ratio demand value output from the mediation units.
    • 一种用于内燃机的控制装置,其精确地包括与内燃机的各种能力有关的要求。 需求输出单元输出内燃机的各种能力要求,以扭矩,效率或空燃比数据表示。 扭矩调节单元仅收集以扭矩表示的需求值,并将扭矩需求值调解为一个。 效率调解单位收集以效率表达的需求价值,并将效率需求值纳入一体。 空燃比调节单元收集以空燃比表示的需求值,并将空燃比要求值调节为1。 控制变量计算单元基于从中介单元输出的扭矩需求值,效率需求值和空燃比要求值来计算执行器的控制变量。
