    • In a control system for a valve actuation property variable control device which can switch over between a plurality of modes including a low speed mode for adapting at least one of an intake valve and an exhaust valve of an engine to a low speed range and a high speed mode for adapting the valve to a high speed range at least according to the rotational speed of the engine and a representative temperature of the engine, to prevent an abrupt change in the engine output by switching over valve actuating properties while the engine is being warmed up, the load condition of the engine is detected so that the transition from the low speed mode to the high speed mode may be prohibited if the representative temperature of the engine exceeds a prescribed level while a load higher than a prescribed level is being detected. Thereby, the driveability of the engine is improved.

    • A method of determining the activation of an exhaust gas ingredient-concentration sensor for use in an internal combustion engine. The air-fuel ratio of a mixture is controlled in a feedback manner by the use of a coefficient varying with an output of the sensor during engine operation in an air-fuel ratio feedback control region. The activation of the sensor is determined based on the output of the sensor. When the engine has shifted from the air-fuel ratio feedback control region to a predetermined decelerating region, calculated is an average value of values of the coefficient obtained by the feedback control immediately before the shifting. The air-fuel ratio of the mixture is leaned by the use of the average value thus calculated. It is determined whether or not the sensor is activated when the air-fuel ratio has thus been leaned.
    • 一种确定用于内燃机的排气成分浓度传感器的活化的方法。 混合物的空燃比通过在发动机运转中在空燃比反馈控制区域中使用随传感器的输出变化的系数以反馈方式进行控制。 基于传感器的输出确定传感器的激活。 当发动机已经从空燃比反馈控制区域转移到预定减速区域时,计算出通过紧接变速前的反馈控制获得的系数的值的平均值。 混合物的空燃比利用这样计算的平均值倾斜。 当空燃比因此倾斜时,确定传感器是否被激活。

    • A knocking control apparatus for a variable cylinder internal combustion engine avoids erroneous determination of knocking during a fault in a cylinder pausing mechanism to appropriately control knocking associated with the ignition timing, thereby preventing engine stall and reducing a deterioration in a catalyst. The variable cylinder internal combustion engine can be switched between a full cylinder operation mode in which all of a plurality of cylinders are operated, and a partial cylinder operation mode in which part of the plurality of cylinders is paused by a cylinder pausing mechanism. The knocking control apparatus comprises a knocking sensor for detecting knocking of the variable cylinder internal combustion engine, and an ECU for performing a knocking control to correct an ignition timing toward a retarding side when knocking is detected, determining whether or not the cylinder pausing mechanism fails, and suspending the knocking control when the fault determining means determines that the cylinder pausing mechanism is determined to fail.
