摘要： An ECU for controlling an engine counts an unused time TIM of engine in a low-temperature environment. If the unused time TIM is shorter than a predetermined reference value, the ECU sets idle speed immediately after start of operation of the engine to a first idle speed, and if the unused time TIM is longer than the reference value, sets the idle speed to a second idle speed higher than the first idle speed. If duration of the second idle speed exceeds a reference period determined by state of driving of the vehicle, the ECU sets the idle speed to be lower than the second idle speed. In this manner, increased vibration in idling operation in a low-temperature environment can be prevented.
摘要翻译：用于控制发动机的ECU在低温环境中计算发动机的未使用时间TIM。如果未使用时间TIM比规定的基准值短，则ECU将发动机起动后立即空转至第一空转速度，如果未使用时间TIM比基准值长，则将空转速度设定为第二空转速度高于第一怠速。如果第二空转速度的持续时间超过由车辆的驱动状态决定的基准时间段，则ECU将怠速设定为低于第二空转速度。以这种方式，可以防止在低温环境中的空转操作中增加的振动。

摘要： An ECU for controlling an engine counts the continued period of stopping the engine in a low-temperature environment. The ECU sets the idle rotational speed at a first idle rotational speed when the stopped period is below a predetermined threshold value, and at a second idle rotational speed higher than the first idle rotational speed when the stopped period exceeds the reference value. Accordingly, resonance at the driving force transmission system during idle operation can be prevented even in the case where a mount employed for attaching the engine to the vehicle is hardened as a result of undergoing a low-temperature environment for a long period of time, and the resonant rotational speed of the driving force transmission system including the engine varies.
摘要翻译：用于控制发动机的ECU计算在低温环境中停止发动机的持续时间。当停止时段低于预定阈值时，ECU将怠速旋转速度设定在第一空转速度，当停止时间超过参考值时，将其设定为高于第一怠速转动速度的第二空转转速。因此，即使在用于将发动机安装到车辆上的安装座由于经受长时间的低温环境而硬化的情况下也能够防止怠速运转期间的驱动力传递系统的共振，并且包括发动机的驱动力传递系统的共振转速变化。

摘要： Disclosed is a control device applied to an internal combustion engine provided with a fuel vapor treatment system for treating collected fuel vapor by purging the collected fuel vapor into intake air downstream from an air flowmeter (6) and an exhaust gas recirculation system for recirculating part of exhaust gas in the intake air using intake negative pressure. An electronic control unit (22) performs an advance correction corresponding to the exhaust gas recirculation quantity regarding the MBT ignition timing and the knock limit ignition timing, and corrects the volumetric efficiency of the internal combustion engine, which is used for the calculation of the advance correction quantity used for the advance correction, according to the purge air quantity. Consequently, regardless of the decrease of the exhaust gas recirculation quantity caused by the implementation of a large quantity of purge, the appropriate advance corrections of the MBT ignition timing and the knock limit ignition timing become possible.

摘要： An inter-cylinder air-fuel ratio imbalance abnormality detection apparatus includes an air-fuel ratio sensor disposed in an exhaust passage of a multi-cylinder internal combustion engine, and an abnormality detection unit that detects an inter-cylinder air-fuel ratio imbalance abnormality on the basis of a degree of variation in an output of the air-fuel ratio sensor. The abnormality detection unit detects the inter-cylinder air-fuel ratio imbalance abnormality by comparing a value of a parameter that correlates with the degree of variation in the output of the air-fuel ratio sensor with a predetermined abnormality determination value. The abnormality determination value is set individually for each of a plurality of preset operating regions of the internal combustion engine.
