摘要： The engine ECU executes a program including the step (S320) of setting an upper limit guard value of a fuel pressure by executing low fuel pressure control in the case where a low fuel pressure control execution condition is satisfied with fulfillment of conditions that execution of the low fuel pressure control is permitted, that engine speed NE is lower than a threshold value, and that the atmospheric pressure is higher than a threshold value (YES in S310), and the step (S330) of controlling the fuel pressure to be a target fuel pressure within a range not exceeding the upper limit guard value. In the state where the engine load factor is greater than a threshold value, if rich determination is ON as the correction amount for decreasing the fuel injection amount in the high load region is greater than a threshold value, the low fuel pressure control is permitted.

摘要： An internal combustion engine has a fuel injection valve. To cause an actual air-fuel ratio of air-fuel mixture burned in the engine to be equal to a target value, an electronic control device corrects a fuel injection amount from the fuel injection valve using a feedback correction value. The feedback correction value is changed based on the actual air-fuel ratio. The electronic control device computes, as a safeguard value, a value of the feedback correction value that causes a fuel injection time, which is an instruction sent to the fuel injection valve, to be a permissible minimum time. When the fuel injection time is less than the permissible minimum time, the electronic control device limits the lowest value of the feedback correction value to the safeguard value. As a result, the actual air-fuel ratio is prevented from being rich.
摘要翻译：内燃机具有燃料喷射阀。为了使发动机中燃烧的空气燃料混合物的实际空燃比等于目标值，电子控制装置使用反馈校正值来校正来自燃料喷射阀的燃料喷射量。反馈校正值根据实际的空燃比而变化。电子控制装置将作为发送到燃料喷射阀的指示的燃料喷射时间的反馈修正值的值作为保护值计算为允许的最小时间。当燃料喷射时间小于允许的最小时间时，电子控制装置将反馈校正值的最低值限制为保护值。结果，防止实际的空燃比浓。

摘要： Either associated process control or discrete process control is selected for valve timing control according to the engine operation state. Under the associated process control, the target displacement angle INP of an intake camshaft (22, fig. 2) is computed according to the engine operation state, and the actual displacement angle INR of the camshaft (22, fig. 2) is brought closer to it. Further, based on the target valve overlap amount OVP computed according to the engine operation state and the actual displacement angle INR, the target displacement angle EXP of an exhaust camshaft (23, fig. 2) is computed, and the actual displacement angle EXR of the camshaft (23, fig. 2) is brought closer to it. Under the discrete process control, the target displacement angles INP, EXP are computed according to the engine operation state, and the actual displacement angles INR, EXR are brought closer to them.

摘要： An electronic control unit (60) for an internal combustion engine (10) that includes an engine-driven alternator (70) diagnoses on the bases of an air-fuel ratio correction amount in air-fuel ratio feedback control whether a rich abnormality that the air-fuel ratio of air-fuel mixture is excessively rich is occurring in a fuel injection system. When the state of charge of a battery (80) charged with electric power generated by the alternator (70) is higher than or equal to a predetermined value, charging control for setting a voltage generated by the alternator (70) at a voltage (V2) lower than a normal generated voltage is executed. When the state of charge of the battery (80) is higher than or equal to the predetermined value, charging control for charging the battery (80) at the voltage (V2) is prohibited when a degree of mixing of fuel in lubricating oil of the internal combustion engine (10) is higher than or equal to a predetermined degree.

摘要： A controller of an internal combustion engine that performs catalyst warm-up control to promote warm-up of an exhaust purification catalyst is provided. The controller carries out the catalyst warm-up control by retarding the ignition timing after increasing the throttle opening degree when a prescribed performing condition is satisfied. The controller corrects the fuel injection amount to an increased value in the period from when the performing condition is met to when the ignition timing is retarded.
