    Abstract: An electronic control unit for an internal combustion engine that includes an engine-driven alternator 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 charged with electric power generated by the alternator is higher than or equal to a predetermined value, charging control for setting a voltage generated by the alternator at a voltage lower than a normal generated voltage is executed. When the state of charge of the battery is higher than or equal to the predetermined value, charging control for charging the battery at the voltage is prohibited when a degree of mixing of fuel in lubricating oil of the internal combustion engine is higher than or equal to a predetermined degree.

    Abstract: A fuel injection control apparatus for a direct injection type internal combustion engine according to the invention includes a control unit. The control unit estimates the degree to which lubricating oil, which is used in the internal combustion engine, has been diluted with fuel based on the length of time the internal combustion engine has been running, and an accumulated value that indicates an amount of air that has been taken in by the internal combustion engine while the internal combustion engine has been running or an accumulated value that indicates an amount of fuel that has been injected while the internal combustion engine has been running. The control unit determines the amount of fuel to be injected based on the degree of dilution.

    Abstract: A controller for controlling a valve timing of an engine that calculates a duty correction value using an arithmetic expression reflecting a physical model, which is associated with torque applied to an exhaust valve camshaft, a spring force exerted by an advancing spring for varying a rotational phase of the exhaust valve camshaft, and hydraulic pressure of operating oil. When the coolant temperature is lower than 80° C., the controller sets the duty correction value to zero. The duty correction value reflecting all the fluctuation factors of the engine is easily obtained without using a map requiring a large amount of data.

    Abstract: A controller for controlling valve timing imbalance between cylinder groups of an engine. For each cylinder group, the controller has a variable mechanism for varying the valve timing. A lock mechanism locks the variable mechanism so as to maintain the valve timing of the cylinder group at a lock value. An ECU sets a valve timing target value based on the operating condition of the engine. The ECU and an oil control valve drive the variable mechanism. The ECU restricts the valve timing target value of at least one of the variable mechanisms of which operation is unlocked when the operation of at least one of the variable mechanisms is locked so that difference between the target value and the lock value decreases.

    Abstract: In a vehicle having mounted therein an engine including an injector that directly injects fuel into a cylinder, in the case in which a warm-up control required condition is established, catalyst warm-up control is executed if an amount of fuel diluted in oil is low, or even if the amount of fuel diluted in oil is high, when the temperature of the engine oil is less than the fuel volatilization temperature. In contrast, even in the case in which the warm-up control required condition is established, if the amount of fuel diluted in oil is greater than or equal to a determination value, and furthermore the temperature of the engine oil is greater than or equal to the fuel volatilization temperature, there is the possibility of negative influence on exhaust emissions, and therefore the catalyst warm-up control is prohibited.

    Abstract: 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.
