摘要： An engine is operated in a homogeneous charge combustion mode or a stratified charge combustion mode. An intensive target throttle angle is computed based on the running state of the engine, regardless of a combustion mode which is underway. The intensive target throttle angle reflects an engine torque which is demanded at the time of executing the homogeneous charge combustion mode. At the time of executing the homogeneous charge combustion mode, the degree of opening of a throttle valve is adjusted based on the intensive target throttle angle to adjust the engine torque. At the time of executing the stratified charge combustion mode, a fuel injection amount is adjusted based on the intensive target throttle angle to adjust the engine torque. In other words, even in case where either of the two combustion modes is executed, the engine torque is adjusted based on the intensive target throttle angle. It is therefore possible to easily match engine torque characteristics between these different combustion modes.
摘要翻译：发动机以均匀充气燃烧模式或分层充气燃烧模式运行。不考虑正在进行的燃烧模式，基于发动机的运行状态来计算强化目标油门角度。强化目标油门角度反映了在执行均质充气燃烧模式时要求的发动机转矩。在执行均质充气燃烧模式时，基于强化的目标节气门角度来调节节气门的打开程度以调节发动机扭矩。在执行分层充气燃烧模式时，基于强化目标节气门角度来调整燃料喷射量，以调整发动机转矩。换句话说，即使在执行两种燃烧模式中的任一种的情况下，也可以基于强化的目标节气门角度来调整发动机转矩。因此，可以容易地匹配这些不同燃烧模式之间的发动机转矩特性。

摘要： A controller for an internal combustion engine that switches combustion modes in accordance with the running conditions of the engine. When there is a need to reduce the engine torque, the controller decreases the torque by a predetermined torque reduction method. The controller decreases the engine torque by a first torque reduction method when the engine is in a first combustion mode. When the engine is in a second combustion mode, the controller reduces the torque by a second torque reduction method. The controller sets a first control amount, which corresponds to the torque reduction requirement, according to one of the first and second torque reduction methods. The controller converts the first control amount into a second control amount, which corresponds to the other torque reduction method.

摘要： An engine can switch a combustion mode between homogeneous charge combustion and stratified charge combustion. The engine is controlled in accordance with a load acting on the engine. When homogeneous charge combustion is executed, an intake pressure, or a parameter representing the amount of intake air, is used as a value representing an engine load. When stratified charge combustion is executed, a value equivalent to the intake pressure presuming homogeneous charge combustion is executed with the amount of manipulation of an acceleration pedal at that time is computed as a virtual intake pressure, and the virtual intake pressure is used as a value representing the engine load. In either combustion mode, therefore, the intake pressure, or a common parameter, is used as a value representing the engine load to control the engine. This simplifies matching of engine power torques between both combustion modes.

摘要： A variable valve timing and lift mechanism includes an actuator that adjusts the period in which an intake valve is held open by moving a drive element. When a control unit switches the duration, the control unit controls the actuator so that the duration is changed at a first speed when the duration is equal to a first value, and at a second speed when the duration is equal to a second value that is smaller than the first value. The absolute value of the second speed is smaller than the absolute value of the first speed. In effect, the actuator is controlled so that when the duration is in a short-duration range, the duration changes more slowly than when the duration is in a long-duration range.

摘要： A failure diagnosis for a slide sensor of a variable valve mechanism is performed when a valve working angle is at a value in the initial state. The initial state is set to a valve characteristic state where the valve working angle is at the maximum value. The maximum valve working angle corresponds to the refuge running performable region in which an engine can be started and refuge running can be performed. Therefore, even when it is difficult to adjust the valve working angle using rotation of a spiral cam due to a failure in the slide sensor, the refuge running can be performed only by maintaining the initial state by maintaining control. It is thus possible to increase reliability of the refuge running in the case where a failure has occurred in the variable valve mechanism.
摘要翻译：当阀工作角度处于初始状态的值时，执行可变气门机构的滑动传感器的故障诊断。初始状态被设定为阀工作角为最大值的阀特性状态。最大阀工作角度对应于能够启动发动机并可进行避难运行的避难所运行区域。因此，即使由于滑动传感器的故障而难以通过螺旋凸轮的旋转来调节阀的工作角度，所以只能通过维持控制来维持初始状态来进行避难运行。因此，在可变气门机构发生故障的情况下，可以提高避难运行的可靠性。

摘要： An electronic control unit sets a target valve actuation parameter in accordance with an operating state of an internal combustion engine, and controls a variable valve actuation mechanism such that an actual valve actuation parameter of an intake valve becomes equal to the target valve actuation parameter. The variable valve actuation mechanism changes a valve actuation parameter of the intake valve. From before an initial fuel injection is performed to when a starting process of the engine is completed, the electronic control unit sets the target valve actuation parameter to an engine starting valve actuation parameter at which the valve closing timing of the intake valve coincides with or is close to a bottom dead center of the intake valve.

摘要： A device for controlling an internal combustion engine, comprising a variable valve mechanism for varying opening areas (valve lift) or the working angles (valve-opening periods) of at least either the intake valves or the exhaust valves, wherein a pressure in the cylinder is calculated based on the opening area or the working angle of at least either the intake valve or the exhaust valve varied by the variable valve mechanism, and the internal combustion engine is controlled based on the pressure in the cylinder. Upon calculating the pressure in the cylinder based on the opening areas or the working angles of the intake and exhaust valves, it is possible to more suitably control the internal combustion engine based not only upon the peak combustion pressure in the cylinder like when a combustion pressure sensor is used but also upon a pressure in the cylinder at a moment other than the peak combustion pressure.
