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.

摘要： In an estimation apparatus of an air intake flow for an internal combustion engine, an air intake flow rate fed into a portion just upstream of an intake valve at a predetermined timing before starting of fuel injection is calculated based on an output of an air flow meter. A variance in the air intake flow rate caused by the change in the intake pressure at the portion just upstream of the intake vale at the predetermined timing is calculated based on an output of a pressure sensor. The calculated air intake flow rate is added to the variance to obtain an air intake flow rate fed into a cylinder at the predetermined timing. The air intake flow rate fed into the cylinder is corrected to an air intake flow rate required for estimating an actual air intake flow based on an amount of change in the air intake flow rate fed into the cylinder at the predetermined timing.

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 direct-injection internal combustion engine can smoothly switch and transition between a first operation mode and a second operation mode according to an operating condition of the engine. An engine control amount in the first operation mode is calculated differently from an engine control amount in the second operation mode. However, even if the engine control amount requires correction only in the second operation mode, calculation of a correction amount is made during the first operation mode as well. During a transition from the first operation mode to the second operation mode, the correction amount calculated during the first operation mode is taken into account in calculating an engine control amount. As the correction amount is already available at the time of transition, a suitable engine control amount can be immediately obtained.

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 internal combustion engine includes a valve timing change mechanism that changes the phase of an intake cam, and a lift amount change mechanism that changes lift amount by causing displacement of a control shaft. An electronic control unit performs a coordinated control in which the lift amount change mechanism is operated such that the position of the control shaft that is detected by a position detection sensor becomes the target position, and the valve timing change mechanism is operated according to a control state of the lift amount change mechanism. When a discrepancy between the actual position of the control shaft and the detected position thereof is estimated to be large, coordinated control is forbidden and the valve timing change mechanism is operated based on engine load.
