摘要： The present invention has an object to enable a torque as required to be realized without being influenced by an operation state of an IN-VVT, which is a variable valve timing mechanism which changes a valve timing of an intake valve. For this purpose, a control device for an internal combustion engine provided by the present invention stores data that defines a relationship between an air quantity and a torque in an MBT in association with the operation state of the IN-VVT, and calculates a target air quantity for realizing a required torque based on the data. The control device calculates an actual air quantity which is actually realized by an operation of a throttle when operating the throttle to realize the target air quantity. Further, the control device for an internal combustion engine provided by the present invention stores data that defines a relationship of the air quantity and an ignition timing in a case in which the IN-VVT is in a maximum retardation position, and calculates a basic ignition timing from the actual air quantity based on the data. Further, the control device for an internal combustion engine provided by the present invention determines an advance correction amount of the ignition timing from the operation state of the IN-VVT. The control device determines a final ignition timing from the basic ignition timing and the advance correction amount.

摘要： A control apparatus for a cylinder injection type internal combustion engine in which the fuel injection mode of the engine is switched between a compression stroke injection and an intake stroke injection. When the engine is cold, the compression stroke injection is selected for the fuel injection mode so that injected fuel collides with the top surface of a piston and is directed toward the vicinity of a spark plug. When the fuel injection mode is switched from the compression stroke injection to the intake stroke injection, the ignition timing is delayed during the execution of the intake stroke injection from when the fuel injection mode is switched until a predetermined period elapses compared with a case when the fuel injection mode is not switched.

摘要： A combustion control apparatus for an internal combustion engine that switches combustion modes at the proper timing. At the time of switching from a stratified-charge combustion mode to a homogeneous-charge combustion mode, the angle of an EGR valve is changed to the angle needed for the homogeneous-charge combustion mode first. When a predetermined delay time elapses after a request for switching the combustion mode has been made, substantial mode switching is carried out. The delay time is set based on engine speed and engine load.

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 switch valve is provided in a refrigerant circuit. The switch valve includes a first valve mechanism, a second valve mechanism, and a single valve housing incorporating the first and second valve mechanisms. The first valve mechanism is an electromagnetic valve. The first valve mechanism selectively connects and disconnects an outlet of a compressor with an inlet of a condenser in accordance with an electric current supply. The second valve mechanism is a differential pressure valve. The second valve mechanism selectively connects and disconnects the outlet of the compressor with an inlet of an evaporator in accordance with a difference between the pressure at the outlet of the compressor and the pressure at the inlet of the condenser. In this manner, the single switch valve, which includes the first and second valve mechanisms incorporated in the same valve housing, switches the refrigerant circuit between a path for a cooling operation and a path for a warming operation. This structure simplifies the configuration of the refrigerant circuit.

摘要： In a high-pressure pump for an internal combustion engine, a spill valve is inhibited from being stopped frequently. If the fuel injection amount becomes smaller than a predetermined amount, a method of determination is changed so that a feedforward term for duty control increases. This makes it unlikely that the duty ratio will become equal to zero. Operation resulting from a closing motion of the spill valve occurs substantially regularly. As a result, the circumstance where operation noise is generated irregularly is avoided, and a sense of incongruity given to the driver is reduced.
