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： Based on results of a knock control for adjusting ignition timing in accordance with the occurrence of knocking, an electronic control unit computes deposit required ignition timing akgrg, which is ignition timing determined by taking adhesion of deposits in an internal combustion engine into consideration. Based on the deposit required ignition timing akgrg, the electronic control unit reduces a vvt allowable variable range of a target VVT advancement amount, which is a control target value of a variable valve timing mechanism. The electronic control unit corrects a required ignition timing based on the actual VVT advancement amount vt, which is chanted according to the reduction of the allowable variable range of the target VVT advancement amount. As a result, problems resulting from the adhesion of deposits are effectively avoided.

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 direct-fuel-injection-type internal combustion engine is equipped with an injector for injecting fuel directly into a combustion chamber of a cylinder. A controller controls the degree of opening of a throttle valve for adjusting the amount of air drawn into the combustion chamber and sets the throttle valve to a closed valve state by setting the degree of opening of the throttle valve to a degree of opening that is on the closed valve side of a post-engine start target degree of opening, when the engine is to be started. After it is determined that a start of the engine has been accomplished, the controller opens the throttle valve by gradually increasing the degree of opening of the throttle valve from the degree of opening of the closed valve state to the post-engine start target degree of opening.

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： 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.

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.
