摘要： To provide a control apparatus for an internal combustion engine which can effectively utilize a scavenging effect while suppressing a torque difference in the internal combustion engine provided with a variable valve mechanism which makes a valve overlap period variable.When a scavenging effect utilization condition that the scavenging effect using exhaust pressure pulsation can be effectively utilized is established, a valve overlap period is set so as to overlap with a timing at which a trough of the exhaust pressure pulsation comes. In this occasion, a set value of the valve overlap period is limited such that an increase amount of a torque index value associated with the setting of valve overlap period does not exceed a predetermined permissible value.

摘要： An internal combustion engine control apparatus that prevents an abrupt change in the air amount at the time of supercharger switching. The control apparatus enters a small turbo operating state in which a small turbocharger is mainly operative, during relatively low-rotation-speed and low-load side, and enters a large turbo operating state in which a large turbocharger is mainly operative, in a relatively high-rotation-speed and high-load. In the small turbo operating state, the control apparatus can exercise charging efficiency enhancement control by using a scavenging effect. Before switching from the small turbo operating state to the large turbo operating state, the control apparatus predicts whether the large turbocharger will build up its boost pressure quickly or slowly. When slow boost pressure is predicted, the control apparatus exercises charging efficiency enhancement control to provide a low degree of charging efficiency enhancement.

摘要： The present invention has for its problem to be solved to provide a technique in which in an exhaust gas purification system for an internal combustion engine with a filter being arranged on an exhaust passage for trapping PM in an exhaust gas, it is possible to suppress an excessive rise in temperature of the filter during execution of filter regeneration control more preferably. In the present invention, when the amount of intake air in the internal combustion engine decreases up to an amount at which an excessive rise in temperature of the filter might be induced during the execution of filter regeneration control, the oxygen concentration of an ambient atmosphere around the filter is decreased up to a target oxygen concentration. At this time, when the amount of intake air being decreased is more than a certain amount, the oxygen concentration of the ambient atmosphere around the filter is lowered mainly by supplying a reducing agent to a catalyst that is arranged at a location upstream of the filter or supported on the filter (S106). On the other hand, when the amount of intake air being decreased is equal to or less than the certain amount, the oxygen concentration of the ambient atmosphere around the filter is lowered mainly by performing exhaust gas throttling by means of an exhaust gas throttle valve (S104).
