摘要： A method for restricting an excessive temperature rise in an internal combustion engine according to the present invention can provide a technology that enable to restrict an excessive temperature rise of a filter more reliably in an internal combustion engine having the filter provided in the exhaust passage for collecting particulate matter in the exhaust gas. In that method, when the running state of the internal combustion engine becomes idle running during the filter regeneration process, the oxygen concentration in the exhaust gas flowing into the filter is reduced. After that, when the running state of the internal combustion engine shifts from the idle running to a running state with an engine load higher than in the idle running, the oxygen concentration in the exhaust gas flowing into the filter is gradually increased.

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： 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).
