The temperature elevation means 28 is composed such that a target temperature is determined based on the operation condition of an internal combustion engine 1 which is detected by the detecting means 33 and 36 to elevate the NOx catalyst temperature. Or alternatively, when the engine 1 is under a high load condition and its operation condition is not suitable for elevating the catalyst temperature, such an elevation is not carried out.

摘要： PROBLEM TO BE SOLVED: To hold a valve element to a desired opening and to increase the maximum flow passage area, while preventing soot and NOx from being emitted from an internal combustion engine by changing the flow passage area of recirculating exhaust gas by the rotation of the valve element and arranging the rotary shaft of the valve element perpendicularly to the flow direction of the recirculating exhaust gas. SOLUTION: An EGR control valve 31 is so formed that the rotary shaft 61 of a valve element 60 is arranged perpendicularly to the flowing direction of EGR gas and arranged in the center of the valve element 60. The flow passage area of the EGR gas is changed by rotating the valve element 60 about the rotary shaft 61. This constitution allows the EGR control valve 31 to hold a desired aperture without affected by the negative pressure even under the conditions that the negative pressure is generated in an air suction pipe just like a case of arranging a throttle valve. On the other hand, when the EGR passage width w1 is coincided with the maximum flow width W2 of the EGR gas, the maximum flow passage width W2 of the EGR gas can be set larger than the conventional one without enlarging the EGR passage width w1.

摘要： PROBLEM TO BE SOLVED: To match an injection rate with a target injection rate when an engine is operated for a long period by correcting a real fuel injection rate on the basis of an injection time memorized according to the operating condition of the engine, in a device wherein a rate of inert gas supplied to a combustion chamber is increased so as to suppress generation of soot. SOLUTION: In an internal combustion engine 1 wherein NOx absorbent 25 is arranged in an exhaust passage, a combustion mode is switched into first combustion wherein there is much rate of inert gas supplied into a combustion chamber more than an inert gas rate having a peaked soot generating rate and soot is hardly generated, and second combustion there is few rate of inert gas supplied into the combustion chamber more than the inert gas rate having the peaked soot generating rate. The rate of inert gas supplied into the combustion chamber more than the inert gas rate having the peaked soot generating rate is increased, and an injection time is memorized according to an operating condition of the engine. The injection time is corrected so as to set the fuel injection rate to a target injection rate according to the operating condition of the engine on the basis of the memorized injection time, thereby improves a control property.
