摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of S poisoning of an NOx occlusion reduction catalyst. SOLUTION: A catalyst converter 7 is situated in an exhaust passage 5 of an internal combustion engine. The catalyst converter 7 is formed that an SOx trap 73 to occlude SOx in an exhaust gas when an exhaust gas air-fuel ratio is lean and discharge occluded SOx when the exhaust gas air-fuel ratio is turned into a rich air-fuel ratio; a hydrogen producing catalyst 75 to produce hydrogen from HC, CO etc. in exhaust gas when the exhaust gas air-fuel ratio is turned into a rich air-fuel ratio; and an NOx occlusion reduction catalyst 77 to occlude NOx in exhaust gas when an exhaust gas air-fuel ratio is lean and effect occluding purification of the occluded NOx when an exhaust gas air-fuel ratio is turned into a rich air-fuel ratio are situated in the order named from the upper stream side. By situating a hydrogen producing catalyst between a SOx trap and NOx occluding reducing catalyst, SOx discharged from the SOx trap is prevented from occlusion into the NOx occlusion reduction catalyst, and desorption of SOx from the NOx occlusion reduction catalyst is promoted.

摘要： PROBLEM TO BE SOLVED: To prevent occurrence of engine output torque fluctuation caused by a secondary fuel injection in the expansion or exhaust stroke of an engine. SOLUTION: A cylinder fuel injection valve 111 ejecting fuel directly to the air cylinder of an internal combustion engine is arranged, and main fuel injection is performed toward a cavity 11a arranged on the top surface of a piston 11 in the latter half of air cylinder compression stroke and a secondary fuel injection making no contribution to combustion is performed thereto in the latter half of exhaust stroke. In the main fuel injection, ejected fuel is deflected by the cavity 11a and a combustible air-fuel mixture layer is laminated around an ignition plug 17. An exhaust valve 15a is opened at the time of the secondary fuel injection, therefore the whole amount of the deflected fuel is exhausted from an exhaust port 15 to the outside of the air cylinder. Therefore, fuel may not remain in the inside of the air cylinder by the secondary fuel injection, and output torque fluctuation may not be produced at the time of combustion in the next cycle.

摘要： PROBLEM TO BE SOLVED: To avoid NOx emission from NOx absorbent during stopping of an engine. SOLUTION: NOx absorbent 18 is arranged in an exhaust pipe 17 in an internal combustion engine 1, and a controlling circuit 30 which controls the amount of injected fuel in the engine 1 is provided. The control circuit 30 operates the engine 1 at lean air-fuel ratio, and estimates amount of NOx absorbed by the NOx absorbent 18, and when the amount of absorbed NOx reaches a specified value, operates the engine 1 at rich air-fuel ratio, emits NOx from the NOx absorbent, and reduces and purifies it. When an enginestop operation is done, the control circuit 30 does not stop the engine immediately after the stopping operation, and stops the engine after a specific period operation at rich airfuel ratio. Thus, NOx is emitted from the NOx absorbent and it is reduced and purified. Because NOx is not kept in the NOx absorbent during stopping of the engine, decrease of the NOx absorbent temperature after stopping of the engine is prevented from causing emission of non-purified NOx from the NOx absorbent.

摘要： PURPOSE: To control the discharge of NOx from the NOx absorbing agent based on the detected amount of the actual NOx in the NOx absorbing agent. CONSTITUTION: The NOx absorbing agent 18 is arranged in the engine emission passage. An O2 sensor 22 where the current proportional to the air fuel ratio is generated is arranged in the engine emission passage downstream of the NOx absorbing agent 18, and the amount of NOx which is actually absorbed in the NOx absorbing agent 18 when NOx is discharged is calculated based on the output signal of the O2 sensor 22. The estimated NOx is corrected based on the calculated NOx amount so as to express the actual amount of absorbed NOx , and the discharging effect of NOx from the NOx absorbing agent is made when the corrected value of the estimated NOx amount reaches the preset value.
