Abstract:
PROBLEM TO BE SOLVED: To minimize an H 2 S discharge even though an engine is started when a catalyst temperature is high. SOLUTION: This device is provided with an NO x occluding catalyst 34 for purifying exhaust gas in an internal combustion engine, and a water temperature sensor 42 for detecting the temperature of the NO x occluding catalyst 34. When in starting an engine, if the temperature of the NO x occluding catalyst 34 is above a predetermined value (T), a high temperature restarting determination flag is started, so that an exhaust gas air-fuel ratio is controlled to be set to a leaner side than usual. Thereby, an H 2 S amount discharged in high temperature restarting can be reduced. COPYRIGHT: (C)2004,JPO

PROBLEM TO BE SOLVED: To improve the catalyst temperature control precision of a system to control a NOx catalyst temperature by controlling an exhaust gas temperature flowing into an NOx catalyst by an exhaust gas temperature regulating device. SOLUTION: An estimated catalyst temperature value TMPSM is determined based on an engine driving state, and an estimated exhaust gas temperature value at the position of an exhaust gas temperature sensor 28 (estimated sensor position temperature value) TMPOSM is determined based on the estimated catalyst temperature value TMPSM. An estimated correction quantity value DLTMP is determined based on deviation between the estimated sensor position temperature value TMPOSM and exhaust gas temperature TMPSENS detected by the exhaust gas temperature sensor 28, and the estimated catalyst temperature value TMPSM is corrected using the estimated correction quantity value DLTMP, so that the estimated catalyst temperature value TMPSM is determined with favorable precision. The exhaust gas temperature regulating device 25 is thus controlled in accordance with the estimated catalyst temperature value TMPSM thus determined, thereby the temperature of the NOx catalyst 26 can be controlled with favorable precision within a high NOx purification ratio temperature range.

PROBLEM TO BE SOLVED: To provide a torque control device of an internal combustion engine having high torque controllability by correcting torque after torque variation due to variation in combustion is suppressed. SOLUTION: When a surge level is higher than a predetermined value A, a drive force control is prohibited (step 110). The variation in combustion of the internal combustion engine is suppressed by correcting the opening timing of an intake valve by a VVT mechanism (step 112). When the surge level is equal to or lower than the predetermined value A, the execution of the drive force control is permitted (step 118). COPYRIGHT: (C)2007,JPO&INPIT
