摘要： An engine torque control apparatus is applied to an engine control system comprising an engine for rotating an output shaft by using torque generated through combustion in cylinders. In the apparatus, exhaust gas passing through an exhaust passage of the engine is partially recirculated into an intake passage of the engine. Also, variable control is conducted in the apparatus, when an air-fuel ratio indicating a proportion between air and fuel supplied into the cylinders of the engine is changed to a leaner air-fuel ratio, so that torque parameters for increasing/decreasing output torque of the engine can be variably controlled. As a result, torque fluctuation associated with a temporarily changing recirculated uncombusted fuel quantity can be cancelled in a manner suitable for the temporarily changing recirculated uncombusted fuel quantity, at least during a predetermined period immediately after timing for changing the air-fuel ratio.

摘要： In an engine, when it is determined that catalyst, which is held on a filter substrate of a particulate filter, is not in an active state, an ECU executes a fuel injection for mainly obtaining an engine power near a top dead center of a crank. Then, the ECU executes a subsequent fuel injection after lapse of a sufficient injection interval, which does not cause misfiring, to increase the temperature of exhaust gas outputted from the engine. In this way, the temperature of the filter is rapidly increased.

摘要： An ECU controls an opening degree of an EGR gas switch valve based on a temperature of intake air and a load state of an engine in such a manner that a temperature of exhaust gas becomes a suitable temperature, which is suitable for regeneration of a particulate filter arranged in an exhaust gas passage. In this way, cooled EGR gas, which passes a main passage, and hot EGR gas, which passes a bypass passage, are appropriately mixed. In a case, where reliability of an EGR valve cannot be maintained, EGR cut is performed.

摘要： An electronic control unit of an internal combustion engine calculates a basic post-injection quantity of temperature increasing means if a deposition quantity of particulate matters deposited on a diesel particulate filter (DPF) exceeds a predetermined value. Then, a final post-injection quantity is calculated by correcting the basic post-injection quantity based on a temperature correction value, which is calculated by multiplying a deviation between DPF upstream exhaust gas temperature and target temperature and past temperature correction values by feedback gains. The feedback gains are switched in accordance with a delay in an exhaust gas temperature change in a present operating state, based on an intake air quantity sensed by an air flow meter. Thus, response can be improved, while maintaining stability.

摘要： A fuel injection controller of an internal combustion engine decreases a target intake quantity stepwise and increases an opening degree command value of an EGR valve stepwise when the controller switches control to rich combustion control. Accordingly, an intake quantity gradually decreases and an EGR quantity gradually increases, so an oxygen quantity flowing into a combustion chamber (cylinder inflow oxygen quantity) gradually decreases. The injection quantity is gradually increased in accordance with the gradual decrease of the oxygen quantity. Thus, the fuel injection controller can perform processing for making an air fuel ratio rich in order to discharge nitrogen oxides from an occlusion agent while appropriately inhibiting torque fluctuation.
摘要翻译：内燃机的燃料喷射控制器逐步降低目标进气量，并且当控制器将控制器切换到浓燃烧控制时逐步增加EGR阀的开度指令值。因此，进气量逐渐降低，EGR量逐渐增加，因此流入燃烧室的氧气量（气缸流入氧气量）逐渐降低。根据氧气量的逐渐减少，喷射量逐渐增加。因此，燃料喷射控制器可以进行空气燃料比浓缩的处理，以便在适当地抑制转矩波动的同时从阻塞剂中排出氮氧化物。
