    • The rotational position detecting apparatus for an internal combustion engine includes a rotational angle sensor outputting a rotation angle signal indicative of a rotational angle of the internal combustion engine, an in-cylinder pressure sensor outputting an in-cylinder pressure signal indicative of an in-cylinder pressure of a cylinder of the internal combustion engine, and a reference rotational position detecting section which detects a specific rotational angle of the internal combustion engine at which the in-cylinder pressure becomes a predetermined reference pressure under a predetermined running condition of the internal combustion engine, and determines the detected specific rotational angle as a reference rotational position of the internal combustion engine. The reference rotational position detecting section detects the specific rotational angle at least a predetermined number of times, and determines an average value of the detected specific rotational angle as the reference rotational position.

    • 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.
    • 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。

    • A combustion control device is configured to control combustion in a combustion chamber of a compression ignition engine. An index detection unit is configured to detect multiple combustion state indices each indicating a combustion state in the combustion chamber. The multiple combustion state indices may include an ignition time point and an MFB50 time point, at which a combustion mass rate becomes 50% of total. A determination unit is configured to select a combustion state index from the multiple combustion state indices based on a determination condition such as an operation state of the engine. A control unit is configured to manipulate a parameter of the combustion state such as a fuel injection time point, at which a fuel injection valve injects fuel, so as to control the combustion state index at a target value.
