    摘要: 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.

    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: The internal combustion engine control apparatus includes a calculation function of calculating an energy generation rate of an energy generated by combustion of fuel injected into a combustion chamber of a compression-ignition internal combustion engine, and an ignition detection function of detecting an ignition timing of the fuel in the combustion chamber on the basis of a timing at which the energy generation rate exceeds a first threshold value. When the energy generation rate due to a main injection, which is an object of ignition timing detection by the ignition detection function, exceeds the first threshold value at a plurality of timings, the ignition detection function determines an earliest one of the plurality of the timings as the ignition timing of the main injection.

    摘要: 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.

    摘要: A fuel injector performs a main injection and a pilot injection prior to the main injection. A fuel injection controller detects an ignition timing of a fuel injected at the main injection, detects a driving condition of the internal combustion engine, and varies a pilot injection quantity of the pilot injection when the driving condition is stable. Furthermore, the controller detects a variation in ignition timing due to a variation in the pilot injection quantity, and learns the pilot injection quantity based on the variation in ignition timing due to the variation in the pilot injection quantity.
