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.

摘要： An engine control apparatus which may be employed in automotive vehicles. The engine control apparatus is equipped with at least one of a combustion parameter or a controlled variable arithmetic expression. The combustion parameter arithmetic expression defines combustion conditions of the engine needed to achieve required values of engine output-related values such as exhaust emissions. The controlled variable arithmetic expression defines how to operate actuators for an operation of the engine to meet desired combustion conditions of the engine. The use of the combustion parameter or controlled variable arithmetic expression achieves simultaneous agreement of the engine output-related values with required values without mutual interference between combustion parameters associated with the combustion conditions.

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。

摘要： There is disclosed a fuel property detector for detecting a property of fuel injected by a fuel injector into a cylinder of an internal combustion engine. The fuel property detector includes an injection commander, a change detector, and a fuel property determiner. The injection commander commands the fuel injector to perform a fuel injection for fuel property detection into the cylinder of the engine. The change detector detects a change in the rotational speed of the engine which is caused by the fuel injection for fuel property detection. The fuel property determiner determines the property of the fuel based on the change in the rotational speed of the engine detected by the change detector.
