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： A compression ignition internal combustion engine includes injectors, each of which injects fuel into a corresponding cylinder. An ECU determines target ignition timing based on engine operational information and adjusts fuel injection start timing and a fuel injection quantity of each injector based on the target ignition timing. The engine further includes an air/fuel ratio sensor, which senses an oxygen concentration of exhaust gas. The ECU corrects the target ignition timing based on the oxygen concentration, which is sensed with the air/fuel ratio sensor, with reference to a predefined relationship between the oxygen concentration and ignition timing for achieving a generally equal constant torque of the engine.

摘要： In a combustion heater, at the time of ignition, a fuel supply amount is increased in a stepwise fashion. On the other hand, at the time of extinction, the fuel supply amount is decreased in a stepwise fashion. The fuel supply amount is increased stepwise using different fuel increasing amounts or different fuel increasing periods, both depending on heat quantities generated by a burner at respective fuel increasing time points. At the time of extinction, the fuel supply amount and an air supply amount are both reduced to given values, respectively, and held at the given values for a given time period. After lapse of the given time period, the fuel supply amount is reduced to zero, while the air supply amount is held at the given value for a further given time period. The air supply amount is changed with a given time delay relative to a change of the fuel supply amount. The time delay may be adjusted depending on a temperature in the burner.
摘要翻译：在燃烧加热器中，在点火时，以逐步的方式增加燃料供给量。另一方面，在灭火时，燃料供给量以逐步的方式减少。使用不同的燃料增加量或不同的燃料增加周期，燃料供给量逐步增加，这两者都取决于在各燃料增加时间点由燃烧器产生的热量。在灭火时，燃料供给量和空气供给量都分别减小到给定值，并且在给定时间段内保持在给定值。在经过给定时间段之后，燃料供给量减少到零，同时空气供给量在给定时间段内保持在给定值。空气供给量相对于燃料供给量的变化以给定的时间延迟而变化。可以根据燃烧器中的温度来调整时间延迟。

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。
