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, a fuel feed unit supplies a fuel uniformly into a burner so as to prevent incomplete combustion in the burner. When a vaporization member is provided in the burner, the fuel feed unit supplies the fuel uniformly all over the surface of the vaporization member so that the incomplete combustion in the burner is also prevented. In addition or alternatively, the fuel feed unit includes a fuel feed pipe and a valve unit which is provided at a tip portion of the fuel feed pipe, so as to prevent emissions of an unburned fuel. In addition or alternatively, a temperature of the fuel supplied to the burner is monitored, and an operation of the fuel feed unit or an air feed unit for supplying combustion air to the burner is controlled based on the monitored fuel temperature so as to provide a desirable air-fuel mixture for preventing incomplete combustion in the burner. An amount of the fuel supplied to the burner or an oxygen concentration in an exhaust gas after combustion in the burner may be monitored instead of the fuel temperature.

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： 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.
