摘要： An engine control apparatus which may be employed in automotive vehicles. The engine control apparatus is equipped with a controlled variable arithmetic expression which defines correlations between combustion parameters associated with combustion conditions of an engine and controlled variables actuators for an operation of the engine. This eliminates the need for finding relations of optimum values of the controlled variables to the combustion parameters through adaptability tests, which results in a decrease in burden of an adaptability test work and a map-making work on manufacturers. The engine control apparatus also works to learn or optimize the controlled variable arithmetic expression based on actual values of the combustion parameters, thereby avoiding undesirable changes in correlations, as defined by the controlled variable arithmetic expression, due to a change in environmental condition.

摘要： An engine torque control apparatus is applied to an engine control system comprising an engine for rotating an output shaft by using torque generated through combustion in cylinders. In the apparatus, exhaust gas passing through an exhaust passage of the engine is partially recirculated into an intake passage of the engine. Also, variable control is conducted in the apparatus, when an air-fuel ratio indicating a proportion between air and fuel supplied into the cylinders of the engine is changed to a leaner air-fuel ratio, so that torque parameters for increasing/decreasing output torque of the engine can be variably controlled. As a result, torque fluctuation associated with a temporarily changing recirculated uncombusted fuel quantity can be cancelled in a manner suitable for the temporarily changing recirculated uncombusted fuel quantity, at least during a predetermined period immediately after timing for changing the air-fuel ratio.

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.

摘要： An abnormality determination device of a cylinder pressure sensor calculates a gain (sensing sensitivity coefficient) and an offset (bias) indicating an output characteristic of the cylinder pressure sensor. The device determines existence or nonexistence of an abnormality in the gain and the offset respectively. When the device determines that the abnormality exists, the device performs failsafe processing set in modes different from each other between the case of the abnormality in the gain and the case of the abnormality in the offset. As the failsafe processing in the case of the abnormality in the gain, the device performs processing for substantially prohibiting usage of a sensor value of the cylinder pressure sensor in control (fuel injection timing control) by using an alternative value (specified value) instead of the sensor value of the cylinder pressure sensor.
