摘要： A fuel injection control apparatus for an internal combustion engine is provided. A controller directs a fuel injector to spray a learning injection quantity of fuel and determines a resulting increase in speed of the engine. The controller determines the quantity of the fuel actually sprayed from the fuel injector based on the increase in speed of the engine and calculates a correction factor which compensates for a difference between the learning injection quantity and the actual injection quantity. The controller also determines a variation in load acting on a driving member of a torque transmission mechanism. When such a variation is great undesirably, the controller stops spraying the learning injection quantity. The controller may determine the increase in speed of the engine based on the degree of the variation in load. This ensures the accuracy in calculating the correction factor regardless of the variation in load.

摘要： When a combustion mode of an engine is a diffuse combustion mode in which an initial rising inclination of a heat-release-rate is steep, an electronic control unit (ECU) calculates an ignition timing in which the heat-release-rate exceeds an ignition determining value. Thus, even if a cylinder pressure sensor has a gain deviation or an offset deviation, the ignition timing is accurately detected to control the injection start timing. When the combustion mode is a premix combustion mode in which the initial rising inclination of the heat-release-rate is moderate, a peak arising timing of the heat-release-rate is calculated. Thus, the peak arising timing is accurately detected to control the injection start timing.

摘要： A valve control device corrects a change rate of an opening degree of a valve in accordance with engine rotation speed when deposit elimination operation is performed. The valve control device corrects an inclination between a positive maximum opening degree and a negative maximum opening degree of the valve in accordance with the engine rotation speed when the deposit elimination operation is performed. Thus, when the engine rotation speed is low and a noise accompanying the deposit elimination operation becomes more audible, the change rate of the opening degree of the valve is reduced. As a result, the noise accompanying the deposit elimination operation is reduced and annoyance for vehicle occupants is reduced.

摘要： An injection quantity control apparatus for accurately performing an injection quantity learning process in a diesel engine creates an environment for obtaining a characteristic value in a one-to-one relationship with an actual injection quantity. A controller performs a one-shot injection operation for a cylinder of an engine while the environment is established. An injection command quantity is corrected based on an engine speed variation caused by the one-shot injection. After establishment of the condition and before the injection, the opening of a valve is controlled to be smaller than a reference and an opening of each of a diesel throttle and variable turbocharger is controlled to be larger than a reference. A composition of an air flowing into a combustion chamber is stabilized to ensure that the characteristic value detected after the one-shot injection is in a one-to-one relationship with the actual injection quantity.

摘要： An electronic control unit (ECU) of a fuel injection control system of an internal combustion engine feedback-controls injection timing so that a cylinder pressure maximum value coincides with a target pressure value in an operation range, in which the cylinder pressure maximum value increases as ignition timing advances and torque increases as the ignition timing advances. The ECU feedback-controls the injection timing so that the ignition timing coincides with target timing in another operation range, in which the cylinder pressure maximum value increases as the ignition timing advances but the torque decreases as the ignition timing advances. Thus, the torque can be outputted efficiently by selecting the appropriate feedback control in accordance with the operation range.

摘要： An electronic control unit (ECU) of an injection control system of an internal combustion engine determines that a load of a fuel pump is stabilized when a pressure-feeding operation delay elapses since a command pressure-feeding quantity outputted to the fuel pump reaches a certain pressure-feeding quantity necessary to maintain a target injection pressure. The ECU permits a single injection when a waiting period necessary to measure rotation speeds once for each cylinder before the single injection is performed elapses since the load of the fuel pump is stabilized. Thus, the single injection timing is determined based on the time point when the command pressure-feeding quantity is stabilized, the pressure-feeding operation delay, and the waiting period. Therefore, an injection quantity learning operation can be performed highly accurately in a short period.
摘要翻译：内燃机的喷射控制系统的电子控制单元（ECU），由于输出到燃料泵的指令压力供给量达到一定程度，因此当经过供压运转延迟时，燃料泵的负荷稳定保持目标注射压力所需的加压量。当燃料泵的负载稳定时，在执行单次喷射之前，在经过了每个气缸一次测量转速所需的等待时间之后，ECU允许单次喷射。因此，基于指令加压量稳定的时间点，加压运转延迟和等待期间来确定单次喷射正时。因此，可以在短时间内高精度地执行喷射量学习操作。

摘要： A low pressure EGR system includes a low pressure EGR passage connecting a downstream portion of an exhaust gas cleaner disposed in an exhaust passage to an upstream portion of a supercharger compressor disposed in an intake passage. A device for trapping foreign particles contained in EGR gas to be recirculated is disposed in the low pressure EGR passage. The trapping device may be positioned lower than the passage connected thereto so that foreign particles drop into the device by their own weight. A cross-sectional area of the trapping device may be made larger than that of the passage so that the flow speed of the EGR gas is reduced in the trapping device and the foreign particles are easily trapped. A valve for closing the low pressure EGR passage may be disposed therein to stop EGR when malfunctions are detected in the exhaust gas cleaner or the supercharger.

摘要： A fuel injection controller calculates a difference between a rotation speed fluctuation amount of an engine in the case where an injection for learning is performed and the rotation speed fluctuation amount in the case where the injection for the learning is not performed as a rotation speed increase amount. The controller calculates an actual injection amount actually injected from an injector based on a rotation state of the engine. The controller calculates a difference between the actual injection amount and a command injection amount outputted to the injector as a characteristic deviation and corrects the command injection amount to reduce the characteristic deviation. The controller prohibits the correction of the command injection amount when a variation in the rotation speed increase amount is equal to or greater than a specified value.
