摘要： An exhaust recirculation apparatus is provided to an engine. A high-pressure EGR passage branches from upstream of a turbine of a turbocharger in an exhaust system for recirculating exhaust gas to downstream of a compressor of the turbocharger in an intake system. A high-pressure EGR regulating unit controls exhaust gas through the high-pressure EGR passage. A low-pressure EGR passage branches from downstream of the turbine in the exhaust system for recirculating exhaust gas to upstream of the compressor in the intake system. A low-pressure EGR regulating unit controls exhaust gas through the low-pressure EGR passage. A control unit feedback-controls the high-pressure EGR regulating unit, and open-controls the low-pressure EGR regulating unit when exhaust gas is recirculated through the high-pressure EGR passage and the low-pressure EGR passage. The control unit feedback-controls the low-pressure EGR regulating unit when exhaust gas is recirculated through only the low-pressure EGR passage.

摘要： A single fuel injection is performed in either one of cylinders during fuel cut control of a diesel engine to sense torque generated with the single fuel injection based upon an increase amount of rotation speed of a crankshaft at the time. Presence/absence of abnormality in an injection start timing of an injector is determined based on a difference in torque caused when the single fuel injection is performed at multiple command injection start timings. Thus, the presence/absence of the abnormality in the injection start timing can be sensed without using a nozzle lift sensor, whereby inhibiting an increase in the number of components.

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： An oxidation catalyst is disposed upstream of a diesel particulate filter (DPF) in an exhaust passage of a diesel engine. An electronic control unit (ECU) operates temperature increasing circuit to combust and eliminate particulate matters deposited on the DPF. The ECU determines execution and stoppage of regeneration of the DPF based on a quantity of the particulate matters deposited on the DPF. The ECU increases an exhaust gas recirculation quantity (EGR quantity) during the regeneration to reduce an intake air quantity from the intake air quantity in a non-regeneration period and to achieve a flow rate of the exhaust gas passing through the DPF suitable for the temperature increase. The ECU corrects a valve opening degree of an EGR control valve based on the sensed intake air quantity to reduce a variation in the exhaust gas flow rate.

摘要： An ECU controls an opening degree of an EGR gas switch valve based on a temperature of intake air and a load state of an engine in such a manner that a temperature of exhaust gas becomes a suitable temperature, which is suitable for regeneration of a particulate filter arranged in an exhaust gas passage. In this way, cooled EGR gas, which passes a main passage, and hot EGR gas, which passes a bypass passage, are appropriately mixed. In a case, where reliability of an EGR valve cannot be maintained, EGR cut is performed.

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： An electronic control unit (ECU) of an engine calculates a first modification value for decreasing a correction value of an injection period when a state variation of the engine caused by a single injection is greater than a target value. The ECU calculates a second modification value for increasing the correction value when the state variation is less than the target value. The second modification value is greater than the first modification value. Thus, a period necessary to converge the correction value can be shortened when the correction value is increased. The first modification value is increased if a difference between the state variation and the target value exceeds a permissible value when the correction value is decreased. Thus, the injection quantity is decreased quickly to prevent excessive fuel injection.
摘要翻译：当发动机由单次喷射引起的状态变化大于目标值时，发动机的电子控制单元（ECU）计算用于减小喷射周期的校正值的第一修改值。当状态变化小于目标值时，ECU计算用于增加校正值的第二修改值。第二修改值大于第一修改值。因此，当校正值增加时，可以缩短收敛校正值所需的时间。如果当校正值减小时，如果状态变化和目标值之间的差超过允许值，则第一修改值增加。因此，喷射量迅速降低以防止燃料喷射过多。
