摘要： A method for controlling EGR gas flow in an internal combustion engine during ongoing operation includes determining an engine operating point and a preferred EGR fraction for a cylinder charge based upon the engine operating point. A feed-forward command for controlling an external EGR gas flowrate to an engine intake manifold based upon the preferred EGR fraction for the cylinder charge is determined. An EGR ratio in the intake manifold is determined. And, the external EGR gas flowrate is controlled based upon the estimated EGR ratio in the intake manifold and the feed-forward command for controlling the external EGR gas flowrate.

摘要： A control system for an internal combustion engine having an exhaust gas recirculation device for recirculating a part of exhaust gases to an intake system of the engine is disclosed. An estimated exhaust gas recirculation amount is calculated using a neural network to which at least one engine operating parameter indicative of an operating condition of the engine is input. The neural network outputs an estimated value of an amount of exhaust gases recirculated by the exhaust gas recirculation device. At least one engine control parameter for controlling the engine is calculated based on the estimated exhaust gas recirculation amount.

摘要： An engine that re-circulates its exhaust gas suffers decreased accuracy in estimating an EGR rate real-time especially while the operating state of the engine is in a transitional state, which often results in torque fluctuations and deteriorated exhaust gas.A sensor for directly detecting an EGR flow rate is disposed in an EGR path. An EGR rate and in-cylinder oxygen concentration are calculated from the output value of that sensor. In addition, when this EGR rate calculation method is used, the calculation is properly switched between a steady operation state characterized by a low load and small rotational fluctuations and a transitional operating state including the acceleration and deceleration. This makes it possible to correctly estimate the EGR rate and the in-cylinder oxygen concentration under a wide range of engine operation conditions, and thereby to avoid the fluctuation of torque and the deterioration of exhaust gas.
摘要翻译：特别是在发动机的运转状态处于过渡状态时，再次循环排气的发动机在实际EGR估计中的精度降低，这通常导致扭矩波动和废气劣化。用于直接检测EGR流量的传感器设置在EGR通路中。从该传感器的输出值计算EGR率和缸内氧浓度。此外，当使用该EGR率计算方法时，可以在以低负载和小的旋转波动为特征的稳定运行状态和包括加速和减速的过渡运行状态之间适当地切换运算。这使得可以在较宽的发动机运转条件下正确地估计EGR率和缸内氧气浓度，从而避免扭矩的波动和废气的劣化。

摘要： An apparatus, system, and method are disclosed for determining the distribution of particulate matter on a particulate filter. The apparatus, in one embodiment, determines a first distribution of particulate matter by comparing the pressure change across the particulate filter with a change in engine operating conditions.

摘要： Various embodiments of an apparatus, system, and method are disclosed for managing regeneration event characteristics. For example, according to one embodiment, an apparatus for controlling the temperature of the output exhaust of an internal combustion engine for a regeneration event on a particulate matter filter includes a regeneration module, a turbocharger thermal management module, a fuel injection thermal management module, and an air intake thermal management module. The regeneration module determines a desired particulate matter filter inlet exhaust gas temperature for a regeneration event. The turbocharger thermal management module determines a variable geometry turbine (VGT) device position strategy. The fuel injection thermal management module determines a fuel injection strategy. The air intake thermal management module determines an intake throttle position strategy. The VGT device position strategy, the post-injection fuel injection strategy, and the intake throttle position strategy cooperatively achieve the desired particulate matter filter inlet exhaust gas temperature and maintain a fuel dilution level of the engine below a maximum fuel dilution level.
