摘要： A system includes a filter, a sensor, a processor, and a memory. The filter can be coupled to an engine exhaust and can operate in an accumulating mode during which particulate matter (PM) from the engine is trapped and also operate in a regenerating mode during which PM in the filter is emitted. The sensor is coupled to a discharge port of the filter and has an output to provide a sensor signal based on a concentration of PM in the filtered exhaust. The processor is coupled to receive the sensor signal and operable to determine at least one of a base level for the sensor signal during the accumulating mode and a regenerate level for the sensor signal during the regenerating mode, and operable to determine a calibration value for the sensor using at least one of the base level and the regenerate level. The memory stores the calibration value.

摘要： A flow control mechanism connected to the intake and exhaust systems of an engine. The mechanism may achieve recirculation of exhaust gases despite varying differential pressures or delta pressures between the systems, particularly since intake pressures may often exceed exhaust pressures. Pressure sensors may be situated proximate to the input and output of the flow control mechanism. There may a flow sensor proximate to the flow control mechanism. Cylinder pressure or pulse sensors may be situated in or about the engine. A processor may be connected to various sensors and provide prompt active control of a valve or like device in the flow control mechanism. Such valve may operate sufficiently quickly so as to prevent backflow from the intake system into the exhaust system upon sudden pressure changes in the systems. The quickness of the active valve control may also permit recirculating stipulated amounts of exhaust gas to each cylinder.

摘要： A multivariable controller that models the interaction between groups of sensors and groups of actuators during the operation of an engine. By accounting for the interactive effects that a group of actuators has on a sensor or group of sensors, improved system performance may be achieved. When emission sensors are used, such as NOX and/or PM sensors, the multivariable controller may help control the various engine actuators to reduce emissions of the engine.

摘要： Systems and methods for controlling an engine using feedback from one or more sensors are disclosed. An illustrative control system for controlling a diesel engine may include one or more post-combustion sensors adapted to directly sense at least one constituent of exhaust gasses emitted from the exhaust manifold of the engine, and a state observer for estimating the internal state of the diesel engine based on feedback signals received from the post-combustion sensors and from subsequent use of the estimated state in a controller that sends the actuator setpoints. The post-combustion sensors can be configured to directly measure emissions such as oxides of nitrogen (NOx) and/or particulate matter (PM) within the exhaust stream, and provide such information to a state observer that, in turn, updates an internal dynamical state based on these measurements. In some cases, other sensors such as a torque load sensor, an in-cylinder pressure sensor, and/or a fuel composition sensor can be further used to update the internal state of the state space model, as needed. Using an estimated state from the state observer, a state feedback controller can compute and adjust various actuator setpoints from values that more accurately represent the true state of the system.
