摘要： Systems and methods for controlling automotive powertrains using a distributed control architecture are disclosed. A distributed control system may include a supervisory control unit for controlling one or more powertrain subsystems, and one or more subsystem control units in communication with the supervisory control unit. The supervisory control unit can be configured to execute a central optimization algorithm that computes variables from across multiple powertrain subsystems, and then outputs a number of globally approximated command values to each associated subsystem control unit. In some embodiments, the central optimization algorithm can be configured to solve a global cost function or optimization routine. One or more of the subsystem control units can be configured to execute a lower-level algorithm or routine, which can comprise a higher-fidelity model than that used by the central optimization algorithm.

摘要： A catalyst system that may regenerate while removing pollutants from an exhaust gas of an engine. The system may have a converter with multiple segments of chambers. At least one of the chambers may be regenerated while the remaining chambers are removing pollutants from the exhaust. The chambers may be rotated in turn for one-at-a-time regeneration. More than one chamber may be regenerated at a time to remove collected pollutants. The system may have plumbing and valves, and possibly mechanical movement of the chambers, within the system to effect the changing of a chamber for regeneration. The chambers connected to the exhaust may be in series or parallel. A particulate matter filter may be connected to the system, and it also may be regenerated to remove collected matter.

摘要： A system for automatic multivariable calibration of an engine controller. The system may take inputs which include actuator setpoints, sensor measurements, performance requirements, and so forth. There may be an algorithm to compute engine calibration parameters for the controller. Each of the actuators may be separately stepped through to experimentally obtain actuator input and sensor output data. Algorithmic processing of the experimentally obtained data may be performed to calculate parameters of a model of an engine. A model based control design algorithm may then be invoked to obtain the calibration parameters for a controller. The calibrated controller may be tested with real or simulated engine conditions. The performance related to the parameters may be analyzed and determination of the acceptability of the data be made. If not acceptable, the parameters may be reprocessed. If acceptable, the calibration parameters may be downloaded to the engine controller for application and use.

摘要： A fluid flow control system for controlling flow of a primary fluid to a downstream flow-inducing device includes a moving fluid expander with variable expansion ratio and variable speed arranged to receive the flow of the primary fluid and to expand the primary fluid, resulting in a reduction in temperature of the primary fluid. The system further includes an optional heat exchanger arranged to receive the reduced-temperature primary fluid as well as a higher-temperature secondary fluid and to cause varying degrees of heat exchange between the primary and secondary fluids such that the secondary fluid is cooled by the primary fluid. The primary fluid is discharged from the heat exchanger and is supplied to the flow-inducing device.

摘要： A sensor system for detecting the presence of at least one specific component in a fluid medium such as an exhaust gas. A sensor is mounted in a sensor body for detecting the presence of at least one specific component and providing a representative signal that is transmitted to a remote receiver for processing. A power source such as a thermopile provides power for the sensor and the transmitter. Preferred are sensors that detect a plurality of different components in the gas and provide a distinct signal for each component. A preferred transmitter is designed to transmit at a low duty cycle so as to conserve power. A preferred sensor is electronic, has the capability for self-diagnostics and self-calibration, and causes a change in current when exposed to the component, such as a functionalized field effect transistor.

摘要： A turbocharger system for an air-throttled engine includes a variable flow expander (VFE) in the intake air conduit system that supplies intake air to the engine. At part-load operation, the VFE expands the air by an amount that is controllable, and thus regulates the air flow as needed by the engine. The power extracted by the VFE from the intake air flow is fed to the turbocharger, which helps to achieve quicker turbocharger response and improve scavenging of exhaust gases from the engine. The VFE can be a variable expansion ratio turbine.

Also, an exhaust system with regeneration may include temperature, pressure, NOx and differential pressure sensors. A processor may be connected to the sensors. There may be emission sampling lines connected to different parts of the system and to a collector to take, store, detect and analyze samples. A processor may be connected to the collector.
