  • Patent number: 11313287
    Abstract: Methods and systems for unsticking a stuck gaspath actuator are disclosed. In one embodiment, an engine operating method includes adjusting exhaust valve timing of one or more cylinders of an engine in response to an indication that a gaspath actuator is stuck in position. In this way, pressure waves in an exhaust manifold and/or an intake manifold may be generated, which may act to unstick the gaspath actuator.

  • Patent number: 11220970
    Abstract: Methods and systems for an engine controller are described. In one example, the engine controller includes a reference control system and a disturbance rejection control system. The engine controller avoids use of integral feedback in the reference control system, while permitting integral feedback in the disturbance rejection control system, to improve controller response without unduly increasing engine pumping work.

  • Patent number: 11220962
    Abstract: Methods and systems are provided for improving turbocharger response in a boosted engine. In one example, a current turbocharger performance may be monitored, if meeting and operating in an optimum region for efficiency (e.g., on compressor and/or turbine maps), engine may be operated with a steady state exhaust valve opening (EVO) timing in an optimum position based on engine mapping (e.g., engine pumping work). Otherwise, the EVO timing may be advanced (opening earlier) to release more energy into the exhaust or retarded to release less, to move turbocharger to desired performance. By adjusting EVO timing to achieve desired turbocharger response and performance, faster response is achieved.

  • Patent number: 11187178
    Abstract: Methods and systems for operating an engine that includes an after treatment system are described. In one example, traffic data and navigation system data are a basis for deciding whether or not to increase heat output of an engine to ensure operation of the after treatment system. In particular, one or more actuators may be adjusted to minimize fuel consumption and/or reduce feedgas emissions while generating sufficient heat to maintain after treatment system operation.

  • Patent number: 11181057
    Abstract: Methods and systems for operating an engine with a pump that is driven via the engine are described. In one example, start of opening of an injector that supplies a fluid to an engine exhaust system is timed based on a period of the pump so that the output of the fluid injector may be repeatable in the presence of fluid pressure oscillations that are periodic with pump rotation.

  • Patent number: 11107307
    Abstract: Methods and systems are provided for probabilistic on-board diagnostics. In one example, a method may include calculating a probabilistic metric for a sample of a measured operating condition of a vehicle system component, averaging a plurality of probabilistic metrics including the probabilistic metric for a plurality of samples including the sample, and determining whether the vehicle system component is degraded based on the averaged plurality of probabilistic metrics. In this way, the functionality of a vehicle system component may be continuously monitored without regard for specific diagnostic entry conditions.

  • Patent number: 11073063
    Abstract: Methods and systems are provided for diagnostics of a gasoline particulate filter in an exhaust system after confirming that specific conditions are met including that an exhaust tuning valve is not degraded. In one example, a method may include indicating degradation of a hose coupled across a particulate filter responsive to a difference between a first differential pressure and a second differential pressure being greater than a threshold, the first differential pressure measured by a differential pressure sensor positioned in the hose responsive to a downstream exhaust tuning valve being fully open, the second differential pressure measured by the differential pressure sensor responsive to the exhaust tuning valve being fully closed.

  • Patent number: 11041423
    Abstract: Methods and systems are provided for diagnosing a gasoline particulate filter in an engine exhaust passage. A pressure-flow relationship of the filter is learned in a low engine speed and high engine speed range. Degradation of the filter is identified based on a substantial separation between the curve fits at the high and low speed range.

  • Patent number: 10883410
    Abstract: Methods and systems are provided for detecting NOx sensor degradation based on results from a NOx sensor self-diagnostic (SD) test performed after a key-off event. In one example, a method may comprise waiting a duration to perform a SD test of a NOx sensor after a key-off event until engine operating conditions stabilize and reach a set of qualifying conditions. One or more SD tests may be performed after waiting the duration, but outputs generated under conditions where one or more of a temperature at the sensor is greater than a threshold, and an oxygen concentration is outside a threshold range, may be excluded when determining whether or not the NOx sensor is degraded.
