  • Patent number: 10590836
    Abstract: Methods and systems are provided for improving surge control in a boosted engine system configured with an electric motor to provide electrical boost assistance. Tip-in and tip-out surge are addressed by increasing the opening of a compressor recirculation valve and coordinating the recirculation valve opening with adjustments to an exhaust waste-gate position and a power output by the electric motor. The adjustments enable an intake airflow to be provided that operates the compressor outside a surge region while providing a target boost pressure as operator torque demand increases or decreases.

  • Patent number: 10550773
    Abstract: Methods and systems are provided for operating a split exhaust engine system that provides blowthrough air and exhaust gas recirculation to an intake passage via a first exhaust manifold and exhaust gas to an exhaust passage via a second exhaust manifold. In one example, one or more valves of a set of first exhaust valves coupled to the second exhaust manifold may be deactivated in response to select engine operating conditions, while maintaining active all valves of a set of second exhaust valves coupled to the first exhaust manifold. The select engine operating conditions may include one or more of a deceleration fuel shut-off condition, a part throttle condition, and a cold start condition.

  • Patent number: 10465575
    Abstract: Methods and systems are provided for warming an engine and/or engine fluids. In one example, a method may comprise powering on an electric motor of an intake boost device to generate heat, circulating coolant and/or engine oil through the boost device to absorb the heat produced by the boost device, and then flowing the coolant and/or engine oil to the engine to transfer the heat absorbed from the boost device to the engine. In this way, an engine may be warmed without running the engine rich by using the heat generated by the electric motor of the boost device to warm the engine.

  • Patent number: 10232841
    Abstract: Systems and methods for operating a driveline of a hybrid vehicle are disclosed. In one example, an engine may enter or stay in one of two cylinder modes in response to a request to a negative torque capacity of an electric machine being insufficient to provide a desired driveline braking torque. One cylinder mode operates cylinders with cylinder valves held closed and without fuel being injected to the cylinders while the other cylinder mode operates cylinders with valves that open and close without fuel being injected to the cylinders.

  • Patent number: 10151223
    Abstract: Systems and methods for operating an engine with deactivating valves are presented. In one example, a groove in a camshaft controls oil flow to a valve operator that selectively activates and deactivates a poppet valve of a cylinder. The groove moves with the camshaft so that oil delivery to the valve operator is timed properly to deactivate and reactivate the cylinder.

  • Patent number: 10138803
    Abstract: Methods and systems are provided for a wastegate of a turbocharger including a valve plate, valve actuation mechanism, and a bifurcated wastegate passage. In one example design, the wastegate may include a valve plate having an interior with a multiplane curved surface and a first mating feature centered along the curved surface, the curved surface forming a raised edge and a side opening on opposite sides of the valve plate; and a passage bifurcated by a central wall, an end of the central wall including a second mating feature adapted to have face-sharing contact with the first mating feature. The first mating feature may be either a rib or recessed slot formed on the valve plate, and the second mating feature may be one end of the central wall.

  • Patent number: 10018097
    Abstract: Methods and systems are provided for exhaust flow in an engine system including a split-exhaust manifold for expediting exhaust catalyst light-off and engine warm-up while reducing condensation in the engine system. In one example, a method may include, before exhaust catalyst light-off, flowing all or more exhaust gases, via a first exhaust valve and a first exhaust manifold, to an exhaust catalyst by passing a heat exchanger. Further, after light-off but before engine coolant warms up to a threshold temperature, all or more exhaust may be delivered to the heat exchanger, via a second exhaust valve and a second different manifold, prior to flowing to the exhaust catalyst; and exhaust gas recirculation may not be provided until the coolant reaches the threshold temperature to reduce condensation.

  • Patent number: 9976500
    Abstract: Methods and systems are provided for adjusting a cylinder deactivation pattern to improve camshaft phasing. In response to a request for actuating a camshaft phaser of a variable cam timing device, a cylinder deactivation pattern is adjusted by reactivating cylinders that were deactivated while deactivating other cylinders that were active, while maintaining a total number of deactivated/active cylinders. Cylinders are selected for reactivation or deactivation based on their individual camshaft torsion signatures so that sufficient cam torque is generated to actuate the phaser and provide the requested phasing.
