  • METHODS AND SYSTEMS FOR PROVIDING TRANSIENT TORQUE RESPONSE
    Publication number: 20140352669
    Abstract: A method and system for providing a suitable engine torque response during a transient condition is presented.

  • PRESERVING COMBUSTION STABILITY DURING COMPRESSOR-SURGE CONDITIONS
    Publication number: 20140316675
    Abstract: A method to avoid over-dilution of an intake-air charge of an engine includes, during a first condition, applying at least some feedback control to the opening and closure of a valve that adjustably admits exhaust to the intake-air charge. During a second condition predictive of compressor surge, no feedback control is applied to the opening or the closure of the valve. Rather, feedforward control is applied to the closure of the valve so that stability in the engine is maintained even during surge conditions.

  • METHODS AND SYSTEMS FOR BOOST CONTROL
    Publication number: 20140260241
    Abstract: Methods and systems are provided for improving boost response. A continuously variable compressor recirculation valve and a wastegate are adjusted in complementary frequency bands to move compressor operation away from a surge limit and reduce boost delivery errors. An intake throttle is also concurrently adjusted to offset manifold air-flow rate errors resulting from the wastegate or recirculation valve adjustments.

  • TWIN TURBOCHARGER WASTEGATE CONTROL
    Publication number: 20140174074
    Abstract: An engine system comprises a first turbocharger including a first wastegate, first wastegate actuator, and first turbocharger sensor, a second turbocharger including a second wastegate, second wastegate actuator, and second turbocharger sensor, and a controller configured to adjust the first wastegate actuator so that a parameter of the first turbocharger matches a parameter of the second turbocharger, based on output from the first and second turbocharger sensors. In this way, turbocharger output between the two turbochargers may be balanced.

  • STORED COMPRESSED AIR MANAGEMENT FOR IMPROVED ENGINE PERFORMANCE
    Publication number: 20130305718
    Abstract: Methods and systems are provided for raising an exhaust temperature to spin a turbocharger turbine and reduce turbo-lag. Pressurized air is discharged from a boost reservoir into an intake manifold while spark retard is increased to expedite exhaust heating while also increasing a net combustion torque. By expediting turbine spin-up in response to a tip-in, turbo-lag is reduced and engine performance is improved.

  • Turbocharger control
    Patent number: 8572961
    Abstract: Various systems and methods for controlling a turbocharger of an engine via a wastegate are described. In one example, actuation of the wastegate is limited when outside a range, the limits of the range varying with boost pressure, turbine inlet pressure, turbine outlet pressure, and atmospheric pressure. In this manner, a tracking error may be reduced when controlling the boost pressure and using the boost pressure to actuate the wastegate in a boost-based wastegate configuration.
