  • Methods and systems for fuel canister purge flow estimation with an intake oxygen sensor
    Patent number: 9322367
    Abstract: Methods and systems are provided for estimating a fuel canister purge flow based on outputs of an intake manifold oxygen sensor. For example, during boosted engine operation when exhaust gas recirculation (EGR) is flowing below a threshold and purge is enabled, purge flow may be estimated based on changes in the sensor output while modulating a canister purge valve between an open and closed position. Then, during subsequent operation wherein EGR and purge flow are enabled, the output of the sensor may be adjusted based on the estimated purge flow.

    Abstract: Methods and systems are provided for varying a proportion of compressed air recirculated to a compressor inlet from a location downstream of the compressor and upstream of a charge air cooler and a location downstream of the charge air cooler. A temperature-controlled compressor recirculation flow is used to reduce condensation from EGR being ingested into the compressor. The temperature-controlled compressor recirculation flow is also used to address compressor surge.

  • Methods and systems for surge control
    Patent number: 9279374
    Abstract: Methods and systems are provided for recirculating compressed air across a compressor through a high flow and a low flow compressor recirculation path. Flow through the recirculation paths is controlled via respective valves and valve opening is adjusted based on a throttle mass flow so as to maintain a compressor flow rate at or above a surge constrained flow rate. By maintaining a sufficiently high compressor flow rate during steady state and transient conditions, the compressor state can be maintained outside a surge region.

  • Methods and systems for boost control
    Patent number: 9261051
    Abstract: Methods and systems are provided for managing a compressor temperature using EGR to address surge and condensation. A variable mixture of cooled compressor recirculation flow and hot EGR is provided to a compressor inlet. A composition of the mixture is adjusted to maintain a compressor inlet temperature sufficiently warm so as to reduce ingestion of condensation, and a compressor outlet temperature sufficiently cold to be within component temperature limits with flow above the surge limit.

  • Methods and systems for providing transient torque response
    Patent number: 9175629
    Abstract: A method and system for providing a suitable engine torque response during a transient condition is presented. In one example, when a desired inlet manifold pressure is greater than a throttle inlet pressure of a first throttle, a second throttle positioned upstream from the first throttle is opened to increase the throttle inlet pressure. The method may provide an appropriate torque response while minimizing impact on fuel economy.

  • Methods and systems for torque control
    Patent number: 9174637
    Abstract: Methods and systems are provided for improving surge control. When surge conditions are approached, a reference governor reduces engine airflow at a slower rate and to a higher level than the engine airflow required to meet the reduced torque demand. The excess torque resulting from the extra airflow is offset by applying a negative torque on the driveshaft via an electric machine coupled to the engine or via alternate engine actuator adjustments.

  • METHOD AND SYSTEM FOR CONTROL OF AN EGR VALVE DURING LEAN OPERATION IN A BOOSTED ENGINE SYSTEM
    Publication number: 20150292424
    Abstract: Methods and systems are provided for reducing EGR estimation errors during lean engine operating conditions. During lean engine operation, EGR is disabled if the estimated exhaust air-fuel ratio becomes leaner than a lean threshold. The lean threshold is adjusted based on an upper limit of EGR errors that may be tolerated by the engine at a given engine speed and load.
