  • SYSTEMS AND METHODS FOR EGR CONTROL
    Publication number: 20150354477
    Abstract: Methods and systems are provided for reducing torque transients experienced when a dedicated EGR cylinder is deactivated to reduce EGR. Before deactivating the dedicated cylinder, an intake throttle position and spark timing of remaining engine cylinders is adjusted to build-up torque reserve in anticipation of a negative torque transient at deactivation. Then, the throttle position or spark timing is adjusted to reduce torque when a positive torque transient is expected.

  • SYSTEMS AND METHODS FOR PURGE AND PCV CONTROL
    Publication number: 20150337696
    Abstract: Methods and systems are provided for improving purge air-fuel ratio control. Fuel vapors from a canister and the crankcase are selectively purged to a group of cylinders and not to remaining engine cylinders. Exhaust is recirculated from the selected group of cylinders to the engine intake wherefrom the EGR is ingested in the remaining engine cylinders and the selected group of cylinders.

  • Method and system for exhaust gas recirculation control
    Patent number: 9181904
    Abstract: Methods and systems are provided for adjusting an EGR valve and one or more intake throttles responsive to the output of an intake oxygen sensor to provide a desired amount of EGR flow while maintaining engine torque. The adjustments are coordinated to improve distributed control of the EGR valves and intake throttles, and enable EGR flow even when one actuator is limited.

  • 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.

    Publication number: 20150267604
    Abstract: Methods and systems are provided for estimating water storage in a charge air cooler (CAC). In one example, an amount of water accumulating in the CAC may be based on an output of an oxygen sensor positioned downstream of the CAC and ambient humidity. Further, engine actuators may be adjusted to purge condensate from the CAC and/or reduce condensate formation based on the amount of water inside the CAC.

  • BRANCH COMMUNICATION VALVE FOR A TWIN SCROLL TURBOCHARGER
    Publication number: 20150260085
    Abstract: Methods and systems are provided for a branch communication valve in a twin turbocharger system. A branch communication valve may be positioned adjacent to a dividing wall separating a first scroll and a second scroll of the twin turbocharger. In an open position, the branch communication valve increases fluid communication between the first scroll and the second scroll and in a closed position, the branch communication valve decreases fluid communication between the first scroll and the second scroll.

  • Methods and systems for boost control
    Patent number: 9091202
    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.

  • METHOD AND SYSTEM FOR IMPROVED DILUTION PURGING
    Publication number: 20150136074
    Abstract: Methods and systems are provided for expediting EGR purging in a hybrid vehicle during transient operations, such as tip-out to lower load conditions. In response to decreasing engine torque demand, engine fueling is disabled and a motor is used to spin the engine unfueled until a desired LP-EGR rate is achieved. Alternatively, engine operation is maintained with EGR disabled until the desired LP-EGR rate is achieved, and the excess engine torque generated is stored in a system battery.

  • DETERMINING EXHAUST GAS RECIRCULATION COOLER FOULING USING DPOV SENSOR
    Publication number: 20150128916
    Abstract: Methods and systems are provided for determining degradation of an EGR cooler based on differential pressure across the EGR cooler during EGR flow. In one example, the differential pressure across the EGR cooler may be based on differential pressure across an EGR valve and a pressure downstream from the EGR valve with and without EGR flow. The pressure downstream from the EGR valve may be a compressor inlet pressure or an intake manifold pressure in a low pressure EGR system or high pressure EGR system, respectively.

  • METHOD AND SYSTEM FOR IMPROVED DILUTION TOLERANCE
    Publication number: 20150128917
    Abstract: Methods and systems are provided for expediting purging of LP-EGR from an air intake system during conditions of decreasing engine load. During a tip-out, an EGR valve is closed while the engine is shifted to a VDE mode of operation to improve engine tolerance to EGR at lower engine loads and until the EGR is sufficiently purged. A non-VDE mode is resumed if higher engine loads are restored, else, a deceleration fuel shut-off mode is selected if the tip-out continues to zero load.

  • Exhaust-gas regeneration under rich conditions to improve fuel economy
    Patent number: 9014947
    Abstract: A method for operating a boosted gasoline engine. The method includes diluting an intake air charge of the engine to a first level of dilution when operating at a stoichiometric air-to-fuel ratio. The method also includes, in response to a condition of excessive exhaust temperature downstream of the engine, diluting the intake air charge of the engine to a second, greater level of dilution while operating at an enriched air-to-fuel ratio.
