  • SYSTEMS AND METHODS FOR CONTROL OF TURBINE-GENERATOR VIA EXHAUST VALVE TIMING AND DURATION MODULATION IN A SPLIT EXHAUST ENGINE SYSTEM
    Publication number: 20160131054
    Abstract: Methods and systems are provided for reducing exhaust energy delivered to a turbine of a turbine-generator coupled to a split exhaust engine system in order to reduce turbine over-speed conditions and/or to reduce a generator output. In one example, a method may include retarding a first timing of a first exhaust valve utilized to deliver a blowdown portion of exhaust energy to the turbine, and/or advancing a second timing of a second exhaust valve utilized to deliver a scavenging portion of exhaust energy to an exhaust catalyst in response to a turbine speed greater than a threshold speed.

  • Methods and systems for an oxygen sensor
    Patent number: 9328679
    Abstract: Methods and systems are provided for accurately learning the zero point of an intake gas oxygen sensor during selected engine no-fueling conditions. The learned zero point is used to infer EGR flow and accordingly adjust EGR valve control. In addition, EGR valve leakage is diagnosed based on the zero point learned during a DFSO adaptation relative to a zero point learned during an idle adaptation.

  • Systems and methods for exhaust catalyst temperature control
    Patent number: 9297320
    Abstract: Methods and systems are provided for exhaust catalyst temperature control by metering exhaust bypass flow from a dedicated EGR cylinder. A continuously variable bypass valve may be adjusted to vary an amount of exhaust directed to an exhaust catalyst from a dedicated EGR cylinder via a bypass passage relative to exhaust recirculated to the engine intake via an EGR passage. At lower catalyst temperatures, more exhaust is metered via the bypass passage to enable catalyst temperature to be maintained above an activation level.

  • Systems and methods for stopping and starting an engine with dedicated EGR
    Patent number: 9284920
    Abstract: Methods and systems are provided for operating an engine including a DEGR system during start-stop and DFSO conditions. In one example, the DEGR cylinder may be deactivated prior to deactivating the non-DEGR cylinder group and stopping the engine, to purge EGR from the intake system.

  • Devices and methods for exhaust gas recirculation operation of an engine
    Patent number: 9279393
    Abstract: An engine is provided that includes an exhaust gas recirculation (EGR) conduit in fluidic communication with a first exhaust valve in a cylinder and an intake system, an exhaust conduit in fluidic communication with a second exhaust valve in the cylinder and an emission control device. During operation with the first valve active and the second valve deactivated, a fixed EGR level can be provided. However, during operation with the first valve deactivated and the second valve active, increased engine output can be achieved with reduced EGR without requiring additional exhaust throttling or switching valves.

  • SYSTEMS AND METHODS FOR A MODIFIED CYLINDER FIRING INTERVAL IN A DEDICATED EGR ENGINE
    Publication number: 20160047341
    Abstract: Methods and systems are provided for operating exhaust valves of an engine to create more even exhaust pulses to a turbine. More specifically, the engine may include one or more dedicated exhaust gas recirculation (EGR) cylinders routing exhaust to an engine intake and one or more non-dedicated EGR cylinder routing exhaust to the turbine. In one example, a method may include operating a first set of exhaust valves of a group of non-dedicated EGR cylinders to have no exhaust valve opening overlap and operating an exhaust valve of a dedicated EGR cylinder so that opening of the second exhaust valve overlaps with opening of exhaust valves of two cylinders of the group of non-dedicated EGR cylinders.

  • SYSTEMS AND METHODS FOR EGR CONTROL
    Publication number: 20160040607
    Abstract: Methods and systems are provided for varying a location and rate of EGR delivered to an engine from a dedicated EGR cylinder. The dedicated EGR cylinder is configured with a plurality of exhaust valves controlled via a cam profile switching mechanism that allows the time and duration of opening of each exhaust valve to be varied. By selectively opening one exhaust valve at a time, exhaust from the dedicated EGR cylinder can be delivered to a pre-compressor location, a post-compressor location, or to the exhaust manifold, while bypassing all engine cylinders.

    Abstract: Methods and systems are provided for adjusting charge motion control devices coupled to a series of cylinders organized into cylinder groups, one of the cylinder groups including a dedicated EGR cylinder group wherein the cylinders are the only engine cylinder routing exhaust to an engine intake. In one example, a first cylinder group may be a dedicated cylinder group recirculating exhaust to the intake manifold while a second cylinder group may be a non-dedicated cylinder group routing exhaust to a turbine. A method may include adjusting a first charge motion control device coupled to the first cylinder group and a second charge motion control device coupled to the second cylinder group to vary a charge motion level between the first and second cylinder groups.
