  • Publication number: 20190264625
    Abstract: Methods and systems are provided for exhaust heat recovery and EGR cooling via a single heat exchanger. In one example, a method may include selecting a specific mode of operation of an engine exhaust system with the heat exchanger based on engine operating conditions and an estimated fuel efficacy factor. The fuel efficiency factor may take into account fuel efficacy benefits from EGR and exhaust heat recovery.

  • Patent number: 10378400
    Abstract: Methods and systems are provided for adjusting engine compression ratio (CR) and spark timing to attain particulate filter (PF) regeneration temperature. In one example, a method may include, in response to PF load reaching a threshold and PF temperature being lower than the PF regeneration temperature, lowering the CR and then selectively adjusting spark timing based on an estimated residual gas fraction (RGF) at the lower CR.

  • Patent number: 10221792
    Abstract: A system and method are described for reducing NOx emissions following deceleration fuel shut off (DFSO). The method comprises: cutting off fuel to the engine during a deceleration event; open loop operating the engine air/fuel ratio rich of stoichiometry for a predetermined time after the deceleration event; feedback controlling the air/fuel ratio on average near a value rich of stoichiometry for a preselected time after said predetermined time; and feedback controlling the air/fuel ratio returning to stoichiometry after the preselected time.

  • Publication number: 20190063284
    Abstract: Methods and systems are provided for differentiating an exhaust air leak from a catalyst monitor sensor degraded with a slow-response. In one example, a pressure proximate an exhaust system particulate filter less than a threshold pressure may indicate an exhaust air leak and responsive to the indication of the exhaust air leak, the thresholds for monitoring the catalyst monitor sensor response may be adjusted. In this way, the impact of an exhaust air leak on catalyst monitor output may be accounted for so that subsequent monitoring for threshold catalyst may continue to be performed accurately in the presence of an exhaust air leak.

  • Publication number: 20180355809
    Abstract: Methods and systems are provided for a single heat exchanger coupled to a main exhaust passage upstream of one or more exhaust catalysts or in between two exhaust catalysts for exhaust heat recovery and exhaust gas recirculation (EGR) cooling. In one example, in the pre-catalyst configuration of the heat exchanger, during exhaust heat recovery, a portion of exhaust may be routed via the heat exchanger while the remaining portion of exhaust may be routed directly to the exhaust catalysts, and fueling may be adjusted on a per-cylinder basis to maintain a target exhaust air-fuel-ratio at the exhaust catalysts.

  • Patent number: 10087803
    Abstract: Methods and systems are provided for operating an engine exhaust aftertreatment system to increase the efficiency of an exhaust underbody catalyst and reduce engine emissions. In one example, a bypass passage may be coupled to a main exhaust passage and during conditions which may adversely affect functionality of the underbody catalyst, exhaust may be opportunistically routed via the bypass passage avoiding the underbody catalyst. Exhaust heat may be recovered via a heat exchanger coupled to the bypass passage, and the heat may be used for engine heating, and passenger cabin heating.
