  • Methods and system for improving transient torque response
    Patent number: 10920689
    Abstract: Methods and systems are provided for improving engine torque response during transient condition. In one example, a method may include adjusting intake throttle and exhaust waste-gate valve based on the operator torque demand and concurrently, scheduling exhaust gas recirculation (EGR) and variable cam timing (VCT) based on a predicted torque shortfall ratio. The scheduling of EGR and VCT is independent of the actual position of intake throttle and exhaust waste-gate valve.
    Type: Grant

  • Method and system for variable cam timing device
    Patent number: 10465568
    Abstract: Methods and systems are described for an engine with a cam torque actuated variable cam timing phaser. Phaser positioning control is improved by reducing inaccuracies resulting from inadvertent spool valve and/or phaser movement when the spool valve is commanded between regions. In addition, improved spool valve mapping is used to render phaser commands more consistent and robust.

  • Method and system for pre-ignition control
    Patent number: 9695755
    Abstract: Methods and systems are provided for addressing pre-ignition occurring while operating with blow-though air delivery. A variable cam timing device used to provide positive intake to exhaust valve overlap is adjusted in response to an indication of pre-ignition to transiently reduce valve overlap. Pre-ignition mitigating load limiting and enrichment applied during a blow-through mode is adjusted differently from those applied when blow-through air is not being delivered.
