  • METHOD FOR PRE-IGNITION CONTROL
    Publication number: 20170082081
    Abstract: Various systems and methods are described for controlling pre-ignition in a boosted engine in a newly manufactured vehicle. One method comprises, during a pre-delivery phase of the vehicle, operating the boosted engine in a pre-delivery calibration with a first, higher enrichment, in response to a pre-ignition event. The pre-delivery calibration is deactivated during a post-delivery phase and the boosted engine is operated with a second, lower enrichment in response to a pre-ignition event.

  • Method and system for pre-ignition control
    Patent number: 9551288
    Abstract: Methods and systems are provided for reducing late burn induced cylinder pre-ignition events. Forced entry of residuals from a late burning cylinder into a neighboring cylinder may be detected based on engine block vibrations sensed in a window during an open exhaust valve of the late burning cylinder. In response to the entry of residuals, a pre-ignition mitigating action, such as fuel enrichment or deactivation, is performed in the neighboring cylinder.

  • METHOD AND SYSTEM FOR DETECTION OF HOT SPARK PLUG FOULING
    Publication number: 20170002786
    Abstract: Methods and systems are provided for inferring spark plug fouling due to accumulation of fuel additives thereon. In one example, an engine controller may infer spark plug hot fouling based on higher than expected exhaust temperatures by correlating the elevated exhaust temperature with late combustion phasing due to additive accumulation. A confidence factor of the spark plug hot fouling detection may be enhanced based on data regarding concurrent misfire and/or pre-ignition events.

  • Dedicated-EGR cylinder with variable charge motion
    Patent number: 9534530
    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.

  • Spark plug fouling detection for ignition system
    Patent number: 9534984
    Abstract: Methods and systems are provided for inferring spark plug fouling due to accumulation of fuel additives thereon. In one example, an engine controller may infer spark plug fouling due to accumulation of fuel additive based on a combination of engine operating parameters correlated with spark plug health. For example, the engine operating parameters may include a change in an adaptive knock term, an engine pre-ignition rate, and engine exhaust oxygen sensor switching frequency over a vehicle drive cycle, and an engine misfire rate.
