  • 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.
    Type: Grant

  • TURBOCHARGER CONTROL
    Publication number: 20110314807
    Abstract: Various systems and methods for controlling a turbocharger of an engine via a wastegate are described. In one example, actuation of the wastegate is limited when outside a range, the limits of the range varying with boost pressure, turbine inlet pressure, turbine outlet pressure, and atmospheric pressure. In this manner, a tracking error may be reduced when controlling the boost pressure and using the boost pressure to actuate the wastegate in a boost-based wastegate configuration.
