  • Method and system for catalyst feedback control
    Patent number: 10947910
    Abstract: Methods and systems are provided for catalyst control. In one example, a method may modulate a downstream catalyst by applying a square waveform to an outer feedback control loop. A fuel adjustment is performed in accordance with the square waveform to create an air-fuel ratio oscillation at an upstream catalyst brick and at a downstream catalyst brick.
    Type: Grant

  • Computer readable storage medium for use with engine having variable valve actuator during degradation
    Publication number: 20050103291
    Abstract: Piston to valve interference in an internal combustion engine is detected and alleviated by adjusting valve timing, valve lift, and/or compression ratio. Specifically, based on actuator motion, an actuator is selected to reduce potential interference. Further, potential sensor and hardware degradation are considered in controlling actuators to reduce potential interference.
