摘要： Methods and systems are provided for diagnosing compressor bypass valve degradation. In one example, a method may include indicating degradation of a compressor bypass valve coupled in a compressor bypass based on intake aircharge temperature measured upstream of a compressor inlet via an air charge temperature sensor.

摘要： Methods and systems are provided for adapting a compressor surge line in real-time. In one example, a method may include retarding a surge line in response to a number of surge events greater than a threshold number of surge events, and advancing the surge line in response to a number of aggressive tip-out events, that do not result in surge, greater than a threshold number of tip-out events.

摘要： Methods and systems are provided for calibrating a compressor surge line. In one example, a method may include adjusting the compressor surge line based on a vehicle speed in addition to a compressor pressure ratio. For example, at higher vehicle speeds, above a threshold vehicle speed, a less aggressive surge line calibration may be utilized in order to improve drivability while at lower vehicle speeds, below the threshold vehicle speed, a more aggressive surge line calibration may be utilized for NVH mitigation.

摘要： Systems and methods for operating a compressor and a compressor recirculation valve of a turbocharged engine to avoid the possibility of compressor surge are presented. The systems and methods position the compressor recirculation valve responsive to a compressor surge line that is based on two other compressor surge lines that may be a function of compressor pressure ratio and compressor flow.

摘要： Systems and methods for improving compressor recirculation valve operation of an engine that includes a compressor are presented. The systems and methods adjust a position of a waste gate while the compressor recirculation valve is operated in a closed loop mode to maintain engine intake manifold throttle inlet pressure during a diagnostic mode to adapt operation of the compressor recirculation valve.
