  • Publication number: 20170051659
    Abstract: Methods and systems for operating an engine that includes a compressor and charge air cooler are disclosed. In one example, air flow through the charge air cooler is increased in response to condensation accumulating in the charge air cooler without increasing engine torque. Air flow through the charge air cooler is increased to gradually reduce condensation within the charge air cooler.

  • Patent number: 9551276
    Abstract: Systems and methods are provided for reducing surge in a boosted engine system. One method comprises adjusting an opening of a compressor recirculation valve to allow a compressor recirculation flow based on a combination of a nominal compressor recirculation flow and a filtered nominal compressor recirculation flow. The nominal compressor recirculation flow may be calculated as a difference between a desired compressor flow rate based on a surge limit of compressor and an estimated throttle mass flow rate.

  • Patent number: 9528430
    Abstract: Systems and methods for compensating for deposits that may accumulate within a compressor recirculation valve positioned in parallel with a turbocharger compressor are presented. The systems and methods adjust actuators to maintain engine operation such that it may be more difficult for a driver to become aware that a compressor recirculation valve diagnostic is being executed.

  • Publication number: 20160369716
    Abstract: Methods are provided for improving boost pressure control in a boosted engine system. In one example, during a tip-in, an air bypass coupled across an intake compressor of the engine system may be kept open for a predetermined time. Keeping the air bypass open during tip-in enables the compressor to spin faster, and this faster speeds may translate into reaching a desired higher boost when the air bypass is subsequently closed in less time than heretofore possible.

  • Patent number: 9506474
    Abstract: 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.

  • Publication number: 20160339920
    Abstract: Systems and methods for improving shifting of a manual transmission coupled to an engine are presented. In one example, a load provided to the engine is increased in response to a transmission gear upshift so that engine speed may be quickly decreased to synchronize with transmission input speed, thereby allowing quicker manual transmission gear shifts.

  • Publication number: 20160201584
    Abstract: 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.

    Abstract: 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.

  • Publication number: 20160160806
    Abstract: Methods and systems are provided for improving boost pressure control by adjusting a variable compressor recirculation valve. In one example, a method may include adjusting a position of a continuously variable compressor recirculation valve based on amount of sludge accumulation on the valve. The amount of sludge accumulation may be estimated based on a difference between total intake flow downstream of a compressor recirculation passage outlet but upstream of the passage, and total engine flow entering engine cylinders.
