Methods and systems for boost control


Methods and systems are provided for varying a proportion of compressed air recirculated to a compressor inlet from a location downstream of the compressor and upstream of a charge air cooler and a location downstream of the charge air cooler. A temperature-controlled compressor recirculation flow is used to reduce condensation from egr being ingested into the compressor.

Method and system of cleaning a control valve


A method and system of cleaning a turbocharger bypass control valve, the control valve being operable to vary the position of a bypass valve and thereby vary the amount of flow bypass across a turbine and/or compressor of a turbocharger for an engine. The method comprises: determining whether the control valve may require cleaning; adjusting the duty cycle of the shuttle so as to increase a flow of fluid through the control valve and clean the control valve; and adjusting a throttle position of the engine and thus the engine torque output to compensate for the adjustment in the amount of boost provided by the turbocharger..

Methods and systems for surge control


Methods and systems are provided for improving a margin to surge. A compressor recirculation valve is held at a semi-open position during steady-state boosted engine operation and operation in a soft surge region.

Methods and systems for boost control


Methods and systems are provided for coordinating adjustments to a compressor recirculation valve with adjustments to a binary flow turbine scroll valve to reduce surge. The scroll valve is closed to increase turbine energy while the compressor recirculation valve is opened to increase compressor flow.

Methods and systems for condensation control


Methods and systems are provided for reducing condensate accumulation at a charge air cooler (cac) during cold ambient conditions. A wastegate may be held closed while a compressor recirculation valve is held open during an engine cold start so as to use compressor heating and increased compressor recirculation to expedite cac heating.

Methods and systems for egr control


Methods and systems are provided for using compressor recirculation flow via a venturi to enhance low pressure egr flow. The opening of a compressor recirculation valve can be adjusted based on egr flow demand to recirculate cooled compressed air through a venturi while generating vacuum for drawing egr.
