    摘要: A method for controlling air flow through a compressor recirculation passage, comprising: during a first condition: reducing air flow through the compressor recirculation passage based on a margin, the margin based on a rate of air flow at a compressor inlet, a rate of air flow through the compressor recirculation passage, and a rate of EGR flow. In this way, the CRV recirculation flow may be controlled to be less than the amount that could potentially backflow into an air filter disposed in the air intake passage, thus preventing EGR contained in the CRV recirculation flow from fouling the air filter with soot, oil and water.

    摘要: 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. The valve is fully opened to reduce hard surge, or fully closed to meet a transient increase in boost demand.
