摘要: Methods and systems are provided for managing a compressor temperature using EGR to address surge and condensation. A variable mixture of cooled compressor recirculation flow and hot EGR is provided to a compressor inlet. A composition of the mixture is adjusted to maintain a compressor inlet temperature sufficiently warm so as to reduce ingestion of condensation, and a compressor outlet temperature sufficiently cold to be within component temperature limits with flow above the surge limit.

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 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. The temperature-controlled compressor recirculation flow is also used to address compressor surge.

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.

摘要: 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. Concurrent adjustments to a wastegate may be used to provide boost pressure control.

摘要: A method and system for providing a suitable engine torque response during a transient condition is presented. In one example, when a desired inlet manifold pressure is greater than a throttle inlet pressure of a first throttle, a second throttle positioned upstream from the first throttle is opened to increase the throttle inlet pressure. The method may provide an appropriate torque response while minimizing impact on fuel economy.
