METHOD AND APPARATUS FOR CONTROLLING TURBINE EFFICIENCY

摘要

The present invention relates to a method of controlling turbine efficiency in a turbo unit provided on an internal combustion engine, comprising the steps of : providing a flow of gas in an area upstream a turbine at a direction different to the flow of exhaust gases in the same area, regulating said flow by a valve, controlling said valve from a control unit having at least boost pressure and/or EGR flow as input parameters.
