Abstract

Systems and method are provided for an internal combustion engine with boosted operation. In an example, this includes operating the engine with boosted intake pressure via a supercharger and with supercharger flow regulated by a vacuum actuated bypass valve, and in response to a supercharger outlet temperature greater than a first threshold, increasing a blow through air passing from the engine intake to engine exhaust without combustion in a cylinder of the engine due to engine intake and exhaust valves having positive valve overlap; and then in response to the supercharger outlet temperature greater than a second, higher, threshold, limiting engine airflow.
