ABSTRACT:
Systems and methods for an engine are described. In one example, a system may include a variable venturi coupled in an intake of the engine; an exhaust gas recirculation system having an exhaust gas recirculation flow path, the exhaust gas recirculation flow path coupled to the variable venturi; and a vacuum-utilizing device or system coupled to the variable venturi. In another example, a method may include coordinating adjustment of an exhaust gas recirculation valve coupled to the exhaust gas recirculation system, a fuel vapor purging valve coupled to the fuel vapor purging system, and the variable venturi in response to operating conditions.
