Abstract
A turbocharged engine air system is disclosed. The engine air system includes at least two devices requiring vacuum, a turbocharger having a compressor fluidly connected to an intake manifold of an engine, a first evacuator and a second evacuator. The first evacuator defines a first motive section, a first discharge section, and at least two first suction ports. The first motive section of the first evacuator is fluidly connected to the compressor, and each of the at least two first suction ports are fluidly connected to one of the at least two devices requiring vacuum. The second evacuator defines a second motive section, a second discharge section, and at least two second suction ports. The second motive section of the second evacuator is fluidly connected to at least one of the at least two devices requiring vacuum.
