Abstract
Systems and methods are provided for engine systems including a vacuum-powered multiple tap aspirator coupled between atmospheric, an engine crankcase, or another source and a vacuum source such as a compressor inlet or engine intake manifold. The multiple tap aspirator includes a suction tap arranged in a throat of the aspirator, a suction tap arranged in a diverging cone of the aspirator, and a suction tap arranged in a straight exit tube downstream of the diverging cone of the aspirator. The aspirator provides vacuum generation and suction flow over a range of vacuum levels at the suction taps, and suction flow only passes through a single check valve before entering the aspirator.
