Abstract
A mass air flow sensor housing for reducing backflow includes a U-shaped air flow path having an elliptical inlet and an outlet. A mass air flow sensor is positioned in the U-shaped air flow path. A converging ellipse inlet to the U-shaped air flow path reduces turbulent air flow. A deflecting wedge positioned upstream of the outlet creates a low pressure area adjacent the outlet for promoting air flow through the U-shaped bypass.
