摘要：
An air induction system consisting of a cylindrical main flow tube, a helical vane disposed within the main flow tube, and, preferably, a noise absorbing perforated tube disposed within the main flow tube in concentric relation to the helical vane. The twist direction of the helical vane provides air flow rotation in the same direction of rotation as the turbine wheel. The helical vane causes noise reflection and enhancement of noise attenuation by the perorated tube and its adjoining one or more acoustic cavities.
