ABSTRACT:
A method, device, and system for controlling a flow of a fluid moving through a pipe are presented. The device includes a truncated cone having a first diameter at an inlet and a second diameter at an outlet and a bracket attached to the truncated cone. The first diameter of the truncated cone is larger than the second diameter. The bracket is a curved sheet positioned around at least a part of the truncated cone and having an adjustable bracket diameter. The bracket diameter is measured from a center axis extending through a center of the truncated cone. Attaching the device to a fluid flow pipe reduces turbulence in the flow through the pipe, allowing a more streamlined fluid exit from the pipe. When used with an air intake pipe for an internal combustion engine, the device allows more horsepower and mileage to be extracted from the engine.
