Abstract:
1. An angular velocity changing device arranged in an air intake line of an internal combustion engine comprising: a) one or more curved fins; b) each of the one or more curved fins being generally similar in shape and comprising a first edge and a second edge, the first edge aligned generally perpendicular to a direction of airflow and comprising a length that is greater than a length of the second edge; c) each of the one or more curved fins having a connecting edge, the fins being attached to each other at a central location along the connecting edge, each of the one or more curved fins being offset from the next fin at a first angle so as to evenly divide a space inside the air intake line; d) each of the one or more curved fins being curved from the first edge to the second edge at a second angle; e) at least two fins having a contact edge distal to the connecting edge configured to contact the air intake line and hold the device in a stationary position; and f) each of the one or more curved fins being configured to change the angular velocity of air traveling in the air intake line.
