Abstract
An airflow converger belonging to the field of auto parts, that was developed to improve air supply conditions and performance of internal combustion engines includes: a tubular body equipped at an upper end with an air inlet, having parallel fins that direct airflow lines in parallel; internally, the body has an inner surface that acts on the airflow; and an opposite end of the body has an outlet positioned horizontally and connected to an air receiving medium like a carburetor or throttle body of a vehicle's engine system, the airflow lines flowing in parallel as they move through the body from the inlet to the outlet.
Claims5
An airflow converger comprising:
- a tubular body equipped, at an upper end, with an air inlet in a vertical plane open to the environment or connected to the outlet of an air filter and provided with spaced, parallel, vertically oriented, nonintersecting fins that direct airflow lines in parallel;
- internally, said body has an inner surface for changing turbulent airflow with high recirculation rate to laminar airflow with minimized or annulled recirculation rate and turbulence intensity upon exit from the body;
- and an opposite end of said body has an outlet positioned horizontally and connected to an air receiving medium like a carburetor or throttle body of a vehicle's engine system;
- said airflow lines flowing in parallel as they move through said body from said inlet to said outlet;
- wherein the tubular body is defined by a broadened upper section, prismatic, with convex walls, and with said inlet;
- said body is also internally obstruction-free and defined by a lower section in a substantially cone frustum format, funneled from a base of the upper section and ending in a cylindrical section having said outlet.

An airflow converger comprising:
- a tubular body equipped, at an upper end, with an air inlet in a vertical plane open to the environment or connected to the outlet of an air filter and provided with spaced, parallel, vertically oriented, nonintersecting fins having flat, parallel sides that direct airflow lines in parallel;
- internally, said body has an inner surface for changing turbulent airflow with high recirculation rate to laminar airflow with minimized or annulled recirculation rate and turbulence intensity upon exit from the body;
- and an opposite end of said body has an outlet positioned horizontally and connected to an air receiving medium like a carburetor or throttle body of a vehicle's engine system;
- said airflow lines flowing in parallel as they move through said body from said inlet to said outlet;
- said tubular body being internally obstruction-free and defined by a broadened upper section, prismatic, with convex walls, and with said inlet;
- said body also being defined by a lower section in a substantially cone frustum format, funneled from a base of the upper section and ending in a cylindrical section having said outlet;
- the inner surface being defined by an upper region in an essentially semi-parabolic format, with an axis of revolution substantially coinciding with a vertical medial axis of the inlet, by an intermediary region essentially in a cone frustum format, that extends and is funneled from a base of the upper region, and by a cylindrical lower region extending from the intermediary region up to the outlet.
