Abstract:
1. An intake tubing for an engine comprising: a tubular member including a chamber formed therein and defined by an inner peripheral surface, and including a plurality of helical protuberances and a plurality of helical grooves formed therein, said tubular member including an inlet end for receiving fluid, and an outlet end for coupling to the engine, and including a first flared member extended from said inlet end thereof, and said first flared member including an inner peripheral surface tapered conically from an outer opening with a greater diameter to an inner opening with a smaller diameter, said inner opening of said first flared member including an inner diameter greater than that of said inlet end of said tubular member, to form a peripheral shoulder between said tubular member and said first flared member, and said helical protuberances and said helical grooves of said tubular member being provided to guide the fluid to flow through said chamber of said tubular member in great speed when the fluid is supplied in great speed toward said inlet end of said tubular member, and to generate eddy current and to lower the fluid to flow through said chamber of said tubular member when the fluid is supplied in low speed toward said inlet end of said tubular member.
