Patent ID: 7942139

Claim:
A ring insert that provides for an increase in air flow leading to a correlating increase in fuel efficiency for an internal combustion engine that is placed into a throttle body before a butterfly in a gas powered engine or at an intake tube or right before said intake tube in a diesel engine comprising: a body having an outer surface and an inner surface, a portion of said outer surface adapted to be inserted within an air intake conduit, said body having a forward edge and a rearward edge, said forward edge being roundly contoured at an angle between 45 and 90 degrees; and said inner surface including an annular surface in the shape of a truncated cone defining an annular inclined surface that is narrower at said forward edge than at said rearward edge forming a venturi directly adjacent said rearward edge said inner surface having a completely smooth and ungrooved surface thereby providing for laminar flow and reducing turbulence so that as air is forced through said body from said forward edge to said rearward edge the air is compressed increasing the velocity of the air and decreasing the pressure of the air, said air compression and decrease in pressure being caused by the vacuum created by said roundly contoured forward edge.
