Abstract

Abstract My invention relates to internal combustion engines and its main objects are to provide improved combustion, fewer exhaust emissions, with less fuel consumption. It relates particularly to the intake manifold, where by properly positioning my device, a more efficient, catalyzed, fuel mixture is produced, resulting in exhaust emissions well below established standards, and a substantial increase in miles per gallon of fuel.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 169 words
In combination with an internal combustion engine having an intake manifold, a device located upstream of the intake manifold for conveying combustibles into said manifold, said device comprising: a plurality of tubular members having imperforate walls arranged concentrically about a common axis; and means mounting said tubular members so that one end of each tubular member extends through a side wall of the manifold, the lengths of each tubular member being such that said one end of each tubular member extends into the manifold a different distance with the outermost of said tubular members extending into the manifold the smallest distance, the innermost of said tubular members extending into the manifold the largest distance and any intermediate tubular members extending into the manifold by intermediate distances, said device being arranged so that the combustibles flow through the innermost tubular member and the spaces between the walls of the adjacent ones of said tubular members and then transverse to said one end of said tubular members upon entering the manifold.
Claim 2
Dependent Claim 169 words
In combination with an internal combustion engine having an intake manifold, a device located upstream of the intake manifold for conveying combustibles into said manifold, said device comprising: a plurality of tubular members having imperforate walls arranged concentrically about a common axis; and means mounting said tubular members so that one end of each tubular member extends through a side wall of the manifold, the lengths of each tubular member being such that said one end of each tubular member extends into the manifold a different distance with the outermost of said tubular members extending into the manifold the smallest distance, the innermost of said tubular members extending into the manifold the largest distance and any intermediate tubular members extending into the manifold by intermediate distances, said device being arranged so that the combustibles flow through the innermost tubular member and the spaces between the walls of the adjacent ones of said tubular members and then transverse to said one end of said tubular members upon entering the manifold.
Claim 3
Dependent Claim 42 words
The combination as defined in claim 1 wherein the common axis is substantially perpendicular to a wall of the manifold to create cross flow turbulence by passage of the combustibles across the ends of the tubular members which extend into the manifold.
