Claim 3

A device as claimed in claim 1, wherein said size of each said space means is non-adjustable.

Claim 4

A device as claimed in claim 1, wherein the sum of the total area of said space means does not exceed 30% of the total air intake area for the carburetor.

Claim 5

A device as claimed in claim 1, wherein said space means comprise spaced slots.

Claim 6

A device as claimed in claim 4, wherein each said slot has a width of less than 1 mm.

Claim 7

A device as claimed in claim 1, wherein said member comprises a plurality of spaced plates each having a center opening therethrough, and said space means comprise slot-shaped spaces between adjacent said plates, said slot-shaped spaces being of equal size and extending peripherally around the intake passage.

Claim 8

A device as claimed in claim 6, wherein the width of each said slot-shaped space formed between adjacent said plates is less than 1 mm.

Claim 9

A device as claimed in claim 1, wherein said member comprises a cylindrical wall member, and said space means comprise a plurality of holes extending through said wall member.

Claim 10

A device as claimed in claim 8, wherein said holes are substantially uniformly distributed around the periphery of said wall member.

Claim 11

A device as claimed in claim 8, wherein each said hole is substantially round and has a diameter less than 1 mm.

Claim 12

A device as claimed in claim 1, wherein said member comprises a cylindrical body made of porous material, and said space means comprise pores in said body.

Claim 13

In an internal combustion engine of the type including combustion chambers, a carburetor, an intake passage extending between said carburetor and said combustion chambers for passing an air-gas mixture therebetween, and means for introducing additional air into said mixture flowing through said intake passage, the improvement wherein said additional air introducing means comprises: a member mounted between said carburetor and said combustion chambers; said member having extending therethrough a center opening forming a portion of said intake passage, said center opening being no greater in size than said intake passage; a plurality of space means, extending through said member peripherally of said center opening, for communicating the atmosphere with said center opening and for thus introducing additional air from the atmosphere to said air-gas mixture in said intake passage; and each said space means having a size below that critical value which would allow the additional air passing therethrough to cause cross turbulence in said air-gas mixture passing through said intake passage.

Claim 14

In an internal combustion engine of the type including combustion chambers, a carburetor, an intake passage extending between said carburetor and said combustion chambers for passing an air-gas mixture therebetween, and means for introducing additional air into said mixture flowing through said intake passage, the improvement wherein said additional air introducing means comprises: a member mounted between said carburetor and said combustion chambers; said member having extending therethrough a center opening forming a portion of said intake passage, said center opening being no greater in size than said intake passage; a plurality of space means, extending through said member peripherally of said center opening, for communicating the atmosphere with said center opening and for thus introducing additional air from the atmosphere to said air-gas mixture in said intake passage; and each said space means having a size below that critical value which would allow the additional air passing therethrough to cause cross turbulence in said air-gas mixture passing through said intake passage.

Claim 15

The improvement claimed in claim 12, wherein said size of each said space means is non-adjustable.

Claim 16

The improvement claimed in claim 12, wherein the sum of the total area of said space means does not exceed 30% of the total air intake area for said carburetor.

Claim 17

The improvement claimed in claim 12, wherein said space means comprise spaced slots.

Claim 18

The improvement claimed in claim 15, wherein each said slot has a width of less than 1 mm.

Claim 19

The improvement claimed in claim 12, wherein said member comprises a plurality of spaced plates each having a center opening therethrough, and said space means comprise slot-shaped spaces between adjacent said plates, said slot-shaped spaces being of equal size and extending peripherally around said intake passage.

Claim 20

The improvement claimed in claim 17, wherein the width of each said slot-shaped space formed between adjacent said plates is less than 1 mm.

Claim 21

The improvement claimed in claim 12, wherein said member comprises a cylindrical wall member, and said space means comprise a plurality of holes extending through said wall member.

Claim 22

The improvement claimed in claim 19, wherein said holes are substantially uniformly distributed around the periphery of said wall member.

Claim 23

The improvement claimed in claim 19, wherein each said hole is substantially round and has a diameter less that 1 mm.

Claim 24

The improvement claimed in claim 12, wherein said member comprises a cylindrical body made of porous material, and said space means comprise pores in said body.
