Abstract
Abstract A method and apparatus for improving the performance and efficiency of a two-cycle internal combustion engine are described wherein the backflow combustion mixture gasses are captured at the reed valve and directed through a uni-directional passageway and injected back into the incoming air stream in the incoming air boot ahead of the carburetor so that the proper air-to-fuel mixture may be maintained by the carburetor. Recirculation of the backflow combustion mixture gasses as mentioned above increases the performance and the efficiency of a two-cycle internal combustion engine.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
132 words
An apparatus adapted to be used in the intake system of an internal combustion engine, said apparatus comprising in combination: flow pickup means for capturing and directing of backflow combustion mixture gasses; primary passageway means for connection of flow pickup means with uni-directional means; uni-directional flow means connected to said primary passageway means and to a secondary passageway means to prevent flow of gasses other than from said primary passageway means to said secondary passageway means; secondary passageway means for connection of said uni-directional flow means with a flow injector means; and flow injector means for redirection of the captured backflow combustion mixture gasses back into the intake air boot, said apparatus forming a closed loop between said flow pickup means and flow injector means with no openings to or from atmosphere.
Claim 2
Independent Claim
132 words
An apparatus adapted to be used in the intake system of an internal combustion engine, said apparatus comprising in combination: flow pickup means for capturing and directing of backflow combustion mixture gasses; primary passageway means for connection of flow pickup means with uni-directional means; uni-directional flow means connected to said primary passageway means and to a secondary passageway means to prevent flow of gasses other than from said primary passageway means to said secondary passageway means; secondary passageway means for connection of said uni-directional flow means with a flow injector means; and flow injector means for redirection of the captured backflow combustion mixture gasses back into the intake air boot, said apparatus forming a closed loop between said flow pickup means and flow injector means with no openings to or from atmosphere.
Claim 3
Dependent Claim
24 words
An apparatus according to claim 1, wherein said passageway means may be adjusted in length to vary the frequency of operation of the apparatus.
Claim 4
Dependent Claim
37 words
An apparatus according to claim 1, wherein said flow pickup means is inserted into the intake manifold ahead of the reed valve and positioned so that all backflow gasses will be captured by said flow pickup means.
Claim 5
Dependent Claim
40 words
An apparatus according to claim 1, wherein said flow injector means is inserted into the incoming air boot ahead of the carburetor and positioned so that the recirculated backflow gasses will merge with the incoming air stream entering the carburetor.
Claim 6
Independent Claim
73 words
A method of improving the performance and efficiency of a two-cycle internal combustion engine, said method comprising the steps of: capturing backflow combustion mixture gasses at closed reed valve and directing gasses through a uni-directional passageway assembly back into incoming air boot ahead of the carburetor; and adjusting the length of the uni-directional passageway assembly so that the frequency matches the frequency of the engine to maximize performance and efficiency of the engine.
Claim 7
Independent Claim
73 words
A method of improving the performance and efficiency of a two-cycle internal combustion engine, said method comprising the steps of: capturing backflow combustion mixture gasses at closed reed valve and directing gasses through a uni-directional passageway assembly back into incoming air boot ahead of the carburetor; and adjusting the length of the uni-directional passageway assembly so that the frequency matches the frequency of the engine to maximize performance and efficiency of the engine.
