Abstract
Abstract A device to fit existing engines for the purpose of increasing compressed fuel-mixture pressure and promoting a compression ratio of the fuel-mixture in an engine to enable the fuel-mixture to burn more perfectly and the engine to works more efficiently. In the prior application of the same petitioner, titled "Pressure Addible Engine" with the same purpose to the invention but built in an unit engine which shall request people to throw the used engine away. In incentive of that, present invention modifies the prior invention into independent device unit, suitably fit to existing gasoline engine or diesel engine and makes the invention to be acceptable popularly.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
307 words
A device for fitting in a first socket communicating with a combustion space of an internal combustion engine for increasing the gas pressure in said combustion space when a fuel air mixture is combusted therein, said first socket being adapted to removably receive a combustion assisting member; said combustion space being defined between a portion of the internal surface of a combustion chamber and a power member sealingly fitted in the chamber for cyclical movement between a first position in which the volume of said combustion space is a minimum and a second position in which the volume of said combustion space is a minimum; said device comprising a housing defining an internal storage chamber for storing high pressure combusted gas, said housing having a portal formed in the walls of said storage chamber, said housing including an appendage having an outer surface adapted to be fitted into said first socket, a passage being formed in said appendage, one end of said passage terminating at said portal, the other end of said passage communicating with said combustion space; said appendage having a second socket formed therein for receiving said combustion assisting member so that said combustion assisting member communicates with said passage; and valve means for opening said portal when said power member is in said first position before combustion of said fuel air mixture to permit said high pressure combusted gas to flow into said combustion space to increase the total pressure in said combustion space during combustion of said fuel air mixture and for permitting said high pressure combusted gas to flow from said combustion space into said storage space immediately after said combustion, and for closing said portal after said combustion to trap said high pressure combusted gas in said storage chamber when said power member is moving between said first and second positions.
Claim 2
Independent Claim
307 words
A device for fitting in a first socket communicating with a combustion space of an internal combustion engine for increasing the gas pressure in said combustion space when a fuel air mixture is combusted therein, said first socket being adapted to removably receive a combustion assisting member; said combustion space being defined between a portion of the internal surface of a combustion chamber and a power member sealingly fitted in the chamber for cyclical movement between a first position in which the volume of said combustion space is a minimum and a second position in which the volume of said combustion space is a minimum; said device comprising a housing defining an internal storage chamber for storing high pressure combusted gas, said housing having a portal formed in the walls of said storage chamber, said housing including an appendage having an outer surface adapted to be fitted into said first socket, a passage being formed in said appendage, one end of said passage terminating at said portal, the other end of said passage communicating with said combustion space; said appendage having a second socket formed therein for receiving said combustion assisting member so that said combustion assisting member communicates with said passage; and valve means for opening said portal when said power member is in said first position before combustion of said fuel air mixture to permit said high pressure combusted gas to flow into said combustion space to increase the total pressure in said combustion space during combustion of said fuel air mixture and for permitting said high pressure combusted gas to flow from said combustion space into said storage space immediately after said combustion, and for closing said portal after said combustion to trap said high pressure combusted gas in said storage chamber when said power member is moving between said first and second positions.
Claim 3
Dependent Claim
41 words
A device as in claim 1 wherein said internal combustion engine comprises a spark ignition engine, said combustion assisting member comprising a spark plug for combusting said fuel air mixture, said second socket being adapted to fit therein said spark plug.
Claim 4
Dependent Claim
41 words
A device as in claim 1 wherein said internal combustion engine comprises a compression ignition engine, said combustion assisting member comprising means for injecting fuel into said combustion space, said second socket being adapted to fit therein said fuel injecting means.
Claim 5
Dependent Claim
40 words
A device as in claim 1 or claim 2 or claim 3 further comprising a resilient spring mounted auxiliary piston formed in said storage chamber for storing energy when said high pressure combusted gas is stored in said storage chamber.
Claim 6
Dependent Claim
33 words
A device as in claim 2 wherein said value means comprises means for synchronously opening said portal when said spark plug is sparking and for closing said portal when said sparking is discontinued.
Claim 7
Dependent Claim
89 words
A device as in claim 5 wherein said internal combustion engine further comprises a distributor, and said synchronously opening means comprises a valve member disposable over said portal and electromagnetic means, electrically connectable to said distributor when said distributor is supplying electrical power to said spark plug, for lifting said valve member off of said portal to open said portal, said high pressure combusted gas in said storage chamber forcing said plug onto said portal to close said portal when said electromagnetic means is electrically disconnected from said distributor.
Claim 8
Dependent Claim
38 words
A device as in claim 3 wherein said valve means comprises means for synchronously opening said portal when said injecting means is injecting fuel into said combustion space, and for closing said portal when said injecting is discontinued.
Claim 9
Dependent Claim
64 words
A device as in claim 7 wherein said engine comprises a hydraulic fuel supply system for supplying fuel to said fuel injecting means, said valve means comprising means, coupled to said fuel supply system, for hydraulically opening said portal when said system is supplying fuel to said injecting means and closing said portal when said system is not supplying fuel to said injecting means.
Claim 10
Dependent Claim
127 words
A device as in claim 8 wherein said hydraulically opening means comprises a cylinder, a piston sealingly movable in said cylinder between a first position in which the volume of a hydraulic space defined between the piston and a portion of the cylinder surface is a maximum and a second position in which the hydraulic space is a minimum, a valve member disposable over said portal, a stem coupling piston and said valve member so that said valve member is lifted off said portal to open said portal when said piston is moved from said first position toward said second position, and means, coupling said fuel supplying system to said hydraulic space, for delivering fuel to said hydraulic space to lift said piston and said valve member.
