Claims
- 1. An electronically controlled fuel injector for an internal combustion engine having combustion chambers and cmprising:
- an unthrottled air intake;
- first means for injecting the fuel into a given combustion chamber;
- second means for igniting said fuel before it enters said given combustion chamber, so that said fuel is burning as it enters said combustion chamber; and
- third means for electronically controlling the output power of the engine by electronically regulating the quantity of fuel injected during each injection of fuel into said given combustion chamber.
- 2. The electronically controlled fuel injector for an internal combustion engine as set forth in claim 1 wherein said first mens for injecting fuel into said given combustion chamber comprises:
- hydraulic means for initiating fuel injection into said given combustion chamber; and
- hydraulic means for terminating fuel injection into said given combustion chamber.
- 3. A method for injecting fuel into the combustion chambers of an electronically controlled fuel injector type internal combustion engine having pistons and combustion chambers, comprising the steps of:
- providing for unthrottled air intake during the piston's air intake stroke;
- injecting the fuel into a given combustion chamber;
- igniting the fuel before it enters into said given combustion chamber, so that said fuel is burning as it enters said combustion chamber; and
- electronically controlling the output power of the engine by electronically regulating the quantity of fuel injected into said given combustion chamber during each injection of fuel into said given combustion chamber.
- 4. A method for injecting fuel into the combustion chambers of an electronically controlled fuel injector type internal combustion engine having pistons and combustion chambers, comprising the steps of:
- providing for unthrottled air intake during the piston's air intake stroke;
- providing an electrically heated venturi tube incorporated into the injector of each said combustion chamber;
- injecting the fuel through each said heated venturi tube and into its associated said combustion chamber;
- igniting said injected fuel in said heated venturi tube;
- burning said injected fuel in said venturi tube and as it is injected into said given combustion chamber; and
- electronically controlling teh output power of the engine by regulating the quantity of fuel injected into said given combustion chamber during each injection of fuel into said given combustion chamber.
- 5. An electronically controlled fuel injector for an internal combustion engine having combustion chambers and comprising:
- an unthrottled air intake;
- first means for injecting the fuel into a given combustion chamber;
- second means for burning said fuel as it enters said given combustion chamber, said second means for burning said fuel comprising a hot-throated venturi device which ignites said fuel before it enters said given combustion chamber;
- third means for electronically controlling the output power of the engine by electronically regulating the quantity of fuel injected during each injection of fuel into said given combustion chamber.
- 6. The electronically controlled fuel injector for an internal combustion engine as set forth in claim 5 wherein aid hot-throated venturi device is an electrically heated venturi tube.
- 7. An electronically controlled fuel injector for an internal combustion engine having combustion chambers and comprising:
- an unthrottled air intake;
- first means for injecting the fuel into a given combustion chamber, said first means comprising:
- a fuel injector rod;
- a plurality of closely-spaced, open-ended cylinders, said cylinders being positioned concentrically around said injector rod so as to form a plurality of enclosed spaces between said open-ended cylinders;
- electro-rheological fluid contained within said spaces between said open-ended cylinders;
- a concentric baffle cylinder ring, for dividing said space between said open-ended cylinders into entrance and exit paths for said electro-rheological fluid;
- a hydraulic pump for pressurizing said electro-rheological fluid;
- a source of electric voltage for solidifying said electro-rheological fluid between adjacent open-ended cylinders, causing said fuel injector rod to move downward and thereby start fuel injection; and
- spring means which act to move said fuel injector rod upward in preparation for the next cycle of operation when said solidifying voltage is removed from said open-ended cylinders; and
- second means for burning said fuel as it is being injected into said given combustion chamber; and
- third means for switching on said soure of electric voltage and for electronically controlling the output power of the engine by electronically regulating the quantity of fuel injected during each injection of fuel into said given combustion chamber.
- 8. an electronically controlled fuel injector for an internal combustion engine having combustion chambers and comprising:
- an unthrottled air intake;
- first means for injecting the fuel into a given combustion chamber, said first means comprising:
- a fuel injector rod;
- a plurality of closely-spaced, open-ended cylinders, said cylinders being positioned concentrically around said injector rod so as to form a plurality of enclosed spaces between said open-ended cylinders, said enclosed spaces defining an inlet passage and an outlet passge;
- electro-rheological fluid within said spaces between said open-ended cylinders;
- a concentric baffle cylinder ring, for dividing said spaces between said open-ended cylinders into entrance and exit paths for said electro-rheological fluid;
- a hydraulic pump for pressurizing said electro-rheological fluid;
- a first source of electric voltage, for solidifying said electro-rheological fluid in said inlet passage between adjacent open-ended cylinders, causing said fuel injector rod to move downward and thereby start fuel injection; and
- a second source of electric voltage switched on as said first source is switched off, for solidifying said electro-rheological fluid in said outlet passage between adjacent open-ended cylinders, causing said fuel injector rod to move upward in preparation for the next cycle of operation; and
- second means for burning said fuel as it is being injected into said given combustion chamber; and
- third means for sequentially switching on both said sources of electric voltage and for electronically controlling the output power of the engine by electronically controlling the switching time, thereby regulating the quantity of fuel injected during each injection of fuel into said given combustion chamber.
