Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
97 words
In a method of feeding magnesium powder into the air intake of an internal combustion engine including the step of variably regulating the rate of flow of the magnesium powder into the engine air intake and the step of variably regulating the rate of flow of the magnesium powder in accordance with the engine speed and load, the additional step of mixing the magnesium powder with water and agitating and heating the magnesium enriched water mixture with a flow of exhaust fumes diverted from the engine exhaust manifold and induced into the lower portion of the mixture.
Claim 2
Dependent Claim
97 words
In a method of feeding magnesium powder into the air intake of an internal combustion engine including the step of variably regulating the rate of flow of the magnesium powder into the engine air intake and the step of variably regulating the rate of flow of the magnesium powder in accordance with the engine speed and load, the additional step of mixing the magnesium powder with water and agitating and heating the magnesium enriched water mixture with a flow of exhaust fumes diverted from the engine exhaust manifold and induced into the lower portion of the mixture.
Claim 3
Dependent Claim
28 words
The method as in claim 1, including the step of variably regulating the rate of exhaust gas fumes induced into the magnesium mixture for agitation and heat absorption.
Claim 4
Dependent Claim
35 words
The method as in claim 2, including the step of maintaining an atmospheric pressure within the magnesium containing vessel by venting the vessel for the removal of any non-condensible exhaust fumes discharged into the vessel.
Claim 5
Dependent Claim
37 words
The method as in claim 3, including the step of venting the non-condensible exhaust fumes released within the vessel for the discharge of the vented gases into a low pressure downstream section of the engine exhaust system.
Claim 6
Dependent Claim
47 words
A method as in claim 4, including the step of mingling the free carbon soot particle content of the exhaust fumes with the mixture via a submerged perforated section of an exhaust gas delivery conduit and allowing the carbon soot particles to adhere to the magnesium particles.
Claim 7
Dependent Claim
26 words
The method as in claim 5, including the step of additionally drawing into the engine intake air flow stream a variable regulated flow of magnesium-powder-soot-water mixture.
Claim 8
Dependent Claim
27 words
The method as in claim 6, including the step of enhancing the action with a predetermined variable amount of emulsifiable colloidal graphite powder within the magnesium-soot-water mixture.
Claim 9
Dependent Claim
26 words
The method as in claim 7, including the step of formulating the magnesium powder content portion of the induced water mixture for maximum in-cylinder magnesium-steam reaction.
Claim 10
Dependent Claim
42 words
The method as in claim 8, including the step of adding to the magnesium-water mixture a sufficient quantity of exhaust soot particles for maximum in-cylinder gas bombardment of hot incondensible carbon-soot to ignite all combustible gases not ignited by the magnesium-steam reaction.
Claim 11
Dependent Claim
36 words
The method as in claim 9, including the step of incorporating into the water-magnesium-soot mixture sufficient emulsifiable colloidal graphite for the adequate in-cylinder-piston wearing surface lubrication under the increased temperature-pressure environment of the magnesium-steam carbon reactions.
Claim 12
Dependent Claim
52 words
The method as in claim 10, including the step of storing a variable quantity of preblended magnesium powder and emulsified colloidal graphite water mixture for automatic feed into the mixture and the exhaust gas heating-bubble agitating dispensing chamber as such heated agitated mixture is dispensed into the engine air intake flow stream.
Claim 13
Dependent Claim
69 words
The method as in claim 11, including the step of injecting into the engine air-intake, a water-base mixture, fortified with sufficient magnesium powder content for maximum in-cylinder steam-magnesium reaction resulting from the formulation of the mixture, but also modified sufficiently and accordingly to supplement the need of either water or magnesium content required for maximum magnesium-steam fire reaction explosion, when the engine is fed a magnesium treated fuel intake.
