Abstract

Abstract A valve controlled disposable container, bracket mounted on the fire wall of an internal combustion vehicle for a selective feeding of a composition comprising a mixture of 90% hydrogen peroxide, 9% water, 0.5% nitro methane and 0.5% methanol to the intake manifold or carbureter of the engine. The present invention generally relates to internal combustion engine operation, and is more specifically concerned with a system for increasing the operational efficiency thereof through the utilization of apparatus which enables the selective feeding of an engine additive uniquely adapted to effect a substantial reduction in pollutant in conjunction with an appreciable reduction in gas consumption. One of the major problems facing the auto industry at the present time is the necessity of finding effective pollution reduction means. While many systems have been proposed, and in fact put into operation, the basic deficiency with such systems is the resulting substantial increase in gas consumption. Accordingly, it is a primary object of the present invention to provide a unique system of pollution control which, in operation, actually results in an appreciable decrease in normal gas consumption. In conjunction with the above, it is also an important object of the invention that the system be economical, easily installed and requires no modification of the engine construction other than the attachment of a bracket to the fire wall and the discharge end of a hose to feed into the carbureter or intake manifold. In achieving the objects of the invention, the apparatus includes a bracket affixed to the fire wall of an engine compartment and releasably mounting an elongated container between upper and lower head and foot pieces. The container is retained by upper and lower pairs of spring arms. An elongated feed hose is removably coupled to an outlet nozzle on the bottom of the container with the second end of the hose coupled to the engine at any appropriate place for the introduction of the additive from the container. In order to enable a proper feeding of the additive, a selectively operable vent cap is mounted on the lower end of the container and communicated with the upper interior thereof through an elongated vent tube. The additive itself is highly significant and comprises a mixture of 90% hydrogen peroxide, 9% water, 0.5% nitro methane and 0.5% methanol. These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 243 words
In combination with an internal combustion engine of the type having a reduced pressure combustible mixture induction system, an additive supply assembly including a container, a quantity of liquid additive in the container, and a conduit communicating the container with the induction system for supplying additive thereto, that improvement comprising the arrangement in which said conduit is connected to the bottom of said container, said container including an air inlet in the bottom thereof, an air inlet tube extending upwardly from the air inlet to a point adjacent to the top of the container, said air inlet including a control valve to control inlet of air into said container for controlling the pressure therein thus controlling the outflow of additive through the conduit, said container being constructed of substantially unbreakable plastic material and disposable after use, said container also being in the form of an elongated cylinder with generally flat top and bottom ends, and a bracket mounting said container vertically by engaging the top, bottom and peripheral wall thereof, said top end of the container having a notch extending diametrically thereof, said bracket having horizontally disposed tongues frictionally engaging the ends of the container with the upper tongue received in the notch, said bracket including resilient clips engaging the central portion of the peripheral wall of the container, said air inlet and conduit being offset from the center of the bottom of the container to facilitate the reception of the bottom tongue.
Claim 2
Dependent Claim 243 words
In combination with an internal combustion engine of the type having a reduced pressure combustible mixture induction system, an additive supply assembly including a container, a quantity of liquid additive in the container, and a conduit communicating the container with the induction system for supplying additive thereto, that improvement comprising the arrangement in which said conduit is connected to the bottom of said container, said container including an air inlet in the bottom thereof, an air inlet tube extending upwardly from the air inlet to a point adjacent to the top of the container, said air inlet including a control valve to control inlet of air into said container for controlling the pressure therein thus controlling the outflow of additive through the conduit, said container being constructed of substantially unbreakable plastic material and disposable after use, said container also being in the form of an elongated cylinder with generally flat top and bottom ends, and a bracket mounting said container vertically by engaging the top, bottom and peripheral wall thereof, said top end of the container having a notch extending diametrically thereof, said bracket having horizontally disposed tongues frictionally engaging the ends of the container with the upper tongue received in the notch, said bracket including resilient clips engaging the central portion of the peripheral wall of the container, said air inlet and conduit being offset from the center of the bottom of the container to facilitate the reception of the bottom tongue.
Claim 3
Dependent Claim 114 words
The combination as defined in claim 1 wherein said conduit includes a flexible section, and opposed clamp plates for adjustably clamping the flexible section for restricting flow through the conduit, said conduit including a tee fitting at the end thereof remote from the container, said induction system of the engine including a conduit interconnecting a PCV valve and a carburetor assembly on the engine with the tee fitting on the conduit incorporated therein with the air inlet valve being adjusted to eliminate adverse affects upon flow of crankcase emissions from the PCV valve to the carburetor assembly, said liquid additive comprising a mixture of 90% hydrogen peroxide, 9% water, 0.5% nitromethane and 0.5% methanol.
