[0020] Technical problem to be solved by the present invention is to provide a device and fast assistant, which will accelerate ignition process, improve hydrocarbon combustion and prevent detonation, burning coke, in order the engine produces maximum efficiency, and saves gasoline consumption and reduces exhaust emissions.

[0021] These objects are achieved through a combined device comprising energetic nanoparticles which are found to be producing a very effective synergistic outcome if they are used together to modify a liquid fuel before usage in a combustion chamber. The system mentioned above is aimed to be used in any combustion chamber like internal combustion engine utilizing of liquid fuels, particularly of gasoline. The system can be placed on any component in a fuel supplying assembly such as the conduits, fuel pumps, filters and in a place before/after mixing chambers such as fuel injectors or carburetors.

[0022] Energetic nanoparticles according to the present invention are provided as a mixture of the oxides of the elements comprising Titanium, Silica and Aluminum. The oxides of titanium, silica and aluminum comprised in the coating as described herein are titanium oxide (TiO.sub.2), silicon oxide (SiO.sub.2) and alumina (Al.sub.2O.sub.3), respectively. In the context of the present invention, the term nanoparticle refers to small particles having a particle size less than 100 nm and more particularly between 10 and 100 nm. The proportion of each oxide in the mixture can be in amounts ranging between 0.01% to 99.00% to produce the desired effect. Such proportions can be arranged depending on the fuel type or costs of the oxides independently.

[0023] The inventor of the current invention unexpectedly found that the energetic nanoparticles as defined hereinabove behave as a catalyst if they are used in a thin epoxy coating layer. Said epoxy coating layer may comprise conventional epoxy resins and curing agents. Alternatively, epoxy paint coating compositions can be utilized in the present invention.

[0024] The catalyzing effect of the nanoparticles greatly enhances breaking down of the fuel molecules and reorganization thereof especially in a flowing fuel system by virtue of the passivated oxide layers characterized by a high rate of energy release. In particular, energetic nanoparticles offer a high volumetric heat of oxidation, enabling transportation of more energy per given fuel volume. They generally exhibit faster ignition timescales due to the dramatic increase in the surface-to-volume ratio, and can ignite below the bulk melting point of the metal due to rapid temperature gradients through their thin oxide layers. Nano-sized energetic particles offer the potential of controlled burning rates, increased combustion efficiencies, and reduced sensitivity. Therefore, the nanoparticles according to the present invention are arranged in a device in fluid communication with the liquid fuel. Due to this direct contact with the fluid, catalyzing effect is directly transferred to the fuel molecules without the limitations of the systems in prior art Therefore, the nanoparticles are provided in powder form which are mixed in an epoxy carrier for producing a coating. Thereafter, the coating is applied onto a surface of a device through which a liquid fuel comes into contact. The device can be embodied as a conduit, fuel pump, filter or any other component of the vehicle or engine which comes into contact with the liquid fuel before entering into the combustion chamber.

[0025] The nanoparticles according to this invention do not dissolve in hydrocarbon fuel, and therefore they offer a long term run in a particular device such as a conduit, fuel pump or fuel filter as mentioned above.

[0026] In another aspect, the present invention pertains to a method for preparing fuel saving device for a combustion chamber comprising the steps of preparing nanosized particles of TiO.sub.2, SiO.sub.2 and Al.sub.2O.sub.3, mixing the same with an epoxy coating composition homogenously and applying the resulting composition onto a surface in the fuel passageway of the device.

[0027] The inventor of the present invention has surprisingly found that the combined system according to the instant invention can produce the effects of making combustion almost complete (with unburned hydrocarbon less than 20 ppm), lowering gas consumption up to 95%, burning out carbon deposit, reducing gas pollution especially carbon monoxide (CO) which is reduced down to 0.0%, and increasing engine performance drastically.

EXAMPLES

[0028] The following examples are put forth so as to provide those of ordinary skill in the art with a complete disclosure and description of how the compounds, compositions, articles, devices and/or methods claimed herein are made and evaluated, and are intended to be purely exemplary of the invention and are not intended to limit the scope of what the inventors regard as their invention. However, those of skill in the art should, in light of the present disclosure, appreciate that many changes can be made in the specific embodiments which are disclosed and still obtain a like or similar result without departing from the spirit and scope of the invention.

[0029] Efforts have been made to ensure accuracy with respect to numbers (e.g., amounts, temperature, etc.), but some errors and deviations should be accounted for. Unless indicated otherwise, parts are parts by weight, temperature is in C. or is at ambient temperature, and pressure is at or near atmospheric.

[0030] A mixture of TiO.sub.2, SiO.sub.2, and Al.sub.2O.sub.3 was provided with a particle size arrangement between 10 and 100 nm. The nanoparticles were then loaded into an epoxy carrier and mixed homogenously. The mixture was coated onto the inner surface of tubular fuel conduits supplying gasoline to the fuel injectors in automobiles of different brands.

[0031] Automobiles of different brands were also provided with regular fuel conduits each of which have been tested on a test road in identical conditions with constant speed, and fuel consumptions of the same have been recorded. The fuel conduits of the same vehicles were then replaced with the fuel conduits having active coating layer as mentioned above. After the testing procedure in identical conditions, fuel consumption values have been recorded and compared with the previous values.

[0032] The test road was a 50 miles street without traffic and any cause of slowing and acceleration. The fuel tanks of the vehicles have been filled up in the beginning of each test and filled up again at the end of the tests. The latter gave the fuel consumption values for each test.
