DETAILED DESCRIPTION OF THE INVENTION

[0019] In a general manner, the device of the present invention is installed in the engines of automotive vehicles, by the fuel entry, in general at the front part of the vehicle, up to the beginning of the injector nozzle flute. The device in question consists basically of a casing (6) which comprises internally arranged at least one resistor (4), which involves at least one tube (5). The resistor (4) is connected to a central circuit (1), which communicates with temperature sensors (2) and with a control circuit (3). The temperature sensors (2) are installed, preferably at the entry and exit of the casing (6).

[0020] The solution foresees that there can be used hose couplings similar to the ones currently used in vehicles or any other equivalent or similar fixation and sealing means. In this manner, before the fuel enters the fuel injection system of the vehicle, the same goes through the copper transformation chamber. This step of the course allows the fuel to suffer a chemical molecular reaction which modifies a part of the same, thus increasing the supply combustion energy capacity.

[0021] Thus, from the installation of the device in the automotive vehicle, the internal system of the same executes an inductive thermal exchange in the fuel, making the hydrogen, which is present in the fuel itself, release from the water that is present in its composition. Thus, the quantities of hydrogen present in the fuel water, which would then be dispatched via the exhaust pipe, are joined to the fuel by the induction reaction generated in the device. This induction reaction, provides higher capacity of energy combustion and, consequently, a more homogeneous burning. The device thus allows a controlled temperature change, which allows the fuel to reach a higher fuel quality, making the internal combustion engine not consume so much fuel and maintain the high performance. That is, this increase in the fuel energy capacity occurs by an inductive heating caused in the fuel, due to the variation of the low voltage electric charges which vary from 10 to 14V and induced amperage from 8 to 12.sup.a. Preferably, the device submits the fuel to low voltage 12V electric charges and 10 A amperage in the resistor (4).

[0022] The device carries out this molecular reaction by means of the temperature increase between 60° C. and 80° C. More specifically, the increase in temperature can vary from 65 to 69° C. in gasoline, 70 to 73° C. in ethanol, and between 64 to 70° C. in the diesel oil. The fuel temperature is controlled by a central circuit (1), which communicates with temperature sensors (2) installed at the entry and exit of the device, and with a control circuit (3) that is responsible for the control of the temperature increase. The maximum temperature of each fuel is calculated from the Hydrogen burning temperature, which is of 73° C. and from the quantity of oxygen in the fuel. In case the temperature exceeds 73° C., there is the risk of losing fuel quality, which may increase the consumption of the engine. To avoid this loss, the device counts on temperature sensors (2) in direct communication with the central circuit (1) which can turn off and interrupt the current in the resistor (4) in case the temperature gets close to the limit defined in the control circuit (3) of the present invention.

[0023] The central circuit (1) is comprised by at least one PIC board, which is fed by the battery of the vehicle, whereby the said PIC board sends pulses to the relays of the control circuit (3), sending the necessary amperage to feed the resistor (4). Moreover, based on the information provided by the temperature sensors (2), the central circuit (1) controls the amperage level which passes to the control circuit (3).

[0024] However, it is possible that the control circuit (3) receives the current directly from the vehicle battery, being capable of controlling the level of current which passes to the resistor (4) by means of pulses emitted from the central circuit (1). To this end, the control circuit (3) must be comprised by control relays, enabling the control of the passage of the current to the resistor (4) by means of the pulses received from the central circuit (1). That is, the control relays can control the quantity of amperage sent to the resistor (4). In this way, the amperage received by the resistor (4) is controlled, and may vary from 8 to 12 A.

[0025] To be able to control the temperature by means of the current increase, the temperature sensor (2) located at the entry sends the entry temperature of the fuel to the central circuit (1), and the temperature sensor (2) located at the exit of the device sends to the central the temperature at which the fuel is exiting the device. With this information, the central circuit (1), communicates, via pulses, with the relays of the control circuit (3), defining the quantity of current in the resistor (4) which is necessary to maintain the fuel at the ideal temperature.

[0026] The resistor (4) heats a tube (5) having from 8 to 12 mm diameter, through which the fuel passes and suffers the molecular reaction. With the purpose of avoiding waste, the resistor (4) also presents a thermal blanket (not shown), surrounding the set and avoiding loss of heat. The resistor (4) has a length that can vary between 5 and 10 cm to fully execute the molecular reaction in the fuel.

[0027] The resistor (4) is responsible for the increase in temperature, which can vary between 60° C. and 80° C., of the fuel that passes through the tube (5). With this temperature increase, the fuel suffers the molecular reaction, wherein the hydrogen in the water that is present in the fossil fuels distributed by the refineries is released from the oxygen, forming pure “H” hydrogen. This pure “H” hydrogen, reacts with the gasoline, ethanol or diesel inside the device. In this case, the combustion energy of the device is optimized, since the “H” hydrogen released from the water of the fuel is the element having larger charge to cause the explosion of the input, increasing the yield thereof. This being so, to increase the yield, the number of hydrogens from the fossil fuel used is increased, increasing the octane rating of the fuel generating a better burn.

[0028] Portuguese Description

[0029] With this induction, for example, the gasoline of structural formula C8H18 comes to comprehend a larger number of hydrogen molecules in the structural composition thereof. That is, with the molecular reaction with the pure “H” hydrogen generated, the fuel goes from C8H18 to C8H36, thus characterizing a more powerful fuel and requiring less consumption by the engine.

[0030] Finally, it must be noted that the device is preferably installed at the fuel entry in the front part of the vehicle up to the beginning of the injector nozzles flute. For this purpose, the device counts on a universal coupling to be able to be installed in any automotive vehicle.
