Description

TECHNICAL FIELD [0001] The present invention relates to an exhaust gas and a fuel saving device for an internal combustion engine,

The present invention relates to an exhaust gas and a fuel saving device for an internal combustion engine, and more specifically, by supplying hydrogen produced through an electrolytic bath to an engine combustion chamber or the like, adsorbed carbon residue, carbon sludge and the like can be removed, And to an exhaust gas and fuel saving device of an internal combustion engine capable of improving combustion efficiency.

Pure water without any foreign substance is composed of one oxygen (O) and two hydrogen (H). Generally, when electrolysis of such water, oxygen and hydrogen are separated and each gas is generated.

At this time, oxygen and hydrogen are generated at a ratio of 1: 2, and a mixed gas containing oxygen and hydrogen can be used as a non-polluting energy source or fuel.

On the other hand, a vehicle is a vehicle in which a liquid fuel such as petroleum or gasoline, which is a kind of fossil fuel, is mixed with air at a predetermined ratio and is gasified, the kinetic energy generated in the process of injecting or supplying into the combustion chamber of the engine room, .

Since the vehicle uses a battery that outputs a voltage of 12 volts (V) or 24 volts (V), the amount of voltage and current that can be supplied from the vehicle is relatively limited.

At this time, since the mixing ratio of the liquid fuel and the air is adjusted to the optimal state, the combustion efficiency of the fuel can be increased and the fuel efficiency of the vehicle can be improved. Therefore, in order to find the optimal mixing ratio of liquid fuel and air, many researches and developments have been carried out, but it has reached a certain limit.

As a conventional technique capable of generating a mixed gas of hydrogen and oxygen by electrolysis and supplying the generated mixed gas to the vehicle, Hydrogen mixed gas generator ', so that detailed explanation will not be given.

The conventional technique does not solve the problem of generating heat because rust occurs in the electrode plate and a separate fan is used to cool the heat generated in the electrolyte.

When rust is generated on the electrode plate, no gas is generated because it is not electrolyzed. When heat is generated, the mixed gas is not generated and the electrolytic solution evaporates. The evaporated water vapor is supplied to the engine room of the vehicle instead of the mixed gas, There is a problem that can give.

Further, the prior art uses a fan to cool the generated heat, thereby accelerating the discharge of the battery, thereby shortening the life of the battery.

Therefore, it is necessary to develop a technique of generating a large amount of mixed gas by electrolysis in a vehicle, smoothly mixing the gas, and preventing the rusting of the electrode and the generation of heat in the electrolytic solution.

To solve such a problem, Korean Patent Registration No. 10-1147565 discloses a method for producing a mixed gas of hydrogen and oxygen by electrolysis by applying a positive voltage and a negative voltage to a positive electrode and a negative electrode respectively contained in an aqueous solution of sodium hydroxide A mixed gas generating apparatus comprising: a gas generating unit for electrolyzing an aqueous solution of sodium hydroxide to generate the mixed gas; A level converter for converting a voltage level applied from the car battery; And a constant current unit that receives a direct current voltage output from the level converter and generates a constant current to provide the constant current to the gas generating unit, wherein the gas generating unit includes a body portion having an internal accommodation space for accommodating an aqueous sodium hydroxide solution, ; A decomposition part installed in the internal space of the body part and contained in the aqueous solution of sodium hydroxide; An injection unit installed at one side of the upper end of the body part to introduce the sodium hydroxide aqueous solution; And a discharge unit for discharging the mixed gas generated at the other side of the upper part of the body part, wherein the decomposing part includes an insulator which is installed in the internal space of the body part; A positive electrode terminal and a negative electrode terminal provided on the insulator and flowing a constant current applied from the constant current unit; And a plurality of polar bodies which are wound in a spring form from the upper portion to the lower portion of the insulator and are connected to the positive electrode terminal and the negative electrode terminal while maintaining a constant distance from each other, have.

The above patent discloses that electrolysis of aqueous sodium hydroxide solution is a strong base and it is necessary to make or handle an aqueous solution of sodium hydroxide which is harmful to the human body and there is inconvenience and danger that dangerous materials are charged from time to time in the water tank.

In addition, since oxygen is supplied together with hydrogen, some of the supplied water may be converted to water to cause rust, and electrolysis efficiency is lowered as sodium is adhered to the cathode, which is inconvenient to replace . In addition, sodium is highly reactive and can present a fire or explosion hazard.

1 and 2, the exhaust gas and fuel saving device 100 of the internal combustion engine according to the present invention supplies hydrogen to one side of the air intake port 11 for supplying air into the engine 10, A water tank 110 disposed at one side of the casing 101, an electrolytic bath 130 for generating hydrogen, and a water supply unit 130 for supplying water from the water tank 110 to the electrolytic bath 130 A water supply part 140 for supplying water to the electrolytic bath 130 and a power supply part 150 for supplying power to the electrolytic bath 130 and one end communicating with the cathode chamber 133 of the electrolytic bath and the other end communicating with one side of the air suction port 11 And a hydrogen supply hose 154 for supplying hydrogen generated in the electrolytic bath 130 to the engine 10 into the engine 10.

Meanwhile, in FIG. 1B, in order to clearly see the core constitution of the present invention, some configurations, some or all of hoses or wires connecting the configurations are removed, unlike FIG. 1C.

The casing 101 accommodates and fixes all or a part of the electrolytic bath 130, the water supply unit 140 and the power supply unit 150. The casing 101 may be installed in a rear trunk of a passenger car.

The water tank 110 may be disposed in the casing 101 or on one side thereof, and serves to receive and supply water to be electrolyzed.

Referring to FIG. 2, the electrolytic cell 130 electrolyzes the supplied water. The electrolytic cell 130 includes an anode chamber 131 in which a cathode plate 132 is formed and oxygen is generated, a cathode plate 134, A cathode chamber 133 and a membrane member 135 disposed between the cathode plate 132 and the cathode plate 134 and partitioned into the cathode chamber 133 and the anode chamber 131.

The cathode chamber (133) and the anode chamber (131) have a mesh structure through which water can pass.

Since the water supplied to the anode chamber 131 is supplied to the cathode plate 134 due to the wettability of the membrane member 135, The positive electrode plate 132 is energized to be electrolyzed.

3, the water supply unit 140 includes a water suction hose 141 inserted into the water tank, a pump 142 connected to the water suction hose 141 to pump water in the water tank 110, An ion filter 143 connected to the pump 142, a water supply hose 144 for supplying water through the ion filter 143 to the cathode chamber 133, And a water discharge hose 145 for circulating water and oxygen in the water tank to the water tank. Here, the pump 142 and the ion filter 143 are connected by a connection hose 146.

The ion filter 143 ionizes water to facilitate electrolysis. Since the ion filter 143 corresponds to a known structure in the electrolysis field, detailed description thereof will be omitted.

4, the power supply unit 150 supplies the power of the automobile battery 13 to the electrolytic cell 130. The power supply unit 150 includes an earth leakage breaker 151 connected to the automobile battery 13, And a current amplifier 153 amplifying a part of the currents distributed in the distributor 152 and supplying the amplified current to the positive electrode plate 132 and the negative electrode plate 134, have. A heat dissipation fan 153a may be installed on one side of the current amplifier 153 to prevent overheating.

Here, the distributor 152 is divided into a plurality of electric wires, a part of which is directly connected to the pump 142, a water circulation pump 162 to be described later, and the other electric wires are connected to the electrolytic bath 130 through the current amplifier 153, Lt; / RTI > Here, the current amplifier 153 serves to lower the voltage of the automobile battery 13 and amplify the current. For example, a 12V, 7A automobile battery power source is supplied with 5V through the current amplifier, As a negative electrode plate and a positive electrode plate.

Thus, by lowering the voltage and amplifying the current, the electrolysis of water can be stably performed while reducing the amount of heat and energy consumption in the anode and cathode plates.

In the present invention, a plurality of electrolytic baths 130 may be provided in parallel. At this time, a plurality of current amplifiers 153 are also provided in parallel so as to correspond to the respective electrolytic baths 130.

The present invention may further include the water removing unit 160.

The water removing unit 160 prevents the water discharged through the hydrogen supply hose 154 from flowing into the engine together with the hydrogen generated in the cathode chamber 133, A water removing filter 161 connected to the water suction hose 141 to selectively transmit only hydrogen, and a moisture absorbing filter 161 for absorbing the moisture filtered by the water removing filter 161 and then circulating the water to the water suction hose 141 when the water is filled with a predetermined amount of water. And a circulation pump 162 can be exemplified.

The hydrogen supply hose 154 communicates with the air intake port 11 provided at one side of the engine and supplies hydrogen with moisture removed. The hydrogen acts as follows.

In the case of the engine combustion chamber, the low temperature of the cylinder wall partly incompletely combusts as shown in the following reaction equation (1).

C ₈ H ₁₈ + O ₂ ? CO + H ₂ O ????? (1)

Because of this incomplete combustion, the carbon residue is adsorbed to the engine combustion chamber, cylinder head, spark plug, etc. as shown in the following reaction formula (2), and this carbon residue causes abnormal exhaust gas emissions and more fuel consumption, .

C ₈ H ₁₈ + Heat → C (Carbon residue) + H ₂ + C _X H _Y --- Reaction formula (2)

Thus, the carbon residue adsorbed on the engine combustion chamber, the cylinder head, the spark plug, and the like can be removed through hydrogen.

When hydrogen is supplied to the engine combustion chamber, hydrogen is dissociated into hydrogen ions at a high temperature of 2,500 K as shown in the following reaction formula (3).

H _{2 -} > 2H * - (3)

The activated hydrogen ion (2H *) bonds with the carbon residue as shown in the following reaction formula (4).

C + H * - > C _X H _Y --- Reaction (4)

The carbon compound (C _X H _Y ) generated in the above reaction formula (4) is discharged to carbon dioxide and water through the combustion reaction as shown in the following reaction formula (5).

C _X H _Y + O ₂ ? CO ₂ + H ₂ O ????? (5)

As described above, some of the hydrogen supplied to the engine combustion chamber is combined with the carbon residue adsorbed to the engine combustion chamber or the like to be converted into a carbon compound (C _X H _Y ) to remove carbon residue, thereby reducing harmful exhaust gas and reducing fuel consumption . Referring to FIG. 5, it can be seen that the carbon residue on the suction valve or the carbon sludge is removed after hydrogenation.

In addition, the remaining part of the hydrogen supplied to the engine combustion chamber is burned together with the liquefied fuel such as gasoline, which has an advantage that the combustion efficiency can be improved by 10 to 20%.

6A is an exploded perspective view showing the water tank structure of the present invention, FIG. 6B is a longitudinal sectional view of FIG. 1, and FIG. 6C is a view showing a state in which the water tank of the present invention is kept horizontal when the water tank is disposed on an inclined surface .

6A to 6C, in the present embodiment, the buoyant body 115 is largely provided in the water tank, and the water tank 110 is kept horizontal.

The water tank 110 includes a body 111 for storing water and a lid 113 for sealing the opened upper portion of the body 111. The lid 113 is provided with a water suction hose 141, And a water discharge hose 145 is inserted and fixed.

When the water is pumped through the water suction hose 141, the lower end of the water suction hose 141 is completely immersed in the water, so that the pump 142 is smoothly operated. When the water in the water tub 110 is filled with more than half of the water, the water is sucked through the water suction hose smoothly despite the water swirling. However, as the amount of water filled in the water bath decreases, the lower end of the water suction hose 141 It is not completely immersed in water, and the probability of sucking in air is increased. In the case where the water suction hose 141 is exposed to the atmosphere rather than the water, the pump is driven in a state in which the water is not sucked, thereby causing a failure. Also, when the water is not supplied to the anode chamber, The negative electrode plate and the positive electrode plate may be damaged. If the water supply can not be continued in this way, a fire may occur due to the heating of the pump electrodes (anode and cathode plates).

To solve this problem, the buoyant body 115 and the horizontal holding means are used.

The buoyant body 115 is installed in the water tank 110 and has a shape corresponding to the cross section of the water tank 110. The buoyant body 115 floats on the water contained in the water tank 110, It plays a role. The water suction hose 141 and the hole 116 into which the water discharge hose 145 is inserted are formed in the buoyant body 115 and the buoyant body 115 is connected to the water suction hose 141, The hose 145 moves upward and downward while maintaining the horizontal movement without reversing the movement of the water.

It is preferable that a plurality of weight weights 117 are installed at a predetermined interval in the edge region of the buoyant body 115. The weight weights 117 may be a weight that does not completely immerse the buoyant body 115 And it plays a role of preventing the buoyant body from largely fluctuating in the movement of the water.

The horizontal holding means includes a plurality of gyro sensors 121 installed on one side of the water tub 110, a plurality of ball joints 123 provided on a lower surface of the water tub 110, And an elevating cylinder 125 installed in the gyro sensor 121. The gyro sensor 121 receives information on the tilted state of the water tub 110 and controls the lifting and lowering cylinders 125 individually And a control unit 127 for controlling the water tank 110 to maintain the horizontal state.

The control unit 127 may be connected to the gyro sensor 121 in a wired or wireless manner.

The ball joint 123 rotates so that the water tub 110 can be held horizontally when one of the lifting and lowering cylinders 125 is lifted or lowered.

The elevating cylinders 125 may be three or four at predetermined intervals along the bottom edge of the water tub 110.

When the horizontal holding means is provided together with the buoyant body 115, the buoyant body 115 can be positioned above the water in the water tank 110 while the water tank 110 is kept horizontal even when the vehicle runs on an inclined surface, The lower end portion of the water suction hose 141 can be stably sucked in a state in which the lower end portion of the water suction hose 141 is immersed in water, thereby preventing fire due to overheating of the pump and damage to the electrode.
