Description

  The present invention relates to an HHO gas supply device for an internal combustion engine for supplying HHO gas to a fuel gas supply pipe of an internal combustion engine such as a prime mover that burns fuel such as gasoline, light oil or heavy oil.

  Conventionally, internal combustion engines that use fossil fuels such as gasoline, light oil, and heavy oil have not been sufficiently efficient in combustion. In this case, it is also known that if hydrogen is mixed in the fuel, the combustion efficiency is improved, and it is also proposed to use hydrogen by mixing HHO gas (oxyhydrogen gas, brown gas) into the fuel ( Patent Document 1). Many techniques for generating HHO gas by electrolysis have also been proposed (for example, Patent Document 2).

  In general, petroleum-based fuels are linked in a chain of carbon, and the number of hydrogen is less than the number of carbons. The oxygen in the air sent during combustion causes a combustion reaction with hydrogen, and the carbon is released without burning. Since it is released as incomplete combustion gas, it is considered that the combustion efficiency is not good. The HHO gas is a mixed gas of hydrogen and oxygen, and the composition ratio of the gas is generally a ratio of 2 hydrogen and 1 oxygen, and returns to water when left in the atmosphere. It is considered that the combustion efficiency can be improved by controlling the auxiliary combustion of the fossil fuel and HH0 gas currently used.

The HHO gas itself is a highly flammable gas, and the hydrogen gas contained in the gas has a high burning rate and is about 10 times faster than the carbon compound contained in fossil fuel. Thus, there is an effect of inducing the combustion of the carbon compound, and a continuous combustion reaction occurs. Therefore, hydrogen combustion and carbon combustion occur in the fossil fuel, and the state becomes closer to complete combustion. Therefore, if HHO gas is mixed in the fossil fuel, it becomes a state close to complete combustion, so that the combustion efficiency can be improved. In addition, unlike fossil fuels, HHO gas does not contain carbon compounds, so there is an advantage that CO ₂ is not generated after combustion.

2. Operation of HHO gas supply device 50

(1) The gas supply device 50 is turned on, the control device 40 is operated, the electromagnetic valve 18 in the water tank 15 is opened, and pure water is supplied from the discharge port 17 to the connection port 12 of the electrolyzer 1. The pure water is filled up to a predetermined depth in the electrolysis apparatus 1. In this case, the water surface position is set to 42 (FIG. 2), and the water surface position 42 is adjusted by the control device 40 so that the electrodes 5 and 5 are always immersed in water.

(2) Also, the lower chamber 27 of the gas stabilization device 20 is filled with pure water. In this case, for example, the discharge port 17 of the water tank 15 and the treatment port 29 of the gas stabilization device 20 are connected (pipe 39 shown by a chain line in FIG. 1), and pure water is supplied to the lower chamber 27 of the gas stabilization device 2. It can also be filled. In this case, the water surface 43 is set to be sufficiently higher than the receiving port 28 and below the processing port 29.
At this time, the pure water in the gas stabilizing device 20 does not have any trouble at normal temperature, but the preferred HHO gas temperature supplied to the fuel gas supply pipe 63 is 70 ° C. or less (maximum 120 ° C.), so that it is suitable. Adjust to.

(3) A prime mover (internal combustion engine) to which HHO gas is applied includes a fuel gas supply pipe 63 that supplies fuel gas from a fuel device 61 that generates fuel gas from a fuel tank to an engine (cylinder) 62. ing. A gas intake port 64 for HHO gas is formed in the middle of the fuel gas supply pipe 63, and the gas intake port 64 and the gas supply port 31 of the gas stabilizing device 20 are connected by a pipe 38 (FIG. 1). .

(4) Subsequently, the electrolysis apparatus 1 is operated to generate HHO gas according to a preset HHO gas supply amount (for example, about 800 to 1000 cc per minute). The generated HHO gas accumulates in the upper part of the electrolyzer 1 and is supplied from the discharge port 9 through the pipe 36 to the receiving port 28 of the gas stabilizing device 20. The HHO gas that has entered the lower chamber 27 is cooled by pure water in the lower chamber 27, and is accumulated in the upper portion of the lower chamber 27. The valve body 25 is pushed up by the pressure of the accumulated HHO gas (shown by a solid line in FIG. 3). It accumulates in the upper chamber 26 from the communication hole 24 and is gradually supplied from the gas supply port 31 through the pipe 38 to the fuel gas supply pipe 63.
Since the amount, temperature, etc. of the HHO gas generated by the electrolysis apparatus 1 are controlled by the control device 40 so as to have preset values and are discharged from the discharge port 9, the gas supply port of the gas stabilization device 20 The HHO gas supplied from 31 is also provided at a constant amount and temperature. Therefore, the prime mover (internal combustion engine) to which hydrogen is supplied by the HHO gas can operate efficiently by using the fuel gas without waste. Specific effects will be described in the next section.

(5) If an abnormality (explosion or the like) occurs instantaneously in the engine 62 or the fuel supply device 61 during operation, the fuel gas supply pipe 63 to the HHO gas intake 54, the pipe 38, the gas supply port In some cases, “pressurized gas mixed with fuel” is allowed to flow instantaneously through the gas flow 31. In this case, the pressure is applied to the upper chamber 26 of the gas stabilizing device 20 in the direction of the chain line arrow 54, but the valve body 25 is in the chain line position and closes the communication hole 24. Since the “pressurized gas” does not enter, the electrolysis apparatus 1 is not adversely affected.
The “pressurized gas mixed with fuel or the like” that has entered the upper chamber 26 is supplied with the HHO gas and then supplied with the HHO gas through the gas supply port 31, the pipe 38, and the HHO gas intake 64. Since it returns to the pipe | tube 63, the operation | movement of the subsequent HHO gas supply apparatus 50 can be continued without trouble.

(6) If the HHO gas is abnormally generated in the electrolysis apparatus 1, the pressure below the lid 4 of the electrolysis apparatus 1 becomes high, and the pressure sensor (not shown) exceeds the set pressure. Upon sensing, the control device 40 opens the solenoid valve 19 of the connection port 12. Accordingly, the HHO gas enters the lower chamber 27 through the connection port 12, the pipe 37, and the processing port 29. The HHO gas (slightly high temperature) that has entered the lower chamber 27 is sent to the upper chamber 26 together with the HHO gas that has passed through normal water. Therefore, the generated HHO gas is not wasted without placing a burden on the electrolyzer 1.
In this case, the connection port 12 of the electrolyzer 1 and the treatment port 29 of the gas stabilization device 20 are connected, but an on-off valve may be provided to open the second connection port 12 to the atmosphere.

3. Experiment of effect of HHO gas supply device 50

(1) For example, the present invention is applied to a gill fishing boat equipped with a diesel engine for a small fishing boat of 5 ton class (displacement of about 7000 cc). The HHO gas supply device 50 generates 800 to 1000 cc of HHO gas per minute and supplies the HHO gas to the prime mover 60.
In this case, on the same fishing boat, the total consumption of fuel gas oil when fishing for 3 days (3 times) without supply of HHO gas, when the HHO gas is supplied and fishing for 3 days (3 times) The total consumption of fuel gas oil is as shown in Table 1 below.
In this navigation experiment, when the HHO gas was supplied, a fuel reduction of about 23% was achieved compared to the case where it was not supplied. In this case, the engine was used at a relatively high speed specification of 2000 to 2500 engine revolutions in a 40 to 200 mile sailing.

(2) When the same size gas supply device 50 is used and 1000 to 1200 cc of HHO gas is supplied to the prime mover 60 in one minute and applied to a 9.7-ton squid fishing fishing boat, the HHO The total fuel gas oil when fishing for 4 days (3 times) with and without gas is the result shown in the table below.
In this navigation experiment, when the HHO gas was supplied, the fuel gas oil was reduced by about 29% compared to when the HHO gas was not supplied.
