Description

  The present invention relates to a fuel efficiency improvement system for various vehicles equipped with a power generation device, particularly various internal combustion engines equipped with a power generation device such as a motorcycle or automobile.

  On-demand small oxygen and hydrogen gas generators that use oxygen and hydrogen gas generated from water (hereinafter referred to as HHO gas) as combustion accelerators are attracting attention as a means for improving combustion in internal combustion engines. A method using a gas generator) is known. In addition, recently, related sites are often found on the overseas Internet and YOU-TUBE.

  However, in the present situation, even if the HHO gas generator is mounted on a vehicle, the expected effect cannot be obtained in a large displacement large vehicle, many other vehicles except for ships, etc. However, implementation is not progressing because it is large and expensive.

  In particular, if the gas generator is made smaller and lighter or the material of the component parts is made of an inexpensive material, the amount of gas generated will be insufficient, and there will be no effect as a combustion accelerator, resulting in improved fuel efficiency. It was n’t connected. Also, for motorcycles and small and medium-sized cars, even if the amount of gas generated is sufficient, in a driving situation where the load applied to the alternator is large, the load to generate electricity becomes the resistance of the engine, leading to fuel efficiency reduction. On the contrary, it caused fuel consumption deterioration.

  Furthermore, the conventional method does not consider a technique for matching the injection amount of the HHO gas with the driving mode of the vehicle, and depending on the driving situation, a phenomenon of an increase in carbon monoxide in the exhaust gas is seen, and as a combustion accelerator Contrary incomplete combustion has occurred.

  The present invention has been made in view of the above, and incorporates an HHO gas generator that is economical and compact in size into an internal combustion engine of various vehicles, and at the same time controls the gas generator as appropriate. The fuel consumption is definitely reduced by injecting an appropriate amount of fuel.

  The present invention is a vehicle fuel efficiency improvement measure that uses HHO gas generated by electrolysis of water as a combustion accelerator using on-vehicle power sources of various vehicles. An inexpensive and compact HHO gas generator that employs an electrode plate that has been subjected to pure nickel spraying, means for controlling the injection amount of the HHO gas according to the vehicle operating status and the load status of the alternator, The present invention proposes a vehicle fuel efficiency improvement system comprising a combination with a complementing means for complementing a control means, and simultaneously configured to inject the HHO gas into an intake pipe between an air cleaner and a throttle valve. .

  Thus, according to the present invention, it has been confirmed that the improvement in fuel efficiency is surely improved by 5% to 20% in various types of vehicles including vehicles of 3000 cc or less.

  For Japan, where almost 100% of fossil fuel is imported and the price of fossil fuel is expected to rise in the future, the present invention has an economic rationality and its utility value is extremely large.

It is a schematic block diagram which shows the layout of this invention. It is a longitudinal cross-sectional view which shows the principal part of the gas generator of this invention.

  FIG. 1 is an embodiment showing an overall schematic configuration of the present invention, and FIG. 2 is a longitudinal sectional view of an essential part of a gas generator used in FIG. In the figure, 1 is an engine, 2 is an air cleaner, 3 is an intake manifold, 4 is an alternator, 5 is a throttle valve, and 6 is an intake pipe. The discharge port A1 of the HHO gas generator A communicates with the intake pipe 6 between the throttle valve 5 and the air cleaner 2 via the water vapor removal device B and the backfire prevention device C. The pressure sensor D that detects the pressure of the intake manifold 3 inputs the output signal to the engine control unit E. Further, an output signal from a sensor F that detects the load status of the alternator 4 is also input to the engine control unit E. At the same time, an output signal from a vehicle speed sensor H that senses the running state is also input. The HHO gas generator A formed as described later adjusts the current by the current control unit A3 based on the control signal of the engine control unit E, generates a desired amount of HHO gas, and supplies it to the intake pipe 6 It has become. The G indoor control switch is an on / off type control switch that operates in conjunction with the engine start switch 7 installed in the vicinity of the driver's seat, and can be arbitrarily turned off and the status of the HHO gas generator A, Meter G1 etc. which can grasp system information are also provided. The tank A2 is a sub-tank for the electrolyte, and has a structure that can be replenished with water because the water decreases as the HHO gas is generated for a long time.

In the above structure, the HHO gas generator A was set as follows based on various experimental results of the inventors of the present application.
(1) As the electrode used, pure stainless steel as the base material is used for the anode side (SUS316L is preferable) and stainless steel is used for the cathode side in consideration of durability, economy and electrolysis efficiency while excluding expensive rare metals such as platinum. An electrode plate sprayed with nickel was used.
(2) As shown in FIG. 2, a specific arrangement structure of the electrode plate is as follows. An anode stainless steel plate A5 is arranged at one end of a resin casing A7 for housing the electrode plate and the like, and a nickel plate A6 is arranged at the other end of the cathode. In addition, in each intermediate electrode A4, an intermediate electrode type in which pure nickel was sprayed on one surface of a stainless steel plate was adopted to reduce the size and weight of the casing A7.
▲ 3 ▼ a unitary construction of the respective electrode plates and 200cm ² ~250cm ² mm, the total area at the same time very good lightweight small volume of Increasing the efficiency of generation of HHO gas by to 6000cm ² ~6500cm ² thereof It was supposed to be.
(4) Regarding the electrolytic solution and the electrolytic solution concentration, 5% by weight sodium hydroxide or potassium hydroxide solution with the most stable electrolysis efficiency was adopted, and it was assumed that it was excellent in availability.
(5) The electrolysis voltage is structured such that a low voltage electrode layer operating at around 1.7 V per cell is connected in series with 7 cells or 6 cells, and electrolysis can be performed with a total of slightly over 12 V. Since it operates at a low voltage, it suppresses the temperature rise of the aqueous electrolyte solution and prevents the generation efficiency of the HHO gas and the dissolution of metal at the anode. It was not necessary. When the in-vehicle power supply is 24V, it is possible to ensure the stability of the generation amount by connecting the HHO gas generator A in series.
(6) The electrolysis current is 10A to 30A having high electrolysis efficiency, and the necessary amount of HHO gas generated can be secured at all times.
(7) The gap between the electrodes is 2 mm depending on the relationship between the electrolyte and electrolyte concentration, the relationship of bubbles adhering to the electrode plate, the shape of the gas discharge holes discharged from the cell, etc. Before and after. However, in the electrode arrangement other than the intermediate electrode type, about 1 mm is highly efficient.
(8) The HHO gas discharge hole and the electrolyte injection hole of each cell have a structure in which adjacent cells do not cause leakage due to the electrolyte, and the opening area of the electrolyte injection hole is the opening area of each HHO gas discharge hole. Of 1/2 or less.

  As a result of using a combination of the above-mentioned setting conditions (1) to (8) as appropriate, it has been found that it is possible to generate sufficiently satisfactory HHO gas for internal combustion engines of many vehicles.

  Next, HHO gas injection and injection amount control means will be described. The appropriate range of the HHO gas injection amount is, for example, too large a difference between the rotation speed at the maximum output and the rotation speed during normal use. The number is different. Therefore, the conventional method for determining the injection amount of the HHO gas only by the difference in the displacement and the output horsepower is not preferable.

  The injection amount of HHO gas in the present invention is not a conventional method that depends only on the engine displacement and output horsepower, but matches the engine displacement and the operation mode such as rapid acceleration, deceleration, steady running, idling, etc. As a result of determining the amount through the engine control unit E and injecting this amount, the combustion efficiency is high and the fuel consumption can be greatly reduced. In addition, when the alternator 4 reaches a high load state exceeding a predetermined value for some reason by the load detection sensor F of the alternator 4, the current control unit A3 is temporarily interrupted via the engine control unit E, Since it includes a means for controlling the injection amount of the HHO gas in order to reduce the engine load by intermittent operation, the improvement of fuel consumption is surely executed. The following table shows the control status of the HHO gas injection amount in the present invention.

  Next, supplementary means for controlling the gas generator A according to the present invention will be described based on each operation mode. The indoor control switch G and each sensor forming the complement means control the operation of the gas generator A “ON” and “OFF” as shown in the following table.

  The control switch G provided in the vicinity of the driver's seat is interlocked with the engine start switch 7 and has a structure that does not operate by the HHO gas generator A alone, thereby ensuring safety that does not generate unnecessary gas. The vehicle speed sensor H recognizes the stoppage of travel and prevents the HHO gas generator A from being operated at the start, and also during idling and warm-up operation. The pressure sensor D recognizes the traveling state, operates the HHO gas generator A in a traveling state at a low load, and injects HHO gas into the intake pipe 6. In other traveling states, the HHO gas generator A is stopped and HHO gas is not injected.

  The fuel efficiency improvement system of the present invention is useful for a wide variety of vehicles and ships that run on internal combustion engines. Moreover, it is useful regardless of fuel differences such as gasoline and diesel engines. In particular, it is effective for vehicles that use long distances related to transportation that frequently uses highways.
