Description

  The present invention relates to a fuel efficiency improvement device that improves the fuel efficiency of an automobile.

In recent years, the number of automobiles worldwide has increased dramatically due to the activation of motorization. Along with this, the amount of exhaust gas discharged from these automobiles is also increasing. A large amount of exhaust gas pollutes the atmosphere and destroys the environment. Further, carbon dioxide gas contained in a large amount in exhaust gas is called greenhouse gas and is a major cause of global warming.
On the other hand, the recent surge in gasoline and diesel oil has tightened household budgets and made life difficult, and led to rising prices due to rising trucking costs. In addition, there is a global situation that an increase in consumption of gasoline and light oil in Japan leads to a surge in crude oil in oil-producing countries.
Therefore, in order to suppress the consumption of automobile fuel that leads to air pollution and global warming as described above, for example, it is composed of a copper metal member, aluminum and iron, and the fuel is activated in the fuel tank to improve fuel efficiency. Fuel efficiency improvement auxiliary material (the following patent document 1) to be improved, and a fuel efficiency improvement device for improving the fuel efficiency by attaching a mixture mainly composed of crystal, metal oxide and noble metal to the fuel system (the following patent document 2) ), And a torque converter (which will be described below) to reduce power transmission loss and improve fuel efficiency by inclining the blade angle of the pump impeller to a predetermined angle and inclining the blade angle of the turbine impeller to a predetermined angle. Patent Document 3) has been developed.

JP-A-6-9971 JP-A-8-35454 JP-A-11-173401

  However, since the techniques described in Patent Documents 1, 2, and 3 described above all need to be installed in individual automobiles, the cost is high when viewed from the entire owned automobiles. In particular, the torque converter described in Patent Document 3 is not only a research and development cost, but also a material cost and a processing cost. Therefore, the torque converter has to be a high-priced part and is difficult to spread to the general public. Thus, if it cannot spread widely in general society, it cannot bring about the effects of preventing air pollution and suppressing global warming on a global scale. Incidentally, automatic transmission fluid (hereinafter abbreviated as ATF) used in torque converters plays a very important role under favorable conditions that do not come into contact with combustion gas. Because it is used, it is rarely replaced. On the other hand, since the fuel efficiency improvement auxiliary materials and the fuel efficiency improvement devices described in Patent Documents 1 and 2 use magnetic force and electromagnetic waves, a significant reduction in fuel efficiency cannot be expected.

  The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide a fuel efficiency improvement device that can easily and dramatically improve the fuel efficiency of an automobile with a simple and inexpensive configuration.

  In order to achieve the above object, a fuel efficiency improvement device for an automobile according to claim 1 of the present invention includes an oil inlet / outlet tube whose tube tip is inserted into an ATF inlet / outlet of an automatic transmission of the automobile, and a tube end of the oil inlet / outlet tube. Sealed waste oil container to be connected, pump suction side connected to the waste oil container, suction pump for sucking the waste oil container and the oil inlet / outlet tube, the tube tip side and the tube provided in the middle of the oil inlet / outlet tube A flow path switching unit that switches between a flow path that connects the end side, a flow path that connects the tube tip side and the outside, and an injection unit for injecting ATF new oil provided in a path to the outside in the flow path switching unit It is made.

  According to a second aspect of the present invention, there is provided a fuel efficiency improving device for an automobile, an oil inlet / outlet tube whose tube tip is inserted into an ATF inlet / outlet of an automatic transmission of the automobile, a pump for sending ATF, and a tube end of the oil inlet / outlet tube. A pump suction passage that connects the suction port of the pump and the pump, a pump discharge passage that connects the tube end of the oil inlet / outlet tube and the discharge port of the pump, and a waste oil container that is branched and connected to the pump discharge passage via a waste oil recovery passage A new oil container branched and connected to the pump suction path via a new oil supply path, a flow path from the oil inlet / outlet tube through the pump suction path, pump, pump discharge path, and waste oil recovery path to the waste oil container, A flow path switching unit that switches a flow path from the new oil container to the oil inlet / outlet tube through the new oil supply path, the pump suction path, the pump, and the pump discharge path is provided.

  In the configuration of each of the above-described claims, there is provided measuring means for measuring the waste oil of ATF flowing in from the oil inlet / outlet tube and stored in the waste oil container.

  Since the fuel efficiency improvement device for an automobile according to claim 1 of the present invention is mainly composed of an oil inlet / outlet tube, a waste oil container, a suction pump, a flow path switching unit, and an injection unit for injecting ATF new oil, it has a simple configuration. Provided at low cost. And although it is such a simple and cheap structure, the waste oil of ATF can be simply extracted from an automatic transmission, and it can collect | recover in a waste oil container, and can replace the new oil of ATF with an automatic transmission from an injection part. Thereby, the transmission loss of the driving force from the engine to the tire is remarkably reduced. As a result, the fuel efficiency of the automobile is greatly improved. Moreover, since the amount of exhaust gas is reduced, it contributes to the prevention of air pollution, and at the same time, the amount of generated carbon dioxide gas is reduced, thereby contributing to the suppression of global warming.

  The fuel efficiency improving apparatus for an automobile according to claim 2 of the present invention can take out ATF waste oil from the automatic transmission and supply new oil of ATF to the automatic transmission by driving a pump. Therefore, ATF replacement in the automatic transmission can be performed quickly without much effort. Of course, fuel consumption can also be reduced, contributing to air pollution prevention and global warming suppression.

  In each of the above-described configurations, the measuring device that measures the ATF waste oil can know the amount of waste oil taken out from the automatic transmission and stored in the waste oil container by the measuring device. By using the amount of waste oil as a guide, an appropriate amount of new oil can be supplied to the automatic transmission, so that new oil is not spilled wastefully.

The best embodiment of the present invention will be described with reference to the drawings. The embodiment described below is merely an example embodying the present invention, and does not limit the technical scope of the present invention. FIG. 1 is a configuration diagram including a partial cross section of a fuel efficiency improvement apparatus according to an embodiment of the present invention, and FIG. 2 is an external view of an automatic transmission for an automobile to which the fuel efficiency improvement apparatus is applied.
In each figure, the automobile fuel efficiency improving apparatus 1 according to this embodiment includes a waste oil container 3 for storing waste oil Lo of ATF (for example, using a product “ATF-HYPER-S” manufactured by Wako Chemical Co., Ltd.). The waste oil container 3 includes a bottomed cylindrical container body 25 having an upper surface opening and a lid body 26 that covers the upper surface opening of the container body 25. A flange 27 provided on the outer peripheral edge of the upper end of the container body 25 and a flange 28 provided on the outer peripheral edge of the lower end of the lid body 26 are fixed by a bolt 29 and a nut 30 so as to be freely opened and closed. . An O-ring 34 is interposed between the container body 25 and the lid body 26 to seal the waste oil container 3. The metal pipe 13 is connected to the lid body 26 of the waste oil container 3 described above, and the end of the metal pipe 13 passes through the lid body 26 and is located in the waste oil container 3. The metal tube 13 is inserted into a cylindrical bolt 31 fixed on the upper surface of the lid body 26 and is hermetically fixed by a cap nut 32 and an O-ring 33. The lid body 26 is fixedly provided with a suction pipe 5 having one end passing through the lid body 26 and the other end connected to the pump suction side 4A of the suction pump 4. A pressure gauge 35 that detects the degree of decompression in the waste oil container 3 is installed on the lid 26.

  The tip of the metal pipe 13 is connected to the passage 19 of the valve casing 16 of the three-way switching valve 9. In the valve casing 16 of the three-way switching valve 9, a passage 7 for connecting to an external new oil container 24 and a passage 18 for connecting to the flexible tube 12 are formed in addition to the above-described passage 19. The flexible tube 12 is connected to the flexible tube 11 via the joint portion 14. That is, the oil in / out tube 2 is configured by the flexible tube 11, the joint portion 14, the flexible tube 12, and the metal tube 13. In this case, the tip of the flexible tube 11 becomes the tube tip 2A of the oil inlet / outlet tube 2, and the end of the metal tube 13 becomes the tube end 2B of the oil inlet / outlet tube 2. The lower end of the connecting pipe 23 is connected to the passage 7 of the valve casing 16, and the connection port 23 </ b> A at the upper end of the connecting pipe 23 is connected to the nozzle at the bottom of the new oil container 24. That is, the connecting pipe 23 becomes the injection portion 8 for injecting ATF new oil connected to the passage 7 for connection to the external new oil container 24. A cylindrical valve body 17 is rotatably mounted on the inner peripheral valve seat of the valve casing 16. Three passages 20, 21, 22 are formed in the valve body 17 so as to have a T-shaped cross section. The valve body 17 is connected to a drive shaft of a motor 37, and is rotated by driving of the motor 37 so as to communicate and block each passage.

  The waste oil container 3 contains a measuring cup 36 (an example of measuring means). The measuring cup 36 is formed in a bottomed cylindrical shape using, for example, an oil-resistant and transparent synthetic resin as a material, and a scale indicating the amount of oil is formed on the peripheral wall thereof. The measuring cup 36 is installed on the bottom surface of the waste oil container 3 at a position below the tube end 2B of the oil inlet / outlet tube 2. As a result, the ATF waste oil Lo sucked out from the automatic transmission 45 and introduced from the oil inlet / outlet tube 2 is stored. The control device 38 is composed of, for example, a microcomputer including a CPU, a memory, a data bus, etc., receives a pressure signal from the pressure gauge 35, and transmits a drive signal to the suction pump 4 and the motor 37.

  FIG. 2 shows a general automatic transmission 45 of an automobile. The automatic transmission 45 is composed of a torque converter unit 46 incorporating a stator and a turbine, and an auxiliary transmission unit 47 incorporating a planetary gear. An oil pan 50 that stores ATF is provided at the bottom of the automatic transmission 45. The AFT in the oil pan 50 is pumped up by an oil pump (not shown) inside the apparatus, flows through the torque converter unit 46 and the auxiliary transmission unit 47, and returns to the oil pan 50. The amount of oil in the automatic transmission 45 can be confirmed by an oil amount gauge 49 that is inserted into and removed from an inlet / outlet 48A of an oil amount confirmation pipe 48 protruding upward from the lower portion of the automatic transmission 45. In the vicinity of the oil pan 50, oil is connected to an oil inlet 51 connected to a pipe for sending ATF from an oil pump to an oil cooler (not shown), and a pipe for returning the ATF from the oil cooler to the oil pan 50. An outlet 52 is provided.

  By the way, ATF is generally composed of various base materials such as mineral oil base oil, detergent dispersant, friction modifier, antioxidant, antifoaming agent, metal deactivator and the like. This ATF causes a decrease in oil viscosity due to decomposition / deterioration reaction of the base material due to operation under high temperature / high oxidation conditions, severe operation without warm-up operation, and the like. Thus, when the oil viscosity of ATF decreases, transmission of engine driving force to the tire decreases. As a result, it is known that automobile fuels such as gasoline and light oil are consumed unnecessarily.

  Therefore, the operation of the fuel consumption improvement apparatus 1 configured as described above will be described next. First, the operator places the measuring cup 36 on the bottom surface of the container body 25 of the waste oil container 3, and the lid is closed with the lid body 26 and hermetically fixed with the bolt 29 and the nut 30. Next, the operating portion of the control device 38 is operated to drive the motor 37 to rotate the valve element 17 of the three-way switching valve 9 so that the passage 18 and the passage 20 and the passage 22 and the passage 19 are communicated with each other. It switches to the flow path which connects 2A and the tube end 2B. Then, the tube tip 2A of the oil inlet / outlet tube 2 is inserted from the inlet / outlet port 48A (an example of the ATF inlet / outlet port) of the oil amount confirmation pipe 48 of the automobile to reach the bottom of the oil pan 50.

  Subsequently, when the controller 38 is operated to drive the suction pump 4, the suction pump 4 sucks out the air in the waste oil container 3 and the oil inlet / outlet tube 2 and puts the inside of each in a reduced pressure state. As a result, the ATF waste oil Lo in the oil pan 50 is sucked out and stored in the measuring cup 36 from the tube end 2B of the oil inlet / outlet tube 2. Among them, when the AFT in the oil pan 50 almost disappears, air is sucked in, so that the pressure in the waste oil container 3 rises. When this pressure reaches a predetermined pressure close to the atmospheric pressure, the pressure gauge 35 outputs a detection signal to the control device 38. Then, the control device 38 stops driving the suction pump 4 and drives the motor 37 to switch the flow path of the valve body 17 to the flow path connecting the tube tip 2A side of the oil inlet / outlet tube 2 and the new oil container 24. That is, the three-way switching valve 9 of the flow path switching unit 6 switches between a flow path connecting the tube tip 2A side and the tube end 2B side, and a flow path connecting the tube tip 2A side and the external new oil container 24.

  Therefore, the nut 30 is loosened, the lid body 26 is opened, and the amount of the ATF waste oil Lo in the measuring cup 36 is visually confirmed. By the way, in the case of a light car, it is around 3 liters. Then, an amount of ATF new oil Ln slightly smaller than the amount of ATF waste oil Lo collected in the measuring cup 36 is poured into the new oil container 24. Then, the ATF fresh oil Ln in the new oil container 24 flows into the oil pan 50 from the oil inlet / outlet tube 2 through the passage 7, the passage 20, the passage 21, and the passage 18 of the three-way switching valve 9 by its own weight. Then, while changing the shift position of the AT shift lever, the handler repeatedly starts and stops the engine, checks the amount of oil using an oil amount gauge, and adds the ATF new oil Ln to the new oil container 24. Thus, when the oil amount by the oil amount check reaches the specified level, the ATF new oil replacement is completed.

As described above, the fuel efficiency improving device 1 has a simple and inexpensive configuration mainly including the oil inlet / outlet tube 2, the waste oil container 3, the measuring cup 36, the suction pump 4, the three-way switching valve 9, and the control device 38. Conveniently, almost all of the ATF waste oil Lo can be extracted from the automatic transmission 45 and collected in the waste oil container 3, and the ATF new oil Ln can be replaced with the automatic transmission 45 from the new oil container 24. Thereby, the transmission loss of the driving force from the engine to the tire is remarkably reduced. As a result, the fuel consumption is reduced by 30 to 40% for the same travel distance, and the fuel cost is reduced. In addition, since the amount of exhaust gas is reduced, it contributes to the prevention of air pollution, and at the same time, the amount of generated carbon dioxide gas is reduced, thereby contributing to the suppression of global warming. In addition, the reduction in consumption of gasoline and light oil in Japan by the fuel efficiency improvement device 1 leads to the suppression of the rise in crude oil prices in oil-producing countries, and consequently the increase in domestic prices. As a result, the Japanese people will become richer in spirit and will, for example, drive on holidays frequently.
Although the automobile manufacturer recommends replacing the ATF at a traveling distance of 50,000 km, if it exceeds 20,000 km, the power transmission loss of the automatic transmission 45 increases due to the deterioration of the ATF. Therefore, it is desirable to replace the ATF before the traveling distance of 20,000 km.

  On the other hand, the ATF of the automatic transmission 45 can be taken in and out using the oil inlet 51 or the oil outlet 52 as the ATF inlet / outlet of the present invention instead of the inlet / outlet 48A of the oil amount confirmation pipe 48. It is also possible to omit the control device 38, the motor 37, and the pressure gauge 35 and replace the ATF by hand. In this case, an inexpensive fuel economy improving device with a simpler configuration is provided. .

  And in said embodiment, although the flow-path switching part 6 using the one three-way switching valve 9 was illustrated, the three-way switching valve 9 is abbreviate | omitted as a piping branch part, and between the new oil containers 24 from this piping branch part Of the connecting pipe 23 and the metal pipe 13 between the pipe branching portion and the waste oil container 3 are provided with on-off valves 39 and 40 (indicated by a two-dot chain line in the figure), respectively, so that the flow path switching portion referred to in the present invention is provided. It is also possible. That is, by combining the open / closed states of these on-off valves 39 and 40, a flow path connecting the tube tip 2A side and the tube end 2B side and a flow path connecting the tube tip 2A side and the external new oil container 24 are selectively selected. You can switch to

In the above description, the flow path is switched using one three-way switching valve 9 and the ATF fresh oil Ln is supplied by its own weight. However, the present invention is not limited to such a configuration. . For example, as shown in FIG. 3, a fuel efficiency improvement device 1a that switches the flow path using three three-way switching valves and supplies ATF new oil Ln by pump power is also included in the present invention.
The fuel efficiency improving device 1a includes an oil inlet / outlet tube 2a in which the flexible tube 11 and the flexible tube 12 are connected via a joint portion 14, a pump 55 for sending out ATF, a tube end 2B of the oil inlet / outlet tube 2a, and a pump. A pump suction path 56 that connects the 55 suction port 55 A, a pump discharge path 57 that connects the tube end 2 B of the oil inlet / outlet tube 2 a and the discharge port 55 B of the pump 55, and a waste oil recovery path in the middle of the pump discharge path 57. The waste oil container 3 branchedly connected via 58 and the new oil container 24 branchedly connected via a new oil supply path 59 in the middle of the pump suction path 56 are provided.

  A three-way switching valve 61 is provided at the junction of the pump suction passage 56, the pump discharge passage 57, and the tube end 2B of the oil inlet / outlet tube 2a. In the valve casing 64 of the three-way switching valve 61, a passage 66 to which the tube end 2B of the oil inlet / outlet tube 2a is connected, a passage 67 to which the end of the pump suction passage 56 is connected, and a passage 68 to which the tip of the pump discharge passage 57 is connected. And are formed. Two passages 69 and 70 are formed in the valve body 65 that is rotatably mounted on the inner peripheral valve seat of the valve casing 64 so as to have a substantially L-shaped cross section. A three-way switching valve 62 is provided at a branch portion of the pump suction passage 56 with the new oil supply passage 59. In the valve casing 71 of the three-way switching valve 62, a passage 73 connected to the pump suction passage 56 upstream of the branch portion, a passage 74 connected to the pump suction passage 56 downstream of the branch portion, and a new oil supply A passage 75 to which the end of the passage 59 is connected is formed. Two passages 76 and 77 are formed in the valve body 72 rotatably attached to the inner peripheral valve seat of the valve casing 71 so as to have a substantially L-shaped cross section. A three-way switching valve 63 is provided at a branch portion of the pump discharge passage 57 with the waste oil recovery passage 58. The valve casing 78 of the three-way switching valve 63 has a passage 80 connected to the pump discharge passage 57 upstream from the branch portion, a passage 81 connected to the pump discharge passage 57 downstream from the branch portion, and a waste oil recovery passage. A passage 82 is formed to which the ends of 58 are connected. Two passages 83 and 84 are formed in the valve body 79 that is rotatably mounted on the inner peripheral valve seat of the valve casing 78 so as to have a substantially L-shaped cross section. These three three-way switching valves 61, 62, 63 constitute a flow path switching unit 60.

According to the fuel efficiency improving apparatus 1a having the above-described configuration, the passage 66 and the passage 69 and the passage 70 and the passage 67 of the three-way switching valve 61 communicate with each other and the passage 73 and the passage of the three-way switching valve 62 communicate with each other when the ATF waste oil Lo is extracted and collected. The rotational positions of the valve bodies 65, 72, and 79 are set so that 76, the passage 77, and the passage 74 communicate with each other, and the passage 80, the passage 83, and the passage 84, and the passage 82 of the three-way switching valve 63 communicate with each other. When the pump 55 is driven in this state, the ATF waste oil Lo of the automatic transmission is sucked out from the tube tip 2A of the oil inlet / outlet tube 2a and passes through the pump suction path 56, the pump 55, the pump discharge path 57, and the waste oil recovery path 58. It is collected in the waste oil container 3.
On the other hand, when supplying the ATF new oil Ln to the automatic transmission, the valve bodies 65, 72, 79 of the three-way switching valves 61, 62, 63 are rotated manually or electrically, and the pump suction path from the new oil supply path 59 is obtained. 56, the respective passages are switched from the upstream side to the downstream side of the pump discharge passage 57 and from the pump discharge passage 57 on the downstream side to the oil inlet / outlet tube 2a. That is, the flow path from the oil inlet / outlet tube 2a to the waste oil container 3 through the pump suction path 56, the pump 55, the pump discharge path 57, and the waste oil recovery path 58, the new oil supply path 59, the pump suction path from the new oil container 24 The three-way switching valves 61, 62, and 63 that switch the flow path to the oil inlet / outlet tube 2a via the pump 56, the pump 55, and the pump discharge path 57 constitute a flow path switching unit 60. When the pump 55 is driven in this state, the ATF new oil Ln in the new oil container 24 passes through the new oil supply path 59, the pump suction path 56, the pump discharge path 57, and the oil inlet / outlet tube 2a, and then the oil pan of the automatic transmission 45. 50.
As described above, the fuel efficiency improvement device 1 a can take out the ATF waste oil Lo from the automatic transmission 45 and supply the ATF fresh oil Ln to the automatic transmission 45 by driving the pump 55. Accordingly, the ATF can be replaced quickly in the automatic transmission 45 without much effort.

In the above-described embodiment, the flow path switching unit 60 using the three three-way switching valves 61, 62, 63 is illustrated, but the present invention is not limited thereto. These three-way switching valves 61, 62, 63 are abolished and those parts are used as piping branch parts, and on-off valves are respectively provided in the pump suction passage 56, the pump discharge passage 57, the waste oil recovery passage 58, and the new oil supply passage 59. By providing 85, 86, 87, 88 (indicated by a two-dot chain line in the figure), it is possible to provide a flow path switching unit as referred to in the present invention.
In the above, an example is shown in which the present invention is applied to an automatic transmission comprising a torque converter section and a sub-transmission section. However, a belt-type CVT type automatic transmission that performs a continuously variable transmission using a metal belt and a pulley is of the same type. Therefore, the fuel efficiency improving apparatus of the present invention can be applied to a belt type CVT type automatic transmission.
The measuring cup housed in the waste oil container is used as the measuring means. However, a waste oil container in which the container itself is made of a transparent material and the peripheral wall is provided with an oil measuring scale can also be used as the measuring means. Alternatively, an oil level detection sensor for detecting the oil level of the ATF waste oil can be provided in the waste oil container and used as a measuring means.

It is an external view of the automatic transmission of a motor vehicle to which the fuel efficiency improving device is applied. It is a block diagram containing the partial cross section of the fuel consumption improvement apparatus which concerns on another embodiment of this invention.
