Abstract
Description
[Technical field]
[0001] This invention relates to a load driving device. [Background technology]
[0002] Conventionally, automobiles and the like have been designed to have only one tank, so when gasoline prices rise, there is a drawback in that the only option is to purchase and consume gasoline at that price.
[0003] [Patent Document 1] JP 2009-287484 A [Patent Document 2] JP 2010-121591 A Summary of the Invention [Problem to be solved by the invention]
[0004] Traditionally, automobiles and other vehicles have been designed to only have one tank, so when gasoline prices rise, it becomes possible to use cheaper diesel, reducing daily living expenses and increasing disposable income. [Means for solving the problem]
[0005] In order to solve the above problems, the present invention is characterized in that it comprises a first tank for holding gasoline, a second tank for holding diesel, a gasoline pump for sending gasoline from the first tank to a mixed oil tank, a diesel pump for sending the diesel from the second tank to the mixed oil tank, a two-liquid mixture ratio change device for changing the ratio of the mixed oil between the gasoline and the diesel, a carburetor to which the mixed oil is sent from the mixed oil tank, and a load that is driven by the mixed oil sprayed from the carburetor.
[0006] It is desirable to provide a pump motor that sends the mixed oil to the carburetor, and to have the pump motor automatically start and start refueling in response to a start signal indicating the lower limit of the oil level in the mixed oil tank, and to automatically stop and stop refueling in response to a stop signal indicating the upper limit of the oil level in the mixed oil tank. Effect of the Invention
[0007] According to claim 1, the invention has the effect of making it possible to use cheaper diesel when gasoline prices rise, thereby reducing the cost of daily life and increasing disposable income. The configuration as described in claim 2 has the effect of increasing the mixed oil ratio up to the upper limit, thereby enabling greater cost reduction. [Brief description of the drawings]
[0008] [Figure 1] FIG. 2 is a plan view of the load driver of the present invention; [Diagram 2] FIG. 2 is a plan view of the two-liquid mixture oil ratio changing device of the above. [Diagram 3] FIG. 2 is a side view of the two-liquid mixture oil ratio changing device.
[0009] As shown in Figures 1 to 4, the load drive device H comprises a first tank 1A for holding gasoline, a second tank 1B for holding diesel, a gasoline pump 11A for sending gasoline from the first tank 1A to a mixed oil tank 4, a diesel pump 11B for sending diesel from the second tank 1B to the mixed oil tank 4, a two-liquid mixture ratio change device 5 for changing the ratio of the mixed oil between gasoline and diesel, a carburetor 6 to which the mixed oil is sent from the mixed oil tank 4, and a load (internal combustion engine) 15 which is driven by the mixed oil sprayed from the carburetor 6.
[0010] The system is equipped with a first tank 1A for holding gasoline, a second tank 1B for holding diesel, a gasoline filler port and hose 2A, a diesel filler port and hose 2B, a gasoline delivery pipe 3A, a diesel delivery pipe 3B, a mixed oil tank 4 for a mixed oil of gasoline and diesel, a two-liquid mixed oil ratio change device 5 for changing the mixed oil ratio of gasoline and diesel, a carburetor 6 to which the mixed oil is delivered from the mixed oil tank, an internal combustion engine 15 serving as a load, a mixed oil pipe 7, a mixed oil signal wire 8, a remaining gasoline gauge 13 for indicating the remaining amount of gasoline, a gasoline remaining gauge signal wire 14, a diesel remaining gauge 9 for indicating the remaining amount of diesel, a diesel remaining gauge signal wire 10, a gasoline pump 11A, a diesel pump 11B, a gasoline pump signal wire 12A, and a diesel pump signal wire 12B.
[0011] The fuel pump consists of a motor, crank, piston, and cylinder. When the piston is pulled by the crank, a vacuum is created inside the cylinder, generating suction force. This suction force draws fuel from each of the fuel tanks, filling the cylinder. When the crank then pushes back the piston, pressure is applied to the fuel, which is pushed towards the mixed oil tank and supplied. This process is repeated for both gasoline and diesel, producing a mixed oil. The motor rotation speeds N1 and N2 are direct current and digitally controlled devices, making them easy to control, and the mixed oil ratio C can be easily and accurately controlled.
[0012] The oil blend ratio C of the fuel produced at this time can be explained mathematically as shown in the table below. TIFF0003249987000002.tif37151 Mixed oil ratio C=W1 / W2=N1 / N2 K1 / K2 The oil mixture ratio C is expressed by the product of the ratio N1 / N2 of the gasoline pump revolutions N1 and the diesel pump revolutions N2 and the cylinder capacity ratio K1 / K2. Since the cylinder capacity is K1=K2, K1 / K2=1, and so the oil mixture ratio C is controlled only by the motor revolutions ratio N1 / N2. This means that the oil mixture ratio C can be manually controlled by the two-liquid oil mixture ratio change device 5 in the driver's seat. The motor revolutions N1 and N2 are direct current and digitally controlled devices, so they are easy to control. Therefore, the oil mixture ratio C can be easily and accurately controlled.
[0013] The pump motor automatically starts and starts pumping when it receives a start signal indicating the lower limit of the oil level in the mixed oil tank, and automatically stops pumping when it receives a stop signal indicating the upper limit of the oil level in the mixed oil tank. The start / stop signal is sent by the ON / OFF switch.
[0014] The oil mixture with the mixture ratio set is sprayed into the internal combustion engine by the carburetor. The oil mixture ignites and explodes in the internal combustion engine, generating torque. The quality of the fuel is not important, since torque is generated as long as the gas is hot, regardless of the fuel. Of course, the structure of the internal combustion engine is not modified.
[0015] As shown in FIG. 2, the two-liquid mixture ratio change device 5 has the diesel ratio displayed on the outside and the gasoline ratio displayed on the inside so that the diesel mixture ratio can be changed by operating the lever 20 from 0 to 85% in 5% increments. When the gasoline ratio is set to 95% by operating the lever 20, the diesel ratio becomes 5%, and the signal is transmitted to the gasoline pump motor 19A and the diesel pump motor 19B as shown in FIG. 4, and the motors rotate according to the respective ratios to drive the piston 17 and send gasoline and diesel to the mixed oil tank 4. The lever of the two-liquid mixture ratio change device is plate-shaped, so that the mixed oil ratio can be achieved simply by turning it to the desired scale in the right direction, making it easy to operate even while driving. At the time of starting, the amount of gasoline can be increased to make starting easier, and at high speeds, if the engine is in good condition, the light vehicle can run with a high mixture ratio, so running costs can be minimized.
[0016] When producing 1000cc of mixed oil, the actual values are applied and the calculation is as shown in the table below. If the motor revolutions for gasoline and diesel are N1 and N2, and the cylinder capacity is K1 = K2 = 10cc, then the amount of gasoline oil W1 = N1K1 and the amount of diesel oil W2 = N2K2, so if you calculate the total amount of mixed oil W1 + W2 according to the motor revolutions (rpm), you will get the values in the table below.

[0017] Estimated reduction in consumption (yen / month) Gasoline 165 yen / L Diesel 131 yen / L TIFF0003249987000004.tif95152The greater the usage, the greater the reduction effect. [Industrial Applicability]
[0018] Traditionally, automobiles and other vehicles are designed to only have one tank, so if the blended oil ratio C can be increased and disposable income can be boosted when gasoline prices rise, people will have more free time to buy the things they normally want, which will have a ripple effect on other industries. The second fuel, which is an example of diesel fuel, may be alcohol, a synthetic fuel made from biomass, or a regenerated fuel, and the load driving device may be a generator, a combine harvester, or a tiller in addition to an automobile.
