2. Description of the Related Art In practical use to date, glow engines and similar diesel engines which are widely commercialized as model power engines are remarkable examples. General industrial production is applied to small gasoline engines,
The use of a mixed fuel for two-stroke engines and the one-through mode by the separate supply of lubricating oil are known, but the field of diffusion is limited and the use of petroleum is at present. In addition, although research and development has been found on the driving of internal combustion engines with vegetable oil fuel, mineral oil is a common example in selecting lubricating oil.

[0003]

[Problems to be Solved by the Invention] Avoidance of depletion of petroleum energy arriving in the near future, response to prolonged life, improvement of the global environment by mitigating exhaust gas pollution by power fuel, renewable energy from unilateral energy resource consumption structure It aims to solve the problem of power and energy in developing countries, such as in the development and industrialization of cycle resources, and in countries with poor oil resources and in these non-oil reserves.

[Means for Solving the Problems] A diesel engine used in a wide range due to its excellent output characteristics regardless of the advanced nation and the developing nation. It is shown that this internal combustion engine has extremely high thermal efficiency. Diesel engines are a very effective target for reducing global warming exhaust gas emissions, and they are trying to replace petroleum fuel with diesel engines. The operation of a diesel engine using an OTD system characterized by lubrication and combustion through consumption is realized.

[0005] Generally, when using vegetable oil fuel in a diesel engine, a major problem is its extremely high viscosity, and it is said that it is necessary to reduce the viscosity by using some method. Examples of the method include fuel heating, blending with light oil, and reaction with alcohol to return to monoesterified fuel. However, these methods require other heats of heating, and require much labor and effort. Therefore, a new fuel supply method for diesel engines was developed.This method does not require much labor, reduces the viscosity of vegetable oil fuel, and makes it possible to operate diesel engines. The biggest feature is that it is vegetable oil. Vegetable oil is used as lubricating oil, and high-temperature, low-viscosity vegetable oil is continuously pumped up from the crankcase of the engine with a fuel pump. By using this as a fuel oil, the viscosity of the vegetable oil fuel is reduced without the need for extra heating heat. That is. In addition, the diesel engine crankcase has a mechanism that always replenishes new vegetable oil, and has the advantage that one-through consumption does not require replacement of lubricating oil. The operation of diesel engines using the OTD system that uses vegetable oil has been widely used in advanced nations, which already have a large number of practical units, without having to use energy resources, including environmental and resource measures. It will be easier for developing countries to obtain power from only their own products, which will contribute to the establishment of the cycle energy industry and the development of related technology industries.

The operation of a diesel engine using this OTD system does not use any petroleum oil as fuel oil or lubricating oil, but operates the diesel engine using only vegetable oil, which is a biomass fuel. The features of this system are as follows: (1) No petroleum-based fuel oil is used. (2) Fuel oil and lubricating oil are one vegetable oil and fat. (3) No need to change the lubricating oil. (4) The problem of high viscosity, which is a problem when vegetable oil is used as a fuel for a diesel engine, can be improved. The drawing shows the configuration of the OTD system. This system has a diesel engine 1, an oil tank 2, an oil pump 3, an oil pump 4, an oil level adjuster 4, a fuel pump 5, a lubricating filter 6, and a lubricating filter 7. The system has a fuel filter 8 and a lubrication pump 8. The oil tank 2 is filled with vegetable oil for fuel, and the diesel engine 1
Send oil to The amount of oil stored in the engine crankcase,
The liquid level is adjusted by controlling the oil supply by the oil amount adjuster 4 so that the oil amount in the crankcase is always adjusted.
The amount of oil consumed as fuel is supplied as lubricating new oil. The vegetable oil supplied to the crankcase passes through a lubricating filter 6 and is subjected to forced lubrication in the engine by a lubricating pump 8, and during this lubrication, absorbs engine heat and returns to the crankcase. In the crankcase, the high-temperature heat of the high-pressure gas leaking from the piston ring is absorbed, turned into high-temperature, low-viscosity oil, drawn by the fuel pump, and injected into the combustion chamber. The OTD system uses the vegetable oil to perform lubrication and absorbs the heat generated by the engine to a high temperature and a low viscosity, which is consumed as fuel. This system consists of the lubrication process from the use of vegetable oil to the combustion process. This is the driving method of the diesel engine.

[0007] Regarding the selection of vegetable oil fuels to replace petroleum fuels conventionally or currently provided to diesel engines, the OTD system in this order allows practical use of vegetable oils in general, In some cases, the viscosity of the viscous substance needs to be changed by some kind of blending or by heating. In the selection of fuel vegetable oil by the OTD system, rapeseed oil is used as a standard product. It is rooted in its adaptability to flammability and production cultivation in Japan. Regarding diesel operation with vegetable oil, examples of development research have already been introduced and published in papers, and it has been proved that rapeseed oil is a stable alternative fuel and has good lubrication in the refueling system. Have been.

[0008]

According to the present invention, the combustion oil and the lubricating oil can be provided with the same oil quality. The consumption of fuel by driving in the OTD system is
Since the lubricating oil is constantly replenished with new oil, it is easy to maintain the freshness of the lubricating oil. The through consumption of the OTD system eliminates lubrication waste oil and eliminates the waste of conventional waste oil treatment. Absorption of engine heat during the lubrication process results in heat recovery by heating the fuel oil, and the heating reduces the viscosity of the vegetable oil, thereby refining the injected fuel.
Life extension of finite petroleum resources and mitigation of global environmental pollution by petroleum fuel exhaust gas. The OTD system is ideal for operation at a newly designed engine, but it is easy to use it by installing additional equipment on existing models that have already been widely used and used, or by modifying and maintaining it. Absent.

OT that enables operation with 100% vegetable oil
The widespread use of diesel engines by the D system will promote the expansion of the renewable energy industry. By renewable energy,
Securing permanent power energy enables countries that do not have oil resources to be self-sufficient in power energy. Promotion of greening of degraded land and revitalization of idle land and fallow land are expected through the cultivation oil field development project, and the technology for extracting vegetable oil has been improved more than ever before. Done.
