Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention [0001]
  • This invention relates to a low pollution fuel used for diesel engines and the like. [0002]
  • 2. Related Art [0003]
  • A diesel engine is used in many automotive vehicles, electric power generating apparatuses and the like. Light oil, heavy oil and the like are used for such a diesel engine as its fuel. The diesel engine, which uses light oil, heavy oil and the like as its fuel, discharges exhaust gas containing a large quantity of noxious matters such as suspended particulate matters, nitrogen oxides, hydrocarbons, aldehydes and the like. Such exhaust gas discharged from the diesel engine often creates the problem of air pollution and various diseases resulting therefrom. [0004]
  • It is extremely difficult to completely combust the light oil and heavy oil currently used as fuel for the diesel engine by the compression explosion means which is a diesel engine-specific combustion style. This is the reason why the above-mentioned exhaust gas problem occurs. [0005]
  • An attempt is made with a view to solve the above-mentioned exhaust gas problem, in which various types of exhaust gas processing devices equipped with a filter function and a secondary combustion function are attached to an exhaust gas outlet port. However, this technology still has such shortcomings that performance is degraded due to aging deterioration and the price is high. In addition, too many technical problems are involved and so it is hopeless to efficiently remove the above-mentioned air pollution factors. Therefore, this attempt is not yet successful for fundamentally solving the outstanding problem. [0006]
    • SUMMARY OF THE INVENTION
  • It is, therefore, an object of the present invention to provide, in order to solve the above-mentioned problem, a low pollution fuel which can take the place of the currently used light oil and heavy oil which are found to be the cause of noxious exhaust matter instead of solving the problem by the above-mentioned symptomatic measures, which is extremely high in combustion efficiency and which is also high in economical efficiency. [0007]
  • From one aspect of the present invention, there is provided a low pollution fuel in which an ethylene glycol based compound having a group of CH2CH2 in a molecular formula is blended with a liquid hydrocarbon. [0008]
  • From another aspect of the invention, there is provided a low pollution fuel in which a diethylene glycol based compound having a group of CH2CH2OCH2CH2 in a molecular formula is blended with a liquid hydrocarbon as represented by the light oil and heavy oil. [0009]
  • From a further aspect of the invention, there is provided a low pollution fuel in which a compound generally expressed by a molecular formula of ROOC—CH═CH—COOR is blended with a liquid hydrocarbon. [0010]
  • In the above fuel, the ethylene glycol based compound or the diethylene glycol based compound, or the compound generally expressed by the molecular formula of ROOC—CH═CH—COOR is combusted itself while synergistically increasing the effect, thereby remarkably reducing imperfect combustion.[0011]
