      In order to reduce adverse effects on human health and improve the global environment, when used as a fuel for automobiles, combustion efficiency can be improved easily and easily, and significant purification of harmful substances in exhaust gas can be achieved. Development of fuel additives for automobiles that can reduce fuel consumption is desired.

  In order to solve the above-mentioned problems, hinoki oil obtained by atmospheric distillation of one or more tree trunks selected from cypress family trees to ganlin, diesel light oil and heavy oil for automobiles It was solved by adding cypress tree oil.

    First, (1) diesel fuel oil, (2) regular gasoline for small vehicles, and (3) high-octane gasoline for large vehicles, the fuel efficiency when the fuel additive for automobiles of the present invention is not added and when it is added. A comparison was made.

    (1) In the case of diesel diesel oil, 16.7 km / liter (hereinafter referred to as km / L) when the fuel additive for automobiles of the present invention is not added. In contrast, when 0.1% by volume of the fuel additive for automobiles of the present invention is added, it is 18.3 km / L, an increase of about 11%.

    In the case of regular gasoline for small cars by Mitsubishi Minica (displacement of 360 cc) of the year 2000, this is compared to 15.0 km / L when the fuel additive for automobiles of the present invention is not added. When 0.1% by volume of the fuel additive for automobiles of the invention is added, it is 19.0 km / L, an increase of about 27%.

Furthermore, after adding 0.1% by volume of the automobile fuel additive of the present invention and running again after adding 0.1% by volume of the automobile fuel additive of the present invention, it is 23.5 km / L, which is about 57. % Increase.
This is considered that when the vehicle fuel additive of the present invention was added and the vehicle was run, the fuel tank and the piping were cleaned to further improve the combustion effect.

    According to Toyota Celsior (displacement 4200cc) of year 2001, high-octane gasoline for large-sized automobiles is 5.1 km / L when the fuel additive for automobiles of the present invention is not added. When 0.1% by volume of the fuel additive for automobiles of the invention is added, it is 10.5 km / L, an increase of about 106%.

    Next, with respect to harmful exhaust generated after burning diesel diesel oil, a comparative measurement between the case where the fuel additive for automobiles of the present invention is not added and the case where the fuel additive for automobiles of the present invention is added is used as a measurement vehicle. Type 2FD25, Frame 2Fd25-13422), using an opacimeter (model RTM215J, manufactured by BOSCH) as a measuring instrument, contamination by particulate matter (PM) among harmful substances contained in automobile exhaust gas from diesel vehicles The degree was measured and compared.

    Table 1 shows (1) diesel diesel oil only, (2) 0.1% by volume of the automobile fuel additive of the present invention is added to diesel diesel oil, and (3) automobile fuel additive of the present invention is added to diesel diesel oil 0 5 shows the results of measuring the exhaust gas of the opacimeter when adding 5% by volume and (4) 1.0% by volume of the fuel additive for automobiles of the present invention to diesel diesel oil.

The opacimeter allows light to pass through the exhaust gas collected from the exhaust pipe and measures the degree of exhaust gas contamination (light absorption coefficient [1 / m]) from PM from the transmittance to determine the degree of exhaust gas purification.
The light absorption coefficient regulation value for 30% graphite regulated vehicles is 1.01 (1 / m).
