Problems solved by technology

However, it cannot be used as a complete fuel product yet, but as an additive to diesel fuel or as a mixture with light oil in automobiles
Therefore, the fuel dependence of diesel engines on light oil is still high in the prior art

Embodiment 1

[0041] The following components were mixed with each other to obtain a fuel composition for an internal combustion engine of the present invention, and the properties were tested. The test results are shown in the table below. It will be appreciated that the compositions of the present invention have an octane rating as high as 96 despite not containing a separate octane booster.

[0042] 1) 4% by weight of Aromatic-100 as aromatic hydrocarbon solvent

[0043] 2) 16% by weight of toluene

[0044] 3) 10% by weight xylene

[0045] 4) 13% by weight bioethanol

[0046] 5) 4% by weight isopropanol

[0047] 6) 2% by weight isobutanol

[0048] 7) 51 wt% gasoline as industrial gasoline

Embodiment 2

[0050] The steps of Example 1 were repeated, except that a mixed fuel composed of 10% by weight of the fuel composition prepared in Example 1 and 90% by weight of unleaded gasoline with an octane number of 93 was prepared, and the performance was tested. The test results are shown in the table below.

Embodiment 3

[0052] The steps of Example 1 were repeated, except that a mixed fuel composed of 40% by weight of the fuel composition prepared in Example 1 and 60% by weight of unleaded gasoline with an octane number of 93 was prepared, and the performance was tested. The test results are shown in the table below.

Abstract

Disclosed herein is a fuel composition for internal combustion engines, which comprises: a) 1-45 wt % of toluene; b) 1-45 wt % of xylene; c) 1-85 wt % of bioethanol, ethanol or a mixture thereof ; d) 10-69 wt % of industrial gasoline; e) 1-19 wt % of aromatic solvent; f) 1-13 wt % of isopropanol; and g) 1- 12 wt % of isobutanol. Also, the fuel composition can additionally contain isopentane to maximize the heating value of the composition upon burning, and can additionally contain, as an additive, a corrosion inhibitor which is conventionally added to liquid fuel in order to prevent the corrosion of internal combustion engines. The disclosed fuel shows a remarkable reduction in air pollution, compared to the existing gasoline, and, at the same time, has improved power performance, and thus is useful as alternative fuel having economic efficiency.

Description

technical field [0001] The present invention relates to a fuel composition for an internal combustion engine, and more particularly to a fuel composition for an alternative fuel for an internal combustion engine, which can be used not only for a gasoline engine using gasoline as a fuel but also for a diesel engine using light oil as a fuel. Background technique [0002] Due to the depletion of oil resources caused by the "oil shock" in the 1970s, and environmental pollution from fossil fuels has become a worldwide problem, it is not an exaggeration to say that the world today is struggling with energy and the environment. In order to cope with the increasingly strengthened internal environmental regulations ("Kyoto Protocol"), especially countries without oil resources (such as South Korea) should pay attention to the development of alternative fuels and should accelerate the development of alternative fuels. [0003] However, gasoline is widely used as a fuel for internal c...
