Benefits of technology

[0008]According to a second aspect of the present invention, a method for enhancing combustion efficiency of a liquid fuel includes: adding a sublimatable organic compound in a liquid fuel, wherein the sublimatable organic compound has a sublimation point lower than 45° C. at atmospheric pressure and includes a skeleton selected from the group consisting of bicycloheptane, indane, pyrone, cyclopropane, cyclobutane, cyclopentane, cyclohexane, cycloheptane, cyclooctane, and benzene.

Problems solved by technology

However, exposure to MEBT for a long time is likely to cause tissue / organ damage or cancer.
However, since camphor and naphthalene have relatively high melting points, i.e., 176-180° C. and 179.75° C., respective, they posses poor burning characteristics, thereby resulting in heavy smoke and carbon deposits.

Examples 1 to 7 (E1-E7)

[0068]2.5 grams of a sublimatable organic compound of the present invention was added in a liquid fuel having a predetermined volume so as to form a liquid fuel composition of the present invention. The liquid fuel composition of the present invention was filled in the fuel tank of a vehicle which was subsequently tested to run on a general road in Shenzhen, China with a varying speed. The species of the sublimatable organic compound, the liquid fuel, the amounts of the liquid fuel, the tested vehicle, and the total volume displaced by a cylinder / cylinders of the engine through one revolution, horsepower, and manufacture year of the vehicle for each of Examples 1 to 7 are shown in Table 1. The running mileage of each of Examples 1 to 7 was recorded and is shown in Table 2.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority of Taiwanese application No. 099138652, filed on Nov. 10, 2010.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]This invention relates to a liquid fuel composition and a method for enhancing combustion efficiency of a liquid fuel using a sublimatable organic compound.[0004]2. Description of the Related Art[0005]As the global energy crisis and environmental pollution become more serious, scientists are devoting efforts to investigate alternative energy resources as well as develop methods for enhancing the combustion efficiency and reducing the usage of present energy sources such as fossil fuels. For the latter purpose, aside from modifying the mechanical structure of combustion equipment, use of fuel additives to improve combustion efficiency is also widely employed. For example, methyl tertiarybutyl ether (MEBT) has been added in unleaded gasoline in an amount of about 4-10 wt % to achieve ...
