preparation example Construction

[0026] The preparation method of the above-mentioned fuel of the present invention comprises the following steps: measure each component according to the volume ratio, first add ABE (3:6:1) into the diesel oil to form a completely miscible mixed solution, and then add water to the mixed solution under stirring until the water capacity in the mixture reaches the maximum value, so as to avoid stratification or turbidity, that is, to reconcile the mixed fuel.

[0027] The kinematic viscosity of the novel mixed fuel containing ABE (3:6:1) and water provided by the test is 1.52-3.23mm 2 / s, meeting the fuel viscosity range suitable for traditional diesel engines.

[0028] Depend on figure 1 — Figure 4 It can be seen that when the blending ratio of ABE (3:6:1) is between 10% and 90%, diesel oil and ABE (3:6:1) can be well miscible at 0-60°C, and the higher the temperature, the more The more water, the higher the temperature, the greater the water capacity. At the same time, wit...

Abstract

The invention discloses an acetone-butanol-ethanol (ABE) / water / diesel oil mixed fuel suitable for diesel engines. The ABE / water / diesel oil mixed fuel consists of acetone-butanol-ethanol (A:B:E is 3:6:1), diesel oil and water. According to the ABE / water / diesel oil mixed fuel provided by the invention, the characteristic that diesel oil and water are immiscible is regulated through ABE (3:6:1), andthe fuel characteristic of the mixed fuel is improved, so that the mixed fuel retains the advantages of oxygen-containing fuel, recovery cost of ABE (3:6:1) fuel is reduced, and therefore an application of the mixed fuel to diesel engines is achieved. Due to the fact that ethanol has high water absorption capacity and the high oxygen content of the blender ABE (3:6:1) is combined, pollutant emission in a combustion process can be reduced. In addition, all components in the mixed fuel have backgrounds of biomass energy, are renewable and are convenient to obtain, so that energy crisis can be relieved to a certain extent.

Description

technical field [0001] The invention relates to the field of renewable alternative energy sources for internal combustion engines, in particular to a novel mixed fuel suitable for diesel engines. Background technique [0002] In recent years, due to the shortage of fossil fuels, the continuous deterioration of the global environment, and the increasing demand for energy security and diversity, people have greatly increased their interest in developing clean and sustainable energy sources. Renewable fuels such as biodiesel and biobutanol have attracted great attention due to their ability to be produced from biomass and their relatively low levels of polluting emissions. Among them, oxygenated fuel burns more fully and emits lower emissions. Extensive experiments have investigated the emissions and energy performance of diesel engines fueled with oxygenates such as methanol, ethanol, propanol, butanol, pentanol, and ketones or ethers, which are renewable and The performance...
