preparation example Construction

[0027] The preparation method of the fuel of the present invention comprises the following steps: measure each component according to the volume ratio, first add ethanol to palm oil to form an incomplete miscible mixed solution, and then add n-butanol to the mixed solution under stirring and mix evenly, namely Have to reconcile the fuel mix. This blended fuel is recommended to be blended at a temperature range of 30°C-60°C.

[0028] The kinematic viscosity of the novel mixed fuel containing ethanol provided by the invention is 2.08-4.20mm 2 / s, meeting the fuel viscosity range of 2.0-4.5mm suitable for traditional diesel engines 2 / s.

[0029] The novel mixed fuel provided by the invention has good mutual solubility of palm oil / ethanol / n-butanol, and the obtained mixed fuel has no stratification during long-term storage.

[0030] At 40°C, when the blending ratio of ethanol is between 10% and 90%, the miscibility of palm oil and ethanol cannot be realized. but from figure ...

Abstract

The invention discloses a palm oil / ethanol / n-butyl alcohol mixed fuel suitable for a diesel engine. The palm oil / ethanol / n-butyl alcohol mixed fuel comprises, by volume, 41-65% of ethanol, 26-41% of palm oil and 7-18% of n-butyl alcohol; and the obtained mixed fuel is stable and homogeneous, and the overall viscosity of the system meets the requirements of traditional diesel fuel. By adding ethanol, the combustion efficiency can be improved, and the emission of nitrogen oxides (NOx) and particulate matters (PM) can be reduced. By adding n-butyl alcohol, the cetane number of a palm oil and ethanol basic system can be improved to a certain extent, the overall density of a combustion system is improved, and pressure wave transmission in the fuel injection process is fast, so the input capacity and the power performance of the energy engine are improved.

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] Palm oil is pressed from the fruit of the oil palm tree. Palm oil has the same advantages of oxidation stability and relatively low volatility as other vegetable oils, but the high viscosity and density of palm oil has become a prominent defect in its application as fuel. Therefore, long-term use of palm oil can lead to engine durability problems such as coking of fuel injectors, poor fuel atomization, higher NOx emissions, and sticking of piston rings. The use of palm oil as an alternative fuel to diesel has been slow to progress due to its high viscosity. [0003] At present, the main method of using palm oil as fuel is to produce biodiesel through transesterification. The blending of biodiesel with diesel and alcohols is mainly used in the prepara...
