Problems solved by technology

2010,62(1):9-14N) Its research only involves the method of transesterification, and the problem of energy loss in the transesterification process has not been resolved
However, the current research on PODE-containing blended fuels is limited to the fields of biodiesel and diesel, and there is no report on its application to corn oil fuel systems.

preparation example Construction

[0023] 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 methanol into corn oil to form an incomplete miscible mixed solution, then add a certain volume of PODE into the mixed solution under stirring and mix evenly , so that it can be dissolved to obtain a blended fuel. The mixing temperature is preferably between 35°C and 45°C.

[0024] By calculating the kinematic viscosity of the novel mixed fuel containing methanol provided by the present invention is 2.24-4.44mm 2 / s, meeting the fuel viscosity range suitable for traditional diesel engines. The novel mixed fuel provided by the invention, corn oil / methanol / PODE has good mutual solubility, and the obtained mixed fuel can be stored at 40 degrees centigrade for a long time without delamination.

[0025] At 40°C, when the blending ratio of methanol is between 10% and 90%, the miscibility of corn oil and me...

Abstract

The invention discloses corn oil / methanol / PODE mixed fuel suitable for a diesel engine. Components are mixed according to a certain volume ratio within a temperature range of 35-45 DEG C through a mixing technical means to obtain the mixed fuel. Methanol is firstly added into corn oil to form an incompletely intermiscible mixed solution, then PODE is added into the mixed solution while stirring, and the mixture is uniformly mixed to obtain the mixed fuel. The obtained mixed fuel is stable and homogeneous, and the overall viscosity of the system meets the requirements of traditional diesel fuel. The methanol is added, so that the combustion efficiency can be improved, and the emission of nitrogen oxides (NOx) and particulate matters (PM) is reduced. The PODE is added, so that the cetane number of a corn oil-methanol basic system can be improved to a certain extent, the overall density of a fuel system is improved, pressure wave transmission in the fuel injection process is faster, and therefore the input capacity and the power performance of an 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] Vegetable oil, as a relatively easy-to-obtain organic macromolecular substance, has been extensively studied. Oils treated by certain methods have close homologous physical properties to diesel fuel, making them potentially useful as biofuels. A variety of vegetable oils have been considered as potential alternative fuels, such as soybean, rapeseed, corn and palm oil. Among them, corn oil is the oil extracted from corn germ, so it is also called corn germ oil, and the advantages of using corn oil to produce biodiesel are obvious: corn oil as a raw material is easy to get and has a wide range of sources; it is beneficial to the soil Optimization; by-products have high economic value; can effectively protect the environment. However, the high viscosity...
