Abstract

The invention discloses methanol diesel fuel, prepared from the following components in terms of parts by weight: 680 to 730 parts of diesel fuel, 140 to 160 parts of methanol, 25 to 30 parts of diethoxymethane, 6 to 8 parts of dimethylacetamide, 10 to 12 parts of secondary alcohol ethoxylate, 13 to 15 parts of caprylic capric triglyceride, 12 to 15 parts of myristyltrimethylammonium bromide, 30 to 50 parts of propylene glycol monomethyl ether, 3 to 4 parts of sec-butyl acetate, 12 to 15 parts of coconut oil amine polyoxyethylene ether, 15 to 18 parts of propargyl alcohol and 4 to 5 parts of nano-magnesium hydroxide. The methanol diesel fuel disclosed by the invention has the features of homogeneous phase, transparency, stable property and long storage period, and can be widely applied to vehicles, boilers, ships and the like. The methanol diesel fuel disclosed by the invention has the advantages that the effects of obvious energy saving, obvious environmental friendliness and excellent combustion performance are achieved; especially compared with conventional #0 diesel fuel, the maximum firing pressure in an cylinder is increased, the combustion timing is delayed, the peak value of heat releasing rate is increased, and the PM (Particulate Matter) emission is obviously reduced at the same time.

Description

technical field [0001] The invention relates to the technical field of fuel oil, in particular to methanol diesel and a preparation method thereof. Background technique [0002] The formation of fuel mixture in diesel vehicles is carried out in the combustion chamber of the engine. Diesel is injected into the combustion chamber at high pressure, compressed and ignited, and then burned while spraying. This way of working determines that the mixture of diesel and air is not uniform, and there will inevitably be local oxygen deficiency or local oxygen enrichment. When oil is exposed to high temperature and lack of oxygen, it is easy to carbonize and form soot. The adjustment of diesel vehicle load is controlled by changing the fuel injection quantity. The mixture of diesel vehicles is always in a relatively lean state, that is to say, there is always a surplus of air in the combustion chamber of the diesel engine. The excess air tends to produce nitrogen oxides (NOx) under h...
