Problems solved by technology

[0005] However, the study found that with the increase of the methanol content in the methanol-gasoline mixture, the compatibility becomes worse, and the phase separation temperature rises rapidly. When the methanol content reaches 40%, the phase separation temperature reaches the maximum; when the methanol content continues to increase, the phase depth The performance becomes better, and the phase separation temperature drops rapidly

Abstract

The invention relates the car engine composite fuel, comprising 30-90% petrol, 10-70% methanol, 0.5 -3% assisting solvent. The assisting solvent comprises 30-60% oleic acid or naphthenic acid or lactic acid, 1-3% orthotoluidine or triethylamine, 806-11% tuwen, 25-63% benzene, and 1% anhydrous sodium sulfate. The product is environmental protection and cleaning. The methanol petrol fuel reduces CO and HC concentrations in vehicle exhaust gas, cleaning air and improving contamination condition. The invention has advantages of simple technology and low cost.

Description

technical field [0001] The invention relates to a composite fuel for automobile engines containing methanol, in particular to a methanol-gasoline fuel for automobile engines containing methanol. Background technique [0002] At present, there is a shortage of crude oil in the world, the rapid development of the automobile industry, and the continuous rise of oil prices, especially in recent years. It is the mainstream of the world and concerns the international people's livelihood. [0003] Gasoline has always been the traditional fuel for automobiles, but its source—petroleum is a non-renewable resource. It is predicted that, based on the current growth rate of oil production, the world's oil reserves will be consumed in about 2015-2035 80% of the total, therefore, it is imperative to find a new vehicle fuel. Methanol has the diversity of raw materials for synthesis, has low pollution when burned, and has a high octane number. Therefore, it is most promising to become an ...
