ether based fuel

Abstract

A clean ether-based fuel comprises dimethyl ether and ethanol. The ether-based fuel can replace gasoline in automobiles or other vehicles or power equipments having gasoline engines. A mixed fuel comprising the ether-based fuel and at least one other fuel selected from the group consisting of gasoline and solvent oil is also provided.

Description

technical field [0001] The invention relates to a new type of clean fuel, in particular, a clean ether-based fuel. The ether-based fuel contains dimethyl ether and ethanol. More specifically, the ether-based fuel may consist solely of dimethyl ether and ethanol. The present invention also relates to a mixed fuel comprising the ether-based fuel of the present invention and at least one other fuel selected from gasoline and mineral spirits. Background technique [0002] As we all know, petroleum, as a non-renewable resource, plays an indispensable role in a country's social life and national defense construction. With the continuous improvement of people's living standards in our country, cars have gradually entered the families of ordinary people. For example, Beijing has now entered the era of 4 million cars. Therefore, as the number of cars increases, so does the demand for gasoline. my country's crude oil production has been far from meeting the needs of the vigorous ...

AI Technical Summary

Problems solved by technology

[0008] Although the standards for methanol gasoline have been promulgated and implemented, there are still some problems with methanol gasoline due to the material characteristics of methanol: first, the volatility of methanol relative to gasoline components is poor, resulting in difficulties in cold starting and insufficient combustion of engines using methanol gasoline; Methanol and gasoline have poor miscibility, short shelf life, and easy to deteriorate and stratify; third, the substitution ratio is low (that is, about 1.6-1.7 parts of methanol needs to be used to replace 1 part of gasoline), and fourth, if the engine structure is not changed, methanol gasoline is now Insufficient combustion and lack of power in some engines

However, ethanol gasoline also has some problems, such as easy moisture absorption, short shelf life due to water stratification, low substitution ratio and insufficient power.
