Problems solved by technology

Alcohol fuels include methanol, ethanol, etc., but alcohol fuels have disadvantages such as low-temperature stratification and moisture stratification, and there are many difficulties in transportation, storage, and use. Therefore, ether fuels have received extensive attention
[0004] Dimethyl ether is the first to open the application of ether blended fuels, but because it is gaseous at normal temperature and pressure, it has encountered a bottleneck that is difficult to apply
In short, benzene, toluene, xylene, etc. are substances that are restricted in the quality of oil products, so they are not widely used

Abstract

The invention discloses a dimethoxymethane (DMM) composition used as blended fuel for a vehicle. The DMM composition comprises the components in parts by weight: 88-95 parts of DMM, 5-8 parts of tert-amyl methyl ether (TAME) and 2-5 parts of functional additive, wherein the functional additive comprises the following raw materials in parts by weight: 50-65 parts of polyisobutylene succinimide, 30-40 parts of fatty acid and 5-10 parts of cerium oxide. The DMM composition disclosed by the invention is used as the blended fuel for the vehicle, so that the consumption of gasoline can be reduced, the heat utilization ratio of fuel oil can be increased, the emission of harmful gas in automobile exhaust can be reduced, and the defect existing when DMM is independently used as the blended fuel is overcome.

Description

technical field [0001] The invention relates to a blending fuel for vehicles, in particular to a dimethoxymethane composition. Background technique [0002] In order to solve the emission of harmful gases in automobile exhaust, improving the quality of automobile oil products is the most effective method at present. So far, there are two main ways to improve the quality of automobile oil, one is to improve the quality of oil through refining, and the other is to improve the quality of fuel by adding blended fuel or additives. [0003] Adding blended fuel to automobile fuel is the most effective way to greatly improve fuel quality and reduce harmful gas emissions in tail gas. Alcohol fuels and ether fuels are currently used more in blending fuels. Alcohol fuels include methanol, ethanol, etc., but alcohol fuels have disadvantages such as low-temperature stratification and moisture stratification, and there are many difficulties in transportation, storage, and use. Therefore...
